connections for the plumbing of engine coolant to heat an onboard water heater The water heater should be mounted in a convenient location either in a high or low position in relation to the engine so that the con255necting hoses from the heater to the engine can run in a rea255sonably direct line without any loops which might trap air Hoses should rise continuously from their low point at the heater to the engine so that air will rise naturally from the heater to the engine If trapped air is able to rise to the heater then an air bleed petcock must be installed at the higher fit255ting on the heater for bleeding air while filling the system NOTE If any portion of the heating circuit rises above the engines closed cooling system pressure cap then a pressur255ized aluminumremote expansion lank must be installed in the circuit to become the highest point Tee the remote expan255sion tank into the heater circuit choosing the higher of the Mo connections for the return Tee at the heater and plumb a single line up to the tanks location and the other back to the engines return Instalthe remote expansion lank in a con255venient location so the fresh water coolant level can easily be checked The remote expansion lank will now serve as a check and system fill point The plastic coolant recovery lank is not used when the remote expansion lank kit is installed since this tank serves the same function HEATER ABOVE THE ENGINE REMOTE EXPANSION l TANK j 1260 I t WATER HEATER THERMOSTAT HOUSING 25 The pressure cap on the engines manifold should be installed after the engines cooling system is filled with coolant Finish filling the cooling system from the remote tank after the system is filled and is free of air and exhibits good coolant circulation During engine operation checking the engines coolant should be done at the remote tank and not at the engine manifold cap The hose connection from the heater to the remote expansion tank should be routed and supported so it rises continuously from the heater to the tank enabling any air in the system to rise up to the tank and out of the system NOTE Air bleed petcocks are located on the engines heat exchanger and on the thermostat housing Open these pet255cocks when filling the enginesJresh water SSlel7l to allmA air in the coolant circuil O escape Close lighlV after al the air is removed THERMOSTAT HOUSING HEATER

on the base mounting bolt to the left or right as required 3 Tighten the base mounting bolt and the adjusting strap bolL 4 Operate the engine for about 5 minutes at idle then shut down and recheck belt tension BElT TENSION BATTERY CARE Review the manufacturers and then estab255lish a systematic maintenance schedule for your engine start255ing batteries and house batteries o Monitor your voltmeter for proper charging during engine operation o Check the electrolyte level and specific gravity with a hydrometer o Use only distilled water to bring electrolytes to a proper lcvel o Make certain that battery cable connections are clean and tight to the battery posts and to your engineo Keep your batteries clean and free of corrosion 21 A WARNING Sulfuric acid in lead batteries can cause severe burns on skin and damage clothing Wear protective gear A CAUTION When quick charging the battery with an external charger be sure to disconnect the battery cables from the battery so the quick charge doesnt damage the alternator diodes GLOW PLUGS The glow plug is a small heater installed in each chamber They run off the engine starting bauery and become red hot when activated The glow plugs are wired through the preheat solenoid When preheat is pressed at the control panel this solenoid should click on and the glow plug terminal should begin to get hal Glow plugs can be checked by unscrewing and holding them against a good ground engine blockand turning them on The tip should glow red hot You can also usc an ammeter to test the power drain 8 to 9 amps per plugor an ohmmeter to test resistance I to 12 ohmsA WARNING These glow plugs will become very hot to the touch Be careful not to burn your fingers when testing plugs Reinstall the plugs in the engine and test them again The plugs should get very hot at the terminal endwith 20 to 25 seconds If the plugs dont heat up quickly check for a short circuit A CAUTION Do not keep glow plug on for more than 30 seconds GLOW PLUG TERMINAL PREHEAT GLOW PLUGS CENTRE SHAFT J SILICON CAP y TUBE FROM PREHEAT SOLENOID AdobeUCSDC ELECTRICAL SYSTEM DESCRIPTION The charging system consists of an alternator with a mounted voltage regulator an engine DC wiring harness a mounted DC circuil breaker and a battery and connection wires Because of the use of integrated circuits Iesthe electronic voltage regulator is very compact and is mounted internally or on the back of the alternator Alternator If you suspect that the alternator is not producing enough voltage to charge the engines battery check the following A WARNING A failed alternator can becDme very hDt Do nDt touch until the alternator has cODled dDwn o Make certain your alternator is securely mounted o Check the drive belts for proper tension o Inspect for loose or disconnected wires at the alternator NOTE An isolator with a diode a solenoid or a battery selector switch is usually mounted in the circuit to isolate the balleries so the starting ballery is not discharged along with the house batteries If the isolator is charging the slarling ballery but not the house ballery the alternator is OK and the problem is in the ballery charging circuit A WARNING Shut Dff the engine battery switch Dr discDnnect from the battery when wDrking Dn the engine electrical system Checking for Proper Voltage If you suspect the alternator has failed perform the following tests with the engine off 1 Using a voltmeter connect the voltmeter red wire clip to the output terminal B 2 Connect the voltmeter negative wire to any ground on the engine 3 Check the battery voltage It should read 12 to 12 volts 4 Check the voltage between the alternator positive minai B and any engine ground If the circuit is good the voltage at the alternator should be the same as the battery unless theres an isolator in the circuit then the reading would be zeroA CAUTION TD aVDid damage tD the battery charging circuit never shut Dff the engine battery SWitch when the engine is running 20 A WARNING Before starting the engine make certain that everyone is clear Df mDving parts Keep away frDm sheaves and belts during test prDcedures 5 Start the engine 6 The voltage reading for a properly operating alternator should be between 135 and 145 volts If your alternator is overor undercharging have it repaired at a reliable service shop NOTE Before removing the alternator for repair use your voltmeter to ensure that 12 volts DC excitation is preselll at the R terminal if the previous lest showed ollly ballery volt255age at the B output terminal 14 PINK1IlUE 14 PINK8LUE 1U

causing fuel problems you should have an authorized dealer correct these problems Then use a diesel fuel biocide to sterilize the fuel follow the While the likelihood of having to service the fuel system at sea is slim the possibility does exist Therefore we recom255mend that banjo washers injector seat washers and a fuel fil255ter be earned on board at all times Purchase needed spares from your local UNIVERSAL dealer or distributor If a leak should develop at a banjo washer that cannot be corrected by a simple tightening of the fitting replace the sealing washer PRIMING BLEEDINGTHE FUEL SYSTEM The onengine fuel system is virtually self priming Under ordinary circumstances the engines electric fuel lift pump which is energized by the key switchpreheat button will supply a continuous flow of fuel from the tank This fuel is drawn through the fuelwater separator to the engine lift pump the primary spinon fuel filter and the injection pump A WARNING Do not allow smoking or open flames near the fuel system when servicing Also provide proper ventilation TO FUEL FILTER FROM FUEL TANK 1LCHECK AND CLEAN filTER AT OIL CHANGE TO FUEl FILTER FUEL LIFT PUMPS FROM FUEL TANK 19 If it becomes necessary to bleed air from the system use the following procedure Loosen all the high pressure injector lines not injectorsand crank the engine starter motor as fue I spurts from between the nut and the line tighten the injector Jines in sequence and then tighten the bleed screw NOTE Do not attempt this procedure on a hot engine A WARNING Always wear protective clothing safety glasses and gloves when bleeding high pressure injector lines fiLTER ELEMENT Air CANISTER AIR ENGINE M2673S8 SHOWNSome UNIVERSAL engines use a replaceable air filter cle255ment wrapped around a metal canister This element can be removed and brushed off or cleaned with an air hose When it become too contaminated it can be replaced The canister with its interior element should also be removed and cleaned periodically Simply wash the assembled unit in a nonflarn mabIe cleaning solvent Use this same cleaning procedure for other UNIVERSAL air cleaners that use a similar type canis255ter NOTE To operate efficiently a diesel engine must intake a continuous volume of clear air Hard starting an erratic idle alld black exhaust smoke are all symptoms of a restricted air intake clockwise carefully REMOTE OIL FILTER INSTALLATION This popular accessory is used to relocate the engines oil fil255ter from the engine to a more convenient location such as an engine room bulkhead NOTE Refer to the ENGINE OIL

warm Remove the oil drain hose from its attachment bracket and lower it into a container and allow the oil to drain or attach a pump to the end of the drain hose and pump out the old oil Make sure the oil drain hose is capped and properly secured in its holder after all the old oil has been drained NOTE Thread size for the lube oil drain hose capped end is 114 NPT Always observe the old oil as it is removed A yellowgray emulsion indicates the presence of water in the oil Although this condition is rare it does require prompt attention to pre255vent serious damage Call a competent mechanic if water is present in the oiL Raw water present in the oil can be the result of a fault in the exhaust system attached to the engine andor a siphoning of raw water through the raw water cool255ing circuit into the exhaust filling the engine This problem is often caused by the poor location or the ack of an anti255siphon valve See UNIVERSALS Installation Manual Replacing the Oil Filter When removing the used oil filter you may find it helpful and cleaner to punch a hole in the upper and lower portion of the old filter to drain the oil from it into a container before removing it This helps to lessen spillage NOTE Do not punch this hole without first loosening he filter to make certain it will come off An automotive filter wrench should be helpful in removing the old oil filter Place some paper towels and a plastic bag around the filter when unscrewing it to catch any oil left in the filter Inspect the old oil tilter as it is removed to make sure that the ruhber scaling gasket comes off with the old oil filter If this rubber sealing gasket remains sealed against the engine block gently remove it When installing the new oil filter element wipe the filter gaskets sealing surface on the engine block free of oil and apply a thin coat of clean engine oil to the rubber gasket on the new oil filter Screw the filter onto the threaded oil filter stub and tighten the filter firmly by hand NOTE Use genuine UNIVERSAL oil filters generic filters are nol recommended REFILL THE DlL SUMP Add fresh oil through the filler cap After refilling run the engine for a few moments while checking the engines oil pressure Make sure there is no leakage around the new oil filter or from the oil drain system and then stop the engine Then check the quantity of oil with the

housing over impeller 11 Install the three hex screws and tighten 15 12 Mount the pump to the engine taking care thai the end seal and gasket are in place Do not tighten the pump mounting screws just finger tight 13 Rcasemhlc the hose connections and open the raw water intake 14 Start the engine in idle this will allow the pump to align itself with its drive shaft 15 Stop the engine and tighten the pump assembly mount255ing screws 16 Start and run the engine check for leaks and check for a norrnal operating temperature NOTE Should a failure occur with the pumps internal parts seals and bearingsit may be more cost efficient to purchase a new pump The price of individual parts would almost match the price of a new pump Heat Exchanger The heat exchanger is a copper tUhe which encloses a num255ber of small copper tubes Raw water is pumped through the small copper tubes and the freshwater coolant from the engine is circulated around the copper tubes The raw water removes heat from the freshwater coolant To keep the heat exchanger operating efficiently it should be removed from the engine every 1000 hours to be thoroughly cleaned and pressure tested HEAT EXCHANGER ORING Zinc Anode CLEAR OUT DEBRIS DRAIN POOR ZINC ANODE i A zinc anode or pencil is located in the raw water cooling cir255cuit within the heat exchanger The purpose of the zinc anode is to sacrifice itself to electrolysis action taking place in the raw water cooling circuit therehy reducing the effects of on other components of the system The condition of the zinc anode should be checked monthly and the anode cleaned or replaced a required Spare anodes should he car255ried onboard The area in the exchanger where the anode is located should periodically he cleaned of anode dehris ENGINE COOLING CIRCUIT THERMOSTAT A thermostat located ncar the manifold at the front of the engine controls the coolant temperature as it continuously flows through the closed cooling circuit When the engine is first started the closed thermostat prevents coolant from flow255ing some coolant is bypassed through a hole in the thermo255stat to prevent the exhaust manifold from overheatingAs the engine warms up the thermostat gradually opens The thermostat is accessible and can be checked cleaned or replaced easily Carry a spare thermostat and gasket THERMOSTAT GASKET i THERMOSTAT HOUSING To Replace the Thermostat SEAL Remove the two cap screws and disassemble as illustrated When assembling the new thermostat and gasket put a thin coat of sealant on both sides of the gasket before pressing in place Run the engine and check for normal temperatures and that there are no leaks at the thermostat housing 14 RAW WATER COOLING CIRCUIT The raw water flow is created by a positive displacement impeller pump This pump draws water directly from the ocean lake or river from a throughhull opening through a hose to the water strainer The raw water passes from the strainer through the pump to a heat exchanger through the heat exchanger tubeswhere it cools the engines circulating fresh water coolant The raw water is then discharged into the water injected exhaust elbow mixing with and cooling the exhaust gasses This mixture of exhaust gas and raw water is driven through the stern tuhe and overboard Raw Water Pump TIle raw water pump is a selfpriming rotary pump with a nonferrous housing and a neoprene impeller The impeller has flexible vanes which wipe against a curved cam plate within the impeller housing producing the pumping action On no account should this pump be run dry as water acts as a lubricam for the impeller There should always be a spare impeller and impeller cover gasket aboard an impeller kitRaw water pump impeller failures occur when lubricant raw wateris not present during engine operation Such failures are not warrantable and operators are cautioned to make sure raw water flow is present at startup RAW WATER PUMP WEAR PLATE HOUSING AdobeUCSand add SCHEDULE NOTE

Use fuel that meets the requirements or specification of Class 2D ASTMand has a cetane rating of 45 or better Care Of The Fuel Supply Use only clean diesel fuel The clearance of the components in your fuel injection pump is very critical invisible dirt tides which might pass through the filter can damage these finely finished parts It is important to buy clean fuel and keep it clean The best fuel can be rendered unsatisfactory by careless handling or improper storage facilities To assure that the fuel going into the tank for your engines daily use is clean and pure the following practice is advisable Purchase a wellknown brand of fuel Install and regularly service a good filterwater separator between the fuel tank and the engine Raycor 500 FG or 900 FG is a good example of such a filter ENGINE OIL Use a heavy duty engine oil with an API classification of CF or CG4 or better Change the engine oil after an initial 50 hours of breakin operation and every 200 hours of operation thereafter For recommended oil viscosity see the following chart Operating Temperature Oil Viscosity Above 68F 2DCSAE 30 or 1 OW3D 41 68F 52DCSAE 20 or 1DW3D Below 41F 5CSAE 1DW3D A CAUTION 00 not allow two or more brands of engine oil to mix Each brand contains its own additives additives of different brands could react in the mixture to produce properties harmful to your engine 6 ENGINE COOLANT UNNERSAL recommends a mixture of 50 antifreeze and 50 distilled water Distilled water is free from the chemi255cals that can corrode internal engine surfaces The antifreeze performs double duty It allows the engine to run at proper temperatures by transferring heat away from the engine to the coolant and lubricates and protects the cooling circuit from rust and corrosion Look for a good quality antifreeze that contains Supplemental Cooling Additives SCAsthat keep the antifreeze chemically balanced crucial to long term protection The distilled water and antifreeze should be premixed before being poured into the cooling circuit NOTE Look for the flew IOllR lalfinf antifreeze that is nol1267 available Antifreeze mixtures will protect against an unexpected freeze and they are beneficial to the engines cooling system They retard rust and add to the life of the circulating pump seal ANTIFREEZE PROTECTION Antifreeze concen1ration Freezing Temperature 23 WF 5CCOOLANT RECOVERY

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
