increase a little in a newGenerally the time at which an engine should be overhauled engine until piston rings and valve seats have been broken inis determined by various conditions such as lowered engine Thereafter it decreases gradually with the progress of wearpower output decreased compression pressure and increased of these partsfuel and oil consumption The lowered engine power output When decrease of compression pressure reaches the repairis not necessarily due to trouble with the engine itself but is limit the engine must be caused by injector nozzle wear or injection pump The engine requires overhaul when oil consumption is highwear The decrease in compression pressure is caused by blowby evident and compression values are at minimum ormany factors It is therefore necessary to determine a cause below Engine compression should be 31 kgcm 441 psi ator causes on the basis of data produced by periodic 200 rpm The maximum difference between cylinders mustinspection and maintenance Oil analysis on a seasonal basis not exceed 10is a good means of monitoring engine internal wear Whencaused by worn cylinders or piston rings the following will occur 1 Before disassembly and cleaning carefully check for 1 Low engine power output defects which cannot be found after disassembly and 2 Increased fuel consumption cleaning 3 Increased oil consumption 2 Drain water fuel and oil before disassembly 4 Hard engine starting 3 Clean or wash the engine exterior 5 Noisy engine operation 4 Do not remove or disassemble the parts that require noThese symptoms often appear together Symptoms 2 and 4 disassemblycan result also from excessive fuel injection improper injec S Perform disassembly in a proper order using proper toolstion timing and wear of the injectors They are caused also Keep disassembled parts in order Apply oil when necesby defective electrical devices such as the battery alternator sary Take special care to keep the fuel system parts fromstarter and glow plugs Therefore it is desirable to judge the intrusion of dust and dirtoptimum engine overhaul time by the lowered compression 6 Parts must be restored to their respective components frompressure caused by worn cylinders and pistons plus increased which they were removed at disassembly This means that alloil consumption Satisfactory combustion is obtained only parts must be set aside separately in groups each marked forunder sufficient compression pressure If an engine lacks its component so that the same combination or set can becompression pressure incomplete combustion of fuel will reproduced at assemblytake place even if other parts of the engine are operating 7 Pay attention to marks on assemblies components andproperly To determine the period of engine overhaul it is parts for their positions or directions Put on marks ifimportant to measure the engine compression pressure regu necessary to aid assemblylarly At the same time the engine speed at which the measurement of compression pressure is made should be checked S Carefully check each part or component fore any sign ofbecause the compression pressure varies with engine rpm faulty condition during removal or cleaning The part willThe engine rpm can be measured at the front end of the tell you how it acted or what was abnormal about it morecrankshaft accurately during removal or cleaningNOTE To test engine compression see the ENGINE ALTERNATOR section of this manual When rebuilding the engine the alternator should be and inspected The housing can be wiped off with a solvent and the alternator terminal

of the solenoid assembly I for continuity as follows a Check the resistance of the solenoid pullin and holdin windings in series by measuring the resist ance between the motor terminal see Figure 9 and the solenoid case The resistance should be approxi mately 095 ohms for 12voIt starters and approxi mately175 ohms for 24voIt starters h An extremely high resistance reading indicates a break or fault in the winding continuity A very low resistance reading indicates a short or ground in the MOTOR winding circuit Either condition is cause for TERMINAL replacement of the solenoid assembly2

the driving force of the engine to produceAC output The copper and laminated iron in the exciter statorare responsible for the selfexciting feature of this generatorThe magnetic field produced causes an AC voltage to beinduced into the related excitor rotor windings during rotationDiodes located in the exciter rotor rectify this voltage to DCand supply it to the windings of the rotating field This createsan field which rotates through the windingsof the main stator inducing an AC voltage which is suppliedto a load An AC voltage is produced in the of the main stator and is in tum supplied to avoltage regulator The regulator produces a DC voltage to CIRCUITfurther excite the exciter stator windings enabling the to produce a rated AC output The voltage regulator SWITCHsenses AC voltage output and adjusts DC excitation to theexciter stator winding according to amperage load thegenerator is furnishing To maintain a constant voltage output OPERATION A CAUTION Prior to performing any

I do not sell or share any user data or anything else for that matter. The only personal information I save is in the site log which has a line for each page view which includes the IP address your browser sends in the header as well as which page you requested. I use this to block hackers and other bad actors. I do not use this raw data to create profiles on users. I periodically delete the log files.
If you are subject to CCPA, Google ads on this site will not be based on your past behavior so you will likely not see an ad for a lawn mower just because you looked for one at a big box website. I do not believe this site is subject to CCPA but I am doing what I can to follow the guidelines anyway.
The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. 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. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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 numerous 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.
