To replace worn hub bearings1 Remove the blades Two screws per blade on Mark I machines and four screws per blade on Mark II machines Remove the side
cover plate 910 series or slide nacelle back 913 and remove wires from the choke and from the rectifier Machines fitted with twin rectifiers remove
wires from the rectifiers Make careful note of which wire goes where for reassembly Slacken the two shaft locknuts and screws and slide the hub out of
the windshaft support casting Remove the six screws joining the hub halves together Insert two of these screws in the back of the hub 910 series or

bearings remove all the loctite deposits from the shaft and bearings This is most important to allow the halves to be joined properly Use Loctite 648
to bond the new bearings onto the shaft and into the hub halves When reassembling it is essential the indents on the mating face of each hub half line
up with each other When the hub is apart care should be taken to ensure that no steel or magnetic particles are picked up by the magnet It is also
essential to make sure that the magnets are clean before reassembly Once assembled allow at least one hour for the Loctite to harden before turning
the shaft Please allow 24 hours before the wind offering hubs towards each other they will be attracted together by a large magnetic force capable

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
