The lasts step is to replace the pulley and for this task an impact driver was used.
While this alternator did not require a full “rebuild“, and all it needed was bearings, taking it apart, cleaning it and inspecting the brushes, bearings etc. is never a bad idea.
With the front & rear bearings replaced, the internals cleaned, and the case bead blasted and put back together she is ready for another 2800 more hours.
While an alternator like this can survive for quite a long time charging a small bank, they will not survive charging massive house banks. The calls I normally get for alternators like this are EOL calls (end of life) because they have literally cooked themselves. Once they cook there is no sense in even repairing them and it is best to opt for a higher performance alternator and regulator system. When trying to charge massive banks not only will the alternator suffer but so will the batteries. Alternators like this reduce regulation voltage as alternator temperature increases. This winds up chronically undercharging large banks and we get stuck in a Catch 22..
TIP: If you want to paint the alternator case please do so before putting it back together. Only paint the exterior parts of the case so you don’t impact the ability of the aluminum to dissipate heat.
This is not a difficult job and most any local alternator shop should be able order you the parts you need. I got my front & rear bearings from a local auto bearing shop here in Maine for about $12.00..
If your alternator needs diodes, a regulator, stator or has other more serious issues I recommend finding a competent auto electric shop and have them complete those tasks.
Good luck & happy boating!
