I overhauled a two speed ABI 800 windlass this year. Some parts are available from ABI. I just did an internet
search but couldn't find their phone
number. However I did talk to ABI (search for ABI Precision Lighting) when I needed parts about 6 months ago.
If the bushings have no serious slop or free play they are probably OK. All the sealing is done with O-rings. I found O-rings at Shucks (our local mega chain auto parts store - try also Pep Boys, AutoZone, etc.) and at an industrial fastener and tool supply house (in the Seattle
area -- Tacoma Screw). Take the old O-rings to the store to match the sizes. O-rings are sized by the cross section diameter, the inside diameter, and the outside diameter. Be sure to get Buna-N or nitrile rubber. It is the oil
resistant polymer for this application.
If the bushings are sloppy and ABI can't replace them, you should be able to find a machinist to make new ones.
ABI provided me with new springs for the ratcheting gears in the windlass. If you install them make sure the springs pull in line with the slot in the gear
carrier. I had the springs perpendicular to the slot and that was my problem in my first post.
The windlass I overhauled hadn't been used in many years. I found that it had water
inside. I bought gasket
material for the plate on the bottom either from a NAPA auto parts store or from McMaster Carr on-line. I also bedded the gasket
in Permatex #2.
You can get replacement oil from the auto parts store as well. I think it took about 1 1/2 quarts of 80W-140 gear oil.
