Rebuilding A KM Washer
Hi Ethan, Great progress, You may want to change the oil but there may be several even important things that you should be doing if you want to possibly get upwards of another 20 years use out of this washer.
My Friend Smitty got us around 4 feet of the thin wall SS tubing from a supplier in NJ, I will talk to him shortly and see if he can figure out where it came from, I would like to get some more myself as I have at least another dozen BD WP-KM washers that I want to rebuild in the future as well as rebuilding some for other folks in the group. You would be much better off with SS tubing, the orignal center post was heavily plated to prevent rust, the problem with just painting it is if you get even a tiny gap in the paint it may rust pretty fast. The other way we have talked about preserving these old center posts was to cover them with a vinyl-plastic type sheath. My vacuum cleaner butty Jason has said that it might be possible to get heat shrink tubing large enough to cover a center post and shrink it in place over the center post old or new to protect it from water. I will ask him about this as well when I see him a little later.
There is no drain plug on the transmission for oil changing purposes, I can tell you how to check the oil quantity and quality so you can determine if it is really necessary.
If you send me an Email with your phone# and best time to call I can describe in much better detail, John L.
