When I took the rear axle apart, sure enough there was a babbit thrust washer between the steel washers, and it was crumbling. I am thankful for all the warnings I have read over and over again on this forum about the danger. My question is when I install the new bronze thrust washer, should I replace the steel washers also? They are slightly scuffed, should they have a polished finish? Or are the scratches from the babbit alright to reuse? Thanks again, Ed S.
You could polish them with sandpaper to avoid needing to buy more. They should be shiny and smooth.
Check the pins that keeps the steel washers from turning - they're frequently damaged and needs to be pulled and replaced. Easiest way to pull a damaged location pin is probably to drill a hole in the middle, screw down a sheet metal screw tight in the hole and pull everything out with a crowbar. If the sheet metal screw won't hold, thread the hole and use a machine screw instead.
Ed, I hope you're using the MTFCA axle book. I've found it a big help.
I am ordering the book with my parts, Thanks
The book covers this (I think, haven't read it in a while), but you will have to fit the new washers to your rear axle, they will probably be too thick. (this is good, it's the way things are, too thin would be a problem)
Roger, I checked the pins and 5 of the 6 were gone.
Royce, thanks for the idea, I will sand them down.
When I was "adjusting" the thickness of my bronze thrust washer, I put three small nails into a piece of 2x10 that I had lying around, driven low enough that they didn't stick up above the surface of the washer. The nails fit inside the ID of the washer and kept if from moving around. Then, I used my orbital sander with a 60 grit pad to sand the washer. Worked great!
You could do the same to polish your steel washers, but use a finer grit wet-or-dry pad and a few drops of oil as a lubricant.
