Inserted B motor thrust washer help needed.
 

So I have a destroyed thrust washer in my b motor. I ordered a set of thrust washers from Mikes. Got them in today. Wrong size. I know there are some variations out there on this stuff, and here we are...

So it looks like thickness is correct. .25" What I removed was .2145, yeah that worn out but was not giving any issues.

The Id is good. 2.00 " and what I removed was 1.94
The OD is way out. 2.88 and what I removed was 2.59


Does anyone have a way to get the correct size. Or do I need to tear this motor down all the way and open the rear thrust surface cutout up to accept these washers?

I don't have a lathe or machine shop in my garage so I am a bit limited.

Any help is greatly appreciated.

Since you do not have access to a machine shop, a make-shift lapping table is likely your friend taking the 0.030" off. Just start a lapping process on a piece of glass or a known-flat surface, and begin working the thickness down rubbing it on oiled sandpaper. The OD can be sanded on a belt sander or even a grinder while continually checking to make sure it stays round. If you blue the edge with a Sharpie marker and then set your calipers to 0.138" and scribe the perimeter, that will give to a "sand to" line.

Thanks Brent, I did some machining with my bench grinder and belt sander. little bit at a time was key for sure.

Good meeting ya in Chickasha and thanks for the Dual intakes...

If anyone else ever comes across this. This is a example of a bench grinder, some precision file shaping and cutting oil grooves into the washer look like.

The above is the larger diameter OD that the places are selling stock now.

👍 oil grooves really help the thrust live when you got your foot on the clutch at a red light
