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. |

Re: Inserted B motor thrust washer help needed.
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.

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. |
