Subject: [6pack] What size thrust washers do I need?
I measured my crankshaft end float the other day and found it to be just
under .012". I would like to get the end float closer to .005" so I
dropped the pan, took off the rear main bearing cap and removed the thrust
washers. What I found was one marked "STD" and measured at .090" which
showed a lot of wear and the other marked "+030" that measured .122" and
showed very little wear. I believe that STD should be .092" ?
I have read online that the front washer should not change size because it
gets very little wear and you don't want to move the crankshaft out of
place.
I have also been told that both the washers should be the same size so to
center the crankshaft which also makes sense. TRF sells sets of thrust
washers at STD, +.005", +.015" and +.030" which I believe both washers in
set are the same size.
Now I would like to reduce my end play from just under .012" to just over
.005" which means I have to add .006" to my thrust washers. In order to do
that I need a total of .218" with both thrust washers measured together. I
like the idea of using Scott Helms's solid bronze thrust washer. I could
have a .096" made and my use my .122" or if the front should not change I
could use a STD .092" and make a .0126" or if the crankshaft should be
centered, have two .109" made, all which would equal .218"
Oh, one more thing, TRF's list at $6.95 a set and Scott's are $20 each and
are probably worth every penny of it. If you still follow me, any comments
as to which way to go?
TIA
