[xk] Crankshaft end float

XK
1

Guys,

I am trying to get the end float right. The original thrust washers give
end float of about .008". The Service Manual says it should be .004 to
.006. I tried replacement standard thrust washers that give me almost no end
float, certainly less than .004.

Should I re-use the original thrust washers or use the standard thrust
washers?

End float is important. I suggest “adjusting” the end float on the new
thrust washer with a little file work or compound and plate glass.

You have probably sorted out your problem, But, there are two sixes
of washer, use the two (new or old) that give you the correct end
float.–

It’s unlikely the thrust spread on your crankshaft got
smaller over the years, so I would put in the standard
washers. It takes a fair amount of pressure (not just
pulling the crank by hand) to determine the end float. Put
in the standard washers, and use a pry bar or long screw
driver to move the crank back and forth. I would guess the
end float will be .004’’ to .006’’. The new washers will ‘‘run
in’’, and give you a little more float.
