Or try http://tinyurl.com/j6aurtu $3.66/10g, because
who needs a
full pound of lapping powder?

I've often wondered how this lapping powder would
work on say, a '66 GM 225 V-6 crankshaft. Use it
to fine tune the clearances all at once. Solvent clean
ofterward. Anyone try this? ;) phil k.

Wouldn't the abrasive just get embedded in the insert?
That's not good... sorry i posted the question. phil k.

Greetings Phil,
The yellow label stuff is for lapping soft metals in just the kind of
application you describe. I have lapped in many babbit bearings using
Timsaver lapping compound. Mix the stuff with oil according to the
instructions and apply through oil hole if the bearing has one or
apply to bearing shells and assemble the bearing. The abrasive will
not embed into the soft metal but will instead lap it. Conventional
lapping compound, like the Clover stuff, will embed in the softer
metal and lap the harder metal. Timesaver works opposite in that it
will not embed and will lap the softer metal.
