The first thing I did was to lubricate all the threads on
the tool to make sure they operated smoothly with no
galling.
Then I opened the jaws of the puller and slipped it around
the first bearing.
I then tighten the nuts by hand until they are snug and
even.
I use a wrench, not a impact gun as you can't feel as much
with the impact gun and you could damage the tool or the
crank shaft.
I tighten it so that the two halves are snug but not to the
point where the inner part of the jaws are touching the
bearing journal.
Next, I install the bolts that hold the cross piece.
I only install them finger tight but I make sure they are
nearly bottom out.
Then I install the cross piece and tighten the long bolt
finger tight so that it is snug against the end of the
shaft.
If your crank has an internal thread on the end where the
long bolt is pressing I recommend that you put a bolt in the
end of the crank to protect the threads from damage.
