Re: [T3] stuck heads...


Thanks for the suggestions.... they came off eventually with a little
persuasion ;-).  Then I discovered that the pistons were seized in the
cylinders....  A torch, and some special chemicals that instantly
dissolves rust and.... nothing.  I took a mallet and smashed one of the
pistons in.  The cen\Ï(d in and fell in the case, but the outer rim
of the piston was still seized into the cylinder wall.  I had to smash
the cylinders apart to free them form the pistons.  Bear in mind the
crank was seized solid and bugged not an inch during all of the heat and
pounding.

Upon closer inspection it became clear to me why they were seized...
sugar.  The sad fate of this old girl was at long last discovered.  This
was confirmed by our service manager too who used to be a diesel
mechanic before he became a Harley guru.

Heck, I had to cut through the wrist pins, as I could not get them to
budge either.  After removing the pistons, heads and jugs (not in that
order ;-) I sprayed the innards with some good rust eating chemicals,
within minutes the crank freely turned.

The rest of this evening was spent removing the cooling shroud, fan and
oil breather.

Total time: 3 hr..

Tomorrow we'll split the case.

Tuesday, sandblasting begins.

By the way, blasting that case is ok, isn't it?  Any precautions?  or
can I basically blast any surface. (silicone beads -- all we have)

Thanks for all the input....

Charlie
