Hiya,
Just a quick update. Got the motor up on a stand for disassembly last night...
A couple of observations, the machine shop I'll be taking the stuff to says
I *must* have the Cam bearings removed before going into the hot tank, I'm
not sure if this is a way of securing my business <G> for both the cleaning
and machining process but what the heck. Anyone? Can I do this without the
special tool shown in the Service Manual? Another thing I found, there is a
3/4" bolt just below the oil cooler outlet on the back of the block. I took
this off and found so much thick, carbon-ish like gunk in there. Is this the
end of the waterway or something? I couldn't clear it all out, hope the hot
tank will.
Lastly, Woodruff keys (what a name!) - How on earth do they come out? <G>
Mine seem to be stuck fast. My motor is an 18GJ - Californian version of a
GH.
Cheers,
Neil.
Neil -
The machine shops I've been to just take the block as I've stripped it, hot
tank it, do the machine work, and when I get it back the new cam bearings I
bought are installed. It is true that hot tanking ruins cam bearings so
they must be replaced. I've never heard of a shop requiring the owner to
remove the old ones first. I couldn't get the Woodruff keys out either -
so I left 'em in. No harm since in all three cases, the cam timed
perfectly without resorting to offset keys (can't remember - would one put
the offset key on the crank or the cam?).
