Detensioning the A/C Compressor

[psyshrike]

Howdy,

To remove my belts, I have to detension the A/C compressor. Do I have
to disconnect the A/C hoses to do this? What am I missing?

I have loosened the tensioner lock nut, and loosened the tensioner,
but the compressor only moves about a quarter inch. I tried leveraging
it with a 2x4 between it and the frame, but the engine mounts just
absorb the leverage.

Somebody _please_ tell me there is a way to do this without taking
apart
the A/C system.

-Thanks in Advance!
-Matt.

Assuming you have a B230 with the compressor low on the left side of the
engine, there's a second nut that need to be loosened to allow the
compressor to move, on the rear of the compressor. You need a 6" wobble
extension or universal joint to access this nut from in front of the
compressor.

Don't forget to loosen the second tensioner on the compressor. It is toward
the rear of the compressor on a B230FT engine.

I'm assuming this is an older 240 or 760T? If so then you have a silly split
pully on the crankshaft, remove the 6 bolts on the face and it comes apart,
keep track of how many shims are in front and behind the pully half.

Thanks!

That aught to do it.
