The accessory bracket stays. No problem.

You have to go into the wheelwell to disconnect the bracket to the tailshaft housing, the oil pressure sender, the knock sensor, and the T2V connector to the PS pump.

No bracket needs to be removed from the AC. 3 bolts total. Look at it again in a fresh light.

You SHOULD be able to get the backwards bolt out with the rear manifold removed. If you can't get enough leverage to remove it that way, you can see it to guide Victor in with a long set of extensions and a big breaker bar.

Mine rotated over 90 degrees with a half-inch breaker bar (36" long) before it broke loose. Mostly because of the stacked extensions.

Can the tail shaft bracket be removed now without supporting the engine, as long as I leave the other supports intact :?:
I think I can get in there without taking off the shield unless you know a good reason why not.

In a couple of months you're going to have to help with bolt torques but a 36" bar What torque are the trani to engine bolts. :?:

I just checked again and the Compressor is bolted to a plate that is sandwiched between the block and the passenger side motor mount bracket.with two large bolts. What am I missing :?:

The bracket stays on the motor. Two front bolts and a rear bolt will allow you to rotate the compressor out of the way.

I did it all from underneath.

Getting it lined back up and that rear bolt back in is a little tricky. Helps to have someone above while you work below to help align the holes. The rear will be very easy to strip out (talking reassembly here)

Yes, it'* 15 mm and very tight. Got it off.
The only shallow 15 mm I had is one I use for the SC belt tensioner.

Great advice guys.......keep it coming.

This is the first time I've done work like this without a manual.

Now I still can't see the two front bolts for the Compressor. :?

Where are they? Underneath? But the frame runs under it......how to access??

Would it not make sense to install the front bolts first so alignment with the rear is simpler :?:

I plan to remove the rear bolt first and the front ones last before hoisting the engine out.

So you're all saying I should not need to support the engine if I remove the rear mount, as long as the side and trani mounts are left intact :?:

Paul, I'm sorry that I wasn't thinking this morning.

I have a shop manual for the '94 that you can borrow if you want.

Hopefully weather will permit me to go up to Campbell River tomorrow to pick up my plane, I could drop off the manual at Powell River if you want to borrow it.

That would be fantastic John

But don't take any chances with the weather.

The weather sure changed in a hurry today.......from clear and sunny as far as the eye can see, with no wind.....to cloudy, rain, wind and snow, all within a few short hours.

Glad you two made it home safe.

Took off the exhaust myself this morning.....both front and rear manifolds.
Only the front one had a crack on one of the welds.

I still haven't spotted the rear support. Does it mount to the trani?

The AC compressor is next. Got one of the front bolts and see the other one. They are both backwards....that'* what confused me......now where is the last one?

So you're all saying I should not need to support the engine if I remove the rear mount, as long as the side and trani mounts are left intact ?
