Gents,
I have a '73 with AC installed on it ("factory"). I've dropped an engine before on a non-AC'ed '76, but not sure how this is supposed to work with the AC compressor.

It appears it has some pretty thick lines running to/from it that go to the front of the car (running out the outside of the long on passenger side).

Do these lines have to be disconnected in order to drop the engine? And if so, does that mean "opening" up the AC system and it would have to be recharged or something?

Sorry, this AC thing is throwing me off.

Thanks!

Pull the AC first, then drop the engine.

I don't think that compressor will fit for the engine drop - at least it did not on mine.

Is the AC even charged? I could give you a hand if you need it. Let me know.

disconnect the compressor from the mount not the a/c hoses; leave them connected in case there is still freon (or whatever) in the system

With mine there was no charge left in the system. Probably had not been for years.

Yep, that's one of the few things that still works great on the car

Chris, you any good at valve adjustments? I need to do the pushrod tube seals and a valve adjustment, but I've never done one. Would love a knowledgeable person to show me the ropes!

Since the A/C still works ... do not disconnect the lines ... try to disconnect the compressor from the engine as stated.

1.) It's illegal to blow the charge to the atmosphere.

2.) If it hasn't been converted, it's R12 which you won't find anywhere anymore.

3.) Once you open up the system, you will have to flush the system to convert to R134A (which is also being outlawed) and change the filter / drier before charging the system again = $$$$

either hang the compressor somehow with some wire or place a milkcrate or something under it for it to sit on while the engine is out.

Engine removal is not necessary for push rod tube seal replacement.

To remove the engine with AC:

1: REmove the battery.

2: Unbolt the compressor and set it in the battery tray.

3: drop engine as you would a non AC car.



Simple........

I've got a spare set of pushrods tube seals if you need them. They're not bad to change out with the engine in the car. Done it several times over the years. Let me know if you need a hand.
