removing engine, few ?s
After deciding my engine wasn't worth fixing, I started getting it ready to come out today. Just about done, but I have a few questions I wanted to ask you guys before I went on. First, since I dont have another engine to put in yet , is it okay to let the tranny sit with no fluid in it or will it start to rust? What about over winter? Second, my truck has air conditioning that I have no use for and I would like to remove it all but the manual says its dangerous and should be discharged first. How do I do that? I know for a fact it hasn't been used for at least 5 yrs, maybe more. Dont know anything about air cond. systems so all info about removal is appreciated.

Why would your tranny be dry? There is no reason to drain it to remove the engine. If you remove the torque converter be sure to keep fluid in it and stick a CLEAN paper towel on the output shaft of it or wrap it in a plastic bag. Your A/C should be drained by a licensed professional. Should not cost to much considering your are giving him free freon.

You can leave the tranny as is, but when you go to put it back together later, you need to pull the torque convertor out and replace the seal. The weight of the convertor will deform the seal after awhile and it's cheap insurance to replace the seal anyway. You are kind of stuck with the ac. You can't take it to the shop to get it drained I guess, because it's not running, and it's illegal to drain it into the atmosphere. I would wait till later, after you get it going again, and get it drained then.

If it were me I would keep the A/C on there. Maybe after you get your new motor, you might get a wild hair and get the A/C working. At nothing nicer than cruising in a 70's ford truck w/ the A/C blowing. But then again I'm in Alabama so A/C is almost a must.

Does the A/C still have a charge in it? It might not. I bet it doesn't. You can check by putting an A/C pressure gauge on the system - or by trying to let a little squirt of freon out of the system.
If it still has a charge, it is possible to remove the whole system as a single unit leaving it sealed. You might also be able to unbolt the compressor from the engine, and pull the engine leaving the A/C in the truck.
If there is no charge in it, you can pull it apart to your hearts content. Actually, if possible, leave the system assembled. This will prevent moisture from getting in and mucking things up for the time that you decide to use it.
