355 A/C compressor, engine out

    So, I’m in the middle of dropping the engine from my 355...

    The previous times I dropped the engine I took the car to have the R134 sucked out before starting work so I could just disconnect the lines to the A/C compressor and drop the whole subframe.

    I read somewhere on here that it’s possible to unbolt the compressor and there’s enough clearance to drop the engine, saving the need to remove the refrigerant, so now that I’ve (finally) bought a lift I thought I’d try that method.

    I’ve unbolted the compressor, it’s completely free, but I cannot see how there is enough clearance when I start to lift the body away from the subframe. It will snag for sure.

    So my question is: has anybody here dropped the engine out of the 355 but leaving the compressor hooked up to the hoses?

    Any tips or tricks? Should I unbolt the engine mount and lift the engine or is there another way?

    Any thoughts gratefully received.

    Bob.

    Hindsight is a marvellous thing — that’s what I should have done and will do next time, but now the car is on the lift at my home, no way to take it anywhere and we are shielding, so we don’t want any mobile guy to come over right now, so I have to deal with it.

    I refuse to let the gas into the atmosphere.

    So, back to the original question... I know it’s been done, so please chime in.

    I'm afraid I have no knowledge on the 355 engine drop, but for what it's worth ( probably nothing) I've dropped my 348 engine twice with the A/C compressor lines hooked up. You have to fiddle around with it a bit, and as I recall on the 348 there is a large pipe carrying oil that has a ring bolt into the right front side of the block that gets in the way, so that has to be disconnected, and then you're good to go. One of the fuel filters is in that general area so maybe that needs to come out too, but I think it's just remove the compressor bracket, disconnect that oil pipe and move the compressor as needed as the sub frame comes down.. You need a bunch of string or zip ties to support the compressor once the engine is out.

    I'll echo "pnicholasen'. That's the way one can do it on a 348! My next major will have it sucked dry... just way too much fiddling! I'm sure it took me 2 hours to screw around, twisting and rotating! As far as a 355, no idea as well, but I'm sure it would be a little different... maybe not even possible. So... hire a mobile guy to suck it out, and thank yourself for not adding to the planet's problems

    I am doing an engine out right now, they just let compressor hang in the lines, no problem at all.

    Hi, is this on a 355? The cradle drops out and the mounting brackets for the compressor can pass by?

    tack så mycket.

    Yes it's a F355.

    I don't know exactly how they did it but they didn't disconnect the lines and let the compressor hang, it's a well known Ferrari independent who has down many engine out jobs.

    Look at the pic below.

    Great! I’m nearly ready to lift the body off the motor, tomorrow or Monday work commitments permitting. Thanks a lot for the photo, I’m feeling more confident about the compressor now.

    Well, that photo shows how useless my comments were regarding my 348 because apparently the compressor is on the port side in the 355 instead of the starboard like the 348.
    Just remember even if it takes an hour of figuring out how to wiggle it free, it's still way faster than pulling your front trunk liner out to access the A/C ports, taking it someplace to drain the refrigerant, then taking it back to refill it ( hopefully correctly) and refit the trunk liner.

    Success!

    It was actually a lot easier than I thought it would be. Lift the car & rotate the compressor 90 degrees.

    Depending how fiddly it is to reassemble this might become my new standard method. As PNICHOLASEN says, it’s a lot less hassle than going to to get the freon pulled out.

    I’ll report back on how tricky it is (or not) going back in.

    Obviously no older English cars reside there.

    not right now, and you're dead right, those old British cars with scroll "seals" on the front crank leak no matter what.
