345 Engine removal

I need help with directions to remove the engine from my 1986 345 Airstream. I have a good shop to help rebuild it but although they work on Motor homes all the time they arenít so sure they want to take this on.

I will be able to tell you in a week or so. I found a little shop in Florida that specializes in RV engine replacement that is confident they can do the work. Judging by the number of V8 GM cars in his shop I’m confident he knows the engine.

You can read about my swap here: http://www.airforums.com/forums/f311...-a-140290.html

I took mine out with the heads on it. I removed the carb, exhaust manifolds - and should have removed the distributor. You need an engine lift plate that bolts to the intake manifold in place of the carb. I had to bolt the arm of my engine hoist directly to lift plate with no chain to get enough clearance. It is a tight fit, but it will come out. I had to jack up the front of the motorhome a little to get the angle right for the motor to come out.

Hey,
Engine removal is easy. At 61 , it's not as fun as then, but we know tricks ,we didn't t know then.
Remove heads
Drop exhaust manifolds
Remove starter, suspend from frame with bunge cord
Remove clutch fan assembly and alt and power steering pump
Obviously the radiator has to come out
Remove the lower fan belt pulley from the harmonic balancer
Disconnect torque converter from flex plate.
Your engine hoist needs to be a short vertical beam. They make them, and you have to ask them, how tall is the vertical boom on the hoist. It should be about 4 feet. A regular engine hoist boom will be about 5.5 feet tall that will not work. Your horizontal boom needs to go in to the engine compartment, almost level. Get the hook as close to the block as possible to the block.
Lift out motor, you will have to tip the front of the motor up to clear the front subframe.
It's a tight squeeze, but it lol come out I reinstalled my motor with the heads on, it was no big deal, but it's easier weight wise with the heads off. Good luck DJ
