Engine Removal Question

I just became a proud owner of a 1992 300D. I love it! The only problem is the motor has an issue and I have to pull the motor. Can I pull the motor without also pulling the transmissions? I can not unbolt the torque converter because I cant turn the motor over. If anyone has any insight on this I would love to hear. Thanks

Pulling the engine with the TC still installed, may possibly distort the front pump on the transmission. If I had to separate the engine and transmission with the TC installed, I'd want to do this with both out of the car. When doing this in the car, the engine needs to be pulled at an angle, which will lead to the tweaking of the trans pump.

The best advice I can give is disconnect the flex disc @ the transmission and pull the whole engine & trans as an assembly with a cherrypicker.

Yea I think I will just pull the two together. A few more bolts and wire but I think it might help with the chance of creating more work down the the line. Also with the tranny out I can give it a good bath!


Do you think I should pull the oil cooler lines off of the housing our pull the entire oil cooler out with the motor?

Disconnect the trans oil cooler lines just ahead of the crankshaft and leave the rest.

Replace the flex trans cooler lines if they look old or oil soaked.

With the engine out, be sure to replace both engine mounts and the trans mount. You'll never have easier access.

OK cool. But what about the engine oil cooler lines that come off of the filter housing.

Just unscrew them at the filter housing and don't forget to unbolt the supporting bracket under the injection pump. Are you pulling the AC compressor too, or disconnecting the manifold?

OK. I just unbolted it from the motor and pulled to the side just like the power steering pump. I also just pulled the ALT. Off and straped it the core support. Does anyone know of a great place to get a FSM for my 92 300d because I will need torque specs and things like that?

The FSM is linked in the DIY sticky at the top of the main 124 page. Everything you need is in there.
