How to remove engine and trans from W107

Post by CraigB » Tue 16 Sep, 2014 9:41 pm

I did do a search but didn't come up with anything. A bit lost in cars at the moment and a long story why but decided to pull the motor from Lurch and see where the motor is at. I think one of the drivers is my cousin and my main 'car mentor' from a young age hasn't been doing too well and has had a kidney out amongst other things. Went to visit him and got talking engines. He did his apprenticeship at Adelaide Engine Service and spent many years rebuilding benz engines. With Lurch being a nice original car my first preference i reckon is to see if I can't rebuild the matching number 350, and if that fails then it opens up the options and maybe becomes a 560SLC if i can find a sump.

So first question is any tips on removing the engine and trans. I think Joe said the trans is good, but looks like some minor leaks so might as well get it out and redo all the seals. I have this recollection someone saying motor and trans have to come out separately? Any tips re easier if car on stands, over a pit etc etc. Got manifolds off today with only one stud breaking so that's a good sign!

I've only ever pulled them out separate to the trans. too much weight. But shouldn't be that hard without the d-jet inlet manifold in the valley - that might make all the difference?

I still think it will be a bit of a PITA but I've been wrong before and happy to be shown an easier way to get it out. Not sure the 560 would be as simple for some reason....

I pull them out with the trans because one of my pet hates is fighting with stubborn bell housing bolts.The engines weigh a ton but the trans isn't that bad.

i think you could also undo the gear box mount and the front end/steering box and lift the body off the running geaqr the same way i do pontons and W110/W111 & W108/109's.

Thanks Ron, I reckon you would have pulled more of these than most so i will do it exactly as you have!

Had a few minutes this morning and curiosity got the better of me and i pulled the heads. There was water and reasonably heavy rust in the bores. I will measure one of the good bores and see if it has been bored before . My cousin has equipment to bore and even sleeve blocks (and one of the few people left who can white metal your vintage rods!) so i will strip the pistons out (he says hopefully!) and get the block to him and see what he says. I imagine not until a bore is run through it will it be clear how deep the rust is but is often not as bad as it looks. And it is a shame because there is no visible ring groove, which may mean it is already oversize - wait and see. I bet in all those 3.5 engine parts you were trying to get rid of there was a set of oversize pistons that would have fitted!! I am such a terrible hoarder but resisted adding to the list a pallet full of engines thinking i would never use them!
