Tips&tricks to remove engine+transmission?

[jnes]

I'm about to pull of engine to overhaul it and clean the engine bay. This is the part of the bigger restauration job.. I have checked FSM regarding the engine removal. I'm just wondering how tight is the space to take it engine+transmission at same time?

Or would it be more feasible to pull out tranny first and then take out the engine?

Any tips from thos who have pulled m119 engine out?

Thanks!

Yes its possible.
Engine and tranny the same time.
I “killed” one hundred birds with this type of maintenance.
All, hoses, plastic pieces, gaskets and seals were replaced, other parts like ETA etc etc
I changed parts that were not really needed to be changed.

Thanks, any idea what is the weight of the engine+tranny?

I've read somewhere that the engine might be +/- 250 kg depending on equipment mounted, and complete transmission around 80 kg. It gives at least an estimate.

I've found it easier to remove the transmission first. If you do so, keep in mind the engine may tip forward when the transmission is removed, be prepared to support it. Then pull the engine straight up & out. This can be done by 1 person. It's FAR easier if you have a vehicle lift, and a tall transmission jack. If no bolts are seized (particularly on the exhaust), both engine & transmission can be removed by 1 person in less than 8 hours, with a lift. Might take longer without a lift.

Top Gear Top Tip: Remove the 2 upper transmission bellhousing bolts from above, not from below. There's just enough space to fit a breaker bar from above, and it's waaaay easier than using a bunch of extensions and universal/wobble joints from below. You'll need to remove the throttle linkage at the back of the intake manifold, and the plastic pieces across the rear of the firewall also.


If removing the engine+transmission together, keep in mind that you need a fairly extreme angle to clear everything. This requires an engine hoist that will lift quite far into the air, and also an engine tilt tool / load leveler. And, this would be much harder to do with only 1 person, without the 350kg+ assembly smacking into delicate components, scraping/denting stuff...

Have fun!

How the factory did it:

Here's another factory image.

Thanks, Arnt! That's what I was trying to find. Note how high the lift point is, and how angled the powertrain needs to be. This is why I remove the transmission separately...

I like the older techs protecting the car but using bare hands. Other pics...same.

We don't need no stinkin gloves.

Do I need some special adapter/tool as described in FSM for taking transmission out, our is there a risk that I make some damage to transmission if using just normal transmission holder, like below?



I was thinking to secure transmission from falling by using some straps..

Thanks!

I did the job a couple of times, with a proper engine hoist and load leveler. Same the factory did. It's a tight fit but with the right equipment and some experience it's done quite quickly.
Actually quite satisfying to see that massive thing diving into its position.
Much easer it would have been if the 036 would have got a removable upper radiator bridge as the W201 2.6es

Best to use the Wilbaer load leveler which is capable of quite steep tilting angles

I guess the rear end of the transmission will come down a bit, how much ground clearance is necessary to have underneath car?

 

[Rouven036]

Like about 25/30cm, usually having the car on a 2 post hoist with the wheels touching the ground. In the end enough that the engine crane legs go under the car without hitting. It

I've never attempted this with the bracket shown above (on an AC Hydraulics VL3, VL6, or VL10 - right?). AC makes a sweet saddle (click here) for those transmission jacks, with integrated straps and a rubber base, but it isn't cheap.

I was thinking to secure transmission from falling by using some straps..

DEFINITELY secure the transmission with straps and/or chains! The rear will angle downward when removing, and once removed the front end is heavier than the rear and it will want to tip forward. Be careful.

Ok, finally managed to take out the engine+tranny. I pulled transmission out before lifting the engine. Maybe it was right time since the lower wiring harness is cracked and brittle, also motor mounts were cracked..

Btw, what is the part number for the hook which will be installed above the thermostat housing?
I removed the housing cover and insert lifting hook to the smallest bolt.

My transmission bracket is homemade and quite basic but worked fine
