Who's Pulled A Few W123 Engine's?
Who's Pulled A Few W123 Engine's?
So, I'm in the middle of a engine swap on my family's wagon and I've been slacking (100+ degree heat here in the valley of the sun). Pretty much everything is disco'd except, the torque converter bolts, the drive shaft tensioning nut, drive shaft bolts, the trasmission cooler lines, shifter linkage, and mounting bolts. Any advice to make my life easier? My plan is too pull the engine and transmission out together and then pull the transmission off and move it to the new engine and then put it all back in minus SLS.
Don't forget about power steering lines, speedo cable/wire, oil pressure tube/wire,
pull the radiator and oil cooler to make it easy.
You will have to pull the motor almost straight up out of the engine bay, taking the front wheels off the car and lowering it will help tons.

For the oil line to the gauge off the back of the oil filter housing use a a good line wrench I have seen an 11mm and 12 mm used on the fitting. Its really easy to strip out and a new line is like $20-$40
It took me 30min to pull the 4spd transmission out of my 240d
We change the engine in my dads 83 300d with out pulling or disconnecting the auto transmission just unbolted it and the TC and pulled the engine forward 3 inches and lifted it out we had a jack and some boards under the transmission to hold it in place

Also check directly under the motor for a 3rd engine mount directly to the cross member, I don't think the 300s have them if I can remember, but its on the 240s, and is easy to overlook.

get some plastic and some zip ties, then each thing you unhook or uncover, like the intake, coolant ports, oil ports, ect, you can cover, and zip tie the cover snug. Worth it to prevent FOD, had a 10mm nut destroy an engine in my mercury once, was not fun.

Yes I have a load leveler and a engine hoist, should I take off the hood or just the grill? What makes it easier by jacking up the rear? I'm tempted to keep the transmission in there method and try and shoe horn it back in there. I already stuffed every hole with shop towels
Personally I do not like messing with a load leveler and with the tans intact. Just hard for me to maneuver, it seems I was always bumping something.
I like pulling the engine without the trans intact so the engine goes in and out straight up. I also like using good condition old seat belts, instead of chains to attach the motor to the hoist. It's easier to adjust forward or back then the use of chains.
It seems to me easier to separate and reattach the trans and motor together while in the car. You just need to drop the tail of the trans and reach over the top with a long extension and a swivel socket to get to the upper bell housing. Use the extension and swivel for the starter bolts. I remove the radiator, leave the fan on, leave the oil cooler intact to prevent a mess, set aside the power steering pump and put the hood in the upright service position. Pretty much pulls straight up.

07-31-2011, 04:52 PM #10I've pulled and installed a 617 almost a dozen times. Done both with the trans intact using a load leveler and with out the trans intact.

With the trans on its about 6" or so long and has to come out a 45 degree or sharper incline. You basically need an effective clearance of 3' or so under there. The more of an angle you have with the rear up the better chances of you getting it out. Personally I would only take eng in and out with trans on. Too much of a PITA for the top bolts on the trans.

It really is not bad, you just need the right set of tools and have the car jacked up high for better turning leverage on the breaker bar.
