Replacing 4-Spd Manual Using Harbor Freight Transmission jack - Page 2 - PeachParts Mercedes-Benz Forum

my dad's little secret...
get a pair of longer bolts that thread into the block, cut off the heads, and cut a slot in it for a screwdriver to unscrew when done.
makes it a tad easier to align things when you don't have to hold up the transmission...

I have to file that one away... still have to replace my clutch this winter.

When I had the driveline shop replace the U-joint, it was balanced at that time, and hasn`t been taken apart since I installed it at that time.
with this trans swap Iam doing now, I just slid the shaft back w/o disconnecting it.

I don`t have a W124 fsm. I do have the Bently E-Class Owners Manual that I Picked up at a PNP for $5. some interesting stuff in it, but definately not a true FSM.

I lowered the rear, raised the front, lowred the whole thing etc.... with some washers to try to smooth this out. so only thing left is swap in this other trans. with the luck Iam having, probably worse than the one I pulled out.

Well today I removed the clutch to see what is up with the pilot bearing. there is was just laying there. guess it came out when the trans did. looked it over and looks like when I instaled it 20K miles ago. so put it back in the crank, buttoned the clutch up.

Raised the trans on the jack, got the shaft in the clutch hole, held onto the rear of the trans and got the jack out of the way. wiggled a little, and the trans went right in. Dang, wish i had noticed that pilot bearing early on yesterday. That is one thing I won`t forget to look at the next time.

Got all the bolts in and tightened down. the top 2 that I have read about being a problem to get to wern`t all that hard to reach.

The Slave cylinder was a problem, because removing the trans, the line hung up on the shift levers coming down and tweeked the metal line. so being bent some wouldn`t let the slave line up to get the 2 bolts in. fought it about 30min tweeking the line some, but no go. so with fear and trembling, I removed the line to the Slave, remembering the trouble bleeding the clutch doing the original swap.
Got a good bath from the Slave cylinder. with the line removed, and pushing in on the rod that pushes on the shift fork, it gets shoved into the slave. and where do you think the brake fluid goes then?

Bolted down the Slave, then fiddled with the line, and finally got it to thread in. sweet talked my wife to pump the clutch, and we bled and got it working again in a few minutes.

I ended up the day with getting the shift rods mounted. dang those little spring clips are difficult to get on. not a lot of room upin the tunnel or the shifter area, and it was getting hard to see as the sun was going down and looking like it is going to rain.
When I put them on last time, It didn`t seem to be all that hard, but I`ll be damned if they want to go on today.

Tomarrow this should be all wraped up and ready for the road

Any chance the flex disks are backwards? Who loves ya http://w124-zone.com/downloads/MB%20CD/W124/Index/Groups/41PropellerShaft.htm

Thanks for the 124 link.

Flex Discs are directional? I don`t see a difference from one side to the other.

ARRRRGH, it rained last night, 1:30am I get woke up with rain hitting the windows.

the car is on concrete, but I have my pieces of carpet spred out and tools, jacks,oil pan etc....
Didn`t last long, but drops were big. so Iam out running around putting things under the car with a flash light. sorry, no pictures

The w124 fsm seems to indicate that they are.

charmalu · #22 10-22-2010, 01:26 PM

I just went throught the 124 link and didn`t notice anything directional, doesn`t mean it is not there.

I did read something interesting that they have balancing nuts and washers for the flex disks. I don`t remember reading that in my W123 FSM.

They also list a soft rubber disc for the front and a hard rubber disk for the rear.

I think the flex disk might have been under transmission. I found the w124 fsm to be very enlightening. Does this describe the problem : https://docs.google.com/viewer?url=http://w124-zone.com/downloads/MB%2520CD/W124/Index/Resources/AF41.10-U-1200BG.pdf

I don`t get a booming or thumping noise as the site mentions. more of a rough sound like u-joint rumbling, or ?.................

When we are in Oregon, their roads are rough from all the studded tires and snow chains. so there is a rumble, roar noise in the cabin from the tires. this reminds me of the noise.

what ever it is, I`ll do some more tweeking of the cross mount with some spacers.

I got it all back together today, and went for a run for about 30 miles. seems to act the same with the different transmission. this trans is a little looser than to other one.

It`s been wet and misty rain all day off and on, so working under the car wasn`t too bad. but my carpet did get a little damp. had to put on some rain pants to stay somewhat dry.

I would have finished a lot sooner if that pilot bearing hadn`t come out, and I noticed it sooner, and I hadn`t bent the Slave cyl line a little droping the trans. that slowed me a little. next time the slave is being removed first and out of the way first.

Those little spring steel clips that hold the shift rods are a real pain to get on. must be a trick to getting them to slide on easier.

So the car is up and running for now, and next week it`s making a trip to Carson City, NV. running smooth or grinding, growling and vibrating.

Different trans same sound? GRRR! You replaced the center bearing of course?

charmalu · #29 10-24-2010, 11:40 PM

Yes, The center bearing was replaced the same time the U-Joint was replaced and balanced.

When this rain storm blows on by, Iam going to try lowering the trans X mount, or raise the trans rubber mount with spacers, trying to find the best sweet spot.
