front seal transmission leak
 

I have a slow leak in my front seal on my 190E. I am planning to get this fixed and it is quite involved according to my MB mechanic. What else should I do to the engine when this work is being done so that I don't have to pay extra labor later.

Thanks.

Have your tech check the rear crankshaft seal and cover for leaks while the trans is out.

Check the front clutchs as well, I've seen these wear and the k2 apply piston hit the front drum, sounds like the tranny is about to explode when backing up.

Thanks!
 

Anymore advice...I am scheduled to do this next week. I have a good mechanic but I just want to make sure since he will have my car for 1-2 days to remove the transmission.

Depending on the year of your 190E, there is a potential catastrophic failure of the reverse clutch. Repair involves the addition of a plastic piece to prevent the failure. If your car is one of the affected models *and* your tech has not apprized you of this already, this would indicate non-familiarity with service bulletins and factory material. Consequently, I would be concerned about them doing this level of job.

Depending on your mileage and the driving history of the car, it is not really *that* much more in labor to do the rebuild, considering the tranny has to be R&R'd already -- that's a decision that you would have to make.

Also, I would want to be certain that the latest B2 piston was installed in the car along with the "T" seal *and* that the piston was adjusted to the low side of spec (as recommended by MB).

Similarly, I would put the newer automatically adjusting B1 piston in the car.

If the rear seal needs replacement, make sure that the oversize seal gets put in if needed. [I would replace it on principle, anyway, since you are right around the corner from it.]

I have a 1993 190E with 200K on it. Runs well still.
