4-speed conversion questions
I am in the middle of my 4-speed converson ('85 300cd), and have a few quick questions.
1. what size pilot bearing do I need for the drive shaft. 2. I found that the new manual trans is 6.5 inches shorter than the auto. Is there any reason I just can't get the front side of the drive shaft extended that much? 3. What do you guys use for fluid in the manual trans? 4. Might be a stupid question, but which part is the flexplate? I have seen it talked about in several threads, but want to make sure I get it right. Is it the same as the pressure plate? So far, I have tore everything down, and want to start putting things back together this weekend. I need to get all new bolts, clutch, etc.

You are doing this without access to a Factory Shop Manual ?
Redline MT fluid is used by many. |

The FSM is of no use in this conversion. You are in territory unacknowledged by the factory.
GO here: Auto -> manual conversion Most if not all will be revealed in that thread.

It will at least give the names of the items in question... and speaks about balancing...

How have you sorted the small pilot bearing issue?

I just heard of that last night cruising through the superturbodiesel forum. What exactly am I going to be doing? From what I have gathered , I am going to be taking a grinder to the outside ring to make it fit into the 300's engine.
And thanks a ton for that thread RLeo. I have been studying that one before getting started...I don't think I ever made it all the way through yet though....HAHA

Lengthening the front part of the driveshaft is the correct proceedure.

I know I have to lengthen the drive shaft to reach the new trans, is there something else I should be doing to it?

Rebalance both driveshafts as a unit.

Depending on where you found the transmission, you may need to modify or replace the linkages (3).
Coupes have a shorter wheelbase than the sedans. Wonder if there is a sedan driveshaft that would work? Jim

I think the difference is in the back part of the ds.

Rumors of some W116 drive shafts being the correct ones have surfaced before.

With Q#2, I have been told that the drive shaft place will want me to take a total length of the driveshaft needed. I found that the manual is 6.5" shorter than the auto...I wanted to know if that will work (extending the front side by 6.5") or if there is something I didn't think of, and need to measure what I need with the new trans in place.

I am planning on sending the whole shaft to the place in San Antonio that RLeo sent his to. Funny story actually, there is a driveshaft place here in Shreveport, LA...but they refuse to work on anything European. They seem to think that it is going to cost me around $800 to get it done.

Is a w123 240d 4spd conversion done the same way or are there differences from a 300d?
