D4D Engine/Tranny line-up

samedi 16 août 2014

Hello everyone,



I have problems with the line up of the Engine and Torque Converter. I bought this D4D Cat (serial # 22C407) and the previous owner ripped the 4 rubber "donuts"

between the flywheel and the Torque Converter. I have the 4 new donuts but the two flanges do not line up at all! They are a hair more then 3/8" out (!) if I mount the donuts on the flywheel flange.

If I - carefully - jack up the transmission, they come in line, but when I release the jack it is the same 3/8 again.

I did noticed that the transmission and torque converter are NOT supported at all on the frame. It basically hangs on the differential housing flange! Is this normal?

My question is: Is there not a missing bracket or strut bolted on the frame to support the weight of the transmission?? ( I can't reach the former owner anymore) And I don't see how I can otherwise lower the Engine 3/8" to bring it in line with the torque converter flange.

Does anyone had the same problem, and if so, how can I fix this? I know I have to come close to zero between the flanges otherwise the rubber donuts will be ripped apart again.

Every suggestion is welcome.

Thanks!!
