[Vwdiesel] RE: Intermediate shaft bearings

[Brian or Pam Harrison]

Hi Dave;
I had to change the intermediate shaft on my 85 Jetta td a few
years ago and did it with the engine in the car, middle of winter,
outside. I pulled it out on the right side in the wheel well after
removing the plastic fender liner. I don't recall now, but I may have
lowered the engine a little.
There are two bearings, one at each end and the farthest one in is
smaller than the outer one. They are not listed as a part at the VW
dealer and are considered part of the engine block assembly on
VWs parts catalogue. That is also the reason why they are not
discussed in the Bentley Manuals since VW didn't have a
procedure to change them available for publication.
The bearings are available from engine rebuilders and I had found
out that they were the same as the bearings used in the 1.7 L Gas
VW engine that was used in the Omni / Horizon models in the late
70s and early 80s. It is important to insure that the oil holes in the
replacement bearings are lined up when putting them in otherwise
you will not get any oil flow to the shaft.

I had mine changed a few years later when I had the block out to
rebuild it and ended up with oil pressure problems. I eventually
traced the problem to missing steel bushings for the vacuum pump
drive shaft that the engine rebuilder had taken out when they
cleaned my block. These bearings are another item that is not
listed as a part at VW and is considered a part of the block. With
these bushings out the oil was pouring back into the oil sump from
the lower oil gallery channel.

That's briefly my encounter with intermediate shafts and low oil
pressure. The rest is a long story as well.
