I have a '62 Mk II, BJ7 that I am in the process of restoring. The
transmission (center shift) was fully functional when I took the car off the
road so
I am only intending on replacing the seals and gaskets. I have removed the
bell housing to replace that gasket (as well as the input shaft seal) and when
I compare the thickness of the old gasket with the replacement, I find the
replacement gasket is much thicker - 0.029" thick compared with 0.011" for the
old. I expect the new gasket will compress some when installed, but not
enough to make up for the 0.018" difference in thickness. There are two shims
positioned in front of the input shaft bearing that combined are 0.007" thick.
I measured the depth of the recess in the bell housing where the shims are
located - 0.213" and the bearing stands proud of the housing by 0.222". This
results in the bearing being free axially by 0.013". I couldn't find
anything in the Bentley or Haynes manuals that talks about what this should
be.
Does anyone know?
What I can do is check the compressed thickness of the new gasket and add a
shim equal in thickness to the difference between the two gaskets, but is this
what I should do?
Also, are there any concerns with gaskets at the trans housing to adapter or
adapter to OD?
While I'm at it, can anyone help me with what transmission I have? There is
a number stamped into the main housing - M 2122. As mentioned above, there
are only shims at the input bearing, not the plate and spring plate mentioned
in the manual (the Moss catalog seems to indicate the BJ8 trans used shims
where the older models used a plate and spring plate). I'm wondering, since I
need a shifter bushing (nothing there at present) and I don't know if I need
the brass type for older transmissions or the nylon type used on newer ones.
Happy New Year
Kurt
