[Vwdiesel] Camshaft problems ---( Rabbits 1977 to 1984 )

[Mark Shepherd]

Then years later    Mark Shepherd   mentioned bolt bottoming
out ?    ----wow I have to find out..
So I went downstairs and picked up a cam -----     hole was
1.6 inch US deep..

BUT    this morning I went down and grabbed the
sprocket. ----and low and behold   ----the butt end of the
cam is very close to the face of the sprocket. ------LESS
than 40  thou inch us.   .

That makes for a very "Critical"   dimention.       ------SO
tighten bolt and remove and measure.
IF flush ? you got problems -----READ MY LIPS.       A  1000
foot    pounds torque would never fix
that sprocket to shaft.

Problem could be a PO installed sprocket or  a   VW mistake.

To make measurement VALID    tighten to specks only  ----at
least  --- at first.

Hagar.

surface AND grind a few thou off cam taper front face and
same to bolt length>>>>>
