Why don't you first try tightening the belt against the drive gear?
It's done using the tensioner, an eccentric cam around which is placed
a pulley that bears on the belt. Tightening the cam will engage the
belt more with the intermediate shaft, and therefore the vacuum gauge
and the oil pump.
The stud that mounts the tensioner and its locknut comes out of the
head. The nut itself is 15 mm. Once loosened, you will need to somehow
get two pins into the holes in the eccentric cam. A Park Bicycle
headset (old style) wrench or old style bottom bracket wrench will do,
as will the purpose-made VW tool or a pair of bent long-nose pliers
with small tips. The idea is to get two pins into the two holes in the
cam with enough leverage to rotate the cam to tighten the belt.
Conventional wisdom says to tighten the belt so that it can just be
turned 45 degrees. However, a better measure is to tighten it so that
the belt can barely be moved over the top (valve or fuel injection)
pulleys with the fingers grabbing it.
This should do it for you if you don't have something like a seized
intermediate shaft.
