[Vwdiesel] More Quantum Questions?

The intermediate shaft pulley is the -big- one just below the injection
pump. The intermediate shaft drives the oil pump and vacuum pump, and is
the only timing belt driven pulley that does not have teeth. Unless some
knuckledragger has applied too much brute force in removing it, an
intermediate shaft pulley is good for life.
The timing belt is tensioned by the small pulley directly under the
camshaft sprocket. There is a stud in the head that runs through the
tensioner, which has an offset bolthole that lets you twist the idler
around the stud to increase or decrease the tension on the belt. The
special tools mentioned are the tensioner wrench, which has two pins to
engage holes on the pulley, and a tool that measures the deflection of
the belt to tell you when you're at the right tension.
I've never owned a Quantum diesel, nor worked on one that wasn't already
smashed, so I can't help you with the wrench for the crankshaft pulley
on the QTD.

> I want to replace the timing belt although the current one & belts look fairly new. However, I can't figure out how to remove the belts from the water pump & power steering pump. Searched my Quantum Bentley but couldn't find an answer. The Bentley says the timing belt should have a particular tension to it & specifies a particular VW tool for it. I have ordered a new timing belt tensioner but in looking at the Bentley & looking at my car, there is what is described as an "intermediate shaft pulley" which is an idler pulley for the timing belt. Does this tend to wear out or is it good for ever? Also there is mention of a special wrench to turn the engine over at the crankshaft pulley. Space appears limited due to the radiator which isn't the case on my Dasher. Should I buy these special tools & if so, where?
