[Vwdiesel] timing belt and adjusting timing

[peter blake]

  I'm about 90% convinced my pump timing is a little advanced.
So I decided to get adventurous and do a little Hagar tuning.
I pulled the timing belt cover because I at first thot that the
third bolt was accessed fm that side. What I found is that my
timing belt has a groove in it about a quarter inch in fm the
pump side and that the outside of the belt appears to be machining
itself against the belt tensioner flange. So I guess I need to 
replace the belt and tensioner and probably the water pump while
I'm there.  I've generally used autohausz az in the past for parts
and they have been very good but I'm open to suggestions if anyone
has a better supplier. I'm thinking that a new tensioner should cure
the self machining problem. Anybody have experience w this?
 As for the pump, I loosened all three bolts and tried to tap it
w a rubber mallet and couldn't get it to move one iota. Any tips?
