[Vwdiesel] injector pump leaks

[James Hansen]

It can be done, but it is certainly not much more to have the pump on the
bench.  You already pulled the sprocket to get this far, and a few more
bolts has the thing on the bench, and really, that is preferred- you can see
better, and evaluate the bushing wear then easier.
Have a look at this soon Doug, as the leaking fuel can get on the belt and
destroy it with annoying consequences.

One thing to note, there have been a lot of leaking input shaft seals lately
it seems.
Tight belts kill the bushing, and then it leaks.  Not that mine is any
special car, but I worked on my old Jetta the other day (currently under new
ownership) and the IP is still fine at 580000+ kms.  The belt has never been
tight, in fact, I bet many would look at it with a cold engine, and say it
was too loose.
The belt should be able to slide back and forth on the injection pump
sprocket with very moderate effort.  To say, an 8 year old should be able to
just move it sideways on the sprocket grooves.  Any tighter, and the pump
wears.  If you hear a whine from the belt area, it's waaaaay too tight.

How many places can the injector pump leak? I'm getting a wet garage floor
with a fuel leak from the front of the engine. I've replaced the return hose
and everything topside looks dry. I suspect the shaft seal. How difficult is
a shaft seal replacement with the pump still mounted to the engine. Any
other places to look for leaks?
