[Vwdiesel] Pump timing/Reading a dial indicator

[Mark Shepherd]

What you say sounds right for the gauge ... except how do you know you have
exactly 2mm preset for the small gauge to be accurate Does you gauge
default to zero on the small gauge accurately.? Is it possible that you are
short of one revolution on the main dial? Does your cam need relocking in
correct position?

>   I changed the timing belt on my Volvo/ VW 2.4L diesel and have been
trying to set the injection timing. I must be doing something wrong because
it will not run.

camshaft are in the correct position according to my manuals. That's fairly
simple, so it must be the injection timing. I drove this car into my garage
so it did run prior.

cam I had to turn it clockwise about an inch, inch and a quarter in order
to lock the cam in the correct position. I thought to my self the timing
must be off.

>   I have followed my Volvo Factory manual step by step a hundred times
and it still doesn't run. The only thing I can think of is I am not reading
the dial indicator correctly. By looking at the gauge is seems to be a no
brainer.

>   The gauge is a factory gauge so it is the correct one. It reads both
metric and standard. The black marks and numbers are metric and those are
the ones I have been using. It has a 5mm measuring range. The space between
the marks equals 0.01mm

>   The marks go from zero clockwise one full rotation would be 0.50
>   0.05,  0.10, 0.15, 0.20, 0.25, 0.30, 0.35, 0.40, 0.45, 0.50
>
>   To go beyond 0.50 you keep counting on the second rotation.
>
>   0.05=0.55, 0.10=0.60, 0.15=0.65, 0.20=0.70, 0.25=0.75, 0.30=0.80. 0.80
is where I need to be. I can tell I'm on the second rotation by the smaller
gauge which goes from
>   1mm to 5mm. I have to set it on a 2mm preload when I am on the second
rotation the needle will read between the 2 and the 3.
>
>   Is this correct? I have never used one before. Can anyone think of what
I might be doing wrong? I hate to have it towed to the dealer. I have
worked on cars since I was a teenager and have always been successful in my
repairs; it kills me to have it towed to a repair shop.
