Bosch Diesel pump timing//ACV Engine

In this episode working on fixing my VW T4 2.5tdi ACV engine, I decide to set the diesel pump timing now rather than when the cylinder head is fitted because I think it will be easier to do now with the head out of the way. To be fair this is that a hard a job but you will require a dti gauge and adaptor.
Thank you for watching.

Tools required

10mm 12mm 13mm socket and ratchet
21mm on a breaker bar
Tool to hold the cam pump pulley
21mm spanner
DTi gauge
27mm socket to turn the engine from the crank/damper pulley

Quick description
You fit the DTI to the back of the injection pump through the timing port via a threaded adaptor that fits between the injector pipes in the pump head
Then Pre load the DTI
rotate the engine backwards(anti-clockwise) till the DTI needle stops moving.
Zero the gauge.
Rotate the engine back up to TDC.(clockwise)
measure the reading on the DTI
The measurement you are expecting (or aiming for) is .55mm.

If the measurement in more than .55mm the timing is too far advanced.

If the measurement is less than .55mm the timing is retarded.

Slight adjust can be made from the idle pulley, I wouldn't recommend to do this.

To adjust the timing you do the following.
Slacken the pump lock bolt via the 10mm headed bolt, remove wedge and nip up.
Slacken injection pump timing belt at the cam pulley.
Hold spanner on the injection pump sprocket pulley and slowly undo the pump lock.
Set the DTI to desired position.
lock pump by tightening the bolt.
Tighten cam pulley.
undo pump lock and refit wedge.
Recheck timing.
Once you are happy that the basic position is set, make sure all pulleys are tight, and the pump lock set to unlocked.
