Rotate the shaft so that the keyway is pointing toward the #1 injector.Install the dial indicator.Remove the side bolt and get a longer one so you can lock the shaft position. With some pre-load on the indicator, rotate the shaft CCW. If the indicator reading immediately moves when you begin rotating the shaft, keep rotating CCW until it stops and zero the gauge.If the indicator reading did not change when you began rotating CCW then zero the gauge.Rotate CW until you get to the desired indicator reading. Lock the shaft with the side bolt.Place the hub on the shaft with the lock pin in place.Tighten the hub nut.Replace the side bolt with the proper bolt.The usual disclaimers apply - see signature.
The side bolt just pinches the shaft. There is no slot it goes into. It can hold the shaft at any point in its rotation. The sequence I mentioned previously is fairly comprehensive. It's easier than you might think.Quote from: libbydiesel on June 22, 2016, 11:02:03 pm Rotate the shaft so that the keyway is pointing toward the #1 injector.Install the dial indicator.Remove the side bolt and get a longer one so you can lock the shaft position.

On my ALH automatic, I didn't do anything about the pin hole mismatch. The camplate/rollers are pushing the sprocket CCW and so I just installed the hub with the pin pushed against the side of the hole in that direction. It's definitely close enough to be on the correct tooth during a belt install. For fine timing I use the pulse adapter. You could do similar with the dial indicator. Places like MyTurbodiesel or tdi club have pictorials on changing the timing belt. The pump timing will be different for an mTDI, though. Setting the pump timing up for an mTDI would be the same as the 1.5/1.6 except instead of loosening the pump mounting bolts and rotating the pump, you loosen the sprocket to hub bolts and rotate them relative each other.
