To insert the high-pressure pump shaft in the secondary sprocket
wheel, it may be necessary to swing the high-pressure pump
through several degrees (taper groove-lug fit [arrow]). Then rotate
high-pressure pump back into screwing position.

Replacing high-pressure pump:

When installing a new high-pressure pump, adapt the high-
pressure pump-sprocket wheel assignment. To do so, turn back
high-pressure pump at set-back part of shaft 45

°

 clockwise (top

view). Do not damage the shaft, especially the taper.

When installing the high-pressure pump support, adhere to the
screwing sequence.

Installation:

1. Tighten down to head (gap-free) hand-tight, sequence 1-2-3-4 

2. Tighten to final torque 13 51 2AZ
