4.1.1.7 ADJUSTING THE BEGIN OF DELIVERY
If an injection pump must be replaced, the begin of delivery must be re-adjusted by determining the shim
thickness anew.
DETERMINING THE SHIM THICKNESS
The old injection pump and shim are not required for this procedure.
NOTE: From 4/95, the mounting depth of the injection pump has been increased by 10 mm so that the
EP code changes from 70 to 170 and the basic dimension L
0
of the injection pump from 109
mm to 119 mm.
The metod of determining the thickness of the shims for the old versions remains the same.
Proceed as follows:
In the column marked "EP", read the EP code for cylinder 3 on the type plate on the rocker cover,
e.g. 070 or 170 (reading sequence: line 1 = cylinder 1, line 2 = cylinder 2, etc.).
