lic pump.
– Pull out the driver (103/1).
– Remove both machine screws (103/2)
including spring washer (103/3), plate
(103/4) and gasket (103/5).
– After removing the timing cover retai-
ning screws (103/4) and taking off the
timing cover (103/6) the support mount
(103/9) is exposed and can be taken off
after removing the two screws (103/7)
with spring washer (103/8).
Note:
– On older L 30/L 40 / H.L 30 engines
there is no support mount for the hy-
draulic pump drive.

by a hoop. A blank cover is fitted in
place of the shutdown device; see
Fig. 104.

– Apply grease to the contact edge of the
shaft sealing ring.
– Before fitting, coat new seals on both
sides with sealant H.
