4. Fitting
Fitting is carried out analogously to the removal but in reverse sequence, whereby
attention must be paid to the following:
D Screws 16 for fastening spray nozzles 11 (view II-II) must be secured with
LOCTITE No. 243.
D O-rings 18 must be replaced. Parallel pin 17 ensures correct fitting of spray
nozzle 13.
Remark: Bores for bearing bushes 9 in housing 7 and pump support 4 are ma-
chined together and marked accordingly. Therefore, never interchange the pump
supports and take special care of marks ’MA’ on assembly!
During fitting the clearances are to be determined in accordance with Clearance
Table 0330−1 ’Supply Unit’.
Switch on the lubricating oil pump and check the oil flow in the bearings and spray
