13.3.10) Water pump housing — reassembly
See Pic. 124.
Place gasket Q and attach water pump housing W with 2 Allen screws M6x90
E and 3 Allen screws R M6x35 with lock washers to the ignition housing,
torque to 10 Nm (90 in.lb).
■ ATTENTION: The bottom Allen screw M6x35 T reaches into the water
chamber, therefore it is of stainless steel and fitted with a
sealing ring Y.
Visually check whether the impeller
scuffs in the pump housing. This
can be recognized by scuff-
ing traces in the pump
housing or on the impeller.
If necessary, the axial po-
sition of the impeller can
be corrected to achieve an
optimum gap (see Chap-
ter 13.3.8).
Insert O-ring U into water
pump housing and fit the
water inlet elbow I in the
position marked before
disassembly with 2 Allen
screws O M6x20 and
tighten to 10 Nm (90 in.lb).
◆ NOTE: The water inlet elbow is symmetrical and can be fitted turned
by 180° if required.
Fit coolant hoses and fix them with genuine hose clamps.
■ ATTENTION: Do not tighten hose clamps excessively in order not to
damage the hose!
