Installation Of The Water Pump Shaft - Rotax 125 MAX DD2 Repair Manual

Installation of the water pump shaft

➩ Secure the impeller of the water pump (Item 4)
by means of a dowel pin (Item 7).
➩ Screw in the water pump shaft (Item 6, Fig. 74)
with rotation to the left and secure with Loctite
221 (Violet).
◆ Note:
The water pump drive thread is a left
hand thread.
➩ Screw the water pump flange (Item 1) to the
housing (Item 7) with the shaped sealing ring
(Item 2) by means of the 4 Taptite screws (Item
8).
◆ Note:
Use only the special Taptite screws
specified by ROTAX to secure the
water pump flange. These are self-
tapping. Other types of screws can
destroy the threads in the housing.
Lack of sealing would then quickly
follow.
