2. If the water pump by-pass hose fitting was
removed previously, apply pipe sealant with
® ®
Teflon (Loctite 59241 or equivalent) on the
threads and tighten it into pump. Orient the
fitting so the outlet points in the 11 o'clock
position as shown in Figure 11-44.

3. Check the sealing surfaces of the water pump
and crankcase. They must be clean and free of
any nicks or damage.
4. Apply a small amount of grease in several
locations to hold the new water pump O-Ring in
place. Install a new O-Ring in the groove of
crankcase. See Figures 11-45 and 11-46. Do not
use RTV sealant in place of the O-Ring, or
attempt to reinstall a used O-Ring.

5. Apply rubber lubricant to the inner surfaces of
the short hose section. Assemble the hose to the
outlet of the water pump and secure with the
larger diameter clamp. Orient the clamp so the
tangs extend out in the 3 to 4 o'clock position. See
Figures 11-47 and 11-48.
