6. Slide the smaller diameter clamp onto the
extruded end of the formed metal tube and insert
this end of the tube into the hose section. Position
the tube so its formed offset leads down and
away from outlet, perpendicular to the pump.
Install the clamp onto the hose and position the
tangs of the clamp parallel to those of the first
clamp. See Figure 11-48.
Figure 11-48. Transfer Tube, Hose and Water Pump
as Assembly.
7. Holding the pump assembly elevated, assemble
the transfer tube to the 90° fitting in the
crankcase as follows:
a. For new/first time tube installation:
1. Place a new ferrule/compression ring in the
90° fitting of the crankcase and loosely
install the hex cap onto the threads of the
fitting.
2. Insert the plain end of the transfer tube
through the hex and compression ring.
b. For reinstallation of an existing tube:
1. Insert the end of transfer tube, with the
compression ring, into the 90° fitting of the
crankcase.
2. Start the hex cap onto the threaded section
of the fitting.
IMPORTANT: The 90° fitting in the crankcase is
installed and sealed at the factory, in a specific
position. Special tools and procedures are
involved. Do not loosen, remove, or alter the
mounting position of this fitting at any time.
8. Carefully push the water pump down from the
raised position, thereby rotating the tube 90°
within the end connections. Guide the pump into
position over the O-Ring; aligning the two
mounting pins and five screw hole locations. See
Figure 11-49. Start all of the screws, with the
longer screw nearest the pump outlet. Torque the
screws to 9.9 N·m (88 in. lb.) in the sequence
shown in Figure 11-51.
