CLUTCH SHOE TO FAN AND HUB MOUNTING
Apply light oil to the Torrington bearing in the center of the clutch shoe. Be sure that
no grease contacts the edge of the clutch or it could get transfered to the clutchbell.
Slide the clutch shoe onto the fan hub, press down and install four M4x8 button head
screws using Blue threadlock.
Dip a cloth in rubbing
alcohol and degrease
the threads in the end
of the engine crank-
shaft. Apply liquid oil
to the outside taper of
the engine crankshaft,
the entire taper should
be coated. Do not get
oil into the internal
threads. Use Triflow
or equivalent oil.
Slide the cooling fan assembly onto the engine. Locate the M6x15 socket
cap screw. Thoroughly clean this screw to remove any oil residue. Install
the fan assembly onto the crankshaft. Using a cloth wrapped around the
outside of the cooling fan held by your hand, tighten the M6x15 socket cap
screw until hand tight and check the runout of the fan assembly. Accept-
able runout is 0.002”, if more, remove the fan assembly and install again.
Once satisfied, remove the M6x15 socket cap screw, apply Blue thread
lock and secure in place.

If you plan to install a governor, it is best to fabricate the mount for the sensor at this
time, get it fitted and set the sensor gap before the fan shroud is installed.
Tighten these bolts
until they stop and
that’s it. Do not
torque these bolts!
Using a Dremel type tool or
similar, cut away a 29mm x
5.5mm slot.
Take the time now to make sure that the clutch shoe is prop-
erly seated on the fan assembly by looking at it from the side
and making sure there is no vertical movement as you slowly
turn over the engine. Experienced modelers willdial indicate
the clutch with an acceptable amount of runout of 0.002”
