CARRIER BEARING AND SPLINED SHAFT INSTALLATION
Use the following instructions to install the carrier bearing and splined shaft to both
the stationary and movable dynos.
You will need the following parts:
• 32355056
Bearing, Flange (2)
• 36801080
Bolt, 1/2-13 x 1.5", Flange-Hex (4)
• 62200010
Splined Shaft (2)
1
Loosely install the inner carrier bearing using two 1/2-13 x 1.5-inch flange bolts.
2
Apply a small amount of grease to the first two inches of the splined shaft.
3
Push the splined shaft into the dyno until it stops (bottoms). Pull the shaft
assembly back slightly, approximately 1/8-inch. Verify the sleeve on the shaft is
lined up with the set screw in the bearing.
4
Lift lightly on the shaft finding the mid point of the vertical travel.
5
While applying just enough upward pressure to support the shaft, tighten the two
1/2-inch bolts.
6
Torque the bearing set screws to 10-13 ft.-lbs.
Verify the set screw is lined up on the shaft sleeve. Do not tighten the set
screw on the splines or sleeve edge.
