3. Insert the cross shaft and bearing into the fan pulley
end of the housing.
4. Install the wave washer on the engine pulley end of
the cross shaft.
5. Install the other bearing on the engine pulley end of
the cross shaft.
6. Install the snap ring on the engine pulley end of the
cross shaft.
Installation
1. Place the cross shaft in position. Make sure with the
engine pulley end is located on the engine/cross
shaft belt side.
2. Install and tighten the cross shaft mounting bolts.
3. Make sure the key is in place in the engine pulley
end of the cross shaft.
4. Place the cross shaft/engine pulley on the cross
shaft. Position it axially using block P/N 2042435
between the pulley and the cross shaft mounting
bracket and tighten the pinch bolts.
5. Make sure the key is in place in the fan pulley end of
the cross shaft.
6. Place the cross shaft/fan pulley on the cross shaft,

Idler Assemblies
The idler assemblies contains special sealed bearings.
The bearings should be checked when the belt is
replaced. Spin the idler pulley with the belt removed
and listen. Unusually loud bearing noise indicates the
idler bearings should be replaced. The idler assembly
for the idler pulley in the engine/cross shaft belt is
shown below. The other idler assemblies are similar.
See the appropriate Parts Manual.
