7. Lock the assembly in a vise and set up a dial
indicator to read the end play. To measure the
end play, rotate the shaft while pushing in one
direction, and set the dial indicator to 0. Now
rotate the shaft and pull in the opposite
direction while reading the dial indicator. The
end play should be 0.001 to 0.005 in. (0.025 to
0.127 mm). If the end play is incorrect, use
different shims to obtain the correct end play.
Shims available from the Service Parts
Department:
• 0.020 in. (0.500 mm)
• 0.007 in. (0.177 mm)
• 0.005 in. (0.127 mm)

Jackshaft Assembly
The unit is equipped with a jackshaft that contains
special sealed bearings. The jackshaft bearings
should be checked when the belts are replaced.
Spin the jackshaft with the belts removed and
listen. Unusually loud bearing noise indicates the
jackshaft bearings should be replaced.
NOTE: The jackshaft assembly can be
disassembled and reassembled without removing
the brackets from the ends of the housing.
Disassembly
1. Remove the jackshaft assembly from the unit.
2. Remove the snap rings.
3. Remove the shaft from the housing by tapping
on either end of the shaft with a soft hammer.
4. Remove the bearing from the shaft by
supporting the bearing and tapping on the end
of the jackshaft.
5. Remove the bearing from the housing with a
hammer and punch.
6. Clean and inspect the parts, but do not clean
the bearings in solvent. Replace the parts that
show significant wear or damage.
