Replacing Jackshaft Bearings
• Remove the Poly Chain® guard cover and
bottom cover. Follow the instructions in the
Servicing Belts section to remove the Poly
Chain® belt.
• Measure the distance from the jackshaft end to
the bushing to place the bushing in the same
place on the new shaft. Write this measurement
down.
• After the belts have been removed, remove the
jackshaft sprocket. Remove the two screws in
the bushing and then screw one of the screws
into the threaded hole to push the bushing out of
the sprocket.
• You may have to strike the sprocket rim with a
dead blow hammer or leather mallet, NOT A
STEEL HAMMER, while applying tension with
the screw to break sprocket loose.
• Remove the Poly Chain® guard. The guard is
held onto the boom with four carriage bolts,
washers, and nuts.
