C-4 FINISHER TROWEL — MAINTENANCE
■ Does the trowel have a perceived rolling or bouncing
motion when in use?
■ Look at the trowel while it is running, does the guard
ring “rock up and down” relative to the ground?
2. Start engine, and bring trowel blades up to full speed and look
for the following conditions:
a. Remove the zerk fitting and allen head screw desig-
nated by the letter "S" (Figure 25). In addition, on the
opposite side of the spider block there is another zerk
fitting and allen head screw, remove both of these
components.

the spider assembly from the gearbox shaft as follows:

A slight tap with a rubber mallet may be necessary to
dislodge the spider from the main shaft of the gearbox.
