JA-SERIES WALK-BEHIND TROWEL — PARTS & OPERATION MANUAL — REV. #6 (11/14/05) — PAGE 31

JA-SERIES 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. Locate the cone point square head set screw (Figure 41)

and attached jam nut found on the side of the spider

assembly.

Spider Removal

1. Once it is determined that an adjustment is required, remove

the spider assembly from the gearbox shaft as follows:

Figure 41. Spider/Gearbox Removal

b. Loosen the jam nut and cone point square head set

screw, and carefully lift the

upper trowel assembly

off

of the spider assembly. A slight tap with a rubber mallet

may be necessary to dislodge the spider from the main

shaft of the gearbox.

Trowel Arm Removal

1. Each trowel arm is held in place at the spider plate by a hex

head bolt (zerk grease fitting) and a roll pin. Remove both the

hex head bolt and the roll pin (Figure 42) from the spider

plate.

2. Remove the trowel arm from the spider plate.

and Zerk Grease Fitting

3. Should the trowel arm inserts (bronze bushing ) come out

with the trowel arm, remove the bushing from the trowel arm

and set aside in a safe place. If the bushing is retained inside

the spider plate, carefully remove the bushing.

4. Examine the bronze trowel arm bushing insert (Figure 43),

clean if necessary. Replace bushing if out of round or worn.
