MAINTENANCE

Trowel Arm Removal

Remove the two remaining Zerk grease fittings and Allen

head screws from the spider assembly (Figure 48).

Figure 48. Trowel Arm Removal

Blade Replacement

It is recommended to replace

all

of the trowel blades at the

same time. If only one or some of the blades are changed,

the machine may wobble or bounce and will not finish

concrete consistently.

1. Place the trowel on a flat, level surface and pitch the

blades as flat as possible.

2. Remove the two bolts and lock washers securing the

blade to the trowel arm (Figure 49), then remove the

blade.

3. Wire brush and remove all concrete and debris from all

six sides of the trowel arm. This is important to properly

seat the new blade.

4. Install the new blade onto the trowel arm, maintaining

the proper blade orientation as noted during removal.

Secure with the bolts and washers that were removed

earlier.

5. Repeat steps 2–4 for the remaining three blades.

Reassembly

1. Clean the wear plates and thrust collar, and examine

the entire spider assembly. Use a wire brush to remove

any concrete or rust buildup. Replace any spider

components that are damaged or out-of-round.

2. Inspect the bronze trowel arm bushing, and clean

it if necessary. If the bushing is damaged, worn, or

out-of-round, replace it.

3.  Reinstall the trowel arm bushing onto the trowel arm.
4.  Repeat steps 2–3 for each trowel arm.
5.  Make sure the spring tensioner is in the correct position

to exert tension on the trowel arm.

6. Insert all trowel arms with levers (and bronze bushings

already installed) into the spider plate. Align the grease

holes on the bushings with the grease hole fittings on

the spider plate.

7. Lock the trowel arms in place by tightening the Zerk

grease fitting hex head bolts and jam nuts.

8.  Reinstall the blades onto the trowel arms.
9.  Install the stabilizer ring onto the spider assembly.
10.  Lubricate all grease points (Zerk fittings) with premium

lithium 12-based grease, conforming to NLG1 grade #2

consistency.
