Trowel Arm Adjustment

Use the following procedure to check and adjust trowel arms, and check for worn or damaged components when it becomes apparent that the trowel is finishing poorly or in need of routine maintenance.

Look for the following indications. Trowel arm alignment, worn spider bushings or bent trowel arms may the cause.

Are blades wearing unevenly? Is one blade completely worn out while the others look new?

Does the machine have a perceptible rolling or bouncing motion when in use?

Look at the machine while it is running; do the guard rings “rock up and down” relative to the ground?

1.Place the trowel on a FLAT, LEVEL surface.

2.A level, clean surface area to test the trowel prior to and after is essential. Any unlevel spots in the floor or debris under the trowel blades will give an incorrect perception of adjustment. Ideally, a 5 x 5 ft. (1.5 x 1.5 m) three-quarter inch (19 mm) thick FLAT steel plate should be used for testing.

3.Pitch the blades as flat as possible. The adjustment bolts should all barely make contact with the lower wear plate on the spider. If one is not making contact, adjustment will be necessary.

4.Figure 34 illustrates, "incorrect alignment", worn spider bushings or bent trowel arms. Check that the adjustment bolt is barely touching (0.10" max. clearance) lower wear plate. All alignment bolts should be spaced the same distance from the lower wear plate.

Spider Removal

Remove the spider assembly (Figure 36) from the hydraulic motor shaft as follows:

1.Remove the protective plug located on the underside of the spider to gain access to the screw securing the spider plate to the hydraulic motor shaft.
