Checking Trowel Arm Straightness

Trowel arms can be damaged by rough handling, (such as dropping the trowel on the pad), or by striking exposed plumbing, forms, or rebar while in operation. A bent trowel arm will not allow the trowel to operate in a smooth fluid rotation. Ifbenttrowelarmsaresuspect, check for flatness as follows, refer to Figures 35 and 36:

2Trowel Arm Hexagonal (Hex) Shaft Section

4Roll Pin Hole

5Blade Attachment Bolt Hole (One of Three)

6Flat of Hexagonal Shaft (Top of Arm)

Figure 35. Trowel Arm

1.Use a thick steel plate, granite slab or any surface which is true and flat, to check all six sides of each trowel arm for flatness.

2.Check each of the six sides of the trowel arm (hex section). A feeler gauge of .004" (0.10 mm) should not pass between the flat of the trowel arm and the test surface along its length on the test surface. (Figure 36 item 3) .

3.Next, check the clearance between the round shaft and the testsurfaceasoneoftheflathexsectionsofthearmrestson thetestsurface. Rotatethearmtoeachoftheflathexsections and check the clearance of the round shaft. Use a feeler gauge of .005" (0.127 mm). Each section should have the same clearance between the round of the trowel arm shaft and the test surface.

4.If the trowel arm is found to be uneven or bent, replace the trowelarm.
