TROWEL ARM ADJUSTMENT FIXTURE

The trowel arm adjustment fixture (20801) is reversible. By rotating the arm clamping fixture
and the ring bolt, both left hand and right hand trowel arms may be adjusted. Before attempting
adjustment, determine whether the trowel arm is right handed or left handed. When adjusting
left hand trowel arms use the side of the fixture marked “L”. When adjusting right hand trowels
arms use the opposite side. The adjustment bar will be set on “36” for the Walk-behind trowel
arm.

ADJUSTMENT PROCEDURE

1.

Remove all trowel arm assemblies (1 & 2 arm and attached lift lever) from suspected
maladjusted spider plate.

2.

Remove lift lever (2) from trowel arm (1) by first loosening jam nut (3) then square head
screw (4). If upon inspection (method left to discretion of serviceman) any trowel arm (1)
is found to be in a bent condition, it must either be brought back to its original straight
condition (method left to the serviceman’s discretion) or replaced with new part.

3.

Replace lift levers (2) on new or straightened arms (1) by reversing procedure as
described above.

4.

Place trowel arm assembly (1 and 2) in fixture (5) with lift lever (2) butting up against
fixture. Clamp in place with bolts (6).

5.

Loosen locknut (7) and screw carriage bolt (8) down to full depth allowable. This will
provide for ample clearance to swing precision ground adjustment bar (9) over head of
carriage bolt. Adjustment bar (9) is stamped for appropriate size of machine. Swing
appropriate side directly over carriage bolt (8) and secure in place with bolt (10).

6.

Adjust carriage bolt (8) upwards until contact is made with adjustment bar (9); holding
carriage bolt in position with one wrench, tighten locknut (7) to secure in position with
second wrench.

7.

This same procedure is to be followed with ALL arms from spider plate assembly, and
will ensure correct and exact adjustment.
