Trowel Arm Adjustment

Shown in (Figure 46) is the adjustment fixture with a trowel arm

inserted. As each trowel arm is locked into the fixture, the arm bolt

is adjusted to where it contacts a stop on the fixture. This will

consistently adjust all of the trowel arms, keeping the finisher as

flat and evenly pitched as possible.

1. Locate the trowel arm adjustment tool P/N 1817. Set the

adjustment tool for a clock-wise blade rotation, meaning the

fixture arm is in the "UP" position.

Trowel Arm Flatness Test

1. Using a piece of 3/4 inch thick steel plate or any surface which

true

and

flat

, check all

six sides

of each trowel arm for

flatness.

2. Check each of the six sides of the trowel arm (hex section

only) using a ten thousands of an inch (max.) feeler gauge

(Figure 45) between the flat of the trowel arm and an

tremely flat

test surface.

3. If the trowel arm is found to be

uneven

bent

, replace the

trowel arm. A bent trowel will not allow the trowel to operate

in a smooth fluid rotation.

4. Next, check each of the six sides of the round machined shaft

section of the trowel arm. Each section should have the

same

clearance

between the round of the trowel arm shaft and the

test surface.

Trowel Blade Removal

1. Remove the trowel blades from the trowel arm by removing

the two hex head bolts (Figure 44) from the trowel arm. Set

blades aside.

any build-up of concrete from all six sides of the

trowel arm. Repeat this for the remaining three arms.

Trowel arms can be damaged by rough

handling or by striking exposed plumbing or

forms while in operation.

ALWAYS

look-out

for objects which might cause damage to the

trowel arms.
