ALIGNING THE CASTER WHEELS.

Application: All Models.

Tools Required:

1 each, 16 inch minimum length straightedge

2 each, 3/4 inch wrenches

1 each, torque wrench, 85 ft lbs (115 Nm.) capacity

with 3/4 inch socket.

1 each, 6 inch scale.

Proper front and rear caster wheel alignment is

essential to produce an even cutting action by the

flails. With use, caster bearings and axles will

eventually wear. Excessive caster bearing and axle

wear can contribute to an uneven cutting action. In

addition, a sharp blow delivered to the Floor Planer

(eg; being dropped to the surface from off a truck) can

also affect the caster wheel alignment.

Caster wheels are aligned during assembly with the

use of a specially designed alignment jig. However,

satisfactory results can also be achieved in the field by

following steps:

1) Position the Floor Planer on a suitable work

surface. If the Floor Planer is powered by an engine

and the engine is not to be removed, fuel and oil must

be first drained from the fuel tank and crankcase. If

extension cord or Floor Planer from the power source.

The normal position for aligning the caster wheels is

with the main frame perpendicular to the work surface.

Support the unit with proper blocking.

2) Shim washers of .015 inch (.381 mm) thickness are

sometimes utilized when fastening the front axle

assembly to the main frame. Install washers as

required. FIGURE 50. The fasteners that attach the

front axle assembly should be tightened until slight

tension is applied. Always position the 1/2 inch flat

washers against the slots provided in the axle

assembly.

3) Position the front casters so that their faces extend

approximately 7/16 inch (11.1 mm) beyond the bottom

surface of the main frame. Caster wheels have a slight

curvature on their faces. The measurement should be

taken at the high point of the curvature. FIGURE 51.

4) Push the rear casters towards the main frame until

the upper limit stop is encountered. FIGURE 52.

5) Place the straightedge between the front and rear

casters on the high point of the face curvature. Adjust

the front casters so that the gap between the straight-

edge and the bottom of the main frame is identical.

This gap figure is approximately 1/8 to 1/4 inch (3.17

to 6.35 mm). It is important that the straightedge be

positioned on both sets of casters in the same relative

position on the caster faces. FIGURE 53.

6) Tighten the fasteners with the torque wrench to 85 ft

lbs (115 Nm.). The addition of clamps will minimize

any movement or location change while tightening the

fasteners.
