Live Caster Adjustment
Caster readings are taken on the front wheels, using the TLT-30.
1)
Hang the TLT-30 on the left front wheel clamp to measure caster.
2)
Install brake pedal depressor and lock brakes so they do not rotate. With
power brakes start the engine to install brake pedal depressor.
3)
Release the pin on the turntable. This allows the wheel to pivot, or turn,
freely.
4)
From a straight-ahead position, turn the wheel
out
20 degrees. (Use the
scale on the turntable to confirm swing.)
5)
Level the TLT-30, using the SAI scale on the top of the TLT-30; adjust
the caster bubble to zero, using the knob on the body of the TLT-30.
6)
Turn the wheel
in
a total of 40 degrees, or until the wheel is 20 degrees
in
on the scale of the turntable.
7)
Read the number corresponding to the bubble on the caster scale; (Fig. 21) Record
and compare the reading to the desired specifications.
8)
To perform a live caster adjustment, rotate the top caster scale to the
corresponding reading taken previously. i.e. left is +1 degree.
9)
Proceed with the adjustment to meet specifications.
10)
Repeat the caster measurement to verify live caster adjustment.
