Checking Carrier Frame Front–to–Rear
Pitch
The carrier frame must have a pitch of a 1/4 in. (6 mm)
over the length of 24 inches (6.1 mm) on the carrier
frame.
1. Measure out 24 inches (6.1 mm) on the carrier frame
(Fig. 50).
2. Measure carrier frame height at location A (Fig. 50).
3. Measure carrier frame height at location B (Fig. 50).
4. The height at location A must be a 1/4–3/8 in.
(6 mm – 10 mm) lower than location B (Fig. 50).
5. If the carrier frame is not correct, move caster spacers
to make it a 1/4–3/8 in. (6 mm – 10 mm) pitch
(Fig. 50). Move spacers from top or bottom to make
the correct pitch.
6. The tire pressure may also be adjusted slightly to make
a 1/4–3/8 in. (6 mm – 10 mm) pitch.

1. Stop the engine, remove the key and disconnect the
spark plug wire(s) from the spark plug(s).
2. Adjust the tire pressure in all tires to specifications on
page 28.
3. Measure carrier frame height at location A (Fig. 51).
4. Measure carrier frame height at location B (Fig. 51).
5. If the carrier frame height is not the same move
spacers from top or bottom of caster wheel, to make it
level. The tire pressure may also be adjusted slightly to
make it level.
