5. Perform steps in the following sections Frame Set Up,
Checking Front–to–Rear Pitch and Checking
Side–to–Side Leveling.
Frame Set Up
Checking Carrier Frame and Deck
Alignment
1. Stop the engine, remove the key and disconnect the
spark plug wire(s) from the spark plug(s).
2. Place a long straight edge on top of the engine deck as
shown in figure 50.
3. At the carrier frame cross tube, measure location "A"
height (Fig. 50). This measurement must be 2–13/16
in., plus or minus a 1/4 in.
4. If the height at location "A" is not correct, adjustment
is needed.
5. Loosen the carrier frame mounting bolts on both sides
of the machine (Fig. 50).
6. Align the carrier frame and engine deck to match
2–13/16 in., plus or minus a 1/4 in. at location "A"
(Fig. 50).
7. Tighten the carrier frame mounting bolts on both sides
of the machine.

Checking Engine Deck Height
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 30.
3. Measure engine deck height at location "A" (Fig. 51).
4. Measure engine deck height at location "B" (Fig. 51).
5. If the height at location "A" and "B" are not the same,
change tire pressure slightly to make them the same.

Checking Carrier Frame Front–to–Rear
Pitch
The carrier frame must have a pitch of a 1/4 in. over the
length of 24 inches on the carrier frame.
1. Measure out 24 inches on the carrier frame (Fig. 52).
2. Measure carrier frame height at location "A" (Fig. 52).
3. Measure carrier frame height at location "B" (Fig. 52).
4. The height at location "A" must be a 1/4–3/8 in. lower
than location "B" (Fig. 52).
5. If the carrier frame is not correct, move caster spacers
to make it a 1/4–3/8 in. pitch (Fig. 52). 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. pitch.
