REMOVE SINGLE LEVER PLATE (988105,

can work separately to adjust tracking on uneven

REPLACING THE HYDRO PUMP BELT

1. Place speed control levers in neutral position

(988105, 106, 107, 108, 109, 113).

2. Remove mower belt from mower clutch sheave

(Figure 19).

3. Remove pump belt idler spring from eye bolt.

4. Remove belt from engine sheave and pump

pulleys.

5. Install new belt on engine sheave and pumps.

6. Reconnect idler spring to idler.

CLUTCH ADJUSTMENT

If clutch fails to engage or disengage properly or
begins to make abnormal noise, check the air gap
adjustment at the three inspection slots.

To check:

1. Stop engine, remove key and wait for all hot parts

to cool.

2. Measure the air gap between the armature and

the rotor.

Minimum: A .005" feeler gauge should slide
between armature and rotor with slight contact.

Maximum: A .023" feeler gauge should slide
between armature and rotor with slight contact.

3. Repeat for each inspection slot.

To adjust:

1. If necessary, loosen gap adjustment nuts until a

.005" feeler gauge ﬁts between armature and
rotor.

2. Slide a .012" feeler gauge between armature and

rotor.

3. Tighten gap adjustment nut until there is slight

contact on feeler gauge.

4. Repeat steps 1 – 3 at each inspection slot.

NOTE:

Adjust air gap as evenly as possible.

5. Start unit, engage and disengage PTO.

6. Shut off unit.

7. Recheck air gap and adjust if needed.

WARNING:

An extension spring, when

extended, stores energy and can be
dangerous. Always use tools speciﬁcally
designed for installing or removing an
extension spring. Always compress or
extend springs slowly.
