Brake & Brake Spring Adjustment; Pto Clutch Adjustment - Simplicity Regent Series Operator's Manual

BRAKE & BRAKE SPRING
ADJUSTMENT
1. Disengage the PTO, stop the engine, block the
wheels, remove the ignition key, and engage the
parking brake.
2. Remove the mower deck (see Mower Deck
Removal).
3. Locate the brake spring (A, Figure 25) and adjust-
ment nut (B).
4. With the parking brake engaged, measure the com-
pressed spring length. The spring should be 1-11/16"
- 1-3/4" (4.2cm - 4.4 cm) when compressed.
If the spring is not within this range, turn the adjust-
ment nut (B, Figure 25) to compress or release the
spring.
If this adjustment does not correct a braking problem,
see your dealer.

PTO CLUTCH ADJUSTMENT

Check the PTO clutch adjustment after the initial 25 hour
break-in period and then after every 250 hours of opera-
tion. Also perform the following procedure if the clutch is
slipping or will not engage, or if a new clutch has been
installed.
1. Remove key from ignition switch and disconnect
spark plug wires to prevent the possibility of acciden-
tal starting while the PTO is being adjusted.
2. See Figure 26. Note the position of the 3 adjustment
windows (A) in the side of the brake plate and the
nylock adjustment nuts (B).
3. Insert a .012"-.015" (2,5-4mm) feeler gauge (C)
through each window, positioning the gauge between
the rotor face and the armature face as shown in
Figure 27.
4. Alternately tighten the adjustment nuts (B, Figure 26)
until the rotor face and armature face just contacts the
gauge.
5. Check the windows for an equal amount of tension
when the gauge is inserted and removed, and make
any necessary adjustments by tightening or loosening
the adjustment nuts.
NOTE: The actual air gap between the rotor and arma-
ture may vary even after performing the adjustment pro-
cedure. This is due to dimensional variations on compo-
nent parts, and is an acceptable condition.
6. Check the mower blade stopping time. The mower
blades and mower drive belt should come to a com-
plete stop within five seconds after the electric PTO
switch is turned off.
7. Perform the BLADE BRAKE CHECK found in the
