MAINTENANCE
BLADE CARRIER INSTALLATION
Clean the splines on both the blade carrier and output shaft. Position carrier on the gear box output shaft and
install flat washer and 1" hex nut. Tighten nut holding blade carrier to minimum 450 ft. pounds, strike the
carrier on the hub several times with a heavy hammer to seat the hub. Use a suitable spacer over the nut to
prevent damage to the nut and threads. Retighten the nut to 450 ft. pounds. Install and spread cotter pin.
NOTE: After a few hours of operation always recheck blade carrier retaining nut torque.
Avoid personal injury. Do not work under cutter without support blocks to keep frame from
falling.
SLIP CLUTCHES
A slip clutch is incorporated on each outboard driveline. The slip clutches are designed to slip, absorb the
shock load, and protect the drivelines of the mower.
After the first hour of operation, the slip clutches should be checked for overheating. After this first check,
inspect weekly or anytime there is overheating. To adjust the slip clutch, tighten the spring bolts 1/8
(maximum) turn at a time. See Figure MntP-R-0018 for minimum dimension. DO NOT tighten springs beyond
1-15/32" length (from top of washer to pressure plate).
Each slip clutch should be checked periodically and adjusted to compensate for wear. The lining plates are 1/
8" thick when new. Replace after 1/32" wear. If the mower has been idle for an extended period of time, or in
wet weather, before operating check to be sure the friction lining plates are not rusted/frozen together. Should
this occur refer to the procedure described in the "Seasonal Clutch Maintenance" section on the next page.
There are four friction lining plates in the slip clutch. These should be checked weekly for oil or grease, wear,
and moisture which could cause corrosion on the drive plates.
TIRES AND WHEELS
Before working on any tires and wheels make certain the Cutter is jacked up high enough and securely
supported. When installing laminated or airplane tires, be sure the flat side of the lug nut is against the Wheel.
When installing Sectional Tires and Wheels note the direction of travel and the curvature of rubber segments in
the tire (See Assembly Section). Do not exceed 15 M.P.H. on Sectional Tires. When removing Airplane Tires,
let all of the air out of the tire before removing lug nuts or wheel bolts or nuts. Remove valve core to make
certain that there is no air pressure left in tube before separating wheel halves to dismount tires. DO NOT
LOOSEN WHEEL CLAMP BOLTS BEFORE PRESSURE IS REMOVED FROM TUBE AND TIRE TO
PREVENT EXPLOSIVE SEPARATION OF WHEEL HALVES WITH POSSIBLE SERIOUS BODILY INJURY.
Do not exceed 20 M.P.H. on Airplane or Rib Implement Tires.
Maximum airplane tire inflation pressure is 50 PSI, minimum inflation pressure is 20 PSI. Inflate ribbed
implement tires to manufacturer rated PSI as shown on the tire sidewall.
