MAINTENANCE
BLADE CARRIER INSTALLATION
Clean the taper and keyway 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 the nut holding the 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 Mnt-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.
