2. Remove knives and inspect holes for damage. Also watch for cracks in the disk around the holes.
3. Lube threads with anti-seize. Install bolts through knife and disk from bottom side of disk. Install new self-
locking nuts and torque them to 800 ft. lbs.
4. The knives should swing freely to absorb shocks from impact when striking objects.
WHEN CUTTING HEAVY BRUSH, KNIFE BOLTS SHOULD BE INSPECTED HOURLY
AND RETORQUED TO 800 LUBRICATED FT. LBS.

REPLACEMENT OF ROTARY DISK (TRB 50)
1. The bolts that attach the disk to the spindle must be grade 8. These 5/8 inch bolts are to be torqued to 204
dry or 180 ft. lbs lubed with Loctite 271.
2. A thread locking agent may be applied to threads of all mounting bolts before they are installed.
3. Disks must be inspected daily for hairline cracks between spindle mounting bolts or around the
knife mounting bolts. These cracks indicate metal fatigue caused by severe abuse. If cracks are
present the disk must be replaced.
4. Inspect the disk mounting bolts daily when checking tightness of knife mounting bolts. If a disk mounting bolt
is loose, it must be removed, threads cleaned, fresh thread locking agent applied, and tightened to proper
torque value.
5. If a knife mounting bolt is loose, the self locking nut must be replaced as a safety precaution. Lubricate
threads with anti-seize. Install bolts through knife and disk from bottom side of disk. Install self locking nuts and

fatigue caused by severe abuse. If cracks are present the knives and blade bar must be replaced.
4. Inspect the blade bar mounting bolts when checking tightness of knife mounting bolts. If a blade mounting
bolt is loose, it must be removed, threads cleaned, frest thread locking agent applied, and tightened to proper
torque value.
5. If a knife mounting bolt is loose, the self-locking nut must be replaced as a safety precaution. Lubricate
threads with anti-seize. Install bolts and self-locking nuts and torque to 2000 ft lbs.
