The ball type torque limiter used on the HD-8 Series V can best be described as a resettable shear pin. The torque
limiter is set high enough to minimize nuisance releases but low enough to protect the driveline and rotor from damage
due to excessive loads. Bumping the clutch when engaging the rotor with this type of torque limiter can cause nuisance
releases also.
The clutch should be engaged smoothly and quickly to avoid releasing the torque limiter and minimize heating in the
clutch plates. Engage the clutch as you would engage the clutch in a heavy truck when starting from a dead stop.
When the torque limiter releases due to an overload, proceed with the following steps:
1. Throttle the engine to idle speed and release the clutch.
2. Unpin and raise the tub platform. Insert the platform safety stop.
3. Shut the engine down and remove the key.
4. Remove material that caused torque limiter to release.
5. Identify and align the index marks on the torque limiter.
6. Engage the safety element pins by tapping on them with a soft face mallet or a wood block.
7. Store the platform safety stop, lower the platform, and install the lock pin.
8. Start the rotor by engaging the clutch smoothly and quickly.
9. Throttle the engine to operating speed and resume grinding.
