Clutch linkage
All Models
Lubricate the clutch linkage mechanism, cotter pins, clevis pins and levers, with engine oil
every 500 hours of operation.
DO NOT OVeRgReASe!
Lubricate sufficiently but sparingly. Excess oil can splash or drip onto the friction plates, causing
clutch slippage that may result in clutch failure.
Clutch Adjustment
Note: New power take-offs must have clutch adjustment checked before being placed into
service and after the first 8-10 hours of operation. This includes any power take-offs with new
friction plates. New plates have a wear in period and the clutch may require several adjustments
before the new plates are worn in.
After wear in, clutch adjustment should be checked regularly. Heavy duty applications (rock
crushers, etc.,) which have frequent engagements, numerous engagements in an operating day
or relatively long periods of slip require more frequent readjustment than light duty applications.
Adjust the clutch BEFORE it overheats, does not pull, or the operating lever jumps from the
engaged position. These symptoms are indications that clutch adjustment is required.
Adjustment measurements are made by fitting a torque wrench with a 1 1/2" socket over the
hex end located at the bottom of the hand lever. Grasp only the torque wrench when making
measurements.
To Adjust The Clutch:
1. Disconnect any power engagement devices from the operating shaft if so equipped.
