ADJUSTMENT OF THE CLUTCH LINKAGE
Make sure the engine is OFF and remove the negative battery cable to ensure the unit can not accidently be started.
Remove the spring from the throwout arm. (See PIC# 1) An accurate measure of the arm tension CAN NOT be
made with the spring attached.
With the clutch in the engaged position (the PTO is engaged when the PTO handle is pointing straight up on the
LCT600 and LCT6000 and pointing out to the side (3 o'clock) on the LCT60C, LCT650 and SCL800TM) adjust
the nut (See PIC# 2) against the "rocker ball" until a 1/8" gap between the nut and rocker ball is visible (
See PIC# 3).
If available, use the special 1/8" gauge tool to slip between the nut and rocker ball. With the proper adjustment the
gauge should slide between the nut and rocker ball with a slight amount of pressure. (See PIC# 4)
Move the adjustment nut to create the 1/8" gap.
Re-install the return spring.
Place the handle in the disengaged position. Check to make sure that the PTO output shaft turns freely.

Rotating Shafts, pulleys, and moving belts can cause severe injury or can be fatal. The
engine and driven unit MUST be completely stopped before any adjustments or work is at-
temped to the engine, driven unit, or the PTO clutch itself.
The clutch linkage should be checked after the first 15 hours of operation and every 40 hours there after. An im
-
properly adjusted clutch can result in premature wear to the clutch disc, flywheel and the throwout bearing and
will
void the warranty on the clutch and PTO.
