Maintaining Your Power Take-Off
Keeping your twin disc over center clutch in good operating condition is easy if you know
these guidelines. This Tech Tip will show you how to check your clutch for adjustment, how
to adjust it, and how to keep it lubricated.
When to Adjust Your Clutch
The key to maintaining your clutch is knowing when to adjust it. Monitor the force
necessary to engage your clutch. If the pressure requires to engage it drops 10-15%, your
facings are wearing and your PTO needs adjustment.

Recently, service people have developed an easy method to measure engagement force.
They weld a socket on to one end of the cross shaft and use a torque wrench. This
technique is so simple that it can be done as part of your daily maintenance. The chart
below tells you when it is time to adjust your PTO.
Clutch Size Engagement Force Must Adjust At:
8 ” 65 - 72 ft. lbs. 55 ft. lbs.
10” 101 - 108 ft. lbs. 85 ft. lbs.
11 ½” 108 – 115 ft. lbs. 91 ft. lbs.
How to Adjust Your Clutch
Here are the steps to take: Disengage the clutch, remove the inspection plate and rotate
the clutch to gain access to the adjusting ring lock. Then adjust to obtain the proper
handle engagement force. When done, reposition the locking finger in a slot and tighten
the adjustment lock bolt.
Lubricate Your Clutch
Use lithium base #2 grease prior to installation of your PTO. Grease the release bearings
(if not sealed), the main bearings (rotate shaft by hand until the grease comes out), and
the cross shaft. Once the PTO is installed, follow this schedule below.
