The torque selector dial shown in Figure 4 is a standard feature on all

Standard Model S Trig-O Matic clutches. Each clutch is individually

calibrated to specific torque values. The housing has two milled

marks indicating minimum and maximum torque. In addition, these

values are stamped on the housing adjacent to each mill mark. To

adjust the torque, loosen the “lock screw”, turn the torque adjusting

screw (stamped #9) until it is flush with the milled depth and the red

scribed lines match the required output position. Additional marks

can be indicated upon request.

Maximum Torque Limit Stop

A maximum torque limit stop is supplied to prevent clutch lockup.

In conjunction with a torque selector dial, the maximum value

indicated by the deepest milled mark can not be exceeded.

Grease Pack Fittings

Grease pack fittings are supplied countersunk into the clutch

housing to pack the clutch cavity, preventing corrosion. This feature

is especially suitable for outdoor or washdown service.
