BARECO – PTO CLUTCH 8″ (100HP) H/D BLUE

BARECO – PTO CLUTCH 8″ (100HP) H/D BLUE

Bare Co. blue-torque heavy-duty, high-capacity friction type safety clutch. The design of the blue-torque clutch offers increased power transmission in a smaller diameter clutch. Ideal for use in agricultural applications including slashers, chaser-bins and other PTO powered machinery.

Blue-torque friction clutches come supplied with heavy-duty dark blue springs. These springs identify the clutch as a high capacity blue-torque model and offer increased performance over standard clutches fitted with gold compression springs.

When delivered from the factory, friction clutches are normally set to their rated torque settings. This is achieved by tensioning the clutch springs to their maximum compressed length. Compressing the springs beyond these lengths will cause damage to the clutch

This is a general guide on how to correctly set a Bare Co. friction clutch

Step Action Specification
1. Intial Spring Compression Standard Duty (Sliver or Gold Springs) All sizes – Compress fully then back off 2 turns.
Blue Torque (Blue Springs) 150mm (6″) Clutch – Compress spring to 28mm overall length
Blue Torque (Blue Springs) 200mm (8″) Clutch – Compress spring to 31mm overall length
2. Operate Clutch Run machine for approximate 10 minutes
3. Check Clutch Springs Set Correctly – Warm to touch approx 45C (Like a warm cup of tea)
Springs Overtight – Cool to touch, springs too tight, back off  each spring 1/4 turn and retest
Springs Loose – Hot to touch, over 60C (Excessive slipping) tighten spring 1/4 turn and retest
4 Storage When clutch is not in use, back off spring nuts completely and remove all tension from springs
5. Maintainence At 6 Months, back off to polish discs.

 

How to free up the clutch after a period of storage:

As outlined in the instructions on most implements, the slip clutch can seize if left for long periods without use, or left outside in the elements. The best way to free up a slip clutch is to loosen all the bolts that hold the spring tension on the friction plates (so they are quite loose), then run the machine with it either jammed so it cannot move, or put into heavy work, to slip the clutch. The clutch only needs to be slipped for 30 seconds to a minute to clean up the surfaces. Alternatively dismantle the clutch and clean it.
