METHOD: 1. SET THE DEFLECTION DISTANCE ON THE LOWER SCALE OF THE TENSION
GAUGE SO THAT THE UNDERSIDE OF THE 'O'-RING EQUALS THE 'h' VALUE
GIVEN IN THE TABLE BELOW
2. ENSURE THAT THE DEFLECTION FORCE SCALE IS ZERO'D BY PUSHING THE UPPER 'O'-RING ALL THE WAY DOWN
3. PLACE THE TENSION GAUGE IN THE CENTRE OF THE BELT SPAN AS
SHOWN IN THE DIAGRAM LEFT
4. PRESS DOWNWARDS ON THE RUBBER BUFFER, DEFLECTING THE BELT
UNTIL THE UNDERSIDE OF THE LOWER O'-RING IS LEVEL WITH THE BELT
BEHIND (USE A STRAIGHT EDGE IF THERE IS ONLY 1 BELT)
5. TAKE THE READING FROM THE DEFLECTION SCALE OF THE TENSION
METER (READ AT THE LOWER EDGE OF THE 'O'-RING) & COMPARE THIS
VALUE WITH THAT GIVEN IN THE TABLE BELOW
6. TIGHTEN OR LOOSEN BELTS AS REQUIRED FOLLOWING PROCEDURE
GIVEN IN THE OPERATOR'S MANUAL
TENSION GAUGES ARE AVAILABLE FROM TIMBERWOLF SPARES, QUOTING
PART No. 18091
TIPS ON BELT TIGHTENING: A) THERE WILL NORMALLY BE A RAPID DROP IN TENSION DURING
THE RUN-IN PERIOD FOR NEW BELTS. WHEN NEW BELTS ARE
FITTED, CHECK THE TENSION EVERY 2-3 HOURS & ADJUST UNTIL
THE TENSION REMAINS CONSTANT B) THE BEST TENSION FOR V-BELT DRIVES IS THE LOWEST
TENSION AT WHICH THE BELTS DO NOT SLIP OR RATCHET UNDER
THE HIGHEST LOAD CONDITION
C) TOO MUCH TENSION SHORTENS BELT & BEARING LIFE
D) TOO LITTLE TENSION WILL AFFECT THE PERFORMANCE OF
YOUR MACHINE ESPECIALLY IN RESPECT OF NO-STRESS DEVICES
E) ENSURE THAT BELT DRIVES ARE KEPT FREE OF ANY
FOREIGN MATERIALS
F) IF A BELT SLIPS - TIGHTEN IT!
