TIMBERWOLF V-BELT TENSIONING DATA TABLE

1. SET THE DEFLECTION DISTANCE ON THE LOWER SCALE OF THE TENSION GUAGE

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 GUAGE 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 GUAGES ARE AVAILABLE FROM TIMBERWOLF SPARES, QUOTING PART No. 18091

New belt

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!
