The Primary Rear roller drive belt is shown in Fig 1.
This is a special Kevlar V belt design for clutching
applications. The Rear roller clutch pulley moves
into tension the belt via a control cable. The tension
in the cable can be adjusted as shown in Fig 1
[13mm spanner].
Under tensioning this belt will lead to slip and
cause rapid wear. Over tension will put excessive
stain on the belt and bearings.
The Secondary Rear roller drive belt is shown in Fig 2 (item1). This is a hard wearing poly-V belt. Belt tension is the single
most important factor necessary for long,
satisfactory service life of any belt drive.
Under-tensioning leads to belt slip causing rapid wear; over tensioning means excessive strain on belt and bearings.
Between these two extreme conditions is a reasonable range of tension within which the belt will operate. Belt tension can
be assessed by the ‘deÀection’ method.
CORRECTION CAN BE MADE BY ADJUSTMENT OF THE BELT TENSIONERS. REMOVE
THE DRIVING BELT COVER. THE BELT TENSIONERS ARE RETAINED IN A SLOTTED
HOLE ALLOWING ADJUSTMENT TO BE MADE ONCE THE HOLDING HEXAGON
HEADED BOLTS HAVE BEEN LOOSENED. WHEN ADJUSTED CORRECTLY THE
TENSIONERS SHOULD STILL ROTATE EASILY WITH FINGER PRESSURE. ENSURE THE
TENSIONER BOLTS ARE SECURE BEFORE REPLACING THE COVER.
NOTE
“Belts will be suf¿ciently tensioned if the deÀection force applied at mid span to produce a deÀection equal to 16mm per
meter of span distance falls between 5 and 9 Newtons per Rib” (TBA Belting).
In practical terms this relates to about 5mm of deÀection under moderate ¿nger pressure on the non tensioner side.
If ¿tting new belts it is advisable to observe the drive for the ¿rst 20-30 minutes. It may be necessary to make an
adjustment to compensate for the normal drop in tension during the run-in period.
