DRIVING BELTS
The main drive to both rear roller and cassette is via hard wearing TBA poly-V type belts
which provide for smooth trouble free operation. To ensure the best performance the
following instructions should be carefully followed.
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 'defl ection' method.
NOTE
"Belts will be suffi ciently tensioned if the defl ection force applied at mid span to produce a defl ection 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 defl ection under moderate fi nger pressure on the non tensioner side.
If fi tting new belts it is advisable to observe the drive for the fi 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.
FOR BELT DETAILS, REF. 1.02 (Pg. 19)
Do not overtighten belts as this may cause excessive wear on the dog clutch.
