The Rear roller clutch pulley movesinto tension the belt via a control cable. The tensionin the cable can be adjusted as shown in Fig 1[13mm spanner].Under tensioning this belt will lead to slip andcause rapid wear. Over tension will put excessivestain 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 singlemost 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.
