Fitting and use
Mount the idler on a bolt that matches the bore, or the reduction bush where one is fitted, and clamp through the bush or inner ring only so the pulley rim turns freely on the bearing.
The bearing is sealed and lubricated at the factory. Keep water, grit and solvents away from the seals, and replace the idler if the bearing runs rough or noisy.
Choosing the right option
Match the idler to the belt it runs on (belt type), then the outside diameter, the bore or bolt size, and the width the belt needs. The flanges keep the belt on the pulley, so the face width needs to suit the belt.
The model codes and dimensions for each size are in the sizes table. If you have the old idler, match its model code or measure the outside diameter, bore and width.
