For dismounting, the kit comprises two centre screws, five sets of three puller arms each made of high-tensile alloy steel, a puller handle, a slide hammer and seven support rings to support the bearing with an interference fit on the outer-ring only. The arms are provided with color codes for an easy identification. For mounting, the kit consists of 21 impact rings, two high-strength aluminium sleeves and a dead-blow hammer with nylon faces. The rings as wll as the impact surfaces are made of a super-tough acetal resin, giving high mechanical strength and impact fatigue resistance at a very low weight. The fibreglass handle, with comfortable grip for good handling, absorbs shock and vibration. All parts are clearly arranged in a practical transport case. A selection chart and instructing pictures are included in each unit.
Operating Instructions
Dismounting ball bearings on a shaft and in a housing
