| Assembling | ||
7 | Install the integrated bearing shaft (3) in the housing (4). | Press the bearing (3) supporting on the outside race. | |
| |||
8 | Install the snap-ring (2) in the housing (4). | ||
Danger! | Risk of injury on skin and eyes by handling heated or incandescent objects | Use protective gloves, clothes and glasses. | |
9 | Uniformly heat up the flange (1). | Maximum temperature 80°C. | |
10 | Install under pressure the flange (1) on shaft (3). | The flange must face the axle end. In order not to damage the bearing, press-on the flange with the shaft resting on a flat surface. | |
11 | Install a new sliding seal (5) with the driver (12). | Ensure the perfect seating of the seal, on the shaft and in the pump housing. | |
