Maintenance and Overhaul
- Remove the locking screw (4) which allows for the removal of locking ring (10).
- Remove the spindle (9) complete with bearing kit (8), circlip (7) and carbon subassembly of seal kit (5).
- Remove spacer (6), seal subassembly and gasket of seal kit (5) from the body (3).
- If type R.S., unscrew end fitting (1-R.S.) from the body, remove and replace the C/T Bearing (2).
- Hold spindle (9) in a vice, remove locking screws to enable carbon subassembly of seal kit (5) to be unscrewed, then remove gasket.
- Remove circlip (7) and press off bearing kit (8) from spindle (9).
- Discard and replace seal kit (5) and bearing kit (8). Handle seal kits with care to avoid damaging the precision lapped seal faces.
- Thoroughly clean all parts before reassembly (which is virtually the reverse of the above steps).
- After reassembly, follow the recommended installation procedures and allow for a suitable run-in period to ensure the seals are working correctly before refitting to the machine.
