Rotary R.E. Union (Sizes 1/4" to 1-1/4")
Maintenance and Overhaul
• Remove bolts and washers (4) which allow for the removal of the adapter (5) and body (11). • Remove the bellows subassembly and the gasket of the seal kit (6). • Remove locking screws and unscrew the carbon subassembly (R.H. thread) of the seal kit (6). • Remove the spacer (7). • Thoroughly clean and check the ball bearing kit (9). Re-lubricate using an approved grease. If there is any doubt about the bearing condition, replace it by removing circlip (8) and then pressing-off the bearing kit. • If the adapter (5) is Type R.S., remove the locking screw (3), unscrew the locking ring (1) and remove the C/T bearing (2). • Replace seal kit (6), bearing kit (9) and if Type R.S., C/T Bearing (2). Handle the seal kit with care to avoid damaging the 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.
