Ring and stationary ring face grinding

1 ) Remove the snap ring , after grinding, rough first study , after lapping , conditions can be polished .
2 ) coarse grinding , the choice of 80 ~ 160 # grit abrasive , first rubbed machining marks . These can then be abrasive grinding 160 # , so finish to meet the design requirements. Carbide or ceramic ring is required after grinding machine polishing with a polishing . The intensity of polishing machine can be used M28 ~ M5 boron carbide . Polished to a mirror . Ceramic ring available after the M5 agate powder grinding ,plastic truck seals polishing with chromium oxide .
3 ) graphite-filled PTFE stationary ring , because the soft material , can be used kerosene, gasoline or water lapping , without adding abrasives. In the running-in process can also self-development , so finish requirements are not too high .
4 ) milling method, and a grinding machine can grind the grinding machine , grinding machine can not on the use of glass -eight manual polishing method .

Sleeve check
1 ) Remove the rear hub overhaul inspection corrosion and wear , and if rust or wear out relatively minor , can be used fine sandpaper and then , if severe corrosion or worn plating method can be processed or replacement bushings .

Seals
1 ) the use of time after a ring , the majority of cases, loss of elasticity or aging , in general, need to replace the ring .

Spring
A ) If the spring rust is not serious, to preserve the flexibility, time to replace it. If corrosion is more serious or elastic reduced a lot, you will need to be replaced with new springs.
2 ) of a mechanical bolt security seals cartridge assembly , to clean cartridge and check for wear or deformation of the groove , so that correction repaired, re- slotted or replaced.
3 ) After mechanical seals repair , re- assembly, the assembly after the same pressure test , and then put into normal operation.
