GEAR PUMP 1.2
6. Procedure
1. Clamp the unit in a vice from the flange side
(fig. C4348). Make sure the vice jaws are clean and
have smooth surfaces to prevent damage to the
pump. Caution must be used when using a vice to
avoid distorting any parts or damaging the mounting
pilot.
2. Use a Allen head socket wrench to loosen the
bolts on the cover assembly (fig. C4349). Next
completely unscrew the bolts and remove them.
Inspect the threads for damage (fig. C4350).
3. Slowly remove the cover assembly (fig. C4351).
Note, some units have a shaft seal and others do not.
Should your unit have the shaft seal, be careful not to
damage it when removing the cover assembly.
