The preferred method of removing or installing the bushing is with tool J 43771 and a press. If a press is not available use J 43771 and J 8092.

6. Press or drive the bushing (2) from the pump body (1).
7. Clean the bushing bore of all residue. All of the parts must be dry before installing the bushing.
