(E) HP7 and HP8 Aluminum Housings. (6) Guide With Diameter (B) Down. (9) Shim (For HP7 housing only).
Install bolt (1), washer (2), and cap (3) to hold the staking tool together as a unit.Note: Install the bolt finger tight.
Install the proper sleeve bearing (F) over diameter (A) or (B), depending on housing style. The sleeve bearing should be seated against the shoulder of guide (6) .
When positioning the pump/motor housing (E) in a hydraulic press, make sure it is level. If the sleeve bearing bore is not aligned correctly, the housing and/or the sleeve bearing can be damaged beyond repair when the sleeve bearing is pressed into the housing.
Carefully position the pump or motor housing in a hydraulic press capable of attaining 4.5 t (5 tons) of force.
Place the staking tool and sleeve bearing (F) on housing (E) and align the sleeve bearing to the housing bore.
When positioning tooling on housing (E) make sure staking legs (5) are in alignment with staking grooves (10) in the housing. If they are not aligned, the housing will be damaged.

Remove bolt (1) and washer (2) from the top of the staking tool guide stem.
Use hydraulic press (12) to push the staking tool and sleeve bearing (F) into the housing bore just until sleeve (7) contacts the surface of pump or motor housing (E). Do not apply more force than is required.Note: The hydraulic press must not contact the upper guide stem during this step. The guide stem should be recessed in the cap, as shown.
