1.Tilt unit up onto its’ nose ( resting vertically on handle, ref# 130). See Fig. 1.

2.Remove the eight bolts ( ref# 17) securing the paint head ( ref# 18) to the hydraulic head ( ref# 53).

3.Place rags around the cylinder area to absorb hydraulic oil which will leak while performing step 4.

4.Remove the six bolts ( ref# 59 ) securing the crossblock/cylinder/hydraulic head. Bolts are accessed from the underside of crossblock.

5.Remove hydraulic head ( ref# 53) to work bench.

6.Remove old, broken or damaged insert ( ref# 55).

NOTE: Insert should have no movement, when properly installed. If it is spinning or able to move back and forth, but has not come completely free of the hydraulic head, it may be possible to re-tighten using the same installation instructions to follow. See steps 8 – 10.

7.Place new insert into the hydraulic head. See fig. 2. Insert will protrude through the hydraulic head by approximately 1/8”. To affix the insert the extra material of the insert must be flared to secure to the hydraulic head.

8.Position a steel ball on the front and back of the insert. See figure 3.

9.Position this assembly in the jaws of a vise.

10.Slowly close the vise jaws. The vise acts as a press and the ball will cause the extra insert material to flair around the head. Continue closing vise until the insert is tight and can no longer be rotated or spin in the hydraulic head. Over tightening can create cracks or splits in the flange/flare, leading to repeat failures. Do Not over tighten.

11.Re-assemble pump, in the reverse order of removal. Torque all bolts to 30 foot pounds.

12.Once the repairs are completed , return unit to horizontal position, replenish lost oil and purge per instructions on page 19.
