1.Remove cap (Item 10). Remove valve adjuster (Item 9), spring (Item 8), and ball (Item 7).

2.Remove o-ring (Item 32) from cap.

3.Inspect ball for burrs or roughness. Inspect relief valve bore and seat in bearing plate (Item 28).

4.Inspect spring for damage.

5.Clean and dry all parts. Apply hydraulic oil to parts. Install ball, spring and valve adjuster.

6.Install new o-ring on cap and install cap.

7.Before operating the machine, check steering relief pressure and adjust to 800 psi. To adjust, remove cap, turn adjuster clockwise to increase pressure and coun- terclockwise decrease pressure. (See Test Hook Up No. 5, Steering Pump Flow and Steering Pump Relief Set- ting in the Testing section of this chapter.)

1.Plug ports and wash exterior of pump with mineral spirits or solvent. Make sure parts and work area are clean.

2.Draw a line across the seam areas on the pump case with a scribe or marker to ensure proper reassembly.

IMPORTANT: Use caution when using a vise to avoid distorting any parts.

3.Secure the flange end of the pump (Item 15) in a vise with the drive shaft (Item 20) pointing down.

4.Remove the four locknuts (Item 1) and lockwashers (Item 2).

5.Put your hand on the pump case and gently tap the pump case with a soft face hammer to loosen the pump sections. Be careful not to drop parts or disengage gear mesh.

6.Before removing each gear set, apply marking dye to mating teeth to retain “timing” when reassembling.
