DISASSEMBLY
1.
See Figure 12
Back off maximum volume screw or handwheel to full displacement. Remove maximum volume assembly.
2. Remove bolts holding cap to pump.
3. Remove isolation valve (29) from block (28). Remove plug (15) and attached parts. Remove spring (11) and spool (18).
4. Remove adjusting plug (2) and attached parts. Remove seal piston (5). Note: a 10-24 screw may be used to assist in
pulling the piston. Remove spring (7) and cone (8).
5. Do not remove sleeve in body (1). Sleeve is pressed into cap and finished to size. If sleeve or cap is worn, replace the
cap-sleeve assembly (1).
6. Examine seat (10) for wear. Do not remove unless damaged.
ASSEMBLY
See page 26 for tightening torque on plugs
1. Install Avseal plugs (9) and.047”, 1,19 mm. orifice (19) in body.
2. Press seat (10) into bore squarely against shoulder in bore.
3. Install plug (12) and spool (18) into bore as shown. Install spring (11) over end of spool. Install O-ring (6) on seal pis-
ton(16). Lubricate and install into plug (15). Install plug (15) into cap. Install screw (3), nut (4) and cover (17).
4. Install O-ring (6) on seal piston (5).
5. Lubricate O-ring and install cone (8), spring (7) and seal piston into bore in cap (1), being careful that cone enters seat (10).
Install remaining parts in body (1).
6. Install O-rings (29-a) and (29-b) on valve (29). See Figure 13, page 40. Observe that backup ring on inside groove is
toward the outside, the one on the middle groove is toward the inside, and the one on the outside groove is toward the
outside. Lubricate and install valve (29) in block (28), being careful to avoid damaging the O-rings. Torque to 50 lb.• ft.,
67,8 Nm.
7. For the P110 only, install O-ring (32) on adapter (35). Install adapter in block (28). Install plug (31) in adapter (35). For the
P07 only, install O-ring (32) on plug (31). Install plug (31) in block (28).
8. Note proper location for cap on pump (page 24). Install O-rings on interface between cap and pump control pad. Install O-
rings (26) in block (28).
9. Install on pump control pad, guiding the control piston into the bore. Install maximum volume stop parts.
10. Torque mounting bolts to 75 lb.• ft., 102 Nm.
