Pressure Relief/Air Bleed Assembly.18. The relief spring in each pump head is specificfor each application (Under no circumstancesshould any other spring be used in this assembly).19. To re-assemble pressure relief valve, insertpoppet/air bleed assembly into stem. Be sure itis centered and properly located onto seat.Insert spring and screw, making sure to returnthe screw to its original location. As noted earlierthe final setting of the pressure relief valveis covered in Operation, Section 3. Be sure toinstall protection cap, item 222/247 prior toinstallation.20. To access replenishment valve (Figure 9 &11), remove rear support plate, item 251 (sizeB only). To remove valve, tap lightly with a softrod through plunger bore on back side of valve.Figure 11. Replenishment Valve Assembly.21. The face of the valve, item 228/255 should besecured to the spool (item 225/252) via a pressfit. The spool should move freely in the valveand easily return to forward position via a conicalspring (item 227/254). See Figure 11.22. When action of valve is not smooth, replacementof entire assembly is necessary.23. O-rings should not be reused. Remove old o-rings carefully. Ensure there are no sharpedges on exterior of valve body.24. Lubricate new o-rings with hydraulic oil andcarefully install. Place plunger housing face upon firm table. Generously lubricate valve boreand set valve squarely into opening. Rotatevalve until one hole in valve body (Figure 12) isaligned with hole in plunger body (Figure 13)and press valve into plunger housing.17
