RELIEF VALVE ASSEMBLY

(E1-2 thru E1-82 Models)

1. Check the valve body O-ring for damage or wear and replace, if necessary.
2. Position the valve body O-ring in its groove in the valve body. If necessary, use a small amount of light adhesive to keep

the O-ring properly positioned.

3. Position the spring and poppet inside the valve body.
4. Determine which pocket in the head is aligned with the discharge port. The relief-valve poppet must be positioned on the

discharge pocket for the valve to function correctly.

5. Position the valve body/spring/poppet onto the pump head with the poppet over the discharge pocket and loosely

assemble the valve-body screws.

6. Tighten the screws in an alternating pattern until the valve body is fully contacting the head. Torque the screw to their final

values:
a. 10 mm (3/8”) screws: 54 N•m (40 ft-lb)
b. 13 mm (1/2”) screws: 88 N•m (65 ft-lb)
