Reassembly

Refer to Fig. 8 for reassembly.

1.Place an 8 mm (5/16 in.) dia. brass rod lengthwise in a vise. Install a new piston seal (14*) on the piston seat (15). Apply thread lubricant to the threads of the piston guide (12). Place the piston guide (12) securely on the brass rod. Using a 22 mm crow’s-foot, screw the piston seat (15) into the piston guide. Torque to 35–41 N.m (26–30 ft-lb).

2.If it was necessary to remove the priming piston rod (21) from the piston (13), apply thread lubricant to the female threads of the piston. Place the flats of the piston (13) in a vise. Hold the flats of the rod with an 8 mm wrench, and screw the rod into the piston. Torque to 35-41 N.m (26-30 ft-lb). Be careful not to create burrs on the flats of the rod.

3.Use a vise with soft jaws to hold the flats of the displacement rod (1). Install the assembled piston guide/seat on the piston (13). Apply thread lubri- cant to the female threads of the piston, and screw the piston assembly onto the rod, using a 15 mm wrench on the piston flats. Torque to 35-41 N.m

(26-30 ft-lb). There will be a small gap between the top of the piston (13) and the shoulder of the rod

(1).

4.Place the outlet housing (9) in a vise. If the bleeder valve housing (BB) was removed, apply PTFE tape to the threads and reinstall it in the outlet housing (9), making sure the bleed hole faces toward the bottom of the outlet housing. Then screw the valve plug (AA) fully into the valve housing (BB).

NOTE: The bleeder valve plug (AA) has two sets of threads. When reassembling, be sure the plug is fully screwed into the valve housing (BB).

NOTE: It is not ordinarily necessary to remove the outlet nipple (7) and o-ring (8*). However, if they were replaced because of damage, lubricate the o-ring (8*) and place it on the nipple (7). Screw the nipple into the outlet housing (9). Torque to 60-84 N.m (44–62 ft-lb).
