To reduce the possibility of costly damage to the rod (1) and cylinder (7), first place the cylinder on a soft block of wood. Always use a rubber mallet or an arbor press to drive the rod (1) into the cylinder

(7). Never use a hammer to drive the rod.

5.

Use an arbor press to reinstall the rod (1) into the cylinder (7), as follows. (The cylinder is symmetrical, so either end may face up.) Lubricate the piston seals (P). With the piston end facing down, lower the rod into the cylinder. Start the piston into the cylinder as much as possible, then drive the rod and piston the rest of the way into the cylinder with the arbor press.

6.

Place the cylinder (7) on the intake housing (15).

Tap on the top of the displacement rod (1) with a rubber mallet, to seat the cylinder.

7.

Lubricate the seal (6) and install it in the bottom of the outlet housing (17). Set the outlet housing on top of the cylinder (7). Apply thread lubricant to the six long cap screws (18). Install the cap screws through the outlet housing (17) and thread them loosely by hand into the intake housing (15). Tighten the cap screws oppositely and evenly, then torque to 258 +/- 41 N•m (190 +/- 30 ft-lb).

8.

Install the bleeder valve plug (23). The plug has two sets of threads. Be sure to screw the plug fully into the valve body (31). Torque the plug to 34 +/- 3 N•m

(25 +/- 2 ft-lb).

9.
