8.The pressure rings (item 30) can now be removed by pulling straight out. Inspect and clean manifold (29) and pressure ring. Replace if necessary. From the front of the pump reinstall pressure rings into manifold (29) with grooved side towards front of manifold. Install new v-sleeves (31 or 50), with grooved sides towards front of pump. For P46W-HK & P46HT pumps, install high temperature seal (31A) with grooved sides towards front of pump. Replace the support rings (32) and pressure springs (33) into manifold (29). Install valve assembly (34-40) into manifold (29). Reinstall manifold plugs (43) and torque plugs to 52 ft.-lbs.

9.The rear V-sleeve housing (48) may be removed by prying evenly outward with a flat screwdriver. After slipping housing over plunger, inspect seals (50) and O-ring (49) and replace as necessary.

10.Inspect ceramic plunger (24A) tips for wear. If necessary, replacement of the ceramic plungers may be accomplished by removing the plunger bolt assemblies (24B and 24C) with a 13mm wrench. Ceramic plungers should now slide off the stainless steel plunger base (22). Excessive resistance to plunger removal may be overcome by heating the stainless steel plunger base. This will melt any excess loc-tite beneath the ceramic plunger allowing easy removal.

11.Replace copper ring (24C) onto plunger bolt (24B). Slide plunger bolt assembly into ceramic plunger (24A). Apply a light film of loc-tite to plunger bolt threads and place plunger assembly onto stainless steel plunger base (22) and tighten to 105in.-lbs.

12.To replace plunger oil seals (26), proceed to “Gear End Disassembly” section below. Otherwise, continue as de- scribed below.

13.Before replacing pump manifold (29), first rotate crankshaft (18) until two outside plungers (24A) extend evenly forward. Next lubricate v-sleeves (50) in the rear v-sleeve housing (48) and slide housing over plungers. Lubricate ceramic plungers with a light film of oil. Carefully and evenly slide manifold over plungers and press manifold firmly against crankcase

(1). Replace manifold stud bolts (45), washers (47) and nut (46) and tighten to 35 ft.-lbs.
