1. Disconnect all plumbing.
2. Remove the six socket head screws from the manifold. Remove the outer screws first, then the inner screw.
3. Using a soft mallet, tap the back side of the Discharge Manifold from alternate sides to maintain alignment and
avoid damage to the plungers
4. Grasp the Discharge Manifold from the underside and gradually lift manifold while you pull away from the
Crankcase.
5. The Adapter/Spacers may stay with either the Discharge or Inlet Manifold. By inserting two opposing screwdrivers
between Spacer and manifold, you can easily remove them from the Discharge Manifold. If they stay in the
Inlet Manifold, gently work them up and down as you pull away from the Inlet Manifold.
6. The Valve Assemblies are in the Discharge Manifold ports and will fall out when manifold is turned over.
Disassembly of the Seal Assembly
Tools Required: 3/8” Drive Ratchet; 6mm Hex Socket; Packing Extractor; and Colette.
1. Remove the Inlet Valve Assembly from the exposed plunger rod ends, including Cotter pin, Nut, Washer, Spring,
Spacer and Inlet Valve.
2. Grasp the Inlet Manifold from the front and underside and pull to remove from Plunger Rods.
3. Carefully examine backside of Low Pressure Seal before removing from manifold as it will be damaged during
removal. If worn, insert screwdriver into I.D. of seal and pry out. Exercise caution to avoid damage to the Inlet
Manifold.
4. Press ceramic Plunger with thumb or soft tool from backside of Inlet Manifold. (The High Pressure Seal may
stay with the plungers or remain in the Inlet Manifold. If on the plungers, slide off by hand. If in the manifold,
use reverse pliers to remove.)
5. Remove Seal Retainers from Crankcase by grasping tab with pliers and pulling out.
6. Examine Crankcase Oil Seal to determine if Crankcase servicing is needed.
7. Examine Ceramic Plunger, Low Pressure Seals, V-Packings for scoring, cracks, and wear and replace if needed.
Reassembly of Seal Assembly
1. Examine Seal Retainers and replace if worn or damaged. Install on Plunger Rod and press into Crankcase with
tab out.
2. Place Inlet Manifold on work surface with Crankcase Side up.
3. Lubricate new Low Pressure Seals and press into position with garter spring down. Be certain the seal is seated
squarely on the shoulder on the inlet manifold chamber.
4. Place the inlet Manifold on work surface with Crankcase side down (Larger ID ports up).
5. Carefully examine the Plungers for scoring or cracks and replace if worn.
6. Lubricate Ceramic Plungers and new High Pressure Seals. Press the plunger into the seal and position seal in
middle of plunger. NOTE: Place the deeper recessed end of the plunger into the seal from the metal backside.
7. Insert the Plungers into the manifold ports. Press into position using the larger I.D. end of Discharge Valve
Spacer. Examine the O-Ring and Back-up-ring under the Sleeve for cuts or wear and replace. Examine the
Barrier Slinger for wear and replace as needed. Install the Barrier Slinger with the concave side facing away
from the Crankcase. Lubricate the Plunger Rod O-Ring to avoid cutting during installation. Install the Back-up-ring
first then the O-Ring into the groove on the Plunger Rod. Install the Sleeve with the tapered end facing out.
Gently press towards the Plunger Rod shoulder until flush with the Barrier Slinger.
8. Carefully install Inlet Manifold over Plunger Rod ends and slowly press into Crankcase.
9. Examine Inlet Valve and replace if worn. Inlet valves cannot be reversed if worn. The SS Inlet Valves may be
lapped if not badly worn. Install the SS Inlet Valves with square edges towards the plungers (round edges
towards the discharge). Install the Nylon Inlet Valve with ridged side towards the discharge.
10. Examine Spacers for wear and replace as needed. Install Spacer on each Plunger Rod with smaller O.D.
towards inlet valve.
11. Examine Springs for damage or fatigue and replace as needed. Place on Plunger Rods.
12. Install Washers next with concave side towards Inlet Manifold.
13. Install Nuts and torque to 55 in. lbs. / 4 ft. lbs. / 4 Nm.
