REPLACING VALVE SPRING UNIT

Kit #3-007

Parts Needed: 3 Tip Washers, 1 Valve Seat, 1 Valve Ball Holder, 1 Valve Spring Unit

1.Repeat dismantling procedure as outlined above under Steps 1 through 3.

2.Unscrew nut, remove retainer with retainer pins and push shaft of the valve spring unit out of the gun head.

3.Clean gun head bore with solvent and small brush. Do not use any sharp objects to scrape away dried paint, as they would cause leakage around the seal.

1/8 turn, as doing so can break the valve spring unit shaft. Continue reassembly and adjustment as described above.

FLUID PUMP

NOTE: Check the Troubleshooting

Chart on page 14 before disassembling the Fluid Pump.

FLUID PUMP DISCONNECT

1.Flush out the material you are spraying, if possible.

2.Follow the "Pressure Relief Procedure" on page 3.

3.Remove the suction tube assembly from the paint pump by unscrewing the suction nut. Disconnect sensor assembly by holding sensor with 7/8" wrench and unscrewing swivel connector with an 11/16" wrench.

4.Move the piston rod to its lowest stroke position by rotating the motor fan or by cycling rod to lowest position.

5.Unscrew the two screw from cover assembly.

6.Remove retaining ring. Slide sleeve down off crosshead assembly Remove pin out of crosshead allowing removal of fluid pump from unit.

FLUID PUMP REINSTALLATION

1.Loosen packing nut and extend piston rod to its upper position in paint pump. Slip sleeve and retaining ring over piston rod.

2.Push piston rod up into crosshead assembly and align holes. Insert pin through crosshead assembly and piston. Slip sleeve up over pin and insert retaining spring into groove on crosshead assembly.

3.Secure paint pump to cover assembly by two screws, up through tube spacers and screw into cover assembly.

4.Tighten screws evenly and alternating to 20 ft. lbs.

5.Reassemble the Lower Check Valve assembly by placing the Suction Seat Assembly, O-ring, ball and retainer in the suction nut and screw nut onto pump body.

6.Reconnect sensor assembly to fluid pump. Hold sensor with 7/8" wrench while tightening swivel connector.

7.Start the pump and operate slowly to check the Piston Rod for binding. Adjust screws holding pump assembly to cover assembly if necessary to eliminate binding.

8.Tighten the packing nut until resistance is felt against the belleville springs, then 1/2 turn more CW (approximately three threads showing). Fill the wet cup of Packing Nut 1/3 full of Throat Seal Oil (TSO).

9.Run unit at full pressure for several minutes, release pressure and repeat step 4. Readjust packing nut according to paragraph above.

GEAR AND PUMP ASSEMBLY

Do not operate

! WARNING machine without cover guard in place.

1. Disconnect Fluid Pump as instructed in Fluid Pump Disconnect.

2. Place piston in block (Tool Part No.

331-195) with the 3/8" dowel pin (Tool Part No. 331-196) and hold in vise. See diagram on page 21.

NOTE: DO NOT use smaller diameter pin than Part No. 331-196 to hold piston.

3.Place a 1/4" allen wrench into bottom of piston. Unscrew retainer from piston. Clean all parts and inspect them carefully for wear and damage. Inspect the surface of piston and seat for wear or damage. Replace these parts if needed. If repacking pump, replace ball and O-ring with new parts from Packing Kit.

4.Lay unit on its back and disassemble gearbox.

5.Inspect bearings and Crosshead Assembly Gearcrank and sleeve bearing inside cover assembly for wear or damage.
