Place a container under the manifold when removing the hose or port plug. 6. Apply PTFE tape to the threads of the drain valve (C), and then screw the valve into the adapter. 7. Open the tank shut-off valve, and then restore the melter to normal operation. Manifold on DuraBlue 4, 10, and 16 Manifold on VersaBlue and DuraBlue 25, 50, and 100

29 Instruction Sheet P/N A Pump Seal Kit - P/N (4.9 cc pump) and P/N (7.8 cc pump) 41 DURABLUE IS 15 02/04 This instruction sheet describes the procedure for replacing the pump seal on DuraBlue 4.9 and 7.8 cc gerotor pumps. Use service kit P/N for the 4.9 cc pump and use service kit P/N for the 7.8 cc pump. Flat-tip screwdriver 13 mm open-end wrench 6 mm hex key Retaining ring pliers Viton O-rings P/N (1) P/N (1) P/N (1) P/N (1) Remove the Drive Assembly 1. Allow the melter to heat up to Ready status. Refer to Starting the Melter, in section 4 of the melter product manual for information about ready status. 6. Remove the protective cover from the side of the pump. 2. For D4 melter, operate the melter until the tank is empty. For all other melters, close the tank shut-off valve (Position 2 is closed; position 1 is open). Retaining Ring (Internal) Washer 7. Remove the RTD and the heater from the pump body. Save the screws, washer, and the RTD retaining clip. Seal Key Pin 1 Retaining Rings (Crescent) Shaft 3. Switch the melter off. WARNING: Risk of electrocution! The control switch does not remove high-voltage power from the melter. Before opening the electrical compartment door, ensure that the local power disconnect switch is in the off position and locked. Failure to properly disconnect the power from the melter can result in personal injury, including death Remove the four M8 pump screws and matching washers that attach the pump to the bottom of the tank. Note: When reassembling the drive assembly to the tank, tighten the M8 pump screws to N m (12 13 ft-lb.). Parker lubricant Insertion Tool 4. Disconnect power to the melter at the local power disconnect switch. 5. Disconnect all hoses from the manifold. Continue

30 9. Disconnect the motor pigtail from its connection point underneath the melter, and then slide the drive assembly out of the chassis. Remove the Pump 1. Disassemble the manifold (A) and the motor assembly (B) from the pump (C). Save the four spacers that are between the mounting bracket and the pump. Reassemble the Drive 1. Insert the new machine key into the slot on the end of the pump shaft, and then slide the coupling onto the shaft. (Do not tighten the set screw). 2. Assemble the pump to the motor assembly. Ensure that the four spacers are replaced. 3. Adjust the coupling on the pump shaft so that there is a 0.8 mm (0.031 in.) gap between the couplings, and then tighten the coupling s set screw. 4. Lubricate the three new O-rings with Parker lubricant, and then insert them into their respective O-ring grooves on the pump. 2. Remove the coupling (D) from the end of the pump shaft and discard the machine key (E). 5. Remove any residual hot melt from the face of the manifold that mates with the pump. 6. Mount the manifold onto the pump. 3. Remove and discard the three pump O-rings. Continue

31 Disassemble the Pump 1. Remove the assembly screws (A). 2. Insert a flat-tip screwdriver into the notch (B) on each side of the pump plate, and then pry the pump plates (C) apart. 3. Remove and discard the internal retaining ring (D), the washer (E) and the pump seal. 4. Pull the shaft-gerotor assembly (G) out of the large pump plate. Remove the external gerotor (H) if it does not come out with the assembly. 5. Remove and discard the O-ring (I). G J H I C 6. Note which side of the internal gerotor (K) is facing the tapered end of the shaft. The internal gerotor must be installed onto the new shaft facing in the same direction. K L 7. Remove one of the crescent retaining rings (J) from the shaft, and then remove the internal gerotor (K) and the pin (L). Discard the retaining ring, pin, and shaft. A B 8. Clean the pump plates and gerotors using the appropriate cleaning fluid. E F A C D Nm ( ft.-lb) Continue

32 Rebuild the Pump 1. Rebuild the shaft-gerotor assembly using the new shaft, crescent retaining rings, and pin. Ensure that the internal gerotor is installed onto the new shaft facing in the same direction as it was on the old shaft. 2. Using the seal insertion tool, insert the new pump seal (F) with the spring side of the seal facing the pump plate. C 3. Insert the new washer (E), and then insert the new retaining ring (D). G J H I 4. Lubricate the new O-ring (I) (P/N ) with Parker lubricant, and then insert the O-ring into the O-ring groove on the pump plate. 5. Lubricate the gerotors (H and K) with high-temperature oil (Mobile Therm 603 or equivalent). A K L 6. Insert the shaft-gerotor assembly into the large pump plate. B 7. Reassemble the pump plates using the two assembly screws. Tighten the screws to Nm ( ft.-lb). D E Nm ( ft.-lb) F A C Complete the Installation 1. Reassemble the drive assembly. Refer to Reassemble the Drive on page Slide the drive assembly back into the chassis and reconnect the motor pigtail. 3. Complete the installation by reversing steps 2 through Restore power to the melter, and then switch the melter on. Verify that the melter operates normally.
