PUMP DISASSEMBLY: 1. Place the pump on a flat workbench. Remove both cover plates and set them aside. 2. Using a 7/16-inch wrench, loosen the bolts that run through the pump and remove the six nuts. Pull the bolts through the pump body and set them aside. 3. The fluid caps and manifolds may fall free at this time. If not, grasp the fluid caps and separate them from the pump body. 4. The air inlet fluid cap has two small ``O"rings at the air inlet and exĆ haust ports. Remove these with the ``O"ring pick. 5. The manifold tubes may have pulled free of the pump when the fluid caps were removed, if not remove both tubes from the pump body. 6. Remove the ``O"rings from the ends of each manifold tube. 7. If the manifolds did not fall free, separate them from the fluid caps at this time. 8. To remove the checks, it may be necessary to push a dowel through the fluid caps. 9. Use the pick to remove any ``O"rings that remain in the manifold or fluid cap. 10. With the 9/16" socket and 9/16" wrench, loosen and remove either diaphragm nut. Gently pull the diaphragm away from the pump body. NOTE: Models with PTFE diaphragms will have back up ``O"rings. 11. Push the connecting rod through the pump body. Wrap the conĆ necting rod in a shop rag and secure in a soft-jawed vise. 12. Remove the remaining diaphragm nut with a 9/16-inch wrench. NOTE: Be careful not to mar the connecting rod surface during this step. 13. Using the 9/16" wrench and the spanner wrench, remove the backĆ up washer from the diaphragm nut. This will allow you to separate PAGE 6 OF 8 14. 15. 16. 17. 18. the diaphragm from the nut. NOTE: Be careful not to round the diaphragm nut during this step. Pull apart the two air caps. The connecting rod bushing will fall free. If the air valve block asm. did not fall free, pull it from the air cap at this time. Use the ``O"ring pick to remove the air cap seal. Use the pick to remove the U-cups and any ``O"rings that may reĆ main in the air caps. Remove the retaining screws and separate the valve block and miĆ nor valve block. Pull the piston from the minor valve block. Then remove all ``O"rings using the pick. Gently push the spool from the valve block. A dowel may be needed to push out the spool. NOTE: Be careful not to damage either part during this step. Use the pick to remove all ``O"rings from the spool and the center gasket from the valve block. PUMP REBUILD PROCEDURES: (rebuild by service kits) For the 637273-XXX and 637275-XX Service Kits AIR VALVE SECTION (Steps 1-6) 1. Install new ``O"rings and U-cup on the spool and piston. 2. Lubricate the spool, piston and internal bores of the valve blocks. 3. Insert the piston into the minor valve block, being careful not to damage any ``O"rings during this process. Now slide the spool into the valve block, inserting the small end first. NOTE: There may be some resistance when installing the piston and spool, however you should not have to force the parts into place. 4. Install the shaped gasket into the minor valve block and push the major valve block into the minor valve block, retain with screws and torque to 6 in.lbs. NOTE: Do not lubricate the gasket or valve block surfaces. 5. Insert new, lubricated ``U''cups in each of the air caps. The lips of the ``U''cups should face towards the diaphragm chambers. Install the air cap seal. 6. Pre-assemble each of the two diaphragms by first inserting the diĆ aphragm nut through the new diaphragms, Appy Loctite #242 to the threads, attach the backup washer, secure with the a 9/16" wrench and spanner wrench. Using a torque wrench, tighten the diaphragm nut and washer to 80-inch pounds. NOTE: Be careful not to round off the diaphragm nut. Backup ``O"rings are included in the Service Kit for models with PTFE diaĆ phragms. For the 637274-X and 637273-XXX Service Kits: 7. Install new, lubricated ``O"rings onto the four complete check asĆ semblies that are included with the Service Kit. Also put new ``O"rings on each end of the two manifold tubes. PUMP REASSEMBLY: 8. First hand tighten the connecting rod to one of the diaphragm asĆ semblies. 9. Place the air cap on end. Insert the air valve assembly and bushing in place. (be sure the U-cups are installed). Align logo plates and push the air caps together. NOTE: Be sure the bushing, and air valve assembly remain in place. 10. Lubricate the connecting rod and insert it into the air cap. NOTE: Models with PTFE diaphragms have backup ``O''rings that are placed in the groove of each air cap. 66602X-X REASSEMBLY (CONT’D) 11. Attach the second diaphragm assembly to the connecting rod, hand tighten the (pre-assembled) diaphragm nut and washer until it bottoms out on the connecting rod. NOTE: Models with Teflon diaphragms have backup ``O"rings that are placed in the groove of each air cap. Do not over-tighten the nut. 12. Replace the ``O"rings at the air inlet and exhaust ports of the air inĆ let fluid cap. 13. Properly align the fluid cap and attach it to the pump body. When in place, the air inlet should be at the upper right, with the exhaust at the lower left. 14. Insert a bolt into the bore just below the air inlet and one just above the exhaust port. Applying a small amount of anti-seize compound or lubricant to the threads will help prevent the nut from binding. Properly align the second fluid cap and push it into position. 15. Secure the fluid caps by installing nuts onto each bolts, but do not tighten fully at this time. 16. Insert the manifold tubes through the pump body, being careful that the ``O"rings do not fall off during this step. 17. Press two of the check assemblies into the lower inlet ports of the fluid caps. The checks are keyed and can be assembled only one way. NOTE: If the old checks are to be used, clean all parts in an apĆ propriate solvent. 18. Place manifolds over each check, pushing firmly to secure the check and the manifold tube. 19. Press the remaining checks into the upper, outlet ports of the fluid caps. Make sure the smaller seat opening is inserted first. 20. Place manifolds over each check, pushing firmly to secure the check and the manifold tube. 21. Insert two bolts through each manifold. Secure by attaching a nut to each bolt. Applying a small amount of anti-seize compound or lubricant to the threads will help prevent the nut from binding. 22. Tightening sequence for the long bolts: IMPORTANT ASSEMBLY NOTE: The fastener nuts have ribs which lock into the material, for best results place a socket wrench on the nuts so they are held stationary and tighten only the bolts they are used with. . Torque all six bolts to 40-inch pounds. . Cross tighten the bolts in an alternating star shaped pattern. . Repeat torque sequence twice. 23.
