Remove only those OEM engine components necessary to access the front of the VMAC compressor. It is NOT necessary to remove the compressor from the engine to perform this update. 2. Disconnect the existing air intake tube from the intake spigot. Keep components for re-installation later. 3. Put rag underneath Inlet Valve before disassembling to prevent oil dripping on other components (figure 1). 4. Remove inlet cover from compressor (3 M6 bolts – 5 mm Allen head). Keep bolts for re-use (figure1). Figure 1 Figure 2 5. Remove snap ring securing existing inlet valve. Keep snap ring for re-use (figure 2). 6. Remove existing inlet valve and discard valve. 7. Position supplied O-ring in inlet cover (figure 2). 8. Install supplied spigot in inlet cover (figure 2). 9. Secure spigot in inlet cover using snap ring removed in step 4 (figure 2). Tap on the snap ring with a hammer and non-marring punch to ensure the snap ring is fully seated in its groove. The snap ring must be fully seated to prevent intake valve assembly failure. 10. Insert poppet/O-ring assembly into spigot and push till it seats (it will produce an audible click). This keeps the poppet valve in place for assembly (figure 3).

Insert retrofit adapter into compressor front cover. Refer to Figure 3. 12. Ensure existing front cover O-ring is fully seated in O-ring groove. It may help to use compressor oil to “stick” Oring in groove. 13. Apply BLUE Loctite® on the bolts removed during step 3. 14. Position supplied spring between boss on retrofit adapter and boss on back side of poppet. Refer to Figure 3. 15. Re-using the bolts removed during step 3, install intake cover assembly on compressor leaving bolts finger tight. Do not torque bolts yet. 16. Push end of brass poppet, and ensure poppet cycles smoothly back and forth. It will take some force to initially open the valve. This is normal operation. 17. Torque inlet cover bolts to 5 ft.lbs or 54 in.lbs, then push on end of poppet to ensure smooth motion. 18. Re-install intake hose. 19. Re-install OEM components.
