5.9 Servicing the Four-Way ValveUnlike older units, new Corken compressors mounted inthe –107 arrangement are being supplied with a non-lubefour-way valve. No maintenance is normally required onthis valve. If you have reason to disassemble the valve,please follow the instructions below (see figures 5.9Aand 5.9B).CAUTION: Always Relieve Pressure In The UnitBefore Attempting Any Repairs.Before Disassembly:1. Record the position marks on the end of the rotor shaft.2. Record the positions of the handle stops on the cap.NOTE: A small amount of silicone grease appliedto each part before assembly facilitates assemblyif allowed.DisassemblyRefer to the drawing for item description.Figure 5.8A1. Remove the hex nut, indicator plate and handle fromthe rotor shaft.2. Remove the four hex head bolts and the cap from thebody. The cap should be rotated until free; do not pry.Inspect cap for wear and damage (see figure 5.9C).Figure 5.9A Figure 5.9B24
7. Place the cap over the rotor shaft.8. Rotate the rotor so the position of the handle stops onthe cap is the same as recorded before disassembly.9. Assemble the four hex head bolts through the capand into the body. Be sure that the body O-ring is inthe proper position and tighten the hex head bolts.Figure 5.9C3. Remove the body O-ring, stem O-ring, cap O-ring,and top rotor washer and discard.4. Remove the rotor and four seals as a unit from thebody. IMPORTANT: Because of the close tolerance,care must be taken to remove the rotor on its axis toprevent damage to the rotor and body. Rotating thehandle with a lifting action will help remove the rotoras shown in figure 5.9D.10. Reassemble the handle, indicator plate and hex nut.Be sure that the handle is assembled so that the stopon the handle mates with the stops on the cap.Chapter 6Extended Storage ProceduresFollowing a few simple procedures will greatly minimize therisk of the unit becoming corroded and damaged. Corkenrecommends the following precautions to protect thecompressor during storage:1. Drain the crankcase oil and refill with rust inhibiting oil.2. Operate for a few minutes while fogging oil into thecompressor suction.3. Relieve V-belt tension.Figure 5.9D5. Discard the four seals. Inspect the rotor for wearand damage.6. Remove the bottom rotor washer and discard.Inspect the body for wear and damage.AssemblyRefer to figure 5.9B. Have the repair kit laid out.4. Plug all openings to prevent entry of insects andmoisture. (The cylinders may also be protected by theuse of a vapor phase inhibitor, silica gel, or dry nitrogengas. If the silica gel is used, hang a tag on the unitindicating that it must be removed before start-up.)5. Store in a dry area, off the ground if possible.6. Rotate the flywheel every two weeks if possible.1. Place the new bottom rotor washer into the body.2. Assemble the four seals and O-rings onto theappropriate surfaces of the rotor.3. Assemble the rotor and seal assembly intothe body. IMPORTANT: Because of the closetolerance, care must be taken to press the rotoron its axis to prevent damage to the rotor andbody. A ring compressor is helpful. Be sure thatthe rotor is bottomed in the body.4. Rotate the rotor so that the position marks on theend of the rotor shaft are the same as recordedbefore disassembly.5. Assemble the new top rotor washer and cap O-ring,onto the shoulder of the rotor.6. Assemble the new stem O-ring and the body O-ringinto their grooves in the rotor and body.25
