PARTS REPLACEMENT SCHEDULE
1. Replace compression rings every 3 years (2 years if 60 or more hours/week run time).
2. Replace control rings every 3 years (2 years if 60 or more hours/week run time).
3. Change both main shaft and con rod bearings every 4 years (3 years if 60 or more hours/week run
time).
4. Replace head valves or valve plates every 2 years (1 year if 60 or more hours/week run time).
PISTON RING REPLACEMENT
Piston rings can be inspected or replaced by doing the following:
1. Make sure all power is off to the unit and the air receiver is at 0 PSIG.
2. Loosen and remove the discharge line or manifold.
3. Loosen and remove the four capscrews holding the cylinder to the crankcase.
4. Pull the cylinder/head assembly straight off of the crankcase (Take care not to damage the
piston/con rod during this removal).
5. The piston and rings will then be exposed.
6. Inspect and replace the rings as required (Note that the CCE30 and CVE50 compression rings are
of the two separate piece design and take care not to drop or break the overlap ends of the ring).
7. Replace rings on piston and carefully slide cylinder over the piston until it sets on the crankcase.
8. Tighten four capscrews that hold the cylinder to the crankcase.
9. Reinstall the discharge line or manifold.
CCE10 CRANKSHAFT BEARING AND CON ROD REPLACEMENT
Crankshaft bearings can be replaced as follows:
1. Disconnect all power to the unit and bleed down the air receiver pressure to 0 PSIG.
2. Remove the belt guard and the V-belt.
3. Remove the flywheel.
4. Remove the cylinder from the crankcase.
5. Loosen the two setscrews in the pin boss area tightened against the pin on the inside area of the
piston.
6. Push the piston pin out to remove the piston from the top of the con rod.
7. Remove crankcase breather cover and foam material on the front end of the crankcase. This will
expose a round opening in the crankcase in line with the crankshaft end.
8. Remove snap ring on the rod of the crankshaft using snap ring pliers.
9. Remove the con rod assembly using a gear puller.
10. If only installing con rod assembly, heat the lower end bearing on a hot plate to 190°F. Using heat
resistant gloves, quickly slide bearing on the rod of the crankshaft to proper location and reinstall the
snap ring.
11. Remove the 2 capscrews located inside the crankcase on the flywheel end.
12. Remove the flywheel key located on the crankshaft outside the crankcase.
13. Carefully remove the crankshaft from the crankcase using a press.
14. Remove the first bearing (smaller) from the crankshaft using gear puller.
15. Remove snap ring on the crankshaft using snap ring pliers.
16. Remove the second bearing (larger) from the crankshaft using gear puller.
17. To install new crankshaft bearings on the shaft, heat bearings to 190°F. Using heat resistant gloves
quickly slide larger bearing to proper location on the crankshaft, reinstall snap ring, then slide smaller
bearing to proper location on the crankshaft.
18. Reassemble compressor by reversing procedures stated 1 through 13.
