Reference: Information Release Memo (IRM), 90-11, Form PELE0168, "New Exhaust Valves Used In Remanufactured Cylinder Heads".

There has been some customer concern regarding the use of Remanufactured exhaust valves with Remanufactured cylinder heads in certain applications. The decision to use NEW exhaust valves in Remanufactured cylinder heads will enable the customer to choose Remanufactured cylinder head groups with greater confidence. This will provide the customer with the maximum exhaust valve life expected from a quality Remanufactured product.

Since September 1, 1990, all Caterpillar Remanufactured cylinder heads have been assembled with NEW exhaust valves. The cylinder head part numbers will NOT change. Date codes of 9/90 and later will identify those heads with the new exhaust valves. The date code is stamped near the remanufactured part number on the cylinder head.
