ACTION REQUIRED
Show/hide table
There are two different repair actions in this program depending if there is a remanufactured cylinder head available for the engine. The Affected Product and associated Parts Needed have been divided into groups specific to the repair. No Remanufactured Cylinder Head Available: If a broken outer valve spring is found, all of the valve springs packs on the engine should be replaced. This action can be done without removing the cylinder heads from the engine by bringing the piston to top dead center and removing the rotator and keepers. Pressurizing the cylinder may be required. New inner and outer springs, rotators, exhaust valve spring washers, inlet valve stems seals and keepers should be used when reassembling. Remanufactured Cylinder Head available: For engine with a remanufactured cylinder head available, replace the existing cylinder head on each cylinder with a remanufactured cylinder head. This work should be completed only after inspecting the top end and determining no other engine damage has occurred. Refer to appropriate Service Manual as required. NOTE: If the valve has made piston contact the cylinder pack and cylinder head should be replaced. |
