Important: Some engines will have both standard and 0.010 inch oversize valve lifters. The oversize valve lifter will have a 10 etched on the side. The block will be stamped O.S. on the cast pad adjacent to the valve lifter bore and on the top rail of the cylinder case above the valve lifter bore.
Notice: Prime the new valve lifters before installation. The valve lifters may be damaged if the valve lifters are dry when the engine is started.
Important: The valve lifters must be installed in their original locations.
Important: The straight edge of the guide plates and clamps face away from the cylinder.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Important: After all the clamps are installed, turn the crankshaft by hand two full revolutions, to ensure free movement of the valve lifters in the plate. If the engine will not turn over by hand, one or more of the valve lifters may be binding in the plate.
Tighten
Tighten the clamp bolt to 27 N·m (20 lb ft).
