Remove the guide springs from the lifters.Install Valve Lifters
Steps 1 and 2 must be done to install intake or exhaust valve lifters.
Make sure guide spring (1) is not damaged or worn. If the guide spring is damaged or worn, replace the guide spring. See Guideline For Reusable Parts.
1. Install guide spring (1) on the valve lifters. 2. Put the intake or exhaust valve lifter in position in 5P2395 Holder (5) of tooling (A). Install 5P2685 Nut (4) and 5P2400 Compressor (3) on 5P2408 Outer Handle assembly (2). Install the 5P2400 Compressor on the lifter over the guide spring. Immerse the lifter assembly in engine oil before installing it in the cylinder block lifter bore. The opening in the cylinder head assembly for the intake valve lifter is larger than the opening in the exhaust valve lifter side. All tooling and valve lifters must be installed and removed from the intake valve lifter side. 3. Install the exhaust valve lifters with tooling (A) as follows: Be sure to install the original valve lifters in their respective bores. New valve lifters can be mixed.a. Install exhaust valve lifter (6) and the handle assembly in the cylinder head opening on the intake valve lifter side. Slide the flat area of the 5P2408 Outer Handle Assembly through the casting in the cylinder head assembly. b. Put the exhaust valve lifter in the valve lifter bore of the cylinder block. Install tooling (A), the 5P6599 Inner Handle Assembly in the 5P2408 Outer Handle Assembly and push the exhaust valve lifter with tooling (A).c. Remove tooling (A), the 5P6599 Inner Handle Assembly from the 5P2408 Outer Handle Assembly. Slide the 5P2408 Outer Handle Assembly to the intake valve lifter side of the cylinder head and remove it.4. Install the intake valve lifters with tooling (A) as follows: Be sure to install original valve lifters in their respective bores. New valve lifters can be mixed.a. Install tooling (A). The 5P6599 Inner Handle Assembly in the 5P2408 Outer Handle Assembly.b. Install the intake valve lifter into the valve lifter bore of the cylinder block with tooling (A).
