Removal and Installation
REMOVAL
1. Cylinder Head must be removed to gain access to tappets for service.
2. Remove yoke retainer and aligning yokes.
3. Use Tool C-4129, or equivalent to remove tappets from their bores. If all tappets are to be removed, identify tappets to insure installation in
original location.
NOTE: If the tappet or bore in cylinder block is scored, scuffed, or shows signs of sticking, ream the bore to next oversize and replace with
oversize tappet.
CAUTION: The plunger and tappet bodies are not interchangeable. The plunger and valve must always be fitted to the original body. It is
advisable to work on one tappet at a time to avoid mixing of parts. Mixed parts are not compatible. Do not disassemble a tappet on a dirty work
bench.
INSTALLATION
1. Lubricate tappets.
2. Install tappets in their original positions.
3. With roller tappets, install aligning yokes.
4. Install yoke retainer and torque screws to 12 Nm (105 inch lbs.).
5. Install cylinder heads.

CAUTION: To prevent damage to valve mechanism, engine must not be run above fast idle until all hydraulic tappets have filled with oil and
have become quiet.
