Cylinder Head: Overhaul Honda Element I

Rocker Arm and Shaft Disassembly/Reassembly

Note. Identify each part as it is removed so that each item can be reinstalled in its original location. Inspect the rocker arm shaft and rocker arms (see ROCKER ARM AND SHAFT INSPECTION ). If reused, the rocker arms must be installed in the same positions. When removing or installing the rocker arm assembly, do not remove the camshaft holder bolts. The bolts will keep the holders and rocker arms on the shaft. Prior to reassembling, clean all the parts in solvent, dry them, and apply new engine oil to any contact points. Bundle the intake rocker arms with rubber bands to keep them together as a set. When replacing the intake rocker arm assembly, remove the fastening hardware from the new intake rocker arm assembly.

1. Remove the rocker arm assembly (see «ROCKER ARM ASSEMBLY REMOVAL»(ref-220562-S04028856712006022000000) ), then disassemble the rocker arm assembly (see «ROCKER ARM AND SHAFT DISASSEMBLY/REASSEMBLY»(ref-220562-S18086204362006022000000) ).
2. Measure the diameter of the shaft at the first rocker location.
3. Zero the gauge (A) to the shaft diameter.
4. Measure the inside diameter of the rocker arm, and check it for an out-of-round condition. Rocker Arm-to-Shaft Clearance Standard (New): Intake: 0.025-0.052 mm (0.0010-0.0020 in.) Exhaust: 0.018-0.056 mm (0.0007-0.0022 in.) Service Limit: 0.08 mm (0.003 in.)
5. Repeat for all rocker arms and both shafts. If the clearance is over the limit, replace the rocker shaft and all overtolerance rocker arms. If any VTEC rocker arm needs replacement, replace the rocker arms (primary and secondary), as a set.
6. Inspect the rocker arm pistons (A). Push each piston manually. If it does not move smoothly, replace the rocker arms as a set. NOTE: Apply new engine oil to the pistons when reassembling.
7. Install the rocker arm assembly (see «ROCKER ARM ASSEMBLY INSTALLATION»(ref-220562-S02568173792006022000000) ).
