Pic. 2.157. Measuring the inner diameter of the tappet bore
Measure the inner diameter of the tappet bore in the X and Y directions at two points (A and B) (pic. 2.157).
- Inner diameter: 31.00–31.03 mm.
Pic. 2.158. Measuring the outer diameter of the tappet bore
Measure the outer diameter of the valve lifter body in the X and Y directions at two points (A and B) (pic. 2.158).
- Outer diameter: 30.97-30.98 mm.
Subtract the outside diameter of the valve lifter housing from the inside diameter of the valve lifter bore. If the clearance is not correct, replace the valve lifter or cylinder head.
- Standard clearance: 0.02–0.06 mm.
- Maximum: 0.15 mm.
