HLA

HLA





1. Measure the HLA hole inner diameter in X and Y directions at the two points (A and B) shown.

Diameter: 30.000-30.025 mm (1.1811-1.1820 in)





2. Measure the HLA body outer diameters in X and Y directions at the two points (A and B) shown.

Outer diameter:
29.959-29.975 mm (1.1795-1.1801 in)

3. Subtract the HLA body outer diameter from the HLA hole inner diameter.

Clearance
Standard: 0.025-0.066 mm (0.0010-0.025 in)
Maximum: 0.180 mm (0.0071 in)

4. If the clearance exceeds the maximum, replace the HLA or cylinder head.
