CYLINDER HEAD HOUSING AND CAMSHAFT BRACKET INNER DIAMETER
• Measure the inner diameter (A) of cylinder head housing and cam-
shaft bracket with a bore gauge.
CAMSHAFT JOURNAL OIL CLEARANCE
• (Oil clearance) = (Bracket inner diameter) – (Camshaft journal diameter)
• If it exceeds the standard, replace camshaft or/and cylinder head housing and cylinder head assembly.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to

• Warm up engine thoroughly to check there is no leakage of fuel, exhaust gases, or any oil/fluids including
engine oil and engine coolant.
• Bleed air from lines and hoses of applicable lines, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
