Inspection

INFOID:0000000010282010

INSPECTION AFTER REMOVAL

Camshaft Journal oil clearance

CAMSHAFT JOURNAL
• Measure the camshaft journal with a micrometer (A).

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 

MA-59, "Fluids and Lubricants"

.

• Use procedure below to check for fuel leakage.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• 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

specified level, if necessary.
