Inspection
• Inspection of the exhaust manifold. Inspect the
plane surface of the plane on which the
manifold and the cylinder head are to be
installed.

Manifold installation plane surface mm (in)
Standard 0.3 (0.01) or lower
Limit 0.5 (0.02)
Note:
If the plane surface exceeds the limit, replace it.

• Check a crack in the exhaust manifold visually.
Carefully inspect the turbocharger for abrasion and/o
r
excessive wear. Make any necessary adjustments,
repairs, and/or part replacements.

Wheel shaft axial play
Use a dial gauge to measure the wheel axle shaft pla
y
when a force of 12 N (1.2 kg / 2.6 lb) is alternately
applied to both sides of the compressor wheel.

Axial play mm (in)
