-- Remove the camshafts, refer to REMOVING .

-- Mark the assignment of the roller rocker lever for installation later.

-- Remove the roller rocker lever and place it on a clean surface.

-- Remove the camshaft housing and the camshafts again.

-- Compare width of Plastigage® with calibrated scale.

Radial clearance:

• With bearing-diameter 24 mm (0.944 in.): 0.024 to 0.066 mm (0.0094 to 0.0025 in.)
• For 36 mm (1.417 in.) diameter bearings: 0.032 to 0.078 mm (0.0012 to 0.0030 in.)
