Camshaft, Measuring Radial Clearance: Procedure

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Audi S8, 2015 Audi A8 Quattro, 2014 Audi S8, 2014 Audi A8 Quattro, and 2013 Audi S8. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Use old bolts to measure radial play.

-- 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.

-- Clean the bearing and the bearing journals.

-- Place Plastigage® over entire width of bearing journal or into bearing.

Plastigage® must rest in center of bearing.

-- Install the camshafts, mount the camshaft housing and tighten using the old bolts, refer to Figure. When doing this, be careful not to rotate the camshafts.

-- 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.)

-- Replace bolts for the final assembly.
