1. Fit support base of graduated disc 1860896000 onto auxiliary component drive pulley and secure to pulley using a screw. Then fit graduated disc onto its support base so that "0" on disc is aligned with the fixed pointer positioned previously.
2. Turn the crankshaft through about 10° in its normal direction of rotation by applying a wrench to the auxiliary component drive pulley retaining nut. Measure piston axial displacement off gauge (e.g. 0.6 mm).
3. Turn the crankshaft against its direction of normal rotation by about 20° in relation to the fixed pointer. Turn crankshaft back through its normal direction of rotation until gauge shows the same axial displacement measured previously (e.g. 0.6 mm).
4. Read angular value corresponding to previous axial displacement (e.g. 8°) off the graduated disc. Take the arithmetic mean of the crankshaft angle set at the beginning of the procedure (10°) and the current value (8°). Then release the graduated disc from its base, locate at setting obtained by taking the arithmetic mean (e.g. 9° = mean of 10° and 8°) in relation to the fixed pointer without turning the crankshaft. Then tighten graduated disc again.
