Figure 148 47507 Still with the camshaft (4) set on the tailstocks (1), check the alignment of the supporting pins (3) with the dial gauge (2); it must be no greater than 0.030 mm. If you find a greater misalignment, replace the shaft. Figure 149 1 47505 To check the assembly clearance, measure the inside diameter of the bushings and the diameter of the pins (1) of the camshaft:
the difference will give the actual clearance. If you find any clearances over 0.135 mm, replace the bushings and, if necessary, the camshaft as well. Base q November 2006 Print 603.93.641
