using feeler gauge. Height limit: 0.7mm
• Crankshaft: supporting the crankshaft at the two working points of oil seals, with
two comparators, measure the centering at the two working points of the bearings,
marked on diagram 2 with the letter A. Height limit: 0.05mm
• Measure the bearing seating, which must not be lower than the height limit:
24.98mm
• Check with a feeler gauge that the axle slack of the connecting-rod between the
two semi shaft, which must not exceed the height limit: 0.7mm
• Check the radial slack of the connecting rod on the coupling axle which must not
exceed the height limit: 0.05mm. This is detected by placing a comparator (B), as
shown in diagram 2, and moving the connecting rod vertically. The slack shown by
the comparator is assessed. Measure the diameter of the hole in the connecting-rod
foot. Height limit: 20.00mm
• Reed valve: Verify that between the frame and the reeds there is no space
(diagram 3). Height limit: 0.2mm.
WARNING: The reeds should not and cannot be turned (diagram 4)
