2.1.3 Disassembly / Assembly of bearings and shims
The type of bearings (taper roller) ensures the absence of axial clearance on the bend shaft. The shims are
defined to meet this necessity. For disassembly / reassembly and for any replacements, carefully observe the
following directions:
A) Disassembly / Reassembly of the bend shaft without replacement of the bearings
After having removed the side covers as indicated in par. 2.1.1, check the conditions of the rollers and their
relative tracks. If all parts are in good condition, clean the components carefully with a degreaser and redis-
tribute lubricant oil uniformly.
The previous shims can be reused, taking care to insert them only under the indicator side cover.
Once the complete unit is mounted (Indicator side shaft + motor side flange), check that the rotation
torque of the shaft - with the con-rod disconnected - is a between 0.9 ft lbs. (4 Nm) and 1.35 ft lbs. (6 Nm).
To transition the two side covers closer to the crankcase, it is possible to use 3 M6x40 screws for the first
positioning phase, as already indicated above Fig. 8/a, and the screws provided for final fastening.
Shaft rotation torque (with the con-rod connected) should not exceed 1.8 ft lbs. (8 Nm).
