Check status of crankcase bearing, replace after 30 hours suggested or 60 hrs max.
Place crankcase halves under press (use tool as per drawing S 725 / 1).
Or better heat crankcase half at 70°C. If necessary insert the bearing shims.
Insert the bearing, the balls have to be on upper side and visible during the assembly (for both
halves).
Then, insert the crankshaft as was positioned in the original installation and close temporarily the
crankcase for axial clearance check.
Fixing the crankcase with only 3 / 4 screws with 5mm ALLEN WRENCH – T-TYPE
In this step, tighten the screws to approximately 8 Nm (70 lb-in). Check the Axial Clearance.
Check the Axial Clearance
For the check use a check tool for crankshaft axial clearance as in picture. The clearance must be
between 0.25÷0.35mm. If lower or higher disassemble the crankcase, extract the bearing and use
different steel shims (0.10/0.15/0.20) to recover clearance. Shims must be equally positioned.
