INSPECTING THE CRANKSHAFT ALIGNMENT
To install the drive shaft on the support and to measure the
misalignment in the 4 points indicate to you in figure.
- Check that the driving shaft cone, the tab seat, the oil guard
connection and the threaded tangs are in good working or-
der.
- In case of failures, replace the driving shaft. The connecting
rod head brasses cannot be replaced.
For the same reason, when cleaning the driving shaft, be
careful to prevent any impurity from entering into the shaft
lubrication hole.
In order to prevent damaging the connecting rod brasses, do
not attempt cleaning the lubrication duct with compressed
air.
- Make sure that the 2 pads on the crank button are properly
mounted.
- A wrong installation of a pad can seriously affect the brass
lubrication pressure.
