Installation tip:The transition between the crank webs and the crankpin is provided with a slight radius for reinforcement. To ensure clean spacing, a Ø 16 x 1 mm spacer washer should be used on both the left and right-hand sides; these are placed neatly over the chamfer and are therefore perfectly centered. The other spacers can be used normally with Ø 15 mm.
&Revised version of the previously offered crankshaft with additional slotted connecting rod foot for better lubrication, improved balancing ratio and thus better speed stability.
