Crankshaft Support Adapter CRF110F

[SP Takegawa 01-10-0151 Crankshaft Support Adapter for CRF110F Engine Parts]
■Product Description
A crankshaft support adapter that changes the crankshaft journal from two-point to three-point support, suppressing crankshaft runout at high RPMs and enhancing the durability of the stock crankshaft.

■Detailed Description
Since the generator for the target vehicle is installed on the L. crankcase cover, the flywheel mounting direction is closer to the outside (crankshaft end).
For this reason, the rotational weight of the heavy flywheel is applied to the outside of the crankshaft tip, and in engines with improved pickup, the load during acceleration and deceleration doubles.
As a result, the generator and flywheel may interfere, negatively affecting ignition timing, or in the worst case, the crankshaft may be damaged.
This product incorporates a ball bearing within the stator, changing the crankshaft journal from two-point to three-point support, thereby limiting crankshaft runout that occurs at high engine RPMs.
By limiting this, runout is suppressed, and the durability of the stock crankshaft can be increased.
It eliminates the need for crankshaft replacement and provides an assembly structure that allows for three-point support of the crankshaft journal when installed on genuine parts.
