Takegawa - Crankshaft Support Adapter

Since the GROM / MSX125 / MSX125SF generator is mounted on the L. crankcase cover, the flywheel mounting direction is closer to the outside (shaft tip). For this reason, the rotational weight of the heavy flywheel is applied to the outside of the tip of the crankshaft, and in an engine with improved pickup, the burden during acceleration and deceleration doubles. This can cause the generator and flywheel to interfere, adversely affecting ignition timing and, in the worst case, damaging the crankshaft.

This product changes the crankshaft journal part from 3-point support to 4-point support by installing a ball bearing in the stator, and limits the runout of the crankshaft that occurs in the high rpm range of the bore-up engine. By limiting it, runout can be suppressed and the durability of the normal crankshaft can be improved.

Assembling structure that can support the crankshaft journal part at 4 points by attaching it to genuine parts without the need to replace the crankshaft.

Before purchasing, it is necessary to check the normal crankshaft currently in use.
If the crankshaft is shaken above the standard value, it is necessary to remove the runout or replace the crankshaft. The product number of the crankshaft support adapter differs because the mounting shape to the stator comp differs depending on the vehicle name and frame number.
