Compatible models: GROM (JC92), MSX GROM (MLHJC92), Monkey 125 Thai model (MLHJB03) Changed the crankshaft journal part from 2-point support to 3-point support. Crankshaft support adapter that increases the durability of the stock crankshaft.

Since the generator of the target vehicle is attached to the L. crankcase cover, the flywheel installation direction is closer to the outside (shaft tip). For this reason, the rotating 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 is doubled. This can cause interference between the generator and flywheel, adversely affecting ignition timing, or in the worst case, damaging the crankshaft. By installing a ball bearing in the stator, this product changes the crankshaft journal from 2-point support to 3-point support, limiting crankshaft runout that occurs in the high rotation range of bore-up engines. By restricting it, runout can be suppressed and the durability of the stock crankshaft can be increased. *You will need to check the stock crankshaft currently being used before purchasing. If the crankshaft is running out more than the standard value, it is necessary to correct the runout or replace the crankshaft. *A special tool rotor holder (00-01-1001) is required when removing the flywheel nut.
