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.
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.
