The generator of the vehicle is attached to the L.crankcase cover, so the flywheel mounting direction is towards the outside (shaft tip).
Therefore, the turning weight of the heavy flywheel is placed outside the crankshaft tip, which increases the burden of acceleration and deceleration in improved pickup engines.
This can cause the generator and flywheel to interfere with the ignition timing, or even damage the crankshaft.
This product uses ball bearings inside the stator to change the crankshaft journal from 2 points supports to 3 points and limits the crankshaft sway caused by the high rotation range of bore up engines.
By limiting the ability to reduce shaking and increase the durability of the normal crankshaft.
Before purchasing, you will need to check the normal crankshaft that is currently used.
If the crankshaft is more than the standard value, you need to shake it or replace the crankshaft.
Special tool rotor holder (00-01-1001) is required when removing flywheel nuts.
