7 mm
E504
Blower wheel + Adapter
For Kokusan ignition
Fits MS50 and VZ50 and more.
To be used in connection with the installation of Ignition system E500
Requires 4 mounting holes in flywheel, which are only found on E500 and not other kokusan types.
Fan wheel is originally used and professionally turned down to fit, without this having any practical effect on the operation of the engine.
Do not expect used parts to be cleaned.
The one adapter and fan wheel must be heated to 100 degrees (e.g. in an oven).
This is because this must sit perfectly tight on the flywheel.
Use work gloves without holes when assembling.
Also included are 4 screws for mounting the adapter.
Note that the "trace" on the back of the flywheel is 7 mm wide.
There are two different fans - the other (E503) which is 4mm wide.
