G30 kit Fan Hub, or the one from Zenoah?
Putting together a G30 and right after I put the engine assembly in the rear frames I discovered the among all the engine parts the Zenoah G29 3D max came with ANOTHER fan hub.

The one on the kit "seem" to fit perfectly.

Is the fan hub that came wit the engine any different?

I am at the stage fitting the clutch bell.

thanks

yes its different, the boring is slightly deeper

you can modify the bore in the hub in the kit and use it but if you don't either mod it or use the hub that came with the motor the hub will sit slightly higher and will cause an interference issue with the top of the clutch bell on the inside

I'd suggest just using the hub that came with the motor. At this stage of your build its still easy to switch

This ONLY applies to the HWC 3D Max motor as it uses a different crank

Thank you Mr Shurley, I much appreciate the guidance.

As you pointed out, it will be easy to swap the hubs at this stage.

This turned out very ironic.

I tried the fan hub that came with the engine and it was too high, pushing the clutch against the bell,

Went back to the one that cam with the kit and the clutch stack fit perfectly. Oh well
