Greenmech Eco 150 flywheel issue HELP!!!!

[76AR]

I have recently purchased a greenmech eco 150. Upon close inspection the bearings were completely shot and have worn considerable ring into the shaft!

 

Can you remove the shaft like you can on timber wolfs and simply replace them?

 

If not I have another eco150 that's 3 years older which has a complelty goosed engine. I was thinking of taking the fly wheel from that machine and swapping it but are they the same size I can't tell without stripping it fully down???

 

Thirdly I could get the shaft built up and re machined but is this a wise option or will it be highly likley to fail???

 

Any help would be greatly appreciated.

 

Cheers
