Used Timberwolf tw150 fan.

Some of the early ones also had much thinner fan blades.

Best bet would be to get hold of a flywheel from another make, then put the rest of the 'other make' chipper around it - that's the only way to solve this much publicised issue - cos until TW re-design the central component it aint gonna go away.

 

OK TW huggers - fire away!

Do they help throw chip further if changed for new?

 

Yes they do if the old ones are really battered, i changed mine recently and the performance is much better. Conifer now ends up in the truck instead of on the road. Mine had lumps missing from them. I'd definitely fit new ones though.

Balance by snapping off opposite fins to broken ones, remove exit chute and reach in with long punch and hammer, I did this a few years ago for a temporary fix to finish a contract!!

 

No you can't change without removing flywheel!

Im sure that Doug Bennet made some balanced sets in steel years ago.
