That is a simple job for those with the know how.
Fortunately for you I have the know how and experience.
I have heard Aussie muttering about the damn blade setup and soldering
requireing jigs etc but being a Kiwi I think outside the square
And no jig required.
I have also witnessed mutterings bout bending the compound angles for tower.
Once agin a simple job
Cost could be the issue .
Complete new fan/blade setup ready to paint and run NZ$75.00
Tower and large pulley , axles , piston/cylinder ,engine bracket ?
Cheers
