I am in the process of some fairly extensive modifications to my MAX 4

I have the kawasaki FD750 liquid cooled engine .

I have relocated radiator from the top of engine to be inline with the crankshaft
With the cooling fan directly connected to a stub shaft mounted to the flywheel

The stubshaft is a 2nd hand unit from a john Deere 550, or Toro,made for the kawasaki
Air cooled versions to run a cooling fan

I punctured my radiator backing into a tree branch a year ago, so having the radiator
Mounted lower will protect it.
The other plus is if the air cleaner is shifted lower, you now have a decent size
Cargo storage compartment about 6 inches deep.

But the primary purpose for release acting radiator is to provide space for a belt driven alternator, a small AMR300 supercharger and a PTO drive.

To be continued.......
