FREEWHEELS DIFFERENCE BETWEEN 390/420 AND 430/500 AE

[Michel Dufayard]

I have a 430 and a 420 automatic motor.
 When I have opened the 2 motors, I have compared
 the gears of the 2 motors. The two 430 freewheels are the same
 than two 420 freewheels . 420 motor has 3 freewheels ( one more than
 the 430).
 But when I look at parts lists, the parts number of the
 freewheels which are identical are differents.
 420 parts numbers are differents from 430 parts numbers.
 Can someone give an explication ?
 420 freewheels are easely avaliable, not 430 with 430 parts number.
 
Thanks
Michel

If they are the same size I would use them. My guess is......might just be a different supplier or different material in the freewheels so Husky gave them a different part number. May have different number of sprags etc. Either way it shouldn't matter.  Good luck.
