H42 speed up pulley
 

I picked up an H42 Haban thrower that needs a drive pulley not knowing the correct size for sure, was thinking I could use a smaller pulley to up the RPM's and throw the snow better. could someone tell me what size the org. pully is

what the heck, I know there are more out there. if I new the org Dia. of the drive pully I could base my new size off. Right now i have a 31/2 pully in mind

I don't have a H42 and only have knowledge of the original part number. BUT....IIRC seems that I read you could downsize to 3".

Keep in mind all of the H42 parts are NLA...I would not spin it faster and speed up the wear on everything. It should throw snow plenty far stock...do you have the chute coated with slip plate?

The thrower has to be kept full to throw snow the furthest. You will have to vary the groundspeed accordingly. When the thrower is full, the engine will be just tugging on the governor a bit.

the problem is it does not have a pully on it so i dont know what the stock size is?

IIRC, the OEM part was 3.5"

:bigthink:
There must be some H42 or H48 owners out there that could measure one up...:ThumbsUp:

That reference is for the IH QA Series snowthrowers NOT for the Habans

I saw that, thats whare I got the idea for the 31/2 pully but still dont know what the org size was to start with
