QA 36/42 snowthrower aftermarket drive pulley?
 

Hi guys, New to this forum, been lurking around for a long time though. I have a QA snowthrower for my Cub Cadet 129. It's complete, however; it is missing the drive pulley for the gear box. I can pick up a new pulley no problem but I need some more information that I cant seem to find?

What is the correct belt to drive this?

Can I use a zinc stamped pulley like from farm supply store? or should I use a Cast Iron Sheave with Taper-Loc insert on the shaft?

Worried about one of the stamped pulleys coming apart due to the RPM, look kind of cheap.

Cast iron taper lock is the way to go.
Try surplus center for a good price.
Don't like those stamped sheet metal sheaves either.

Nice to see someone fixing the winter equipment long before it will be needed rather than "It's snowing and my stuff is broken" well done! :beerchug:

Thanks guys! my local surplus store has both. any idea on what the correct belt size is?

I think mine runs a Napa 4L300, but I'll double check that for you when I get out to the shed today.

Ya might wanna get the pulley first and installed then run a tape measure around the pulleys to be sure,
33" is a close length on most, but vary depending on pulley size and model involved.
-----and close only counts on horse shoes and hand grenades.:Poof:
Some enterprising fellers go to tsc or hwd store and get several lengths then return the incorrect ones.
Do remember to take in account there is quit a bit of belt adjustment on them.

Just checked, mine's a 4L300W, but bear in mind I'm running it on a 125 narrow frame. Geometry SHOULD be the same, but trying a few and returning the non-fits is a good practice. I'm running a qa-42a, and it came off a 129.
