QA42A pulley
 

I just scored a nice, tight QA42A on the cheap and i want to put it on the 782 or the 1211. I already know i need different upper bars and a pulley but i don't know what diameter pulley i need? I tried looking it up but i must be stupid and can't find anything.

Does it have a pulley on it now? If so, what size is the PTO on those engines?

I can check the pulley diameter on my 125 and QA42 tomorrow

Item 4 in the diagram below is what you seek. Part number is IH-78055-C2 and is still available. I don't see a diameter listed anywhere, but with the part number maybe you can do some cross referencing.

Pulley is the same size, but the width is different.

Tim-Outside diameter on the pulley is 4 1/2".

Thank you all for the information, now I can begin the search.

Cast iron browning BK50 ---4.75 on outside diameter.
www.Surplus center lists it for about $14.00,
if you want to speed it up, go 1 tooth bigger on the drive sprocket :beerchug:

I'm far from a pulley expert but i found this and i think it would work. It's a 1/4" smaller so it should speed the thrower up just a bit, Opinions?

Think that will work,and speed it up a tad.:beerchug:

It's constructed correctly ( cast instead of formed sheetmetal )
