Drive pulley diameter: manual vs hydro

[wh500special 2,359]

My remaining tractors are 45 miles away and I am rummaging thru the parts in my garage looking for something…

 

What is the OD of the engine drive pulley for a typical C-series manual transaxle tractor?

 

The one I found is about 5.25” OD.  I don’t remember if I got this from a stick or a hydro.   I need one for a manual.  
 

Thanks,

Steve

That's a hydro pulley. 

Manual transmission tractor's engine pulley is more like  4" OD.

Thanks.  
 

shoot.  Back to scavenging.  
 

I know these aren’t hard to find, but this is the 1” bore for Briggs tractors so it’s a little harder.

Briggs or a Kohler small block.

This problem (looking for the right pulley) might have taken care of itself…

 

the GT1142 wouldn’t crank fast enough to start tonight and the carburetor was leaking gas pretty bad, the fuel lines from the rear were rock hard and broke when I messed with them, and the valve fell right out of the bottom of the tank when i went to open it.  
 

Rather than fix all this, I think the 11-hp Briggs might come off of there and donate its pulley to a little 7-hp Yanmar I have and which should fit right under the hood.  The engine has its own tank so I can abandon everything else.  This gets dad back to diesel only for the time being.  
 

I love Briggs engines.  Usually they can sit for years and fire right up with just a splash of fresh gas.  No points.  This one is being stubborn.  The one on the GT2500 fired first crank after I took out the battery from 2009 and replaced it.  Sucker has been sitting untouched at least 15 years.  
 

This was the first day I spent puttering around with these tractors in years.   Was

kind of fun.

Yeah it can be. I don't get any where near as much tinker time as I used to.

Been months since I had several hours of tinker time. If I can squeeze 30 minutes in every week or so I call it "mental health time". 

 

And you are correct, it is fun! 

 

And just for giggles, if you have to, the sleeves that make up 1/8 inch to use a pulley on a 1 inch shaft work very well. It comes with a taller key so the fit is nice and snug. I've used them on several Vanguard repowers. 

 

Ebay or Amazon has them for cheap in stainless steel.

I've always had good luck with them too.

I say this in all possible seriousness. 

 

You can NOT be healthy and strong for others unless you take care of yourself. 

 

We joke about tractor time... but it really is a medical necessity to be mentally stable and happy. 

 

If that's what you have available as "you time"... do it.
