[Farmall] 574 PTO

[Timothy Wafer]

A while back I posted about wanting to add a 1000 RPM PTO shaft to my IH 
574 tractor. Mine only came equipped with the 540 shaft. I acquired one 
from a used parts place, part # 3113020R1 and today I finally got around 
to installing it, or rather trying to install it.

Didn’t sound like too bad of a job from the advice I got and it indeed 
wouldn’t have been if it had fit.

The new shaft seems to be identical to the old (with the addition of the 
1000 RPM PTO end) in every respect except one. The notch in the shaft 
where the roll pin goes to hold it into the clutch pack is about a ¼” 
too far forward along with the port that would line up with the port in 
the clutch pack. This I believe is the port for hydraulic fluid to 
actuate the clutch. If I try to install it like this it binds everything up

Now I have the tractor apart and it’s the one I use to blow snow so I 
don’t want it down for too long. I paid good money for the shaft. Did 
they vary in this respect and I got the wrong one or is each one custom 
fitted in this area?

It might be possible to turn the shaft over and cut a new notch and 
drill a new port that lines up.

All suggestions are appreciated.
