Jensen A328 PTO belt/shaft

[[email protected]]

Hi guys,

 

I need to change the belts on a Jensen A328 PTO chipper, sounds easy I know, but how on earth do you get the pto shaft off the chipper in order for me to then remove the triangle plate which exposes the belts?

 

Admittedly this is my first pto machine so I am a novice but I'm not daft and nor are my guys, we spent a morning feeling for release pins, clips, buttons, screws, a hidden chipper fairy who needed to be bribed! No luck.

 

Help us out if you can....

 

Tristan.

Only a guess but try pushing the whole collar back towards the chipper while pulling the yoke back off the shaft

Looks like an over-run clutch to me. could try searching for similar on shaft manufacturers sites.

Normally roll pin or bolt through, is the shaft on the chipper it mounts onto a normal pto spline or a plain shaft

3rd photo is from inside the cover, so I guess that's a plain shaft?

What's an over-run clutch?

How To Remove PTO Overspin Clutch

 

Overrun clutch basically a one way drive. lets tractor drive chipper, but when you disengage pto on tractor it stops the chipper driving the pto, if this makes sense, only a problem with tractors having a live pto
