This past week my u-joints took a dump, so I ran down to the store and picked up a couple series 6 joints since that is what I used on my 318.

After finally getting the driveshaft out I found that the joints were tiny, maybe half the size of a series 6.

 

Does anyone happen to have a drive shaft used with the 317 that has a Onan motor?? Two of the yokes on my drive shaft are trashed beyond repair.

 

Any help would be appreciated.

Hmmm? Seems Mother Deere sells a whole driveshaft, part # AM37875.

Take it to an imp repair shop or a welding shop.  They can get and even may have on hand the small U-joints in US Standard size.  Replace the entire joint and have it over with.  Lot of those small ones are used on various Ag equipment.

You have encountered one of the weak links in the 317 design when compared to the 318.   Chieffan is steering you in the right direction.  I was also thinking about a shop that builds driveshafts as an option.

The other challenge with the 317 is the limited space in the frame for the driveshaft and does not leave much room for improvement/modification.

One of the problems is one of the yokes is toast!  I don't know of any ag shops around. I do know of a welding shop in town. If I could find the correct series 6 yokes I think I could get the old ones off and weld on the new ones.

That happens to be the first hit on an internet search for the part number. 


That being said, it is hard to justify time and effort in a 317. :reading_the_manual:

6 series yokes are too big.  no one i know of on other deere sites has found a suitable replacement for the 317 other than finding a used shaft in better condition than yours.

So, if series 6 joints are too big then I would be better off just ordering the one in the link??

Well Kenny, wish me luck, I bit the bullet and ordered a new one.  I sure hope it fits.

Good luck! The 317 rear end I have here has a 5/8" shaft on the Sundstrand. Thought that was odd. Eaton's are 3/4".
