Zack,

The PC1698 for the 317 tractor has a section 22 that lists all the parts for the Onan conversion.

It shows a driveshaft adapter with a part number of HE190-0684 which is NLA from Deere (try it as a 190-0684 from Cummins/Onan, but I don't know if they would still have it either.) The existence of the adapter is strong evidence that the rest of the driveshaft can be reused for the most part...

Zack,

The driveshaft is the same but the flywheel adapter is different.
The Kohler uses an M83040 adapter and the Onan uses the HE190-0684 adapter. According to JD Parts, the HE190-0684 is still available. The bad news is the price is $357.

George,

I just tested something about JDParts since I have been in error twice in two days and wanted to see what the differences were. If I go to the parts catalog without logging in I expect to not get pricing -- but find that the parts sometimes show as NLA for the not logged in search results, and available if I sign in. Is there a policy of giving preference to 'members' for parts that might be getting towards end of general availability? Guess I'll not take any shortcuts in checking things in JDParts from now on...


The price on the parts to adapt the Onan to the 317 are all REALLY spendy...as I recall the plate for the engine mount HE403-2615 was several hundred dollars also (it now shows as NLA even when I am logged in...)

The 317 Onan that I sold Brandon last year was a factory parts/dealer installed engine replacement and very nicely done using all the parts called out in the section 22 of the PC1698 -- even the foam pieces that seal the blower housing and the side covers! Guess I did not appreciate at the time what was involved in the swap, since I bought the tractor with the Onan already in it.

Chuck,

There should be no difference, but when I tried to price without logging in, I got NLA for the HE190-0684 adapter. I ALWAYS log in so I never noticed this problem. John Deere's policy is to sell anything to anybody they can.
The HE403-2615 shows up as NLA but I checked at work and they had a supplier in MI. where they could maybe still get them. The dealer online parts is different from the consumer version. I have learned to always check with the dealer and not just believe the JDParts web site.

I got my shaft in the mail today and can tell it will not work at all. I don't even think it's for a 317. First the hydro pump end has splines instead of round shaft w/ a roll pin setup. Does JD make a hydro pump with splines? On the flywheel end the part that bolts onto the engine is welded onto the shaft no adapter to press out. I will get some pics posted tomorrow.

Anybody have an idea what model this would belong to?

Looks real similar to both the 316 and 318 shafts but they do not show enough detail to see if it has splines on the hydro side or not but the one I got has a grease fitting on that end so..... Man I hate ebay!!!

Will call the fella tomorrow and see if he will make it right or not.

UPDATE: I talked with the seller from ebay about the drive shaft and he said he pulled it from a 317. I explained that it would not work in mine and he agreed to take back the part and refund the money. I discussed some different options about the driveshaft with him and I really appreciated this on his part and will use him again if I get a chance. His name is Loranztrak on ebay and he is from Owingsville, KY.
