3315 winch mounting

Post by Jerseymill » Thu Jan 31, 2019 5:27 am

I found a winch I"m looking to buy and the guy says it is missing the spline coupling.What parts are required to attach the pto to the winch? Does anyone have a parts breakdown of this section and is this part available? Thanks

Good morning,

Here is the on line Deere model/parts search link.

https://partscatalog.deere.com/jdrc/search

Search your series of 350. I assume 350 b/c the 3315 will only fit a 350. Tap on the winch section and go to gears and shafts. The splined couple is available at Deere, pricey, but available. There are some secondary market sources that offer them as well.

Here is the link to the Deere parts page. Look at #21. Part # T24774

https://partscatalog.deere.com/jdrc/sid ... gId/185363

In crawler terms, the shaft from the crawler that drives the winch is called a “winch drive”. There is a PTO shaft, also. It is a completely separate series of parts and shafts. The PTO will not mount to a winch and several other differences etc....

Best regards, Bruce

Yes I see the coupling is available through Deere, but do I need the input shaft to go into the transmission or does the winch only require the coupling to go from the winch to the transmission?

Yes you need the winch drive shaft to go in the crawler, and possibly a second coupling for the inner end. You will need to research parts as there may be some more pieces needed where the shaft comes out of the housing (bearing, seal, may be a different cover).

Further there might be another issue; one of the other fellows will have more info on this I'm sure. I seem to remember something about not all the crawlers were equipped with the internals to drive the winch drive shaft, or a PTO. I think you may need to pull the back cover and look inside to see if the drive is there to connect a shaft to. Do you have a PTO shaft now or the lever for a PTO on your floor board?

I don’t have a pto but I do have the lever on the floor board. I see that the drive shaft (t21346) is not easy find!

Time to back the crawler on a RR tie and remove the three bolts/cover to see what equipment you have in your crawler. If there is a 21 spline shaft under the cover that sticks out about 2", all you need is the coupler. If not you will need a complete winch drive (couple hundred to $500).

Hi,

On the 350, the winch drive does not have an in/out lever. That is for the PTO shaft. I don't think the winch drive shaft installs when the transmission internals are for the PTO.

The winch drive is very similar to the PTO, only difference internally is the PTO has the disconnect lever and coupling, you see the lever up in the floor, whereas the winch drive turns anytime the reverser is engaged. The only question would be, is the PTO output the same spine as the winch drive? I would assume not, but never have seen the PTO in person. And yes Stan, the 2 would be mutually exclusive of one another.

Hi,

Yes, I think the splines on the winch drive shaft are different on the inside than they are on the PTO drive shaft. They are for sure different on the outside. And, the PTO is longer. But, that might only be the part beyond the trans case.

It has been a long time since I have seen both shafts outside a machine side by side. My dad used to add the PTO on 350s for farmers when I was a kid. Hateful job, he called it. But, then he was also tearing into the trans to add those internal (infernal, he called them) parts. And, the trans reverse as well, because non PTO or Winch trans has no reverse gear. And, you need one once you have either shaft installed.

In looking at the straight 350 and the 350B parts catalogs, it appears the straight 350 had only the one transmission power shaft option for the PTO and winch. The 350 B shows 3 different options (with PTO, With reverse/no PTO, Without reverse or reverse with winch/without PTO). The coupling between the power shaft and either the PTO shaft or winch shaft is the same coupling as used between the winch and winch shaft.

There was a discussion last April on the Early Model board (1010/350 Winch) and I think that end up that a straight 350 used the same power shaft for the PTO and winch. It would look like a winch shaft, 2 couplings, as well as the right housing cover (with bearings and seal) for the shaft to come out of the large housing cover through, would be needed to set up to drive the winch. The PTO lever could be used to engage/disengage the winch in this case.

I may have missed a page or something but that's what I'm finding (if I read things right), what did I miss?

Jim

I say raise the rear end up(to prevent oil from pouring out) and let us see what is under the cover. I have thought the shaft splines were the same as a "small 1,000 RPM shaft".

If it helps, this is the winch drive shaft
