Short Cut for D14 Hyd Hose

YTSupport · May 25, 2021

I finally got around to working on the D14 PTO case hydraulic hose. It had shattered and was putting all the hydraulic oil into the PTO case. I pulled out the PTO shaft and immediately saw where it frayed and came apart.

I'm always looking for the easy way to do this sort of thing and was wondering if my plan is realistic. Looking in there, it appears to me that I could, using a long extension and a 3/4 inch 3/8s drive Crowfoot, remove it from the extension tube coming out of the ram with the case on. If successful, this would avoid pulling the PTO case off.

My thinking is that even removing the case, it will still require some sleight of hand to get the hose back up into the transport valve hole. To get it started, I'm thinking Kim could start the threads, since her hand would easily fit in the case, then I can use the Crowfoot to torque it down. It would make a big job be trivial.

Anyone tried this or have you all removed the case to do the job?

You have a plan, so try and see if it works. The downside is this.....I was always taught (and taught well) to replace the packing in the cylinder at the same time, so there is no chance of trouble a couple years down the road. With a new hose and new packing, you will never have to do it again. If you do only the hose, you may wind up removing the housing to repack the cylinder someday because you didn't do it now.

That is wise. Indeed we are agonizing over the need to split the finals and do the brakes. The PTO case is just that much more weight to balance when one side comes off if we also do that job right now. I'm am tempted to try it just to see if it can be done.

One can be reasonably sure the ram has never been touched since it was manufactured.

Thanks for the thoughts

So as not to leave this hanging, the answer is that it is not a shortcut to attempt to replace the hose without pulling the case off. The clearance inside is inadequate to get a crowfoot wrench on and actually turn it off. I would say it might be possible still, but the time required to go through the contortions of unscrewing it and somehow bending sufficiently to get it out the PTO hole exceeds the time required to remove the case and ram assembly. Once the case is pulled out, it's virtually effortless to remove the hose (as simple has breaking it loose and spinning it off.

As to the replacing the ram packing, as Dr Allis said, it was extremely loose after all these years and did need replacing. I am surprised the thing could still lift any weight. Doing the packing is easy with the case removed too.

For those who have not done this before but need to, take note that the entire ram pulls out with the case after the removal of a single pin located just under the brake rod on the right side if the transmission case.

I seldom pull the pin. I yank the housing off, pulling the rod right out of the barrel. Replace the hose and ram seals and use lots of grease and oil and slide it back together.

That describes it well, way easier than the messing around I was doing trying to save labor.

I just found the hose and packing from a place in Missouri, they had three NOS on the shelf of all things. I ask him if they always had that level of NOS stocking, but he said just on the hoses. Still pleased to find an original part.
