D14 split

After running my new to me D14 for a few hours it looks like I’m going to have to do a split at the transmission to replace both seals on each side of the PD shaft where it exits the transmission. This is disappointing since the only leak when I tested the tractor was a known pinion or axle seal. It took several hours of running for this to show up. I’m sure this is due to the tractor sitting in the barn for 2 years and not ran. Will be a first for me at the trans of a D series other than pinion and axle seals. Will be researching the manual on the procedure.

The PD operating cross shaft can be removed without splitting the tractor. The cross shaft has an o-ring groove towards each end.

Really? That’s great news. Just looking at it appeared I would have to spit it? Hope the procedure is in a manual.

Thanks Dr Allis! Your description is better than any manual. So glad I don’t have to split it. Will get the o-rings ordered tomorrow.
Thanks to everyone who also replied.

Ordered the o-rings today, should have these 2 leaks repaired this weekend. I will give a follow up when I get it repaired. I did remove the set screw and loosened the PD stick, so its ready to be removed.

YES. Use it in the power steering and hydraulics and even the transmission and final drives.

Thank you sir. My first issue, outer plate came off fine but this one appears to be stuck. I’ve tapped around it with a small hammer. Am I just not being forceful enough? Haven’t had one of these apart before. Even tapped it with a blunt punch but no movement.

You might be able to rig up a slide hammer to one of the studs...

All good suggestions and some I thought of but too shy to try it. Just wanted to make sure I wasn’t about to do something stupid. Definitely has never been off before, the PD works great, good snap in high and low. Once I get these 2 o-rings replaced do you normally go back with just a new gasket or add a little sealant on each side of the new gasket? From previous experience I rarely find sealant on factory gaskets.

Depends on what you want to do. Depends on how damaged your gasket is when you get it apart. Zero gasket and RTV instead works fine.

Followed Dr Allis’s excellent instructions and all went well. The cover plate was more difficult to remove than I imagined. Whatever sealant they used at the factory had the plate stuck tight. It was also quite difficult to remove the old gasket and sealant from the parts once I got it off. 1 1/2 hrs later I was done. At least 30 minutes of that time was removing the gasket and sealant from the transmission and cover plate. Took my time as I had never done this procedure before and also took the time to look around inside. Now I understand how the pto coupler and shifter operate. Pretty clean inside with no sign of water entry. I made a new gasket and applied a light coat of RTV since the factory had used a sealant. Will allow it set up over night before I put fluid back in tomorrow and verify my repair was successful. I did not see any damage to the old O-rings but they were more firm than the new ones. Guessing that’s why they were leaking.
Thanks to everyone who replied and especially to Dr Allis for his excellent instructions.

We have multiple D series tractors so now I know how to repair the others if they ever leak. This forum has been a huge help for me over the years.
