Draft Link Shaft Leak '76 2040

From your picture, I would replace.

I replaced the kinked one. I decided to replace the shaft due to the fact that they aren't expensive and the old one has enough wear that I think its worth it.

Replacing shaft & linked seal was probably a wise decision as it doesn't require a lot of wear on shaft to create a hyd leak.

PO (or O痴) were running with out bushings on the shaft so there is some wear. Where the Teflon rings go actually looks decent, but better still to replace for the price.

Looking back on the whole ordeal I don稚 recall any leaks back there to begin with. I知 willing to bet I either damaged the ring when I knocked the shaft out or didn稚 put the shaft back in far enough to seat it back where is should have been (leaving the slightly worn down section by the ring thus leaking). Either way, I wasn稚 getting the pin or retainer off that one end while still on the machine. Hopefully it doesn稚 leak when I put the new shaft in!

Remember to shim it up till theres no play or very little play.
Use JD shims for its harderned !

Pretty frustrated. Put in the shaft and have a leak on one side. Its the side that received the shaft from the inside vs the outside. Something I noticed was that the shaft was angled a bit low when it came up to the bushing. I used a punch and a jack stand as a fulcrum to (as best as I could) center the shaft before pushing it the rest of the way through. Obviously something went wrong because when I pulled the shaft back out there was a nice chunk missing from the teflon ring.

Now...I had the foresight to purchase an extra ring. However, I did not buy an extra o-ring. First question is, how likely is it that I damaged the o-ring as well? My thought is likely enough that I should just bite the bullet and take the hour to go buy another one at the dealer. I guess I could try to pull the o-ring to inspect for damage, if I damage it I was going to replace it anyway...if its good then I save myself some time.

What can I do to prevent this happening again?

Is there something I need to do in order to center the shaft better?

The shaft is beveled and I made sure there weren't any burrs. I also took the extra step to smooth the bevel out a little with a file and sandpaper. Should I smooth it out more? Did I install backwards? I didn't see any difference in the ends, so I don't think that's it.

Should I use the old shaft from the outside to seat the teflon ring better before trying to push the new one in again from the inside?

I'm out of ideas beyond the above, so I'll pass this one to you all now. Thanks again for the help!

Did you apply hyd oil to new shaft? I doubt o-ring is damaged. Shaft lined up correctly shouldn't require enough force when installing to cut Teflon ring.

Did you roll the seal into its place with a pinpunch ?

I did. Guess not very well.

Oh yeah, it was lubed up quite a bit. I did pull the o-ring and it's fine. I'll install the other ring this evening.

Got it

Remember to shim that shaft to allmost no sideplay !
