I have a JD2640 with an oil leak on the shaft where the 2pt arms on the rear axle housing. It appears this shaft goes all the way through the rear axle housing. Any suggestions on how to repair the leak?

The shaft is for "load sensing" for load and depth control of the 3-point hitch. There's a seal at each side of the main tractor frame casting.
If you go to www.jdparts.com and click on "Previous Parts Catalog" and look up the parts catalog for your 2640 you can see parts breakdowns and look up parts numbers.
I suggest posting at the DEERE-specific Forum lower down on the page. I have replaced many of those seals in larger tractors, but never a 2640, so I can't comment on any more specific details.

Leak is on what JD engineers called the load control shaft. O needs to drain hyd oil to R&R shaft. Place L/D control lever under seat in "D" before removing shaft. Heat neoprene seal in warm water before attempting to install. Shim side to side motion from shaft when draft links are installed with washers as required.

I'll guess to utilize Boling Machine shop seals one must replace bushings @ $95 per set. I was taught when employed by a JD dealer as a service manager to only replace L/D bushings if worn enough to justify replacement. I've never had a problem with leakage when utilizing JD L/D seals on JD utility tractors if shaft was not worn too much & shaft side play was eliminated with shim washers.
I agree Bolings bushings/seals for 3010/4010/3020/4020 are far superior to JD seals but I've never seen 1st hand Bolings seals for a JD 20-55 series utility tractor L/D shaft

Greetings Tx Jim, this is off topic but I didn't have a way to contact you. Could I entice you (with pay of course) to tune up a
JD 346 square baler and change or sharpen the knives? I'm not that far from you.
Thanks !
