    2305 John Deere Driveshaft Removal, U- Joint Replacement

    Felt ambitious today. Read all the threads I could find on the subject. So off I go...
    My 2305 just turned 400hrs. Don't believe the U-joints were ever lubed. Attempted to do so recently but had my doubts concerning the grease penetration.

    Tools needed for removal and install-
    Circlip pliers with 6" or longer handle and 90 degree bent nose.
    Flat round punch about 8" long but 6" can be held with pliers
    Hammer
    Lights
    Screw driver to rotate driveshaft

    Tools needed for U-joint assembly-
    Small circlip pliers, straight nose.
    Small screw driver
    Hammer
    Press or hammer/punches/sockets etc.
    Grease gun
    Emory paper to clean up races
    Large channel locks to remove joint caps.
    Cleaner

    Parts needed-
    New circlips for u-joints and front driveshaft. I was able to reuse the old ones. Best to have a spare.
    U-joint kits from JD (2)


    Figured it would be easier to get it up on my car lift...

    Next step was to orient the driveshaft in anticipation of removing the front circlip. Then knocking out the roll-pin which resides under the clip.

    To remove the circlip a circlip plier about 6" long with 90degree bent nose is needed.

    Open the circlip and push forward toward engine.

    Rotate the drive shaft to expose the roll pin. The pin is about 3/16 diameter.

    The JD exploded parts manual shows a small pin within the roll pin. Mine did not have one. Anyways they both get knocked out together.

    Using a punch (needs to be about 8" long) knock the pin up and out.

    Now the Driveshaft is free. There is nothing holding the rear of the shaft onto the Trans spline (no circlip or roll-pins).

    Now the drizeshaft can be pushed rearward until it bottoms out against the fan.

    The front of the driveshaft will be clear of the Engine splines.

    Push the front of the driveshaft upward to clear the engine splines then push forward.

    Now the rear of the driveshaft will drop down and the shaft can be extracted by moving rearward.

    Now time to change out the u-joints. I used a cheap hydraulic press. Best to watch a youtube video on how to remove and install u-joints. Or take to a driveshaft shop.

    JD sells the u-joint kit. Circlips are not included!

    The circlips on the u-joints are the external type. You will need a small circlip plier to compress them and remove.

    Good job and nice write up about what I remember seeing when BIL and myself removed driveshaft to change bracket holding the fan. What a PIA getting the final clip on after putting the driveshaft back in place. Shop foreman ( good friend) stopped with longer needle nose pliers had in back on within 10-15secs. I had tried guessing close to 2 1/2-3 hrs..

    After installing the u-joints I greased them. They come preloaded with grease. The grease is clear almost like vaseline.

    The caps on the old u-joints had dots of grease where I had attempted to grease them, but no grease made it into the needle bearings.

    Make sure you mark all the orientations of front, rear, and note proper orientation of grease fittings etc.

    Now the driveshaft can be installed in reverse order.

    From rear- up and forward with shaft.

    Over the top of the engine shaft

    Then push the shaft rearward onto the trans shaft.

    Then orient the roll pin hole and move the shaft forward onto the engine shaft. (this was the toughest part of install. Hard to see and get the splines to match up)

    Then drive in the roll-pin

    Squeeze the Circlip and slide rearward into the driveshaft groove.

    Total time was about 4 hrs.

    Removal was quick.
    Changing the u-joints out was a pita
    Installation was quick with exception of getting the front splines to match up

    Gene- Think the secret is to open the circlip just enough to move it forward out of the groove. Then just let it hang on the engine shaft.
    If you try to squeeze it and push it over the driveshaft it certainly will be difficult.

    And really that roll pin is in there pretty darn good, doubt it is ever going to just "fly out"....makes you wonder why (as many have asked) there is not a bolt and nut?

    This is awesome thank you for sharing.

    Big thing now is to convince the spousal unit that I need a car lift since that look like it made the process much easier. My plan os to put up on jack stands and and use a creeper. Also all my blades are intact on my fan but I would assume it gets brittle over time like all plastics so is it best to replace since the shaft is pulled?
