    Default John Deere 420 loader quick hitch rebuild

    Hello Again:
    The quick hitch on my John Deere FEL was almost worn out. The lower pin holes had walled out to the point that it was difficult to change attachments without getting off the tractor. I repaired the pin holes by cutting the holes large enough to accept a pin boss made from DOM tubing and welding it in. The DOM tubing provided a nice new 1 inch hole with more wear surface.

    I posted a few picture on this site and I posted a video on Youtube. Here are the links:

    The reason it wore out like that is properly one of the pins that go through side to side rod was broken. Now be careful if both pins break the rod can actually fall out.

    I'm not sure which wear spot you are referring to but the only broken/missing keeper pins were on the rod that connects the quick hitch parts. I had replaced the missing keeper pins with bolts. The bolts allowed too much play. I have fixed that problem by drilling out the holes and inserting tight fitting spring pins.
    The worn out enlarged holes were caused by bad enginering. The sides without pin bosses enlarged. The sides with pin bosses did not wear out. I covered this all pretty thoroughly in the Youtube video

    I did basically the same thing to my 420 loader.
    I don't have any pictures of the loader, but here is the same fix I did on my backhoe. I used round stock, and drilled 1-inch holes in the larger round stock.

    Yes we are talking about the same pins. I got tired of mine breaking so I drill out the rod and quick hitch and installed the next size larger. I have to agree it is a piss poor design if the rod was a litttle longer they could have put a pin on both sides of the quick hitch or better yet they could have fixed it staight from the factory the same way you fixed yours. Maybe I will have to do mine soon ,they not as worn as your but better to fix it now
    Oh yea great job on the fixes

    Took a picture of mine this morning. I didn't weld all the way around, will be easier to grind off and replace at a latter date.

    I agree on the bad engineering. Your pivot holes had more wear than
    my ex-rental project tractor!

    I had a lot of wear in the locator pin holes on the bkt, too. See photo on
    post 456 here:
    http://www.tractorbynet.com/forums/p...ebuild-12.html
    It is the one marked 1.3". Was yours pretty worn, too? Fixing that one
    made a huge difference in the up/down slop in the QA brackets.

    I considered the DOM tubing approach for both, but decided to make
    the holes smaller by welding. I think your approach should last longer,
    but you can not do the DOM method on the locator pins.

    BTW, I watched your videos on the FEL cyl upgrades, MARS....nice job!
