  • I'm about to replace worn parts on front swivel pin, on late Ford 600, and not sure what I'm getting into and best method to do it.
    Currently I have a 3/4" threaded bar thru the bushen pin, with a pipe larger then pin and pull it forward, with all attached yet.
    Once I pulled the pin, I was hoping there would be enough up/down of axle to pull rear bushing and then front.
    Is ther a better way, like removing radiator, then pull pin and then unbolt assembly from block and do a bench job?
    Only bushings avaikable at steiner.
    Was going to make center pin if worn and feasibility.
    Advice appreciated.mail open

  • Got the pin out. Its threaded on back mount. Keeper bolted on front mount keeps it from turning loose. Just have to remove stop and unscreW from exosed slots. Poorly design original uses tHE threaded portion for the bearing support. Wear is at least 1/16 to 1/8' DEEP IN THIS THREADED AREA. Onlt about 1/8" screwe in rear mount . Pin needs to be about 1/2" longer so bearing is on unthreaded portion. I may get by with just having a new pin made. Need to mic bearings yet. Even appears there may be enough space to pull bearing, without tearing front apart. Would have been nice if I had a machanics book.
    ts appreciated. Live and learn!!

  • plan
  • Drop front support assy. Press out bearings on bench job. Clean out threaded area. Extend old support pin 1/2' by welding pipe on with new slots cut. Screw in pin 1/2" more. wore spot will be threaded hole and new full bearing support.
    Does good to sleep on project as solution comes in dream!!!

  • Miss diagnos and change plan
  • The pin and threads in the mount were hammered up an down for 1/8" slop.The bearing was only .30 worn. Complete fix would require new support and new pin.
    Farmerised it instead. Removed front clip and pounded pin in about 1/4" and bolted over front slot on pin instead of in slot.
    Engineering error was not length of pin in threads, but two soft of metal of both pin and threaded support. I have also noted slop in pins and mount of wishbone rod pins and axle.
    Not going to worry about it any more as should be good enough for my lifetime.Steers alright

    Should read drill to 23/32" or 47/64 and ream to .750 and then press in.
    Error was made as my other option was to drill all to 25/52" and buy 20 English bolt 120 MM long. This option wold still allow the softer cast axle to wear again as compare to bronze bushing and be with a couple thousand play.
    I did the above on hydraulic arm wear. Had to heat knuckle with acetylene and cool in outdoor furnace to aneal softer to drill.
    cost of bushed axle would have been about $180.

  • Re: Miss diagnos and change plan
  • Took axle to machine shop as hole for pins attaching to wishbone were elongated 1/8". front to back on bottom hole. Told them to recenter on elongated portion so they could make the hole round to accept 3/4" brass bushings.Took the center pivot pin and new bushing for it. and new 3/4" to 5/8" brass bushing to shove in hole. 5/8" pins not worn as they are harden. Axle was the softist.
    Needed to machine as front pivot pin must be square to vertical pins, so wishbone fits in the ball socket on transmission.
    Plan on using worn pivot pin, and will weld it in place . Let next owner worry about it. Probably will last the life of the tractor and then they can cut it out if necessary,
    Good to have slept on this job to DO IT RIGHT
