    Posted: 30 Apr 2022 at 7:28am
I keep putting off dropping the front end on my D17 Series 3 to replace the pivot pin and the bushing in the bolster.  Has anyone ever had a complete failure such as the front end separating from the tractor?  Seems like the bolster would rest directly on the front axle if there is too much wear.  Tractor is not weighted and does not run a loader although it may have in the past.  I bought her used.

I have never seen one completely broken, but I have seen one worn down to the half way point.  If broken, the bolster would sit on the axle but the axle would still slide around and put stress on the back of the wishbone.
Pretty much the first thing I do with every tractor I buy is pull the front axle and inspect the pin and the bushings in the bolster.  After 60 years, they can have quite a bit of wear on them - even if they never had a loader.  It is a very often neglected part on a tractor.

And... If you do repair it, do you get a pin from AGCO or make your own?  I have seen on this forum where others have built it up with weld and ground it as best they could to get it round.  Not comfortable with that.

We had a failure of the front pivot pin on D17 S/N 2061 sometime in 1967-68? while working ground with the "big disc" --snap-coupler AC.  The front axle let go and ended up under the foot rest;nose-dived into soft furrows and immediately stopped.  Smith Farm Implement made a service call and got it fixed.  Dad doubled-nutted, and drilled holes in the nut flats and safety-wired things (holdover from Army Air Forces training) and we really watched it, especially when the tractor went over the barn concrete theshold.  No problems after that.                     R.

I had to replace the pivot pin and bushing on my '17. Noticed the pin didn't engage the bushing completely. Made 1/2 inch shims for the rear pivot bracket. Now I got full engagement. This was done over 6,000 hrs. ago and is still tight. I've looked at other '17s and they all seem to have the same problem as to the pin engagement.

I just did this repair on my D17. Welded up pin and replaced bushing, along with new shoulder bolt and hole repair and the back end of wish bone.  I also made shims and moved wishbone further forward to get more of the pin in the bushing.
If I was going to do again, I would have the machine shop make a new pin for the axle that is at least 1/2" longer. The stock pin only uses about half of the bushing length which doesn't give enough support and causes it to wear faster.

On my 170 I cut the pin off and built it up. I then machined it so it would be round and rewelded it on. If the bushing is worn through, the casting hole will be egg-shaped and the new bushing will not fit properly.

Never thought about cutting it off so that it could chucked up in a lathe after building up.  The hardness (wearability) probably isn't what it origionally was but probably acceptable for many more hours of use.  I wondered about the resulting hardness of a heat treated round pin replacement after welding it to the front axle anyway.

For what it is worth--found record of pin/bracket failure on D-17 WFE as posted above.  It was Friday, June 6, 1969.  It must have been a wet year in Delaware Township, Hancock County, Ohio.

That is some impressive repair record keeping right there!  50 years plus.  I am lucky to have last years.  Confused

Not really good machine record keeping--I was a Senior in high School in 1969 and it came from a diary entry.  Also noted that we got a day off of school that year for former President Eisenhowers Funeral--Monday, March 31, 1969--Dad and I took off the #33 Corn harvester from Gramp's WD-45, trimmed pigs, and cut up some old barn siding for kindling!  R.
