 Topic: D17 series 3 steering
Posted: 26 Jul 2024 at 2:50pm |

was moving round bales, should say unloading round bales, backing away from trailer when I heard a loud pop. No steering, set bale on ground, back up tractor some more had steering at this point. move tractor forward to pickup bale, with weight placed on front of tractor again, no steering. setting bale back on ground, backing up to remove spears from bale, steering is working. No visible signs of anything broken on outside, fluid level good, pump is working, no fluid leaking onto ground. this is a wide front tractor. where might i start looking first?

This is wild guess and probably isnt the problem. Id look at the front axle pivot pin and see if it broke

Does it turn right and left? If not, my bet would be a broken ram rack.

unfortunatley, when this happened I was tiring to get things caught up before shoulder surgery. now that my arm is in a sling for the next 6 weeks I can't crawl around like I used to. teaching my left arm to do simple tasks is a big learning curve. The doctor said I have to stay clean and not do anything with or on my shoulder. back to the tractor it only will turn slighty one direction. i was able to drive it to the shop by making wide sweeping turns. thanks rick

Let's establish what the actual complaint is. "No steering" to me means the steering wheel spins and nothing happens to the front wheels. I doubt that this is what's going on, but could be. HARD steering would mean if you are strong enough, with two hands, you can steer it but manually, no power assist. If the power steering rack has a sheared pin, it would steer HARD to the left and seem to be OK to the right. A broken front axle pivot pin could be UNABLE to steer either way, right or left. So what is it ???

okay doc, my nurse did not see me climb under the tractor this morning, so I was able to see I hope is the problem. The pivot pin that goes in the front weight casting is basically nonexistent. The front of the tractor is resting on the axle by a thread. so when i can get out and remove tie rods, tires, spindle housings and axle from tractor I will take the main axle housing to the welding shop and have a new pin welded on. this leads to the next question on the measurements of the pin diameter and length, cold rolled or hot. what size is bronze bushing in casting.

The pin is approximately 1-1/4” OD, about 4-1/4” long… the bushing is 1-1/4” ID and about 1-5/8” OD, about 2 inches long. The bushing is available still, I believe, but pricey! I made my own
bushing using a bronze spring pin bushing that was made for a freightliner front suspension that cost less than $20 and is long enough to make 2 bushings out of it. I could dig up the part number if you need it. I had to rebuild the pivot pin and front support casting on mine this spring.
I imagine the pin is originally hardened. I would opt for cold rolled since it would probably be a cleaner smoother material to start with. If you use the spring pin bushing that I suggested, you could probably order the mating spring pin to make your axle pivot out of, and it would be hardened… and will fit the bushing properly. Just cut both to the correct length…

Once you get it apart, the pin is the easy part. It's the casting that is likely all wallowed out where the bushing belongs that is harder to repair.

thanks for the info, i agree the casting hole will be the the the interesting fix. will look in scrape pile first to see what pcs are left from another tractor. next thing is to get thru all of the rehab, hopefully by christmas. have lots of work in front and piling up 4 plus brake jobs. one pto seal split job, make 2 seat adapters for 175, last but not lest finish putting and looking pump for one seventy narrow. bottom line is you got to to enjoy it and have a spouse that tolerates it, i mean me.
