Please see my thread ‘FSMajor wheel wobble’ which discusses the problems I subsequently had with wheel wobble and getting the correct kingpins. I hope this will prove useful.

Please see my other thread as I have now solved my kingpin problem and it may be beneficial to someone who is about to change their kingpins. It could be a bit of a lottery getting satisfactory kingpins but it’s worth noting the kingpin numbers that I mention and the suppliers.

Problem solved! As suspected the APUKOnline left hand kingpin was not as it should be. The splines were slightly rotated (probably 6 degrees or so) from where they should have been. I have just installed the Agriline left hand kingpin and the front wheels are now parallel. So there are good kingpins...

I noted that both kingpins from APUKOnline were stamped ‘FNM977’. I had assumed they were the same from Agriline as the left hand kingpin bore that signature. Just opened the right hand one and it is ‘FNM981’. Good sign? Not sure what the number signifies. If you imagine a line from the centre of th...

I will try the original left hand kingpin and see if the toe-in is reduced, preferably eliminated. The steering arm on that side is 3/8” further from the tyre than the right hand one (this has the effect of causing toe-in). By my reckoning, if I could somehow turn that steering arm towards the tyre ...

I read somewhere that for each front weight attached to the tractor there should be an increase of 3psi in the front tyre pressures. This applies for up to 3 weights at least. Can anyone confirm that please and possible tell me where it is stipulated?

Yes, the wheel wobble is still there but possibly at a higher speed. Will have to put the old left hand kingpin in to check the toe in and if that has little or no effect then I will probably have to bodge it. I did ask Matt at Agriline if all their Kingpins bore the same manufacturing number. Don’t...

I will do that Sandy but I don’t expect the left hand one to be sufficiently different to offset the toe-in. I am beginning to suspect that this discrepancy has always been present. It will be interesting to receive your dimensions for comparison and to see if the wheel wobble is still present.

I have now got a pair of Agriline kingpins. I installed the right hand one and the toe in was still the same. I then changed it for the original kingpin and toe in was still the same. I then put the APUKOnline kingpin back in and set the wheels to the narrowest setting. Again the toe in is still the...

Hi Sandy. Yes it would be high but I have seen a picture of an industrial tractor where the front attachment sweeps down to a low level and that is the type of thing I am looking for. This particular attachment is actually bolted each side of the tractor. A front attachment will give much better con...

I am looking for a car type tow hitch to attach to the front of my Super Major. This to help manoeuvre my caravan and trailers.

I spoke to Jim Fletcher of J.E.F. Engineering and he told me that years ago components were made in a particular country (can’t remember where) and the quality was consistent, unlike nowadays where it varies between suppliers and within suppliers. He also told me of a problem which has caused kingpi...

I intend to call one or two tractor repair/refurbishment specialists next week to see what their experience is regarding kingpin replacement and I know someone locally who may have second-hand spindles. I will take my vernier gauge with me. I have still not decided how to temporarily set the wheels ...

I have a thread running entitled ‘FSMajor wheel wobble’ which provides some background to my request. Does any member of the forum have regular/any dealings with replacing kingpins. I am looking to purchase genuine kingpins from somewhere that are as per the originals such that they don’t present th...

Thanks Sandy. Not sure which way to go on this job now. One kingpin needed replacement as the splines are worn and was quite sloppy. The associated steering arm was okay and that’s why I sent it back. I tried pinching up the steering arm but was afraid it might fracture. Any suggestions here please?...

Thanks for staying with this discussion Sandy. I have just looked at the spindle arms and I think they are original EnFo ones. I will try to confirm with part numbers. Bear in mind that before I replaced the kingpins things appeared to be okay, not that I needed to look this closely before. The dist...

I did purchase new spindle arms from Agriline but discovered the sloppiness was due to a worn kingpin so I sent them back. Wanted to keep things original too. Surely there are some decent kingpins out there. I do rate Sparex, probably due to their price! Any other recommendations please? I have just...

Thanks for your replies. Is it likely that the toe in is causing the wheel wobble? As I noted in another thread on my axle overhaul, I was aware that the spindle arms were not ‘symmetrical’ and with my son’s help we moved one spindle arm by one spline. This required a bit of hammering to get the loc...

I should say that wheel wobble wasn’t a problem before I overhauled the front axle and there is no play in the new wheel bearings. If I could be certain of getting a pair of kingpins that, when installed, would result in the front wheels being parallel then I would gladly throw away the ones that I ...

I appreciate your reply. I know you told me before about the 0.025” clearance but I am unsure where this measurement is taken and its significance here. The rubber seals are installed at the top of the kingpins. The wheels turn freely with little sideplay. Do you have experience of inaccurate tie ro...

I overhauled the front axle and have only recently taken it out on the road. I was very disappointed to find it developed a wheel wobble (both wheels) as I got up to a reasonable speed. As kingpins seem to be in short supply I chose APUKOnline as supplier. Mistake? I struggled to fit them and to mai...

Doing some maintenance on the front axle of my Super Major threw up a few questions and points of interest. The first challenge was to undo the 6 nuts on the stub axles. Tried heat, WD40, etc and finally resorted to a slogging spanner which made short work of that task. The next challenge is to get ...

I am looking for a magazine published in 2010, I believe, by Peter D. Simpson entitled Fordson Major 1945 - 1964. The words “Tractor Data” appear in the top left hand corner. ISBN numbers are 13 : 9781906167486 or 10 : 1906167486. Published by Mortons Media Group Ltd. I think you would call this a B...
