General freshen up of 1967 Ford 4100

[Pete O]

Managed to get a little more work done on the tractor this week. Frustratingly, part of it was re-doing something that had already been attacked; the shaft that I built up with epoxy way back in post #2 of this thread was leaking hydraulic oil. i did a little firewood carting with the tractor a few weeks ago and when it got warmed up, it was marking it's territory.
This shaft runs through the bottom of the rear axle casing, the three pedals pivot on it. The problem was nothing to do with the epoxy repair- which was outboard of the axle casing- but the area that the seals run on was very finely pitted. I tried polishing it in the lathe but could not get the pitting cleaned up enough to risk putting it back together a second time. The following picture shows the pitting at the seal area.

I made up a new shaft. The small end, which is where the right-hand brake pedal pivots, is 1" diameter, the rest of the shaft is 1 1/8". There's a woodruff key that takes the torque from the left-hand brake pedal- the keyway is facing down in the photo- had to use a friend's milling machine to cut the keyway as mine is out of action. I re-used the lever arm off the end of the old shaft.

After re-assembling and refilling the 38litres of hydraulic oil, I got her warmed up again today and there's no leak. Hope it stays that way, I hate doing a job twice. Three times would be a real pain.

The old mudguards were rusted out beyond repair (beyond my panelwork skills that is) so I ordered a replacement pair, they are slightly smaller than the originals so I had to fabricate a pair of brackets to raise them 75mm. Painted them up:

and made a trial fitment today, needed to confirm the brackets work before I paint those.


Next task is to remove, strip and paint the front wheels. I'll paint the mudguard mounting brackets whilst I've got the white paint going. If my calculations are correct, I'll then be able to move on to reconditioning the loader.

I've had a few family crises preventing much progress on the tractor refurb over the last little while, but I finally got a few things painted, got the tractor back on her feet and officially in a useable state, although there are still a few details to sort out. Also finally got it out of my workshop so that some other projects can get some attention. The FEL overhaul will have to wait until the weather warms up a bit here.

Very nice!!! This is the first 4100 I've saw. Thanks for the update.

Awesome restore job and a very nice tractor. We have a 1966 Ford 3000 in nice condition and a 1980 3600 that we picked up this last spring. It seems to be a good tractor but has set outside and uncovered for nearly 40 years so it looks weathered.

G'day looking good there Pete, it is a shame the quality of some of the Bare co products have slipped in the last twelve months or so, what part of vic are you in?

Nice VH....Hey Charger ! (only Aussies will know about this I suspect)

 

[greggyy]

Well, Pete....you killed it....lol.....my head hurts thinking about what you have done along with the things that most properties need doing, I have fully stripped and built a few things, but what annoys me most now is all the other things I have to do, needing glasses, and actually forgetting where I put some things down after a week or so, but I have CCTV in my shed, I might put a few more cams in

Well done, I know I would have put up with leaks, my hat is off to you.

I needed the little turnbuckle assembly on the draft contro arm but it isn稚 made anymore so I had to make one.

so, you were able to get your selector valve apart? Were there any press type covers on the valve or could you unscrew a cover to get to the Valve? Did your valve look anything like mine?

What a fine restoration and rebuild job. Excellent workmanship and sense of pride in your work. Very humbling to those of us not as capable.

Hi Slim, haven't looked in here for a while so I was surprised to see this thread back on page 1. My diverter valve is the same as yours, I thought I had posted some details of when I dismantled it but I just looked back over the thread and there's nothing on this. It was a pain to dismantle, only because all the moving parts were gunked up and seized just like the rest of the machine. There's a plug / cap in one of the openings at the top left of your photo that has to be prised off, I don't recall what was behind that particular cap but there's a shuttle valve that is supposed to move freely in one of the bores. Mine was stuck solid and I had to make a small expanding mandrel for a slide hammer to get it out. Once it was all cleaned up, the parts slide freely so you may be lucky and be able to dismantle it without having to make any special tools. If I can find any photos of mine dismantled I'll post them here.
