bolster 860 ford

Want to know if the bolster on an 860 ford is made of steel.A member on the forum sent me a picture of the bolster on his tractor. Looks like the bolster on his tractor has the bottom part of the bolster welded to the other two parts
I need to do some welding to secure the axle pin. Threads where the pin screws into the bolster are gone. I do not have a wire feed welder. Have a
DC welder and I usually use 7018 rod if the metal is clean. Also use 6011. Would like some suggestions regarding how to weld the pin to the bolster. Type of rod and is it best to use a wire feed welder which I do not have? Would like to know if brazing would be best direction for me to proceed.

Have been unable to find a used bolster. Want to make repairs, get the tractor back in service and continue looking for a good bolster.

Yes, it's steel. Why don't you have a machine shop make you an new (weldable) nut and use the bolster you have.
 
Check Break,
Excellent idea. Your suggestion to have a machine shop make the repairs is what I would do if the tractor were mine. I am helping a friend and his wife with their tractor.I have refused to do any welding and will continue with this refusal. Have done a lot of work on the tractor. Threads gone in place where pin screws into the bolster on the inside. I posted the request as if the tractor were mine Money is an issue with them. Will use my ford jubilee with the front end loader to help remove the loader on their 860. Ordered a new pin for them and the pin lock. I was unable to determine the thread size on the new pin. 16 threads per inch. Needs machine shop work. Tacoma screw, large supplier of nuts and bolts here in Seattle unable to identify the thread. Thanks for the reply Chris
 
Literally earlier today I pulled the pivot pin off of my newly acquired 1957 850, and it should win an award for the most worn down pin ever seen. I replaced my 2N pivot pin last year. Prior owner of my 850 must have had a loader. Although my threads were OK, thinking about your problem, it may prove easiest to do away with a threaded pin replacement and go with the pivot pin replacement from a 9N tractor. The bushings are the exact same, so the pivot pin diameter will be the same as well. The locking flange is a part of the pivot pin, so there is no snap ring, but, it is kept in place using the same bolt at the bottom as our 800 series tractors. The threads in the axle are not needed so if they are stripped, the new pin will fit right through. I think this will work. Good Luck, Larry.
 
I just looked at Ford partstore. The pin outside diameter is 44.4mm, right at 1 /3/4". I don't have the pin or a thread gauge here now. I just found a 1 3/4"-12 nut at Mcmaster Carr and one at grainger same size. Auto partstore might have a wheel spindle nut that might match. Years ago I had a friend with a lathe cut threads into a big nut I put in place of that flange on the inside and tightened it down, can't remember if I welded it there or not. It's still there. It might be in the way of the pump on a loader though.
 
riveroadrat,
Checked a 1 3/4 nut at Tacoma screw. It was a fine thread with 12 tpi. Pin has 16 tpi
Have to do something besides use a nut. Nut so large it would interfere with the front crankshaft mounted hub I will not be welding the pin in place. Need to have a more qualified welder due the welding if the people I am helping with their 860 decide to weld the pin. Information I have is that the bolster is steel. I think a wire feed welder would be best to use. I do not have a wire feed welder only a DC stick welder
Tnanks for taking the time to provide information

I had a new nut made for the bolster on my 841 years ago. Welded it in place and used a new pin. You're right, the problem is $$$$. My machinist was a friend, had loads of talent and $100 bought a lot of repair.

A machine shop would cut the threads in the nut to the new pin.

I would check this out. It sounds like the easiest/cheapest way out for you. If it's a tad loose on the back, you can give it two or three tack welds on the back to just hold it still. They can be broke later if need be, to get apart.

Instead of getting a nut made, I'd get a metal plate made that looks like the one on the back. I'm sure "your" stick welds are more then strong enough to hold it, no need to have some one else do it for you.

If you ever want to know if it's steel or iron, hit it with a hand grinder. Steel will give of lots of shinny sparks, iron, not so much.

Either way Good luck with it!

Pat,
The tractor belongs to a friend of mine. Have been helping him with his 860 last few years. Money is an issue. Have done my best to take care of the many problems the tractor has had over the last few years. Have had a local welder do work for me on tractors that I own when things occur that I have felt my welding skill is inadequate. He uses my equipment to complete the work needed. He has his own portable equipment and a very nice welding shop.
Have to remove the loader and then take the front end apart. The pin is sticking out about an inch which has turned the axle loose. Will use my ford jubilee with the front end loader to disassemble his tractor. Have a new pin and lock. Thanks for the ideas to make repairs to the tractor Chris
 
All you should need to take off on the loader is the bucket itself. I have a 3000 with a loader and getting ready to R&R the bushing and pin. I have had the front end off with just the bucket off the loader, wished I had been smart enough to do the pin at that time.
 
Bob,
I was talking to Eric at Walts Tractors today. He told me the bolster for the 860 is the same as the bolster for a ford NAA
I checked the Ford/Hew Holland webside and bolsters for both tractors have the same part number. 312710
$250 for a good used one . Will see if my friend would go for this if we are unable to repair the bolster on his 860

Larry,

I was talking with Eric at Walts Tractor parts today. He told me the bolster for the NAA is the same as the bolster for the 860
Checked The Ford New Holland website and part number 312710 same part number for bolsters for the NAA and the 860. $250 for a used one from Walts Tractor Parts. Your idea of using a pin from a 9N with no threads is a good idea. Also the lock is attached to the pin.
Chris
 
I might have one out in the barn, maybe off an 841, will check but might take a day or two. The NAA axle carrier will only have one hole for mounting tin, same hole as the 600. The 860 would use the top hole as in the later axle carrier for clearance on the gas tank. Can you use the NAA carrier, sure but you will need to drill holes and a different pin was used. My email is open for questions.
 
Kirk,
Drilling holes would be for mounting tin? Pin would be the type with no threads and an end to use a bolt to hold the pin in place?
