I have the black socket only 1/2 inch drive, I use on the tractor wheel nuts. 3/4 drive on my truck but its a ratchet wrench, no impact wrench. I guess the big gun stuff will do it. If my pulley bar idea doesn't work I will see if I can borrow a big impact wrench. Thanks

36mm socket with 16mm thread 159 foot pounds

I do, the tractor was in high gear, handbrake, and I also have a chain holding the pulley but it was all still turning, even the back wheels were moving a bit so I got scared that I would ruin a spline or damage the crank so I was going to make this tool, a steel plate to bolt in to the three...

I do understand Dan but why so tight, I have 4 foot bar and it wont crack, but i haven't used it against the pulley tool, I will make up. The heat Gehorn mentioned free up tight nuts from expansion, I have used oxy before to do this with nuts, the tractor has lived on a property a few miles from...

No I meant use freezing. they use liquid nitrogen to remove pins sleeves etc, probably not on this it would make the bolt too brittle and bust. My temperature here where i live is 39c lately. That's a 102F. I realize some threads worry about their tractors being frozen, if only I could have nice...

I am willing to try any penetrant but nothing will reach the thread I wouldn't think because it has such a wide washer as part of the hex head. it would need to penetrate 3/4 of an inch to even get to the thread. I can only see heat or freezing to free up the threads. Maybe the new pulley holder...

I call it a nut when it comes off a thread and its a bolt if the thread is on the hex head. I was just saying both because some pulleys have nuts and the crank has a thread on it. Mine has a thread in to the crank with a hex head bolt that holds the pulley on. It has a wide fixed flange/ washer...

I will have a look today but like you say no clear evidence of locktitie just the blue tractor paint. I am thinking the same about heating up the bolt head a bit then try, then a bit more and try etc. Will try penetrant but I cant see anything freeing this up, it would be a world cure. I think...

No I didnt say the nut moves I said the breaker bar moves an 1/8 turn until the gears take up, so I meant the whole lot is turning, pulley, crank, through clutch to wheels then its springy tight, too tight to go on, I was scared of stripping something because I have a long breaker bar. If it...

Yes thank you Dan for your input. I will see if I can borrow an impact wrench if it doesn't work with the tool I will make. Its very tight so I don't want to strip it either, the impact wrench would be the better choice first. I could have put more pressure on the breaker bar but its so tight I...

I don't have either tool but I just had a look and I can make a long steel plate that I can drill so the three pulley bolts will bolt it up then hole saw a hole through the center so I can get the socket on and breaker bar. If it still doesn't free and its still tight I will try a bit of heat on...

Thanks Dan, you are talking about an impact driver that you hit with a hammer aren't you and it turns as you hit it? That's what we call it in Australia. The other tool you might be talking about, here we call a rattle gun. That's what the tire shop guys use to put your car wheel nuts on?

Thanks Dan, I was scared of any impact on the front of the crank might damage something. I know an impact wrench forces it to turn but doesn't it also have some forward impact? I may overly worry that the main bearing or the thrust bearings on the crank could get damaged? Barrie

I have a supertight pully bolt that wont free up. Front end is off and engine is on tractor fully supported. I have put it in high gear, handbrake on, a chain around the pulley to take some of the turning force, with rubber under to protect where the fan belt rides. I have hit down the washer...

Not used to forums, how do i private message you?

Thank you just the same, help is so much appreciated when you get stuck with a rare tractor over here. I have only seen one rear end at a wreckers, nothing left on it, and a couple of whole ones on the other side of the country, too expensive. I think a lot more got shipped to the states. I do...

Thank you so much, that's very kind of you. I will do as much research this week and let you know. Do you have a Kubota supplier that have stock on these old tractor parts? basically need the sets I mentioned and then head gasket overhaul kit one Tappet and a couple of rocker bushes so far. I...

That's okay thanks Dan, I imagine they will be dearer over here, I will check. Do Kumar Brothers sell the OEM parts do you know? I know about Messicks but I was told they wont ship out of the States? $145 AUD plus freight is okay for 6 journals, Just that the rings will be closer to about $800...

Well the OEM rings are $85 per set priced in the USA, that's over a $120 AUD, so six times that. I haven't checked a price for the rod bearings, i guess they wouldn't be as much. The Kubota dealers here see you coming. I will check a few out but I think I could add 50% on to the American...

Thanks Dan I did see that as I browsed the site, I saw they have the south east Asia office in China and I emailed them before I realized. They will probably forward it to their English speaking counterparts. Have you have any experience with the prices of their parts? Barrie
