Heat and pounding worked, did bugger the 3/4 threads on one side hopefully can clean up with a die
Yes the bolt is captured in the frame of the loader which then slides into the mount attached to the tractor. The pin courses thru both and the bolt head, when the nut is tightened it stress the pin securing it in place. There is currently no tension anywhere in the construct, simply just cannot get the pin to slide out of the bolt head, which I can barely see as it is smack in the middle of the whole apparatus. Additionally the pin is pulled out from the inside (towards the engine) so to use some sort of puller I would have to cut the head of the pin off and possibly render the system in usable if I could not finish the job. So at this point more penetrant, and then heating the treads of the bolt you can see in the picture to try and expand the head some, followed by vigorous pounding with a sledge.
Question about applying heat. The problem area is smack in the middle of the loader bracket. The pin courses through the bolt head. Would I not want to heat the bolt to try and expand it rather than heat the pin?
There is no stress or load on the pin. The bolt pin combo rattle freely in the bracket. Problem appears to be fusion of the pin inside the head of the bolt. I will explore suggestions.
thanksattached is pic of the problem, 3/4 bolt locks the pin in the bracket. Cannot for the life of me get the pin out.
Sorry was not clear enough, it is the pins that are stuck. I got the nuts off the bolts easy but cant drive the pins out
thanksFinally made it back to the camp. As advised by Bob, thanks Bob, changed the injector pump oil. About 10 oz of something between diesel fuel and 30 wt oil came out. Replaced with 15-40 oil used for engine and wouldn’t you know it within minutes was running well. Normal throttle control, no runaway at all. My pump has a small dip stick, and with the rec 4 oz of oil did not register. Put in 2 more and was about half way between marks. Tractor runs great. Only residual issue is fuel cut off/kill mechanism sticks in the kill position. It actually has been doing this for some time. Moves to shut off no problem, but spring return is not reliable. No amount of spray lube on the spring and lever arm change much. It may be getting a little better but not enough time to be sure. So now I have a machine that runs well but is nothing more than a diesel wheelbarrow used to move things around the yard. NO 4 WHEEL DRIVE. I have done everything I can think of. Slugs made from hardened steel rod in place of ball bearings , judicious use of 4 wheel drive, nothing seem to hold up and at my camp 4 wheel is a must. Has anyone heard of a permanent connection between front and back, something welded. I know this may damage gears and make future repair harder, but as I said right now I have a big wheel barrow and nothing else, so what to loose.
thankspics are to big, will not post. basically made a bracket out of some old galvanized strap and 3/16 all thread and secured to a bolt holding fuel filter mount. has worked fine for a long time.
