Thanks for your detailed explanation--I understand your approach to solving the problem much better now! Now that you've pointed it out, it is obvious there would be lots of wear on the frame bores. Perhaps you need a horizontal boring machine with a table large enough to hold half a tractor! More seriously, maybe you could make a portable line boring machine

Yes you have to do what is right for you. It has been a long long time since I used nitrogen and thinking about it now I would feel uncomfortable using it in a one man shop. No need to introduce another hazard! Keep the videos coming.

Yeah, thanks! Machine where I can set half of tractor is horizontal borer by Stanko 2650Ф1 or portal milling machine by Stanko 6М616... Yes, portable line boring machine toos is good equipment - this will be one of My future projects.

Hey FD87, this is another beautiful solution that you have made here but if replacing worn bores is becoming your speciality then perhaps you could think about investing in a liquid nitrogen tank for shrink fitting bushes?

What a huge amount of work to do all that boring and make all those expanding bushings!

Well, I CAN set the middle pivot [piece with two main bolt bore WITH bronze bushing, (100kg)] on machine table, but I CAN'T set a half of tractor [tractor front frame - 4 bores on line, there set a bolts what hold tractor together, (over 1,5 t)] on My machine table. Same bolt will be slide in bronze bushing, but expander bushes will be set in the frame bores what I can't to work. The bores in tractor frame is beat up and worn, so this is the reason to make "expander bushing and bolt repair kit".

Thanks! Liquid nitrogen tank? No, no- too expensive here and here I can't get liquid nitrogen- need license. Also I have limited space into My workshop - no place for it. Better I buy one more good great lathe or great size milling machine for that money. For fitting the "repair bushes" I can tu use ice, fire, oil, screw, great hammer and anoyher ways how to get fit the bush. I always to calculate mearures for bushing - over-measures (from 0,03mm to 1mm) and accuracy (from 0,1mm to 0,01mm).

The edge angle 15deg is too sharp - by screws can't get to pull together, but angle 10deg is too flat - too much space takes this construction. I use 13deg angle.

+FactoryDragon87 Ураааа...!!! ))) Была слабая надежда, что ты понимаешь по русски и она оправдалась...))) Расскажи пожалуйста за размеры.. Конус точишь под углом 13 градусов, а какие размеры берёшь за основу длинны пальца..??? На сколько миллиметров нужно точить втулку длиннее...??? Было бы неплохо если бы заснял на видио весь процесс...))) Отличная получилась работа, главное, что очень нужная...))) Респект...!!!)))

Привет +Иван Васильевич ! Я живу в Латвий и русский язык надо знать. Ну по размерам там очень просто: част рабочая - размер внутрений между расточкам (между ухим стреле екскаватора), част коничиская - толшена или длина неподвижноий сидения палеца, длина палеца - наружний размер обих расточкам (примерно ухи стрела екскаватора). А диаметр втулки - средная размер изношений расточка. А вот тогда етие коничиское бтулочки ест 5....10мм длинее чем длина расточка в ухи в стрела одноий сторин. И бить очен внимателним - етие длини можно отличаться. Прости за мой плохоий язик. Если тебя какие вопроси - иши меня. Спасибо!

+FactoryDragon87 Спасибо...))) Я тебя прекрасно понял..))) Когда то, очень давно, когда еще был Советский Союз, я служил в армии вместе с ребятами-латышами, с некоторыми до сих пор общаемся и дружим..))) Теперь очень рад знакомству с тобой..)))
