I offered to help a friend fix his Kubota L35 backhoe/loader. The problem is that the link-pin for loader bucket auto-leveling lever is hard to move and wont relax and sticks in position causing the bucket to fully tip down when the boom is raised. The root cause is a bad grease zerk that didnt pass grease into the sleeve and pin. This has been fixed but the pin is still too hard to move, it should really be loose and spin freely by hand.
Probably the best solution is to remove the pin from the sleeve and give it a good cleaning and polishing but to gain access to remove the pin, 4 hoses have to be removed from the FEL control valve and the valve removed from the frame etc. I'd much prefer not to do al that.
Any suggestions to loosen that pin without removing it from the sleeve? I've gotten some grease to go thru and put oil on the ends. I've moved it back/forth thru the 90 degree swing space but it still isnt freed up to where its easy to move.
I was wondering about heating it with a arc welder by creating a short circuit with the stick on the end of the pin, not sure if this works or is asking for more trouble .
Thanks.
