  • Pit Conveyor Belt Idler Arms

    Anyone know a good way to remove seized up bolt through the pit idler assembly? Some of you MUST have had these where the bolt is rigid through the inner bush due to lack of lube?
    The only way I can think of is to grind off the head of the bolt then knock it through toward the pit frame, got quite a few to do so I am looking for an easy option, any ideas? [img]/content/btubb/images/%%GRAEMLIN_URL%%/frown.gif[/img]

    There was a thread in the archives about this issue... but if you have a sawall with metal blade that should do it. I have been successful with some assemblies by using antisieze then installing the nut on the threads and striking that end with a hammer, but the sawall is the way to go.

      If you can find it, get a universal joint bearing removal clamp. It looks like a 'c' clamp with a hole ( approx 3/4" or so) on one side so you can press the bolt head through the hole. This is very easy to remove any bolt.

        Once you get it out put the bolt back in from the pit side out and don't forget the anti-seize that stuff really works.
        I would also try some PB Blaster. It is like liquid wrench but much better. Auto parts stores has it. That blaster stuff is the best thing I've found for freeing up anything.

          If you choose to cut the head off or grind it...I recomend cuting it....make sure you cut it inbetween the idler asem. and the bracket in both the front and the back..this way the idler just drops out and you wont have to beat it out in the machine....which chances are will break the rear bracket off.

            SMOKE WRENCH!!!!!!!

            Seriously, the best way to get this PITA out is the "heat and beat" method.

            Once removed, replace with quality's nylon bushing and never have to heat and beat again:

              I have a 1/2" thick piece of steel plate 1.75"x 1.25" with a 5/8 hole in the center. Back off the nut a couple threads past the end of the bolt, place the hole in the steel arbor plate over the bolt head and use a two jaw bearing puller to press out bolt.

                Sawzall with a short blade is the way to go.... 5 minutes tops...

                no banging, no breaking of the frame...

                  Thanks for your help guys - I did a couple today, on one I ground the head off & managed to knock the bolt through the back. On the other I made a tool up from a "G" type clamp, put an indent in the flat surface on the non screw end, located this over the back end of the bolt, with the other (scew) end wound up against the front of the mounting bracket it managed to break the seal & with a little to & froing & some release fluid the bolt came out the front end. With the assembly off the machine I also drilled an extra lube hole in a more accessible position, once again - thanks for your suggestions.
