743 lower boom piviots for the bobtach what is the fix for the tapered pin holes being wollered out . 743 i was given has about 5000 hrs on it ..still runs good ..a little hard to start but new glow plugs and about 15 seconds gets it going . the bolts that hold the pins in keep coming loose i re tighten but i just know the hole are ruined .this has most likely been addressed here before ...do you have a link please ..thanks..jim
 
Construction Tool Parts 1 800 500 5221 , they sell a-taper bushings , you drill a hole thru the boom arm to turn the wollowed out a-taper into a round hole then insert the bushing and weld it

Thats close to what i had to do on mine. The previous owner drilled the tapers out and installed bolts..... I made a tapered boss and welded it into the arms. The hardest part is to get them in perfect alignment. I'm not sure how to recommend how to get them lined up. Hopefully you can put the bobtach in with new bushings and use that to hold them straight. Tack weld it and make sure its free to rotate.
Good luck with it all!
