Again all I can do is talk from personal experience. We've worked on alot of the same customers machines for many years and I've never, to my knowledge, had any of the bolts I've installed break like that. Like you said all CAT's method does is to stretch the bolt after you get it to their initial torque to give it a higher torque value. Now when torquing something critical like the bolts on a head when there are several different lengths and sizes involved I can see where the torque turn technique is needed but as a friend used to say in this case it ain't rocket science. Most track shops are gonna run an electric driven impact wrench and tighten them to whatever torque they need and go with that. I've never seen one taking the time to torque them and then give them an additional x amount of degrees of turn. CAT might do it from the factory but I've never seen an independent track shop do it because it's simply too time consuming. If you'll let me know the bolt size I'll do some calling and find out what the recomended "outright" torque is for your bolts. Even with a spec if your in the ballpark you shouldn't have any problems. I know there are alot of bolts but it still shouldn't take long to do, even on your own, if you've got a way to handle the rails and pads. Personally I always laid the rails down flat, in your case a few blocks under them wouldn't hurt to give easier access to the underside to start the nuts. Once you get them laid out do like the one post suggested and make sure there are no gobs of paint, burrs, etc on either the rail or pads and then lay out all the pads on the rail. Next drop in all the bolts and then hand start the nuts. When you get this done it's just a matter of walking along with the impact and spinning them all down tight. I remember doing a set for a D6 or D7 some years back where we were cutting off the old pads and putting them on a new set of rails. If I remember right, with a helper it tooks me something like 3 days to do it all. In your case I'd about guarantee you you could knock them out in a day or two if you wanted to and felt up to it.

Today's Featured Article - Search For Spares - by Anthony West (UK). Following on from the aquisition of the old Fordson F, I was very much in need of spares. As a novice though I didn't appreciate the fact that there were so many Fordson tractors made, that all the other makes seem rare by comparison. As far as I was aware a fordson was a fordson and it was only through trial an
