Cat & IH did insist on bearings that were <br> only Cat & IH inclusive, whereas AC crawlers that used more Timken style<br> bearings, could be sourced from any bearing supply co. Five times cheaper<br> than Cat Or IH equivalents.<br> An interesting aside was that, rarely was there a need for machining with<br> AC, Cat or, IH as regards remedial repair of parts.

Only source was the manufacturer.<br> Another delight was the spaghetti extruder, it had a 50hp motor driving <br> the extruder through reduction gears, every every shaft was a nominal size +<br> a 1/16" Guess where the bearings had to come from. It had one bad design <br> fault in that the heaviest reduction had no hunting teeth, and it had some<br> very bad wear patterns revealed on dismantling, had a blank forged in Australia,<br> it was about 600mm with a 152mm face. :-)<br> > <br> > I've found that engineers don't always make stuff weird so you have to <br> > buy from them, its often so you don't make a substitution that <br> > compromises the design.
