Fruita CO | An instruction sheet should come with the gasket set if you get it from JD, if not, who knows, but there are several different ways to torque the head bolts, depending on the marks on the bolt heads & the block casting number. I wouldn't advise trying it w/o that sheet and/or the tech manual...the latest bolts are torque-turn, but if you use that method on the wrong block, you'll pull the threads out of the block. Also, the torque-turn bolts can't be re-used, you throw them away & get new ones. It's possible the bolt that broke was a torque-turn that got retorqued...may be a good idea to replace all of them even if they're not T_T. All the above stuff about checking for cracks, liner protrusion, (.001-.004), etc. is good, just don't slap a new gasket on & smoke the old bolts down w/o knowing what you've got....466 head bolts were a real snake pit... | |
