Matt, I had this problem with the power steering pump mounting bolt on an old Dodge many years ago. It would periodically break in the middle of a gratuitous burnout or a brisk acceleration run. Turned out it was due to the fact the mounting bracket for the p/s pump was "tweaked" a little such that the pulley was at an angle a few degrees off from the crank pulley. Once this was fixed, (straightend mounting bracket, it wasn't off by much by the way!) haven't broken another one, but have gone through many tires. By the way, to look at it, it was VERY difficult to see the discrepancy. Suggest taking the bracket off to see if it is flat/staight and then look at the crank pulley when revving the engine to see if it is spinning true. Best regards, Richard Osborne It snowed AGAIN last night! >>> "jennifer allyn" <gearhead.girl@xxxxxxxxxxx> 03/08/05 12:18 AM >>> OK. Here's a bit of frustration that I've been going through, for years at this point. The year is 1962. The engine is a 413 with A/C. The bolt in question is the one that holds the alternator adjusting bracket to the front of the engine (not the bolt that holds the bracket to the alternator itself). Anyway.that bolt keeps snapping off! I have to constantly drill the threaded portion out of the bolt hole. I've tried a normal bolt from a hardware store. I've tried a hardened bolt with a flat & a split washer. I've cleaned out the threads before screwing the new one in, each time. I just don't understand why the head of the bolt keeps snapping off. Anyone have any thoughts? Thanks!
