Old Hardware

Post by mike zahorik » Wed Jul 31, 2019 10:26 am

As the center main bearing cap on my 1926 engine was being tightened, a snap was heard. Turns out that the nut had cracked. Further inspection showed that the bolt threads were turned down. I have seen this on rod hardware, but this is the first time on larger stuff. The bolt was being torques to 65# at the time, but how many times in the past? The lesson here is to look at your hardware before you install it. It could be the difference between a running engine and a failure. Mike

The best thing to do on any T is use original made by Ford bolts and nuts.

Both the nut and bolt were genuine Ford Parts. Point is, even Henry's parts will fail. Mike
