I was working on a friends engine and found three pieces of a 5/16" lock washer in the engine oil pan. I can't think of what engine bolt is 5/16". Mike
Could it be parts of the Bendix spring bolt locks?
I was just thinking about that. Later Tonight the starter is coming out. THanks Mike
Well, the washer was not from the starter bolts. It must have been a stray washer from some other place or time. BUT, it has done damage. The field coil has been pulled apart and one coil has unraveled and made a mess. So, the engine has to be removed and the field coil replaced. Plus a few other items, recharge magnets clearances set etal. Mike
The crankcase lower cover bolts are 5/16.
And... this is why you don't use lock washers inside an engine. They can, and do, break over time, causing damage when the broken bits travel around, and even more damage when the bolt, formerly secured by the washer, is now essentially backed out by the thickness of the washer.
This car is what we in Wisconsin call a Bitsa car. Maybe you are familiar with the term. A bit of this car and a bit of that. The car is a 1925 roadster truck with a 1922 engine. At least that is what the engine number is. The last guy to work on the engine/transmission never used any cotter pins or safety wire, probably just what was available. It has removable ear bands, but two of them were in the wrong way. Anyway, this is a learning opportunity for the new owner. Over the next month or so, the engine/transmission will get a going over. Let you know what develops. Mike
