conn rods and flywheel nuts

[Author nameAuthor names are only available to PAS members.]

Conn rods on my 1930 Model A engine have drilled bolts and regular hex nuts. Should the bolts be wired across the caps?

Flywheel to crank bolts are also drilled, and I’ve mislaid the nuts. Should they be castle nuts, secured with cotter pins, or regular or castle nuts secured by wiring?

Thanks for your advice.

Rods should have castle nuts with cotter pins crank should be wired. I like to wire 2 and 2 not all four in series.

Thanks for the reply. The crank has the four cap screws on the front to hold the timing gear sprocket. I will wire those as you suggest. At the rear there are six bolts with drilled thread ends that hold the flywheel. I found the castle nuts, and plan to wire them with one wire around the circle. I will replace the regular nuts on the connrods with castle nuts and wire them across the cap, just like the main bearings.

Best of luck Mr Romberg.
