What are the automotive engines you know that used safety wiring on bolts and or nuts as original from the factory ? Cotter pins don’t count, lol…
and the brits made everything to fall apart, so there's lots of safety wire on them. Cam bearing retaining bolts, oil intake tube, cam tensioner, flywheel, oil pump cover, etc. Keep in mind on a Ford T, there are no bolt torque specs in the shop manual, at all. Safety wire was kind of necessary on things that could come apart. Even the oil pan nuts all had cotter pins on them.
Almost every nut and bolt on a model t is wired or cotter pinned roads were pretty rough and not the smoothest running engine
Lots of Euro stuff was safety wired from the factory. Continental motors had some safety wired components. Fly wheels, rod bolts for example. I am not sure what years, but I have pulled some older ones down for overhaul and found safety wire. I have seen safety wired updraft carbs several old motors with updraft carbs. Cannot put my finger on a brand name. Lots of older aircraft motors were safety wired too.
@squirrel , yup many a times I pulled my pliers out of the drawer to safety wire stuff back together . shims snd safety wire! Don’t think the brits could of built a car without either of these, oh and ****ty gaskets and sealing surfaces are great engineering marvels of there time as well
Years ago I rebuilt. 63 MGB engine and ch***is and can’t remember any wire… But maybe I just ignored using it…
go back a few years earlier, you'll find it. They did change fastener types in the mid 50s on MGs, when they finally got away from the XPAG engine. On a T, there are lots and lots of cotter pins, not so much safety wire. Wire is used where there are bolts, and no nuts, and most of the parts use nuts. The main bearing caps are held in with bolts and nuts, there's a cotter pin on the nuts that are hidden in the middle of the block between cylinders 2-3, for example. The flywheel is held on with bolts, which are safety wired. There are a few others, but it's been a couple years since I did one, and I can't remember as well as I used to.
If I remember correctly, on the Model A ,safety wire is on the torque tube bolts to the rear end housing, the flywheel bolts and the four motor mount bolts.
Having grown up with GM musclecars where there are few cotter pins (ok, I know, ch***is parts have 'em) and no safety wire, I was shocked when I took apart my flathead!!! I had to borrow my brother's safety wire pliers. He works on airplanes, his pliers are well used
