I was so impressed with the mechanics of that Willy's. In virtually all modern vehicles there is a timing chain that moves the valves. In some cheap cars they are plastic
That Willy's didn't have a timing chain. It had two huge, like 7" steel gears with a plumbing pipe over them shooting oil on them so it would last longer than Nancy Pelosi. And it did. For all I know, that thing may still be on the road.
It would make a lousy family car or highway car because it was built so good and strong that it made a lot of noise. Steel is noisier than plastic.
But it was a working vehicle. Imagine if I tried to plow anything with my New Jeep Compass. There would be $2,000.00 worth of damage for every hundred bucks I made.
A few years ago I had a snow blower, I sometimes put it in the back of the Willy's to get into tough places. It was about 40 years old and you couldn't kill it. I could pick up a cinder block in it and it would just either crush the block, or stop. It was all giant, steel gears.
I needed to change the drive chain for the front "screw" that throws the snow and I went to a snow blower/bicycle store. The guy looked but couldn't find a matching chain because it was so old. I said, just give me the closest one. He said "I have been doing this for 20 years and I say, it won't fit and you can't bring it back" I told him that my socks were 20 years old and that 40 year old snow blower has so much play in it that any chain would fit and I don't need the receipt because if I say it will fit, it will fit. Of course it fit perfectly. (He was a Jiboni)
My new snow blower, which was all plastic with no gears but it comes with a handful of stupid "sheer Pins" which are little iron pins that are supposed to break before you break the machine. Just make the machine so it won't break and you are set to go, what's wrong with that concept?
I don't need a snow blower here as it is a condo so they get somebody to plow it, but I am sure that new machine I had would only last a few seasons, and that is only if it never snowed.
Maybe the Doctor can put a sheer pin in my knee.
