A friend kindly lent me these items to share. They represent the T era and may be fun to see.

I find it interesting that Harley-Davidson started with a belt final drive, switched to a chain drive for decades, then recognized that belt drive was better and returned to their original design. American auto manufacturers did the same thing with wheels and tires; first they had large-diameter wheels with small tires, then gradually went to smaller and smaller wheels until they got to 13" diameter with big tires, now they are going to larger and larger-diameter wheels with small tires. Whooda thunk it?

John, early belt drives were never as strong as chain drives developed later. The change was one of serviceability/durability. The return to quieter, cleaner, easier maintenance belt drives is a result of different technology and materials which can handle the power of new engines. Just like belt drive camshafts on cars.

In saying that Allan, I can remember when Fiat, Alfa's and even ford cortina cam belts seen the life of the engine, but by today's standards the modern car requires replacing as low 80K and big dollars to do so.

The main reason timing belts are much stronger today than when the early ones came about, is Kevlar. The inclusion of Kevlar makes the present timing belts nearly indestructible.

Sooo, now that the new timing belts are far superior to older ones, the manufacturers are going back to timing chains, go figure?????

just sayin'

I'm glad they went back to chains, wish they'd go back to just gears. I went through a couple belts on a 92 Pontiac. It's a pain to change them. I bought an 04 Chevy Cavalier and thought I'd put on a new belt to be safe before it broke and was glad to find out it had a chain.
