It's amazing what these people can do with what they are working with. I thought it was going to be parts for some obscure engine, but Perkins has been around for a long time in the agricultural and industrial worlds. I would have actually pictured a state of the art CNC facility instead of a group in the back alley with all manual turning and measuring. Obviously they make it to spec so in the end that is what really matters.

Every time I see made in Pakistan and such on my parts from the parts store I am going wonder just where exactly it was made. I'm not knocking it, but it brings a whole new perspective to things.

We've just supplied a generator with a 3-cylinder Perkins diesel engine to a customer. I wonder if he made the crankshaft!

I've always been impressed by how those things are so incredibly resistant to fatigue ... millions and millions of cycles are performed before they show any sign of wear ... in fact, most of the vehicle fails or decays way before a crankshaft starts giving trouble

On top of that as long as there wasn't any catastrophic engine damage they can usually be shaved down a few thousands of an inch and ran again for another life time.

Plastic recycling. What a waste!
Many use of plastics ought to be banned in the first place.
Using fewer types would be a start. Why do we need milk containers made from low density polyethylene, yogurt pots from polystyrene, and soft drink bottles from polyethylene terephthalate?
