This is a California thing.
This state, in all of its infinite wisdom will come to our yard and verify that a particular machine runs and that the serial numbers are good. I believe that we also have to work or operate the machine so many hours a year. Im not sure what the numbers are.....maybe 1500 - 3000 hrs. Anyways, the motors are pulled and a hole is torched into the block making sure it takes out the crank. Trust me, the good parts of an engine are pulled and used to keep some of the others alive. Whats left over is either cut up for scrap or saved to be used somewhere else. Tires are used on other machines, and of course other parts are used for this and that and , so on and so fourth. I'm not gonna talk about it because it's all bull crap like this state, it's laws and the garbage that results from its completely moronic policies. Example... repowered B's. Sure they run a little better....bla bla bla but thanks to the unreal emissions rules, they run real hot. All of them. Puller fans instead of pusher fans which heats up the cab cooking the operator. It has everything to do with how and where the air to air cooler is located in relation to the radiator and oil coolers. In open cab machines, it heats up the cab and cooks the fool running it. In my case, my leg simply rubbing up against the shift tower gets burned. This is after 2 days.
A design issue. The repowered B's have them and the K's are full of them . I don't know about the G's as we only have one. The K... I don't like them. It's always something. Little things. pain in the ass things. Our K only says 657 on the side. They are still
proto-types and are constantly being redesigned to fix the many design issues. Having to add DPF... what a joke....just like this state. I can hardly wait for the zero emissions ( electric) scrapers to come out. I imagine they will be the W (woke) series. it will happen...
