Engine/Transmission (1994 - 1998) Delivery Valve Question for the old Truck Drivers

[C. Harlan]

Are Delivery Valves in the 12 Valves the same as the "Buttons" you used to be able to put into the 444, big Cam 400, KT450, and such mechanical RELIABLE motors? I was thinking about this today at work, and thought I would post a thread on it to get some responses. . Start em' Rollin!!

No. the button equivalent is the torque plate which Bosch calls a full load (fuel) stop. The similarity in function to the cam plates of yore is the reason some call the torque plate by the misnomer of "cam plate. "

So... Can I say, like the old chicken haulers once said that "I have a Button in my pump"??? Just curious. . Thanks for that info, Joe.

Ah Ha-- It's genetic! Few Cummins engines remained perfectly stock for very long. The home improvements included the "Button", and also various springs. Anybody out there remember how a turned up 335 would get a pink colored tint on the exhaust manifold and turbo? It was a sign the engine was turned up and running to the point of melting down if not driven VERY carefully. (Watch the pyrometer closer than any other gauge!) Then my VT-903, usually stock at 290 hp, which made the proud owner of a Cat 3408 V-8 so mad he quit talking to me. All I did was stay with him from a stop light for about 15 miles of rolling freeway. He was grossing 80,000 and I was grossing l02,000.







No wonder it felt so right to get into the aneroid on my '91; and to go with the TST plate on my '97.



I'm looking for a modest sticker or plate that states, "Of course it's not stock!"

... it's not just Cummins engines that refuse to stay stock.



Even my VW Beetle TDI (intercooled turbo diesel) has extrude honed injectors, straight piped exhaust and boost/EGT gauges in it.
