  1. More fuel without extra air means black smoke. It's all about optimums, intake air filter cleanliness, air intake temperature, height above or below sea level, fuel delivery pressure, both low to the pump and high to the injectors, injection time and duration, and compression peak pressure. Then the person on the controls makes it talk or not. I only used to get 10 out of a Scania 420 auto running on 6 axles pulling a curtain sider over the hump to Manchester from the North East, It was usually fully freighted both ways. I could get 17 out of a manual ranger plus splitter 460 CF Daf running nearly the same route pulling a reefer but only on 5 axles running 38 tonnes down and 22 back. With a 420 Scania auto it was 12. With a C6SFL in a Vickers Vigor I used to use between 5 and 7 gallons per hour on dozer work, it was about the same pulling a 9/11 box. Depending on ground conditions.

  2. I did not think you would get that kind of millage running at that weight. To get a like for like comparison an identical rig with a turbo or supercharger would have to run the same route on the same day. Todays trucks use a lot of fuel running ancillary's and the exhaust system. One of the Premium's I drove would sound the warning buzzer and put stop immediately for no reason, very disconcerting while motorway driving. When I got used to It was spot a pothole and give it a run through and off it went, it was like that from new. Any C6FSL that I drove in plant got through the work but were noted for being thirsty.   

  3. A friend has asked if these parts have any value. He thinks they are off a para bike. There are a few more bits but I cannot get the pictures across. They are from his friends fathers estate that they are clearing.

  4. Going from a rusty memory first thing in is a spring then separator with seals on each end opposite ways around then the first plunger with a spring over it then another seal facing in over then a circlip. But it is 40 plus years since I was inside one. It's a split system part of the cylinder works the front brakes and part works the rear brakes. All of the wheels need the brakes adjusting up correctly to get a firm pedal feel with full air pressure.
