Engine System, Diesel246Service Manual – CS7000SpecificationsFuel Pump;• Fuel Pressure 2.5 - 4 PSI• Fuel Volume - 0.5 Gallons per minuteGlow Plugs• Resistance - Approx. 0.9 ohms• Current Draw - Approx. 12 - 13 Amps. (As the glow plugs heat up, resistance increases and currentdecreases)Engine Compression541 to 597 psi (3.73 to 4.11 MPa) with an allowable limit of 327 psi (2.26 MPa). Difference among Cylinders -10% or less.Engine Oil Capacity1.5 US Gallons (5.7L)Engine Oil TypeRefer to the following table for the suitable American Petroleum Institute (API) classification of engine oilaccording to the engine type (with internal EGR, external EGR or non-EGR) and the Fuel Type Used : (LowSulfur, Ultra Low Sulfur or High Sulfur Fuels).Fuel Type Engine oil classification (API classification)Engines with non-EGREngines with internal EGREngines with external EGRHigh Sulfur Fuel[0.05 % (500 ppm) ≤Sulfur Content <0.50 % (5000 ppm)]CF(If the “CF-4, CG-4, CH-4, or CI-4” engineoil is used with a high-sulfur fuel, change theengine oil at shorter intervals.(approximatelyhalf))Low Sulfur Fuel[Sulfur Content <0.05 % (500 ppm)] orUltra Low Sulfur Fuel[Sulfur Content <0.0015 % (15 ppm)]CF, CF-4, CG-4, CH-4 or CI-4 CF or CI-4(Class CF-4, CG-4 and CH-4engine oilscannot be used on EGR typeengines.)• CJ-4 classification oil is intended for use in engines equipped with DPF (Diesel Particulate Filter) and isNot Recommended for use in Kubota E3 specification engines.
