Q: I' have read from the website below that it is possible to convert the diesel engine of cars, jeeps/jeepneys, and trucks to double tank system so that they may run on both diesel fuel and filtered used vegetable oil.: Of course they can, the only difference is the size of the engines, all functions are identical.

Q: Modern 305-7 excavator oil consumption per hour, how many liters oil full load?: Modern 305-7 excavator oil consumption 0.2 liters / horsepower * hour full load.Excavator, also called excavating machinery, is a kind of earthmoving machine that uses bucket to excavate material that is higher than or lower than the machine surface and is loaded into transportation vehicle or unloaded to the stacker. Excavators are mainly made of soil, coal, sediment, and soil and rocks that have been pre - loosened.

Q: Hi does anyone knows how is a wheeled excavator steered? Is it a mechanical steering like other wheel loaders. Seems impossible because the excavator cab can do 180 about the undercarriage. I thought it must be hydraulically operated or skid steered, but my CAD teacher asked it to mechanically couple the wheels with the steering wheel. Haven't been able to figure out as to how to do it yet. Any suggestions?: I real life, it would be hydraulic, yes. If you need to couple it mechanically, I would suggest situating a rod that displaces vertically in the centre of the turntable. Linking that up to the steering wheel from the top and the wheels from the bottom should be a doddle.

Q: 1.The city of Centerville plans to dig a rectangular landfill. The landfill will have a base with dimensions 700ft by 200ft and a depth of 85ft.A)how many cubic feet of garbage will the landfill hold?C)what info do you need to determine how long the landfill can be used until it is full?D) Centerville hires an excavator to dig the hole for the landfill. How many cubic yards of dirt will he have to haul away?: A) 700 x 200 x 85 = 11,900,000 cubic feet B) Did You Forget Part B?? C) At what rate the landfill will fill up.... D) 11,900,000 cubic feet = 440,741 cubic yards ...... 3 feet = 1 yard or 27 cubic feet = 1 cubic yard

Q: My truck smokes a white or blue color, even when it is warmed up. Should I just turn the fuel up a little or is there something else like timing ect...? Also, when I start it up, sometimes it will run fine and then randomly start shaking and stall out and will be SUPER hard to start. I use this truck for mostly just towing little things such as new holland skid steers, compact tractors, mini excavators, and many other things. It has been very reliable I would just like to get this problem resolved soon during my quot;slowquot; part of the season. Thanks!: Hi White smoke is coolant. Or a cold engine. Blue is rings. Black is over fueling.

Q: I write my graduation thesis, but I don't know what the excavator work system is: Excavator is divided into the car part, get off part, and work device part, get off is mainly the walking mechanism, the car is mainly controlled. The work device, as the name suggests, is the part that works. The excavator is the big arm, the small arm, the bucket, and some have the ripper. The main or hydraulic system, main pump, felling, pilot system etc..

Q: How long approx will it take a new operator (I am going to get the feel for it first, just saying no prior expeirence) to dig this hole? (8ft deep)I am aware I have to shore it. I plan on building 2 plywood/2x4 walls across the long side of the hole and connect them across at the corners, then buildthe other 2 shorter walls and attach. Will this work good any sugestions?: If you are a first time operator, you CAN'T make a hole that size, regardless of how you attempt to shore it. Keep your cell phone handy so you can call for help from UNDER the excavator inside the hole.
