Oil leaks in trucks or any vehicle can result in loss of lubrication for the engine, and results quickly in damage to the engine. Similarly, transmission or brake fluid leaks are also very damaging to the operation of the vehicle. So, if a leak starts, you need to get it fixed.
Does it have a manual transmission with a hydraulic clutch ?
Both! The gas engine would take oil then the log splitter that runs the hydraulics would take a specific hydraulic fluid. Its best to go by what the manufacture says
There is no hydraulic fluid in the transmission. However, there is hydraulic fluid in the clutch system. If the clutch fluid reservoir is empty it would cause clutch not to operate.
designed for hydraulic jack perhaps power steering fluid would work Brake fluid Ruins pump
Brake fluid is a type of hydraulic fluid with very specific properties. You would have to check the compatibility of the particular fluid with the components in your system. This would include the cylinders, seals, hoses, and any other internal components exposed to the fluid. The best thing is to use the exact fluid that the system manufacture specifies.
No, air is compressible, hydraulic fluid is not. It would be analogous to trying to use a giant rubber band instead of a steel crowbar to pry things apart!
Transmissions are hydraulic just like your brake system or power steering system. Without transmission fluid you would have no hydraulic pressure for it to operate nor would you have lubrication. Trans fluid also has cleaners in it to clean your transmission as clutches, and gears wearaccumulate inside.
No. Only hydraulic oil can be used in hydraulic jacks. Hydraulic oil is compressed (a requirement for use in hydraulic cylinders) so that there are no air or other gases dissolved in it. Before adding hydraulic fluid to the jack, be certain that the fluid has been sitting for at least 24 hours to avoid introducing air into the hydraulic fluid in the chamber.You should be able to purchase hydraulic oil (sometimes it will be labeled "Hydraulic Jack Oil/Fluid or Jack Oil/Fluid) in small or large quantities, inexpensively, at any auto parts store worthy of the name. It can also be purchased at some Walmarts and any heavy equipment supply stores.
The most commonly used hydraulic fluids are oils, so yes they are flammable. However, most any fluid COULD be used as a hydraulic fluid depending on the system design requirements. So it really depends on exactly what type of fluid is being used whether it is flammable or not. Water is a "hydraulic fluid" and is not flammable. Under NFPA standards, petroleum-based hydraulic fluids are not "flammable" if their flash point is above 100o F (37.8o C); they would be "combustible". NFPA 1 (2009): 3.3.153.2 Definition of Flammable Liquid
For the TS Astra with hydraulic-electric power steering, it takes a Pentosin CHF fluid. A couple of equivalents I have come across include Castrol Hydraulic System Mineral Oil Plus, and Penrite LDAS fluid.
Pneumatic = Air! There are brake systems that use a combination of both pneumatic and hydraulic components. In those combination braking systems you would use the hydraulic brake fluid that the manufacture specifies.
The transmission fluid capacity for your truck, automatic transmission would be 3 quarts.
