This can be illustrated with this math formula: Force = Pressure x Area.So if we were to push liquid at 1,000 psi into a cylinder with an end area of 2 square inches we would produce 2,000 pounds of force. If we were to enlarge the end area by using a larger diameter hydraulic cylinder with a 4 square inch end area, we would produce 4,000 pounds of force. Since the displacement of the larger cylinder will be greater, our cylinder will move slower but with greater force. Like all other forms of mechanical advantage, we trade speed for power.
The engines in our beloved garden tractors have enough power to push hydraulic oil to 2,000 psi or more. By pushing this oil into different sized hydraulic cylinders we can build almost any tool imaginable.
You may have heard of the term “grenade gears” when researching the Kohler K series engines. Even I have heard many people proclaim they throw the balance gears out when rebuilding their engine, and that they don’t do anything anyways. When asked why, people often site some anecdotal evidence of gear failure they heard through an internet forum. It seems to me that few small engine enthusiasts understand why balance gears exist, why they are important, and what causes premature failure. I hope this article can help you make an informed choice when rebuilding your engine.
The starting circuit consists of your battery, ignition switch, starter solenoid, and starter. Your ignition switch is a rotary switch that when turned to one of its 3 positions connects and disconnects certain contact terminals located on its backside. In the “start” position, it connects the Battery, Ignition, Rectifier, Accessory, and Start Terminals.
