What happens when cavitation occurs in a hydraulic system? The consequences of cavitation in a hydraulic system can be serious. Cavitation causes metal erosion, which damages hydraulic components and contaminates the fluid. In extreme cases, cavitation can cause mechanical failure of system components. What happens if there is no hydraulic system in a John Deere? If there is no hydraulic system pressure, the hydraulic pump could be worn. The relief valve could also be damaged. For this problem, consult your John Deere dealer. For problems with the boom arms not rising or lowering correctly, it could mean that the gear...

What happens when the torque is too much? Too much tension on the bolt will cause the bolt to be stretched beyond the point of yield. The bolt will be permanently stretched. The bolt will loosen the grip on the parts that are being fastened. If the bolt is tightened again, the bolt will break. Do not reuse bolts that have been permanently stretched. What does the initial torque do on a fastener? There is an initial torque and an additional turn. The initial torque is required to bring all parts of the joint into contact. The additional turn provides...

What is the slew ring on an excavator? A slewing bearing or slew[ing] ring (also called a turntable bearing) is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slowly-oscillating loads in combination (axial, radial and moment loads), often a horizontal platform such as a conventional crane, a swing yarder, or the ... How does a slewing bearing work? Slewing bearings comprise an inner ring and an outer ring, one of which usually incorporates a gear. Together with attachment holes in both rings, they enable an optimized power transmission with a simple and quick connection between adjacent...
