Like a rubber band, tendons are under tension as they connect the muscle to the bone. If a tendon is torn or cut, the ends of the tendon will pull far apart, making it impossible for the tendon to heal on its own. Because the nerves to the fingers are also very close to the tendons, a cut may damage them, as well.escription. A torn or cut tendon in the forearm, at the wrist, in the palm, or along the finger will make it impossible to bend one or more joints in a finger. Because flexor tendons are very close to the surface of the skin, a deep cut will most likely hit a flexor tendon.
If the clutch slips (doesn't fully engage), the linkage could be grossly out of adjustment, or the clutch disk could be worn to the point of replacement. Clutch chatter is often caused by an overheated clutch (normally from slipping the clutch when starting on an incline) or from oil on the clutch disk.
Differential area relief valves must have seals to prevent leakage. Most counterbalance valves have one to three dynamic seals in them, which introduce friction, resulting in hysteresis. Friction caused by the dynamic seals makes the valve stick, causing an overshoot in pressure. The counterbalance valve then shifts to correct itself and undershoots. The result of hysteresis is bounce, loud chatter, or high-pitch squealing. Sometimes this chatter is caused by the design of the cylinder, not the counterbalance valve. The more dynamic seals in the counterbalance valve, the greater the hysteresis will be. When caused by the cylinder, no counterbalance valve in the world can reduce this chatter. Treat symptoms or the cause. Many counterbalance valves offer options to treat the symptoms. Most counterbalance valves come with a pilot ratio anywhere from 1.75:1 to 12.0:1.
