Symptoms of Failure

When the components within the 4642.199.055 LOOSE PARTS kit begin to degrade, operators may notice several distinct failure modes. Oil leaks around the transmission housing are the most common symptom, often caused by worn sealing rings or damaged threaded bushings. Gear slipping under load can occur if the screw plugs or cover plates become loose, allowing pressure loss in the hydraulic circuits. Abnormal vibration or noise from the bell housing typically indicates that the grooved studs or hexagon screws have fatigued. Finally, difficulty maintaining transmission fluid levels without visible external leaks suggests internal seal failure within the housing assembly.
