KT (A) -1150 engine how to check the shock absorbers
Clean
1. Rubber shock absorber can be washed in hot soapy water
2. Viscous damper can be used to remove rust cleaning agents, dirt or grease, such as a defective engine shock absorber found upon inspection, the installation of new shock absorbers
Rubber shock absorber
Rubber shock absorber is a folder with rubber-coated metal parts, the engine shock absorber is connected to the engine in an appropriate manner, you can protect the engine
1. Check the damper for cracks, check the engine rubber parts for cracks and aging, the latter two would weaken the role off Vibration
2. Check the damper valley and inertia components are aligned on the mark, if the deviation exceeds 1.59 mm, the waste absorber
3. Check shock absorber inertia “outer plate” placed within the margin of the poor, per inch (25.4 mm) radius shall be more than 0.13 mm, which do not meet the above standard engine shock absorbers, to be scrapped.
Viscous damper
1. Check whether a defective shock absorber (such as crack), if defective, it should be scrapped
2. With the SKD-NF type coloring agent or similar product sprayed on the shock absorber, the engine shock absorber into the furnace, heated to 93 °C
3. The shock absorber removed from the furnace and check for leakage of liquid or traces of oil, if the presence of oil, scrap shock absorber
4. Four evenly spaced from the engine absorber surface, clear front and rear surface of the paint, dirt and dust, fine sand with paint solvents and cleaning cloth surface
5. In step 4 above washed four surfaces, with a micrometer to measure and record engine shock absorber thickness, about 3.1 mm from the outer edge of the readings taken
6. If four readings differ by more than 0.25 mm, replace the damper
Shock absorber mounting flange
1. Check the shock absorber mounting screws threaded holes
2. The maximum difference between mounting flanges placed in the guide shaft diameter measured at the shoulder, the total meter readings not more than 0.10 mm, the flange surface at a radius of 69.85 mm when measured, placed not more than 0.08 mm difference . The readings were taken in the post-test engineassembly, check the surface of the pendulum is poor, the engine crankshaft must be maintained after the first thrust or thrust of the limit position.
