How to deal with automobile shock absorber oil spill failure

Mar 22, 2017

Automobile shock absorber in case of oil leakage, shock absorbers, will no doubtbe a very dangerous thing. Then, once a leak is found, it is necessary to make timely remedial measures. Focused examinations in the ruptured oil seal gaskets, gasket is damaged, water storage cylinder, check whether these parts appear nut loose.If the oil spill, first tighten the cylinder nut, shock absorber oil spill, the failure of oilseal, gasket may be damaged should be replaced with new seals. If you still cannot eliminate the oil spill should pull the vibration reduction, if there is a credit card or do not weigh a further check that the clearance between the piston and the cylinder is too large, shock absorber piston rod bent, surface of the piston rod and cylinder for scratches or marks.

If the damper is not leaking, you should check the shock absorber connecting pins,connecting rods, connecting hole, rubber bushings are damaged, unsoldering, cracking or shedding it. If the examination was normal, it should be further broken down shock absorbers, check that the clearance between the piston and cylinder is too large, cylinder there is no injury, valve seal is good, valve flap and valve seat fitting is tight, tension spring and damper for soft or broken, according to repair or change of approach to the situation to fix.

In addition, appear in the actual use made a noise of shock absorber failure, this is mainly due to the shock absorber collide with the leaf springs, frame, or axis, pad is damaged or fall off and boot for shock absorber tube deformation, oil causes such as inadequate, the reasons should be identified and repaired.

Check shock absorber repair work should be carried out on a special test rig test,when the frequencies of resistance at 100 ± 1mm, its resistance shall conform to the provisions of the access to stroke and compression stroke. Drive maximum resistance to 392~588N; Dongfeng vehicle access to travel a maximum resistance of 2450~3038N, compression stroke maximum resistance to 490~686N. If no test conditions, we also can used a experience practices, that with a iron wear into shock absorber bottom rings within, with double feet stepped on live its ends, hands hold Shang rings reciprocating pulled 2~4 times, dang up pulled Shi resistance is big, down pressure Shi not was effort, and stretch of resistance and repair Qian compared has recovery, no empty drive sense, is showed that shock absorber basic normal.
