How to do a good job of preventing oil leaks on your forklift?

 

1. Carefully dispose of various gaskets.

Such as oil pan or valve cover, because the touch area is large, not easy to compact, simple to form oil leakage. Crankshaft oil seal leakage, oil will enter the clutch, both oil and will make the clutch plate stained slippery and burned.

 

2. Tighten the nuts according to the repair standard.

Too loose pressure can not tighten the liner will seep oil; too tight will make the metal around the screw holes bulge or will be screwed to slip resulting in oil leakage. Oil pan (case) oil drain screw plug if not tightened or back to the loose fall, the formation of a lot of simple oil loss, followed by a "burning tile holding shaft" incident.

 

3. Timely replacement of failed oil seals.

Improperly installed oil seal, journal and oil seal edge is not concentric, it is simple to swing and dump oil; some of the long-term use of rubber aging and loss of elasticity, sealing lip damage cracking or self-tightening spring failure, will lose the effect of oil sealing, should be corrected according to the standard or replacement of qualified parts.

 

4. Timely replacement of severe wear and tear of the machine parts.

For example, the cylinder liner, piston, piston ring wear to a certain extent, the incineration of high-pressure gas into the crankcase.

 

5. Repair and replace the main bearing in time.

When the main bearing and journal clearance is too large, the front and rear oil seals will lose sealing due to the impact of the crankshaft, resulting in oil leakage from the head of the crankshaft, or seepage of oil to the clutch, and then contaminate the friction plate resulting in slippage and failure of the operation.

 

6. Prevent plugging of check valves and ventilation valves.

This kind of valve hole plugging easily lead to the case temperature, pressure rise, piston movement resistance, oil consumption increase, oil and gas overflow the whole space, smooth oil consumption increase and shorten the replacement cycle. Because of the effect of air pressure difference between the case surface, often lead to sealing thin oil leakage. Should be regularly viewed, dredging, cleaning, in order to adhere to the one-way valve, ventilation valve open.

 

7. Properly solve the various types of oil pipe joint sealing.

Pipeline joint nut is often disassembled and installed, simply because of slippery wire broken buckle and loose, so that the two joints flare precision deterioration, because the cone center line does not coincide with the poor touch, because the taper is not the same and do not match, which leads to oil seepage. Should be in the grinding pipe joint and flare seal or will be thin copper clamped on the two cone surface, tighten, compact nut to ensure that the seal.

 

8. Prevent the hub from dumping oil.

When the hub bearing and cavity smooth grease is too much, or hub oil seal device is not appropriate, poor quality, aging failure and braking frequently resulting in high hub temperature and half shaft nut loosening, will lead to hub oil. Should choose to use cavity lubrication method (i.e. appropriate lubrication), dredge the ventilation holes, reasonable use of braking, strict selection of high-quality fittings, and according to the technical standards for the installation and adjustment.
