how to maintain the crawler bulldozer in the cold winter ?

January 15, 2024

There are many good solutions and very excellent super tips for the bulldozer users to keep the machine longtime use .

especiall in the cold winter ,if the bulldozers ,crawler excavators ,motor graders keeps well .

It help longtime use .

We offer some good tips now :

1. Maintain the fuel system and replace diesel in a timely manner
After the temperature in winter is lower than 0 ° C, the viscosity of diesel has increased, the liquidity deteriorates, it is easy to wax, and the atomization and combustion are poor, resulting in the initiative, dynamic and economic decline of diesel engines. In order to enable the diesel engine to start smoothly in winter, diesel with lower condensation points should be replaced. When using diesel, its condensate point should be 5 ° C than the ambient temperature.

When maintaining the engine, you should also clean the engine filter, replace the fuel filter, release the sewage of the oil -water separator and clean it. At the same time, it is necessary to check the work of the diesel pump to eliminate hidden dangers that may cause faults.
2. Check the leakage of the hydraulic parts

After entering the winter, the sealing parts of the bulldozer hydraulic system will cause leakage due to thermal expansion and contraction. Especially where there is an O -shaped rubber ring, the outdoor temperature may occur after the outdoor temperature continues to be lower than 0 ° C.

In order to avoid oil seepage failure in the hydraulic system, before entering the winter, a system and comprehensive inspection of the sealing of the hydraulic system must be replaced in time to replace the sealing parts of the leakage site in a timely manner.

3. Replace the engine oil

When winter arrives, the oil viscosity of the engine used in the summer will increase, the liquidity will deteriorate, the friction resistance will increase, the rotation resistance of the crankshaft will become larger, the piston and the cylinder set wear will increase, and the engine will start difficulty. The economy of fuel will be greatly reduced, so at this time everyone wants to replace the winter engine oil with good liquidity.
