Before starting the vehicle, the diesel engine must add enough coolant to avoid water shortage. Can not add cold water in the body when the temperature is too high, so as not to block crack. Winter outdoor low temperature water (or parking note with antifreeze), to prevent Baotou beiben heavy duty truck accessories Donglie cylinder; vehicle operation must maintain a specified temperature, an engine cooling water, not too hot or too cold; check the oil level should start before the amount of oil required to scale to machine on the dipstick, add or replace when the engine maintenance; to strictly abide by the rules, to avoid unnecessary damage to human.
Baotou beiben cylinder fittings flatness error exceeds the limit, will cause the cylinder pad pressing not caused by Water Leakage, air and oil leakage and ablation phenomenon. Two maintenance can be used to dial indicator check: will a bowl support on the platform, the block plane and parallel platform, namely the four diagonal angle find two pairs of high.
The mobile platform along the dial gauge holder being tested in the plane of the maximum and minimum reading indicator as the difference of flatness. Also available on the foot is detected on the plane, the gap with a feeler plug two plane asked to check, the maximum value is inserted into the gap feeler flatness. The technical requirements are: the cylinder body on the plane flatness error, each 50mm length should not be less than 0.05mm. Cast iron cylinder six cylinder engine length is not more than 0.30mm, the cylinder of the machine does not exceed 0.20mm: aluminum alloy cylinder engine does not exceed 0.50mm, four cylinder machine does not exceed 0.30mm.
Flatness error if Baotou beiben parts cylinder plane ultra limited, must be repaired. If local bulge, grind or whetstone available fine file Hsiuping; slightly larger sag can be used for grinding or milling method to repair, but the machining allowance should not be too large, otherwise it will make the compression ratio increase caused by the explosion.
