Want to buy 01 years Hebei Xuanhua 140 bulldozer, do not know how? Is there no red east 120 efficient?
11 years of equipment, depends on how the car condition?. I have been engaged in Xuanhua 140 equipment for almost 25 years. Prefer xuanggong products, fuel saving, high work efficiency, where not missing parts, convenient maintenance, transportation is relatively convenient, the failure rate is very low, Dongfanghong 120 failure rate is too high, relatively good buy accessories. Is it better to say that is better than that?!
That's out of the question. 140 is 140 horsepower, and 120 is 120 horsepower. Do you think that one is efficient?
Look at the following; 1, the degree of wear of roller chain, recency, the maintenance in the bulldozer to accounted for the largest amount of overhead. 2, there are a lot of testing time, the factory card is false, this and that. Look after the bridge behind the top right as the standard, will hang up the paint can see, the general pressure pump and the car factory date not bad days, high pressure pump, hydraulic pump have date number. 3, the vehicle structure inspection, large deformation on both sides of the triangle frame, whether there is distortion repair marks, can use a vehicle before and after the track center, whether or not the same! This is always necessary, but on the other hand, work is easy to lose track, vulnerable joint, the front and rear oil seal oil leakage. 4, engine body shell, whether there are traces of repair?. Is there any oil leakage in the whole car?. 5, gearbox in the course of operation, whether the gear lever jitter, mainly look at the 1-2 gear, advance and retreat gear. Whether or not the stalls feel relaxed and clear. 6, turn the two clutch is slipping, the main clutch is intact. Monza big shovel, with walking. If the car cannot walk, it is proved that the clutch is slipping! Looking at the cardan joint, the universal joint rotates, the steering clutch is slipping, and the universal joint does not rotate. It is the main clutch slipping. 7, each part filter check is complete, whether work?.... 8, final drive, put the oil to check whether the internal foreign body, fine iron powder is normal, put the oil hole in the lower part of the inward hook.
