With the Spring Festival is approaching, people are busy around the concern and preparation, "New Year" northern drought situation in the south cold continues, the farmers are determined to be prepared for the coming year.
Turn over to buy a TV refrigerator, cast bronze clothes and other New Year's custom, have to buy agricultural agricultural services market "technology New Year" for the production efficiency and the family income this year to achieve "win-win" lay a solid foundation. dry bushing Right now, bronze bushing do "science and technology New Year" has become a new fashion in rural counties.
Buy popular science books, learn scientific farming. Maintenance of agricultural machinery, many people to explore their own experiences: for example, some parts are not subject to structural limitations,plain bearing the assembly will be installed when the slightest mistake counter, to agricultural machinery failed to stay hidden. Therefore, they have to attract attention during assembly.
sleeve bushing 1. Cylinder pad hole,DU bushing and must make it with the body,bushing cylinder head oil passages on the corresponding holes in order to avoid valve mechanism on the cylinder head off oil caused due to friction. Road Hole and the pros and cons of oil-like shape to the material to determine the head: brass bushing For the aluminum cylinder head, cylinder head should be towards the side of the curling cylinder; for the cast iron cylinder head,Mould guide plate cylinder head should be towards the head side of curling .
2. Piston and piston rings and other mark up arrow top of the piston, should be marked under the direction of installation; no tags, it should be top of the piston vortex pits or pit next to the small gap toward the side of the injector, to ensure that the gas uniformly mixed. Piston ring assembly, the top "on", plastic bushing UP and other markers should be up; top of the ring unmarked distortion, and its inner circle notch or chamfer should be facing down; chrome ring (shell lights) should be installed In the first piston ring groove, the ring opening 120 to 180 degrees should be staggered to ensure the sealing effect.
3. Rod and rod cap horizontal diesel engine connecting rod is split by 45 degrees, the section should be down in order to improve the forces connecting rod bolts. Connecting rod cap and connecting rod is a matching process, the assembly should be to match the mark in the same side of the connecting rod bearings to ensure roundness, cylindrical compliance requirements.
4. Main bearing caps, main bearing cap bearing or bush bearing and the body are paired Boring, should be paired token condemnation are not free to exchange or change the direction of the assembly, so as not to damage the main bearing hole concentricity and dimensional accuracy. A hole in the bush or the bush, should be aligned with bearing, bushing bore holes on the corresponding oil path to ensure the smooth flow of oil.
5. Cylinder head bolts if the bolt of a coarse thread, the other end of the fine thread, coarse thread end should be screwed into the body; if the two ends of the fine pitch bolts should be screwed into one end of the shorter body to ensure that the cylinder head can compress.
6. Oil pump and oil pump rotor by the planet, and should be chamfered towards the outer rotor pump, so as not to pump their own oil in the pump oil circulation and reduce stress. Wear a crescent-shaped plug nozzle axis positioning slots should be aligned with the positioning holes on the pump, the plunger on the mark (or back to the tank) should be installed facing up, so as to avoid non-oil or diesel, "Speed."
7. Shaft and drive shaft at both ends of the transmission chain of the fork should be in the same plane in order to avoid torsional vibration and damage to transmission components. Transmission chain with spring clamp and should be made open end of the chain movement direction and the opposite direction to avoid collision in the sport by shedding.
8. Wheel wheel marked with the up arrow should be to point to the forward direction of rotation when the tire; no marks, from the motorcycle rear wheel, the "eight" shape or "people" shaped pattern of the top should be facing up .
