Many in the start of the JiShou agricultural engine, open the throttle started, and ignore the engine starts before the crankshaft idling. Open the throttle started the stillness of the engine, especially cold car, the axis and bearing the oil flow has between all off, the axis of the bearing surface onto brass bushing bearing, if the suddenly in the shaft bearings inside the rotation, will produce dry friction (metal and metal directly friction) or half dry friction, make each axis and bearing and other sports a speed up, even can arise "wear holding shaft" accident. So the engine before initiating must first cranking plain bearing a moment, until the oil pump started to work, and the oil, every word oil filled with axes and bearing a small amount of oil into between the friction surface again after the start, plasic bushing you can avoid "holding shaft"Mould guide plate accident, and can greatly extend the life of the hijackers hair.
Now is s195hx diesel engine as an example to show a link to do this work methods: first the throttle on "stop for" position, pull up the reduced pressure handle,DU bushing diesel engine in the reduced pressure wave form, and turn the crankshaft, and gradually to speed up the cover of the cylinder head, observe the red buoy oil pressure indicator whether rising. If that rises, the oil pump, the normal work way already full of oil, oil can open throttle (that is, at the end), to speed up the direction board moved, and let go of the crankshaft decompression, engine that is activated. After the engine starts with speed for a moment, and then into work.
