Remove the pump timing mark mess how to do?

If, for any reason, the mark is misplaced or the pump is removed at the end of the mark, the most reliable way is to remove the water tank, bellows, and open the timing gear chamber cover and re-mark according to the "X, Y, Z" mark on each transmission gear Assembly, but this method annoying, heavy workload, generally minimize the use of
Another way is:
(1) The first diesel engine to the first cylinder before compression top 14 º ~ 16 º (14 º ~ 16 º before the top dead center in the crankshaft belt tray engraved lines, where the symbol "I" that top dead center, symbol "Ⅱ" Said before the top dead center 14º ~ 16º), see Figure (217)
(2) Put the oil pump flange on the engine and draw a line on the flange of the arrow on the window. The arrow on the engine inspection window will be "copied" on the oil pump flange Put the flange gear back to the pump
(3) Install the pre-short stroke measuring device, look for the pre-stroke end point of the first cylinder (cylinder B) according to the working steering of the oil pump (when the oil supply starts), when the position of the pre-stroke end point is found, immediately on the transmission gear of the oil pump Is engraved on the flange marking, so that has been found in the pump gear on the first cylinder and flange engraved mark corresponding to the beginning of the oil supply
(4) The helical gear with the first song after the first crank symbols, the pump installed as long as the mark on the engine view window on the arrow

Tungsten Carbide Roll Rings

Tungsten Carbide Roll Rings, also known as hard alloy roller ring, has been widely used in the rolling production of high-speed wire, bar, threaded steel, seamless steel pipes, etc. due to its good wear resistance, high-temperature hardness, heat fatigue resistance, thermal conductivity, and high strength.
The Tungsten Carbide Roll Rings we produce mostly come in two series: WC Co and WC Co Ni Cr, with Co and Co Ni Cr as binders ranging from 6wt% to 30wt%. From a usage perspective, hard alloy rollers have good comprehensive mechanical properties, with a bending strength of over 2200 MPa and an impact toughness of (4-6) × At 10 ^ 6J/m ^ 2, the Rockwell hardness (HRA) can reach 78~90. During the high-speed wire rolling process, the single groove steel passing amount is much higher than that of cold hard cast iron or high-speed steel rollers.
