Beiben oil pressure V3 accessories hand is generally oil filter blockage caused by jitter. When the filter is dirty or blocked and poor circulation of glial, oil filter and pressure is increased, the safety valve is opened, the main oil pressure increased rapidly, beiben V3 accessories oil pressure gauge pointer is put on; this safety valve and pressure reducing valve and close the main oil oil pressure decreases the oil pressure gauge, hem. When the pressure increases to a certain extent, and make the safety valve open, so repeatedly, beiben hands V3 accessories oil pressure will appear jitter, reflecting the oil pressure of main oil gallery instability. This phenomenon should replace the filter, oil table pointer jitter disappears.
