Hydraulic Piston Pumps' medium-Oil
The hydraulic piston pump uses oil processing, in the process of using hydraulic piston pump, pressure can be applied will also emitted to the first adjustment is when the high pressure side of the check window opens, find out the plunger to adjust the corresponding very column; screw loose when the very pillars of the screw nut is; if the time is late, it should spin out is when the screws a little, try again with a locking nut; if the timing advance, when the screw is to be screwed a little, try to use locking nut (this is rare); after each transfer should be very careful to slowly turn the cam to the plunger to rise to the highest point.
Then, the plunger with a screwdriver pry the rear, with a feeler (feeler) is measured when the plunger tail and gap between the screw head. This gap not less than 0.4mm, to prevent the plunger to the top of the oil valve seat, damaged two coupled parts.
If only the gap is less than 0.4mm in order to meet timing requirements, you must change with the new plunger and barrel. In the hydraulic piston pump injection timing also installed device, similar to the need to advance the ignition gasoline engine, diesel engine using high-pressure pump should run in the piston to TDC compression stroke fuel injection before the start, it can be ensured maximum fuel atomization and combustion power play.
