## Description

Installation 1 Please check whether the engine oil is clean enough; 2 Before installing the hydraulic tappet, it should be diffused into the oil 3 Use your fingers to test the support seat in the center of the hydraulic tappet, and then select a strong support without settlement or settlement. 4 When installing, please try to prevent oil from overflowing from the inner cavity of the hydraulic tappet 5 If there is still air entering the hydraulic tappet and causing noise, please follow the "Exhaust Step" to eliminate the noise 6 During the installation process, do not try to rotate the camshaft, if it is indeed unavoidable, it should be reduced to the smallest possible extent; 7 When the camshaft needs to be rotated, the camshaft should be rotated as continuously as possible, and a single stop action should not be performed. Stop in a different position each time 8 Before starting the engine, refueling steps should be performed as much as possible to reduce the chance of air entering the hydraulic tappet; Note: There is no manual
