T the change of the platen adjustment is often due to the end of the valve seat wear in the running, the rocker arm and the gap between t linking piece. So commonly found in radial clearance tightly adjust t the platen. T d plate after adjustment is usually in the injector plunger, then can then adjust the valve clearance. T platen adjustment steps are as follows: 1) Loosen the valve t-shaped plate adjusting screw lock nut, and screw bolt. 2) With your fingers gently press rocker arm in t linking piece on the contact surface, make the t contact pressure plate and the valve rod. 3) Budge t linking piece adjusting screw down until it comes into contact with the valve rod 3. 4) Because t have space between the clamp lever and catheter, and for compensation adjustment screw loose, for the new t plate and ducts, adjusting screw should be turned into 20 & deg; 。 To wear t-shaped plate and ducts, must turn into 30 & deg; 。 5) Keep adjusting screw, screw lock nut, tightening torque is 34 ~ 41 N, m. 6) With a feeler check t plate end face and the clearance between the valve spring seat, the minimum clearance value is o. 64mm。
