How do you install push rod valve to camshaft of Ba Isuzu diesel engine?

To install the push rod valve to the camshaft of a Ba Isuzu diesel engine, first ensure the engine is at Top Dead Center (TDC) on the compression stroke for the cylinder being worked on. Align the push rod with the lifter and insert it into the lifter bore, ensuring it seats properly. Carefully position the rocker arm over the push rod and align it with the valve stem, then secure it in place by tightening the rocker arm bolts to the manufacturer’s specified torque. Finally, recheck the clearance and adjust if necessary before reassembling any removed components.
