Show Valve Grinding Made Hard In some overhead-valve engines valve grinding is made a harder task than it should be, because when the valves are removed the owner dismantles the rocker arm assembly. In most engines this is not necessary, because the rocker arm can be disconnected from the vertical rod. pushed one side and the valve removed. In engines using cages, this is particularly easy, though most owners go to the trouble of dismantling dis-mantling the rocker arm assembly. To push the rocker arm aside use a flat wrench with a pair of pliers at one jaw to twist with. |
