Moving the injection pump with anything other than force you can apply with both hands may over tighten the injection pump belt. There is a better method using tools 5199 and 5201. Make sure the engine is at TDC by looking for the mark on the flexplate or flywheel. Using tool 5199 to hold the rear camshaft sprocket, loosen the nut holding the rear camshaft sprocket on the camshaft. The torque value is 73 ft lbs here, it's very tight. Tool 5201 is used with a 1/2" drive bar or ratchet to loosen the nut. Loosen the nut, keeping in mind that it's very tight. Once it is loose, retighten finger tight. You are now going to rotate the sprocket in the normal direction of rotation ( the camshaft must remain stationary). Rotate the sprocket with tool 5199 or your hand, keeping in mind that you are rotating the injection pump belt and the sprocket on the injection pump. While you are rotating the camshaft sprocket, watch the needle on the dial indicator, once you reach the value you are looking for, tighten the rear camshaft sprocket nut , making sure your injection pump timing stays in the right place. Once you have the nut tight enough it won't move get ready to retorque to 73 ft lbs, this is much torque for a hard to reach area. This method takes rotating the injection pump by hand out of the equation. Makes sure your injection pump timing belt is not too tight. Address that first before setting the injection pump timing.
