You do have all the spark plugs out don't you? If plugs out and engine turns easily with socket on front crank pulley nut then, the weighed arm should be fairly steady unless you have some debris in the grooves if one of the 6 cogged pulleys - 4 cams, aux drive and crank.Ok so the belt is on and im currently tensioning following the tsb procedure. I have a few questions...
Is the weighted arm supposed to move up and down as i rotate the crank? I know that the tsb says just be sure the arm doesnt fall bellow horizontal.
