1993 Mazda 626 6 cyl Front Wheel Drive Automatic
During a timing belt replacement, the crankshaft sprocket and both camshaft sprockets lined up properly with their respective marks when rotating the engine from the crankshaft bolt. With the old belt on, the crankshaft and camshafts rotated with relative ease. Once I removed the old belt in order to replace it, the right camshaft sprocket jumped counterclockwise almost a 1/4 of a turn on its own. When I try to turn the right camshaft sprocket clockwise back into position, it turns slightly forward then falls back to its original position. As if there is compression holding it back. The right camshaft sprocket remained aligned when this incident first occurred with the left camshaft sprocket and it continues to remain aligned although it now also exibits the same compression behavior as the left camshaft sprocket.
This is the 6 cylinder, 2.5 litre engine which is reported to be a non-interference engine although I am wondering if damage could have resulted when the left camshaft spocket initially sprang counterclockwise. Any advice would be greatly appreciated and thank you very much in advance.
have the same problem?
