    marks are on cam gear and crank gear. put mark to mark, then install your chain and gear. this is a standard on most 4 - 6 - 8 engines that use a single timing chain, and gear to gear motors .

    :idea: I callum sprockets. :rofl::rofl::rofl::rofl:
    Marks should be directly at each other, not on opposite sides of sprockets.
    Be sure to rotate the crankshaft at least two full revolutions and be sure that the marks align with each pass.
    Also, lube the sprockets and chain, either with assembly lube or with Your brand/weight of engine oil.
    When installing the front seal into the cover, fill the groove of the seal, where the round spring is, with grease to keep the spring from bouncing out of the groove. coat the bore in the cover with no.1 Permatex and also the outside diameter of the seal before driving in the seal, just to eliminate any leakage past the seals shell.
