Guide on crank pulley?

[sahunt66]

Is there a guide on the crank pulley that insures that you get it back on in the correct position so the timing marks are still valid?

The crank pulley is keyed to the crank nose. Cant fail.

Much luck,

yes there is a key but what about the alignment of the alternator and water pump crank pulley that is factory sealed to the main crank pulley by means of a rubber gasket between the two. it can come off and mine did. do you know the correct alignment for that pulley(the one with the timing mark in it) to the pulley that is keyed in to the crank? if im not making sense dont worry bout it ill figure something out but thanks

I'm not sure about an L28 motor, but on the two piece, three row pulley that is on the front of an L24, the timing marks are on the back side (motor side) of the piece that is keyed. The front pulley is not used for timing the engine, and can go on in either of the two possible positions.

I am sure someone will correct me about the later motors...
