there should be a snout pressed on the crank that the balancer bolts onto.

the balancer is the bottom pully.

 

the bottom pully i know it's the blancer. but the crank as a key on it. but the pully dosen't have a notch for the crank key.the bottom pully is in one peace .an the hains book shows nothing at all jus the bottom pully in two pices i don't think mine comes apart.then how do you know if it's in time?

 

the balancer & hub is a two piece design.
The hub presses onto the crank snout and bolts down using the single bolt down the center. The balancer bolts to the hub using three bolts. No, the hub does not use a key, its keyless, although the crank still has a keyway. The hub and balancer should both have an arrow cast into it somewhere. On the hub it should be between two of the three arms. On the balancer it should be on the face between two of the three arms. Basically you install the arrows on both pointing straight up (12 o'clock) when the #1 cylinder is at TDC. IIRC the keyway on the crank will end up being at about the 2 o'clock position (or is it 10 o'clock?) when #1 is at TDC.

 

thank you so much.so i just press this on over that key on the crank an be sure the key is in the 2 o'clock pisition. and the #1 is at tds. thanks alot
