i just got a set of ur crank pulley standard recently, and the question is i have my engine remove out of the shell so i can see the pulley in front of me but what are the main point i need to take very careful to install it? or just unscrew it put it on and screw it back in. thx bro

 

Use a pulley puller to pull the crank pulley off.

Make sure that there is no burrs on the new crank pulley and/or crank shaft.

Install crank pulley without forcing it.

Easy

PS: you should use some grease

 

o shoot just found out thats not the oem size, thats for underdrive, whats the difference? should it come with a bolt? or just the pulley and belt?
