one thing that most folks overlook is that this is the PERFECT time to replace the $7 front crankshaft seal .... If you don't you will need to buy ANOTHER new bolt after you repeat the pulley installation process when you replace the crank seal. (don't oil the seal where the balancer slips through, this type of seal does NOT like that ... use a little spit on it if you want the balancer to slide in easy)

Hope that helps,
