Default Re: Fan Removal -- 2 Blade

Easiest way to remove 2-blade fan is to put fan horizontal,remove WP nuts & roll pump up & out. sometimes you need to tilt rad till it meets HL bar.Stone guards make it a bit more difficult unless you remove the upper bar bolts & loosen the lower ones.The fake studs do make it easier to re & re pump but its never neccesary to remove rad.To remove fan blade,I use the deep nut off the king pin lock bolt.Either put a couple washers in the nut or grind it a bit shorter & tighten it down making sure there is a bit of space between nut & hub.Keep nut tight between hits to protect threads.A couple hits should do it.When installing an aluminum fan always use a thin hardened steel washer or the nut will wear into the softer metal & blade will become loose.Also make sure the woodruff key doesnt roll out of place when installing.
