Do I really need to replace screws?
Hi guys
Do I really need to replace the screws on my rear wheel? My manual says i need to put new screws on my disc and belt pulley. Do I really?
Thanks

Want some cheese with that whine??
I did eventually replace my Pulley bolts with some Grade 8 hardware so I won't have to do that again. I haven't had to replace the disc bolts.
Those bolts are supposed to be replaced because after stretching during install they won't hold the torque the same if removed. That's the theory anyway. I don't remember seeing anywhere that those bolts are "prevailing torque" fasteners that require replacement.
Being a safety item, you can make your own decision on whether to replace them or not.

I just went through the same thing on my Limited.... replaced the rear disc. Manual says to use new screws, is pretty adamant about it. I mentioned it on HTT forum & everyone said just reuse them.
I had already bought & used new ones.

do a search on here and you will see many wheels ruined because of pulley bolts that fail, loosen and shear off after working the holes oblong and backing out. Harley says replace bolts for a good reason.

OP must have a Clymer manual. Doesn't know that there's a big difference between bolts and screws.

The op is correct, the application makes the part a screw, because it threads into the part and is not secured by a nut.
Often you will see bolts in catalogs, parts diagrams etc, and the description will say capscrew.
