Mud - I know you converted to chain, but for someone just doing a remove-replace on the stock pulley rotor, can I get the specs on what bolts to order? I am ok with buying a new socket or two if that multi-tooth driver system is better than the old hex head. I am fixing to re-lace my wheels and have the hubs coated while I am at it. I'd like to order the pulley bolts ahead of time. Thanks.

the fasteners on my sprocket use a 12 point socket.
you probably already have them.
as to the specs - parts book says part # 3873. 7/16 - 14 x 2 1/2.
if you go with ARP or other,
you want to consider the threaded length and the unthreaded
in relation to the sprocket thickness.

Like any critical fastener they will fail if you do not use the correct bolt installed properly, it is as simple as that.
Only reason mine failed was I trusted an Indy to know the proper bolts and instead he used bolts that were too short.
A NEW quality Grade 8 bolt at least 2-1/2" long and properly torqued with locktite will not have a problem. I have changed these things more times than I can remember and have had only the one failure.
All it takes is for 1 of these to be loose and it will cause strain on the others which in turn will fail. These are one of the few bolts you truly do need to actually use a torque wrench.

well its hard for me to get to an actual Harley Shop this week and really want to get my wheel back on ... do you all think if I went to a local FASTENAL getting grade 8 bolts would suffice ?

Both part numbers come up when using part number search on the new castle hd part look up. This might be something to consider.
