So last night I managed to bust a bolt, should have been paying more attention to the task at hand. Anyways, the part number is 3976 in the manual for my 2008 xl883. No shops in San Diego have it, but there is a hardware shop not far from me that has everything I could need, including chrome Grade A. The bolt hold the anti rotating plastics on the lifters. Guy at the Harley shop wouldn’t give me the thread or length. Spent some time on google, can’t find anything. Any help with finding the specifics of the bolt or a good website to use would be greatly appreciated!

 

not sure, but do you have the top half that you broke off..........take it to the hardware store and measure the thread pitch, they can do it for you

your gonna have to get the rest out.....now you got the length

 

Getting it out is taking some finesse at the moment. But once that’s done seems like it’ll be my Only option.

 

some1 might chime in on the answer, but you can do it.......yep, finesse is what it takes, and problem solved

keep us updated so others will know what size

 

Can you remove another one (that's not broken) and take that one to the hardware store to match up?

 

Put some pics up of which bolt you are talking about

 

If you search the HD SIP sight for your year and model, 2008 Sportster, you can find the online HD parts manual.
Use the search at the top right hand side.
