Need help identifying part numbers - screws
« on: October 13, 2019, 11:15:16 AM »
Hi,

I am trying to find BMW part numbers for couple of screws (marked 1 and 2).

I think #2 is 31422312035 (Fillister head screw) but I'd like to confirm before ordering.

#1 on BMW diagrams is refered to as 07129904984 (Torx bolt), but it looks nothing like Torx bolt.

Thanks!

Which source are you using to identify these parts. realoem, MaxBMW's fiche, Bob's BMW's or another? Please identify the year of your moto.

The lighting of your photo doesn't present a clear image of the screw's head.  It looks nothing like a Torx bolt is an incomplete description. What does it look like? Realize that in the course of production bolt head types can change.

Max BMW's fiche says they changed the head of that bolt from fillister to Torx in 8/91.

12    07 11 9 901 106    FILLISTER-HEAD SCREW - M10X50 (to 08/91)   0.09    2     $4.84ADD TO CART
    07119901106 was superseded by 07119904984.

12    07 12 9 904 984    TORX BOLT - M10X50-ZNS3 (to 08/91)   0.09    2     $4.84ADD TO CART

Consider not replacing with original for number one.  A bolt with a deeper recess could be better.

You have correctly understood Wolf's parts fiche. Your fork brace assembly matches their diagram and you've listed here the correct part number.

Is there a part number stamped on the slider? How long is the axle pinch bolt you are replacing?

Unfortunately my bolts were seized and heads were pretty much stripped/destroyed during the retrieval.
Bike is at the shop right now so I had to use this picture form the Internet.

That could be problematic because there are two differing fork brace assemblies. If you're certain that the photo you have posted is the same as what you have then my response stands.

Is the shop drilling out the stubs and tapping if necessary but you are going to replace parts then reassemble?

It looks very much like my fork assembly. I'll get to the shop next week and will take pics.
We managed to get the screws out properly both from the fork and the lower triple. Only the bolt heads didn't survive the process so I am just trying to get the new bolts.

Yeah I am trying to find an original one. Since mine is completely stripped now.

What we have here is a failure to communicate. :-)
