What do we see here?

<< < (4/11) > >>

Bryanj:
Not special just not the"normal" pitch for that diameter, still a standard metric though

deltarider:
Thanks for clearing that up, Bryan. If the thread of the clovis has been accidentally knackered by me, the LH side will have the same solution, I did RH side: a somewhat longer bolt and a nut on the other side. I believe there's room. Could be it implies temporarily removing the wheel, which is not that much work.
@ Ash Does not seem very off-centre. Camera lens has a will of its own, resulting in a personal view, I guess. ;)

AshimotoK0:
Functionally I don't suppose off centre is that bad anyway ... I am just trying to jig up some 250k crankcases to drill out a broken off an M6 screw ...trying to use a sleeve in the other half case with a tight fitting, long series drill to guide the drilling centrally.

Just M10 x 1.25 which seems to apply to most 10mm threads on the bike.

deltarider:
I'm sorry to revive this thread, but there are still a few things not clear to me. It's about the fastening of the rear shocks at the bottom. Let's look at these, what we call, breast bolts (10x32).
I can understand the clevis has a thread on one side, to save space.
What I don't understand is:
A) What is the breast part of the bolt for?
B) And if it is useful, why is the breast part not longer? The inside of the bushing is plain. Why would you need a thread there?
C) Another thing. In the pic we see the clevis and the bolt but no washers. Is a washer or spring washer not needed here?
I do not have a real problem, but I'm just curious what's the ratio behind it.
If you mount the rear shocks, is there a working order to observe? I mean to not damage the threads. In the past I must have done something wrong. On the RH side I have a longer and fully threaded bolt, with an extra 10mm nut against the outside of the clevis.
On the LH side, the bolt has the original length, but does not really fasten.
I must have done something wrong, but I can't remember it. Too long ago.
