    Gear and brake pivot bolt

    Hi after reading about gear and brake pivot bolts nightmare I decided to change mine on my 13 plate with 29k miles, so last night I set to it and 30 minutes later I was done with no problems and 2 new shiny pivot bolts, however on inspection of old bolts (see picture)I noticed paint marks on them are these the original bolts.

    Possibly they are original. But that is not paint, but special glue for screws, so that the screws are not loosened by the vibrations and movements of the motorcycle.

    The Paint shown on the HEAD of the Bolt in your Photo,
    is not the compound ( "Special glue" ) that digital has mentioned.

    The THREADS of the bolt have a variety of "Loctite" thread locking compound
    applied to them, to help prevent them working loose inadvertently.

    The Paint on the Head of the bolt is likely to be from when the Bike was assembled,
    and the bolt was torqued down to the correct figure. 

    It is common practice for Bolts that should be tightened to a specific torque, to be marked
    in some manner by the worker at teh assembky factory, to show they have done it,
    and to make it easier to spot any that have been missed when the bike is inspected.

    Cheers  :821:

    I think youíre right coconut the new bolts I put on had blue stuff on threads I take it was lock tight compound,Iím just surprised that original bolts lasted so long and no trouble coming off when you read some of the nightmares folk have replacing bolts.
    Many thanks  :821:

    The issue seems to be corrosion, or the bike having been on it's side and weakened the bolt right at the junction of the pivot and the shank of the threaded bolt.  It is definitely subject to compromise and the easiest and best solution is to drill the hex opening out to use a higher strength through bolt in the pivot and problem solved.  There are several different methods, I used metric socket head cap screws trimmed to the right length, flat washers, and lock washers, with NO Loctite, and it still uses the same wrench as a lot of the other fasteners on the bike.

    Recently replaced my pivot bolts and both of the new bolts had some type of blue loctite already applied.  :164:

    Mine did too. I removed it and applied grease instead.  I'd rather the bolts worked loose (unlikely, and it hasn't after many thousands of miles) than snap.  Is now an annual job to remove, examine, relubricate.
