    Sprocket bolts coming loose ...
    #1
    Default
    All six of my rear sprocket bolts are all loosing up. I cant put a nut on the back of them as no room between the carrier. They initially got a lot of CV grease in them and did the best I could to clean it up (q-tips, engine degreaser) and switched to a real bolt with lock washer on other side and holding a little better. Using red lockite too (tried both liquid and gel) but suspect with any trace amount of CV grease its not doing much. I have now put a double lock washer on one and hoping it holds even better(?) but wonder if anyone else has any ideas.

    Torque to spec. sequence & Safety wire the fasteners
    Also get rid of the lock washers if doing this.

    What are the sprocket bolts threaded into?

    Bolt goes through sprocket into about a 1/2in thick circular flange on the carrier. When you rotate the carrier to tighten the chain it moves the flange in like a diagonal direction so these bolts ends would hit the main carrier housing on back side when rotating so thus cant put a nut on the other side.

    The safty wire is a good idea but would have to track down bolts with holes in them or figure out how to do this ... maybe some sort of snap ring like bracket to fit over the bolt heads to hold them but thats a stretch. Wish the threads were reverse thread but still not sure if they would loosen due to vibration, etc. Tha tis part of the mystery ... dont really know why they are loosening so easy. Seems aligned very well. I might have some slight chain rubbing as very tight clearances but dont know if this explains it either.

    Wish I had a pic to show but cant do this for a few days ...

    If your not have to loosen except for sprocket replacement, clean, clean loctite, then a little spot weld to hold ea bolt in place.

    I believe McMaster Carr has them also.

    Make sure that they are 180KSI allen bolts like Unbrako or Halochrome........

    Safety wire will just keep them from falling out after they come loose.
