    eg: the kart applied the brakes (hence the lights) and the "cars" emergency braking system sees the lights and applied the brakes! and maybe kits the foam pad.

    Well the day finished off with a couple of road bikes for service.

    Just after doing a frame swap.

    the main time was spent finishing of a GT dirt bike rebuild.

    the frame had been sand blasted and painted and the headset cups and fork fitted and came with a few bits to be fitted.

    img0432a.jpg

    img0433t.jpg

    first job remove the tape from the threads.

    img0434z.jpg

    then chase the threads.

    img0435p.jpg

    remove the handle to allow the facing tool to be fitted.

    img0436y.jpg

    Fit the facing cutter.

    img0437h.jpg

    then face the BB faces.

    img0438i.jpg

    Not fully done

    img0440d.jpg

    Done

    img0441.jpg

    Other side

    img0442i.jpg

    remove tool and clean.

    img0443a.jpg

    more in a bit.

    So that was the BB faced and chased.

    now fitting.

    check the width for the right number of spacers.

    img0444dz.jpg

    insert cup by hand.

    img0445n.jpg

    and then tighten.

    img0446.jpg

    assemble cranks and fit.
    (no pic)
    next problem the rear disc.

    img0447m.jpg

    solution. move spacers to between calliper and adaptor as the disc was also catching on the calliper body.
    also chain tugs were fitted to help with aligning the wheel as it waqs being run "short" on the drop outs.

    img0449p.jpg

    Done.

    Today started of nice and easy.

    BB change and gear set up on a road bike with a Sram groupset.

    I like the double tap shifters.

    then came a Marin.

    A steel framed Marin with problems.

    I wont say what was wrong i will just put up the pics.

    Sorry have to go back to the rear mech

    img0463.jpg
    img0464j.jpg

    So the first thing was to see if the frame was savable.

    straightening the mech hanger.

    next post.

    so the hanger straightener is screwed in and the bend removed.

    img0460.jpg

    then it is make sure that it is correctly aligned by measuring around the rim.

    img0458v.jpg
    img0462b.jpg

    when it is all the same it is right.

    Ok the BB is shot so that need to come out.

    it had been in for years and i had already split the cup on the non drive side.

    img0471y.jpg

    img0468oo.jpg

    great tool that screws into the BB axle as well

    img0467cr.jpg

    and out it comes.

    img0469k.jpg

    Lovely.
    img0470f.jpg

    so how to get the cup out as you can not use a BB tool.

    next post.

    So how to remove a stuck BB cup.

    Insert a Hacksaw.

    img0472lk.jpg
    and make some cuts.

    img0473be.jpg
    img0474s.jpg

    and then knock the pieces of Pie out.

    img0475j.jpg

    then chase the threads out and clean the BB areaready for the new BB.

    I presume the ND cup was plastic, can't see you cutting a metal one.
    I've added a signature to prove it is still possible.

    Yes and do the same on any cup the alloy ones may need a few more cuts and a bit more force.

    But they tend to not fail as often.

    That BB tool looks awesome, one hell of a good length on it (oo-er!)

    The rear mech is about as gunked up as the ones I usually get to work on too, why oh why do folks let them get so bad :roll:

  • Really interesting posts. Thanks.
  • What affect will straightening the mech hanger have in terms of strength?

    Looked unrecoverable to me, cracking job.

    it varies. in the case this mech hole is slightly Oval now. One more big bend and it will be a failure, Note this was a steel frame.

    So Today.

    servicing servicing and deciding to do nothing to a road bike as it would be better to let it all wear out rather than changing the chain.

    But it will be getting new drivetrain in the spring.


    Today's build.

    well just the start as we needed to see what we had and what we needed.

    and as the BB will be external it started with a chase and face.

    img0476e.jpg
    img0478t.jpg

    then it was decided to face the disc mounts.

    Fit the tool axle.

    img0479.jpg

    fit the cutter and face.

    img0480.jpg

    will continue with this next week.

    Judy DH?

    Think they're Marzocchi DH3s if I'm not mistaken, from around 95-96ish, when I very first got into MTBs and 80/100mm was considered plush!

    have a cookie.

    Well today was full of surprises.

    As known the two bosses were going to be away visiting Shimano.

    But they did not tell me that a "practicant" (Student placement) was meant to start this week, Well I sent him home as there was nothing for him to do. They can sort him out on Wednesday.

    so a few services and made a start on sorting out the shelves. So much stuff that is scrap but might be useful.

    Need a "Yard sale"

    Not seen one of those Zocchis since 1998 when a shop had a pair on a bike!
  • nicklousenicklouse Posts: 50,675 Lives Here
    As there have been a few topics where people have broken chain whips or bent them.

    my brace.

    img0483s.jpg

    and for really stubborn ones.

    img0482ps.jpg

    Oh and there is also a Park combo big spanner/chain whip.

    I'd have asked the student to sort out the shelves.
