I've been a very naughty boy today

  1. Well after a year off the road I have finally decided I should get on with this.

    First off was to purchase way too many gearboxes on the hope of getting enough parts to build a decent gearbox .

    Well we sort of managed it. (It become a bit of an obssession/problem buying so many boxes)

    @theBusmonkey , Neil, the master builder has carefully constructed what I hope to be a beast of a box suited to go with a scooby engine and extra special locking diff.

    So I will soon be collecting a rather nicely done gearbox, with extra oiling plates maim bearing retention plate, locking diff, rjes Subaru bellhousing, (other stuff I have already forgotten that Neil will hopefully fill in.)

    That looks to have a tasty specification, looking forward to seeing more!

    It's was a pleasure build actually. Matt's collection of eclectic parts allowed the use of a 2wd case that could be machined to take the vacuum actuated locking mechanism.
    Not every box can be adapted in this way, and the other cases provided what hopefully will turn out to be a really good set of standard VW gears.
    The bell housing was also a good buy. It required some repair and some assistance from Richard Jones, and between us he provided an oversize clutch bearing sleeve and I got the housing machined to fit.

    Full complement needle rollers on first gear.

    Locking differential, 4 pinion from syncro with pinion bearing oiling plate. These plates were first fitted by VW South Africa to improve oiling to the main bearing and the pinion bearing when they stuffed the 5 pot Audi into the T3. An obvious upgrade for any box with more power than standard.

    The main bearing retention plate. Helical gears force the shafts apart axially and over time the main bearing that supports the main shaft moves in the case. The same applies to our bay boxes and to help prevent this happening some machining occurs and the plate is fitted.
    This is only effective with a really good condition gear carrier, which fortunately Matt had in the stash.

    A mock up of the vacuum operated locking mechanism. A plunger pin moves a fork which in turn engages a castellated collar which locks the internals of the diff so both axles rotate at the same speed. This will have a boot fitted when it's offered into the doka to protect the pin and sleeve from muck

    And finally, a source of leaks on our own bays and also on the later T3's is where the seal on the side if the case eats into the CV output flanges.
    A nice repair sleeve from SKF gives more life to a stupidly expensive flange.

    Oh no, I've just provided the inspiration for him to get his backside into gear, if you'll pardon the pun!
    A 2wd doka with a locking diff will be quite a bit of fun :thumbsup:

  15. Build it up with weld give it a tickle with the die grinder and it will be as good as new

    I keep that one on the shelf directly in front of me, as a reminder that it's only a collection of bits of metal and that Marmite happens!

  18. That's the old race box outta the Bug, it had the Marmite kicked out of it doing starts on slicks, I suspect.

  19. Very rare panel found and purchased. Lost more less rare panels on their way.[​IMG][​IMG]
