    I never liked the oilmist around the filler plug and the inspection plug of my rear drive. As we all know, the filler plug works as a vent as well and I never knew whether after heavy rain I got water in there or not without draining the oil. I already had the inspection plug weld shut when Bruno worked on my rear drive, and I had my local machinist have a looksee at the filler plug. We bounced off a couple of ideas how to best get a M10x1 thread in there in order to use a stock banjo bolt used on the brake master cylinder (a modification that I had seen somewhere else before). Well, the modification did not go as well as we thought, so Richard just fabricated a new plug, a stainless female-female adapter M18x1.5 / M10x1.0:

    Now, that worked out nicely and made a professional vent that leads under the seat. So no more oil mist outside or water in the final drive anymore:

    Hope that helps someone else as well.

    Just for the record, here's a similar device from Daniel Dicke's website. He used an adapter that was originally used to vent house radiators (!). Reportedly, these have the necessary thread M18x1.5, and you just need to cut the inner thread M10x1 - which in turn fits to standard hydraulic tubing.

    Joerg,

    Daniel's idea inspired me, but we hardly get any metric stuff here in Northamerica. Especially fittings or adpaters like that. The one "we-have-it-all" shop quoted me four (4) pieces of hardware to make up that adapter: metric-to-imperial-to-imperial-to-metric sort of thing.

    So we have to resort to other ways of getting there.

    walkingbear, nowhereman, I will talk to Rich, but I know from earlier cases that he is not interested in doing even smaller lots of say 5 or 10, he is the local "custom-design one-off" sort of shop!
