    Hello

    Just got back from Old Bar and noticed oil had been spitting out from the gearbox end of the gear shift linkage bit..the oil is coming from the rod that connects the gear box to the Shift coupler....

    I found the below diagram on line and where it has been labeled SEAL CARRIER AND BUSHING is where oil is leaking from... What is the oil seal / bushing for here called and how tricky is it to replace?

    Thanks Barry

    I was afraid it may be a full gear box removal job...

    Do you know if a new seal can be inserted as a temporary fix? just the seal not the bushings..

    My plan is to use Kombi all summer and then have a frustrating winter of motor out for more endless improvements !!

    Check gearbox breather hole is not blocked.
    Above hockey stick....centre top bolt holding nosecone on....there's a 3mm hole to the RHS ( of Kombi, front is front) of bolt .
    Poke something thru it to ensure its clear.

    Running hot with that blocked can pressurise box.

    Failing that...
    Not much leaks out but it does stuff the gear selector joiner material eventualy.

    Check gearbox level as 10 mm below side check hole or level.

    Havent checked but Should be able to pick seal out in situ once gearbox selector rear joiner removed.
    Tap new one in flush with a socket or similar.

    I've just rebuilt my three rib box and replaced bushes and seal, can purchase the seal on own
    ( Mick Motors P/No 001 301 227C)
    If you want to change the whole bush and seal also avail just a few sizes avail.

    Hope this helps
