    Can anybody help – maybe this is one for Julian and the chaps at LMB racing.
    A friends 16/80’s pre-select gearbox has no spring tension when the pedal is depressed and as a result the gears do not select or engage.
    Is it just a case of adjusting the spring tension nut (how do you get at it?), or is there other possible causes?
    Advice and help needed here please as the 16/80 in question has to make it to the AGM this year.
    Best regards

    Hi Chris,
    Sounds like the spring has either snapped or he has selected two gears at once which sometimes gives the same feeling.

    There is a big triangular plate on the rear top of the gearbox. Remove this plate WITH CAUTION as it is very heavily spring loaded as usual and can easily fly off and hit you hard!! the main spring is under this and you can check it’s condition.
    Let me know the outcome.

    Thanks Julian and Ray,
    The gearbox cleared itself after the engine gad run a little.
    I guess the vibrations released whatever had seized.
    Best regards
