    Wading Plug

    Found this little Item.
    Now I know why one bell housing stud was loner than others.
    Is it Put In to wade, Or Taken OUT.
    Thanks

    If its like the disco you put them IN to wade, im pretty sure ive read somewhere that its the same with the series gearbox.
    Must be for a breather or ventilation

    The hole is there to let out the oil that has leaked past the rear main seal. The wading plug is put in while wading to limit the ingress of water and mud. Leave the plug out for normal driving.

    Wow you learn something everyday. I didn't know about the wading plug until today.

    So I look under my Landy and no plug in the gearbox or in the bracket.

    Does anyone know the part number ? Is the wading plug possiblity the same as the swivel oil filler plug ?

    Thanks

    I wouldn't worry about it on anything other than a Series One which have a spiral on the gearbox input shaft instead of an oil seal to keep oil in the box . If you get water in the bell housing it would be sucked into the gearbox.

    The plug is a carryover on the S2 , 3 & 110 ect & IMO not needed at all, No other 4x4 has them It actually does not matter if the clutch gets wet so I never bother with them.

    If you want to use the wading plug, first make sure the grommet on the clutch cross shaft is in good condition.

    I agree with goingbush in general.

    The wading plug is not really needed and is potentially harmful. A bit of water won't hurt the clutch, but a bit of oil will, and if the plug is in you won't know the rear seal is leaking until the clutch is ruined.

    While water won't hurt the clutch, sandy water won't help it, and if you plan on prolonged wading or stopping in deep water, the water can get into the gearbox, which definitely will not like it. Remember the seals on the input shaft are oriented to keep oil in, not water out, and this applies to the output shafts of the transfer case as well, so after any deep wading, all oils should be checked for contamination and changed if necessary.

    I have never used a wading plug except on very rare occasions when planning deep water driving - but most of my deep water driving has been unplanned, and there have been no adverse issues due to water getting into the clutch housing.
