oil level in the De Dion

    Is there anyway how to check the oil level in the De Dion tube?

    As far as i know there isn't. The plug is there to add some oil for lubrication, but doesn't serve as a level gauge. Also the correct amount should be mentioned somewhere, but this is usefull only if you are dismantling the tube and filling it up from empty.
    At the end of the day, the exact amount is not that critical, you just need to be sure that you have some oil in there so that the tube doesn't run dry.

    1/3rd of a pint.

    That's from empty. Quite how your supposed to know what's in there already I have no idea. If the boot's split, probably nothing, and if so 1/3pt as a starting point once the boot is replaced isn't going to do any harm, then a few shots every service.

    That is where my question is originating from. I recently overhauled the De Dion after having removed all the rear suspension and final drive mainly to replace the drive shaft oil seals in the final drive. One oil seal had started to leak and was dribbling down the brake disk. I replaced all the oils seals in the De Dion and refilled with the amount required (1/3 of a pint as Colnerov pointed out in the next rely). I haven't had any leaks to date but was wondering if there was enough oil. I shall assume there is.

    Later DeDion tubes were greased for life, with felt seals. I have experienced in the past, the oil migrating out past the new seal into the boot, which then degrades. So when I replaced that one on my white Rover in Australia, I put new seals in. I found the inner tube to be somewhat pitted, which explains the oil leaking, and then greased the bronze bushings and reassembled. Five years later the boot is still good, the grease seems to have stayed where it should be, despite not having the later felt seals, rather the earlier oil quad seals.

    Then replacing the boot last night on my Rover 2000 TC, in America, I spotted the jar of Castrol rubber grease. I thought that would be the perfect way to grease it, and if a little grease migrates out onto the rubber boot, it will not matter at all as it is rubber compatible. I thought that the rubber grease did not feel quite as slippery as petroleum grease, but I think it should work okay. I will see if it makes any difference to the way the car rides in the spring time.

    Has anyone else tried this?
