    Change final drive oil

    This is a VERY simple feat indeed!  Triumph says to change it at 500 mile service then leave it forever.  I can't do that.  I did it at my 10k service.  Oil very clean and only a little metal on the magnetic drain plug.  I plan to do it every 20k I think because it is so cheap and easy.

    1-  Bike on center stand, small block approx 1" thick under front wheel to level bike.

    2-  Gather supplies:

    *  New synthetic gear oil in 75/90
    *  Drain pan and rag
    *  5mm hex wrench or socket

    3-  Remove left saddlebag (pannier for you across the pond).

    4- Place drain pan under final drive.  I prop it on the wheel to make sure I get the drips.  My finger is on my socket stuck in the fill plug.  Drain plug can be seen hanging there over the orange drain pan on the bottom of the final drive.



    5-  Remove FILL plug.  ALWAYS remove fill plug first!  You never want to be in that situation where you can drain the fluid and are unable to refill it.



    6-  Remove drain plug and let it drain.  There is very little in there.  Wipe off drain plug.  It is magnetic so there will probably be a little fine metal shavings on it.  Wipe them off.

    7-  Replace drain plug.  Tighten to 18 ft/lb (25nm).  Stick the snout of your gear oil bottle in the fill hole and squeeze in oil until it is level with the bottom of the fill hole.  A little will run out of course.  I forget now, but it holds 3-4 ounces is all.



    8-  Replace fill plug also so 18 ft/lb (25nm).  Wipe up any mess and you're done.  Be careful not to get any oil on the rear rotor.  The pic with the fill plug removed also shows the properly filled level.  You can see the oil in there is even with the bottom of the fill hole and a little has run out.

    Easy-peasy.

    Well done, but what are these ounces you talk about  :156:

    converts to 85 - 115 ml, in real money. :047:

    For the UK riders, I bought - 1L Fully Synthetic 75w90 Gear Differential Oil 1 Litre GL-4 GL-5 - from Westway oils on ebay for 8.99.

    Forget everyone else likes metrics. :)  At least I called it a pannier. Ha ha!

    I think I got that bottle for about $11 at Walmart. Changing it every two years that bottle will last a while.

    Did you/do you need to replace the washers on the drain and fill plugs?

    Just curious....haven't read the factory maintenance on this bit, but I know in many other oil change applications (including engine oil on the Trophy), they replace sealing washers.


    Cheers,

    That's something that should be done at every oil change, be it engine oil or transmission oil!
    An old biker must be a good rider

    No combustion gasses, no other contamination except maybe condensation. Triumph says never after the 500 service. I am thinking every 20k is way more than enough.

    The recommendation is to change either drain plug washer
    every time the drain plug is removed.

    The parts are comparatively inexpensive :

    Sump Drain Plug : T3558989 ( 14.4 x 23 x 3 ) = 1.97 each
    Final Drive Unit Drain ( and Filler ) Plug : T3551272  ( 14.5 x 20 x 1.4 ) = 2.10 each

    Of course you CAN get away with re-using them, even many times,
    but the risk is that if they start to leak and won't "nip up"
    then you're left with the hassle, time, and cost
    of draining all that nice new oil out again,
    fixing the leak with a new washer, replacing the oil,
    and cleaning up the mess from where it leaked onto !
