    Today set about another part of my plan to change the oil fluids on my FL2 i have already done the gearbox oil, & the rear diff oil.

    The next oil to be drained and changed was the PTU oil, i have used 75w/90 in the link below.
    https://www.ebay.co.uk/itm/5L-Fully...W-90-Gear-Oil-5-Litres-GL-4-GL-5/121635277054

    As most of us know there is not a drain plug the PTU as it is supposed to be sealed for life o_O therefore i decided to use a suction pump, which worked well changing the rear diff oil over.

    Some owners have used one of the lower bolts on the PTU which they removed and drilled a 3mm hole to break through the case, i did not fancy doing this so opted for the suction pump solution.

    As the FL2 was already on my four car ramps from doing the diff yesterday all i had to do was remove the under tray / guard.
    [​IMG]1

    To remove the engine guard you will need a 13mm six sided socket & ratchet, there are six bolts holding the under guard on back, middle and front either side.
    [​IMG]2

    [​IMG]3

    [​IMG]4

    Once you have removed the bolts lower the guard and put it safe away from the car, now you can see where the PTU filler plug is situated, you will need to look over the front sub frame to get a good view.
    [​IMG]5

    To undo the filler plug i used a long 13mm aviation ring spanner through the sub frame and the pipe, the aviation spanner gives you good leverage.
    [​IMG]6

    Once you have cracked the filler plug you can then reach over the sub frame and remove the plug & copper washer.
    [​IMG]7

    Check the filler plug to see if it as any sludge etc on the end of it, mine was fine no sludge.
    [​IMG]8

    Wipe it clean and add a new copper washer ready for re-fitting after the oil change.
    [​IMG]9

    Next i set up the suction pump under the car, the small 5mm tube need to enter the PTU at about 17.50 on a clock face, move it about a little until you can feel it go into the PTU slowly push the tube further in, it is quite tight.

    I started the pump to drain out the oil.
    [​IMG]10

    Hopefully you can the entry and angle of the tube into the PTU from these photos.
    [​IMG]11

    It took at least an hour to drain out 500ml which is all i could get out due to the tightness and angle of the tube in the PTU.
    [​IMG]12

    To make double sure and to see the true colour of the oil i poured it into a measuring jug, as you can see the oil is dark brown not black, which some owners have declared.
    [​IMG]13

    The measuring jug also gave me a better reading as to how much came out which was about 575ml
    [​IMG]14

    Here is the small pot of the new 75w/90 next to the used oil removed.
    [​IMG]15

    Now i turned my attention to getting the oil pumped back into the PTU once again not easy because of the angle of the filler hole and access, i used this below.
    https://www.ebay.co.uk/itm/Draper-T...415977&hash=item48bc115e31:g:PWEAAOSwl5JcHTtt

    This was great on the rear diff so no reason why it should not be good on the PTU.
    [​IMG]16

    I pumped in 700ml
    [​IMG]17

    Which then the oil started to run out of the filler hole, which i let run until it stopped
    [​IMG]18

    I then sucked out 60ml with a syringe and 3ml tube and refitted the filler plug with a new washer, cleaning up the area with carb cleaner.
    [​IMG]19

    I then stuck a magnet to the oil filler plug on the out side until spring, when i intend to drain off the oil again and replace with new, this time i may go for adding a drain plug in the area at the lowest part of the PTU, which i have shown here in this photo.

    The bolt with the arrow is the one some owners have removed and drilled into the PTU with a small 3/4ml drill in the centre and then used this as a drain plug, but as you can see it is not the lowest point.
    [​IMG]20

    The circle with the X is it seems to me to be the best place for a drain plug to be fitted.
    [​IMG]21

    I hope this helps others tomorrow i move on to the Haldex filter change and oil.

    Nice write up Arctic2, did your syringes and 3mm tube come from the bay also?

    Hi Neil
    Yes i used this to drain out the oil from gearbox, PTU, rear Diff, and Haldex.
    https://www.ebay.co.uk/itm/Electric...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

    Tube which i purchased 4mm 6mm 8mm as tubing is always useful.
    https://www.ebay.co.uk/itm/8mm-PVC-...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

    syringes i purchased from here.

    Thanks Arctic2, I feel an eBay spending spree coming on come payday.


    My pleasure guys & gals, i have also took a few photo of the Haldex oil change using the same suction pump, and syringe etc which i will post up sometime this week, over period of 4 days knowing the weather was going to be fairly good to us i did the Manual gearbox oil, PTU oil, rear diff oil, & the Haldex oil, having done the engine oil a month or so before.

    I tried to do my PTU oil yesterday, but couldn't get the plug out, not even with my impact wrench.
    I might leave it till next year now, although I do need to do the Haldex fluid, as it's dragging slightly, even when the vehicle is off.

    Hi John.
    Is it rounding off? if so maybe an Irwins bolt grip will sort it out.

    No Arctic. The bolt head is fine, it's just bloody tight.
    Because it's in an awkward place and I didn't give myself enough room, I used 2 extensions on the socket, which does affect the effectiveness of an impact wrench. :(

    Next time I'll lift it higher, so I can get the impact wrench straight on the socket.

    Do you know what thread size the plug is? so I can check I have the right size Dowty washers.
    Cheers.

    Hi Nodge
    I purchased these below M18 x 28mm x1.5mm
    Copper Sealing Washers Metric - M4 M6 M8 M10 M12 M14 M16 M20 Flat Seal Washer | eBay
    [​IMG]A

    I used an aviation spanner to undo the bolt.
    [​IMG]1

    [​IMG]2

    pump to get the oil out.
    [​IMG]3

    Pipe needs to go in at about 19.00 or 7 o'clock you will feel it find a little gap in the PTU which can then be slide in further.

    That's for that.
    Have you done your Haldex fluid yet?
    Mine is dragging slightly, so needs to be done ASAP.
