    2.7 TDV6 D3/4 timing belt service parts shopping list

    Anyone able to confirm the parts required for doing the 7 year/168,000km timing belt replacement on the 2.7L TDV6 engine found in the D3 and early D4's?

    So far on the list:

    LR016655 front timing belt kit which looks to include a replacement tensioner pulley and bolt.

    LR019115 rear timing belt kit for fuel injection system with tensioner pulley and bolt. I think there is a different part number for earlier pre-2009 or 2007 vehicles?

    LR076782 Oil pump with included gasket - as there was a period of faulty units without the webbing reinforcement that would fail where the timing belt tension mounted. Looks like this is the most up to date part number that has superseded earlier versions.

    Is a replacement front crankshaft oil seal (1102415) needed as well or does the front crank seal come prefitted into the new replacement oil pump?

    What about replacement camshaft oil seals (1311318) when changing the timing belt? Worth replacing these while already in there or best to leave undisturbed if they're not leaking? Are four required as it's a dual overhead camshaft V configuration engine?

    Should the water pump (LR009324) be replaced while in there or is that fairly accessible any time?

    According to Roverworks < Discovery 3/4 Range Rover Sport TDV6 Timing Belt > the plastic water coolant neck in the valley and idler pulleys should be replaced too, which are:
    1311306 timing belt idler pulley - 2x required.
    and LR073372 I think for the plastic water outlet - anyone able to please confirm?

    If you have a 2012 2.7 you do not need to do the oil pump etc as a matter of course, unless you suspect there is an issue.

    For other parts buy what you can from Ford as they are about 1/3 the price of LR for the exact same parts. I am sure many LR sellers buy the oil pumps from Ford at the Ford Trade price and sell at a LR retail price.

    Oil pump has been mentioned is worth replacing in any case all models due to maintaining oil pressure levels and minimising crank failure ( one theory). Believe comes with new seal.

    Yes - water pump - cheap and easy access.

    Also replace plastic coolant pipe junction piece top of valley at this time. Is a known failure point. Is also a plastic elbow on the block less talked about but hard to access.

    What I never hear about is the front accessory belt. When do you change that and tensioner?

    Noted, but I still plan to.

    Cheers. I’ll get quotes on the parts from the two local Ford dealers too then.
    I believe the genuine Ford part number for the oil pump is 4R8Z6600A.
    There's some big price variation on the Land Rover unit (LR076782) from Britpart at GBP 54.99, OEM at GBP 158.33 to genuine Land Rover at GBP 210.00. Looks like genuine Ford units can be purchased for cheaper as Jefferson Ford are advertising the genuine Ford 4R8Z6600A unit < Genuine Ford Oil Engine Pump Assembly For Territory Sz/Sz Mkii | eBay > for AUD $179.78. My two local dealers will hopefully be even better.
    On a side note, the second of the two pictures on < LR076782 OEM FoMoCo Oil Pump 2.7& 3.0TDV6 C2Z31680 LR123716 > shows where to apply the sealant in 3mm diameter when installing. Also mentions "...it also no longer requires dowels that were fitted at the base.".

    Out of interest I also found the following part numbers in the Dayco and Gates catalogues - both brands that I’d be happy to use, but especially Dayco as it seems to be the OEM supplier.

    Dayco:
    6PK1975 belt multi
    DP736 water pump
    KTBA288 - front timing belt kit that includes the belt, tensioner (but doesn’t list the new bolt being included like the Land Rover kits, so may needed Land Rover part LR006027 too as I assume that there is a reason Land Rover include it to replace, not worth the risk not doing to save $2.00 only), the two idler pulleys and KS135 seal kit consisting of four seals (both of which that the Land Rover kit doesn’t include).
    KTBA290 - rear timing kit which includes the belt, tension and a KS143 seal kit consisting of 1 seal.
    then there KTBA278 which includes all of the above items for both the front and rear timing belt kits less KS143 seal kit for the rear timing belt.

    Gates:
    6PK1975 accessories belt
    TCK1616A front only kit which includes belt, idler pulleys, tensioner and bolt. No seals included.
    Or TCK1616B front and rear kit which adds the rear belt and tensioner pulley
    GOSK1616 for the front timing belt oil seals.

    Do you have any more details on this? Part number or pictures of where it is and how to do it? Does the timing belt etc need to be removed in order to access this or can it be done at any time?

    Fairly easy item to replace at any time, so no significant benefits in cost or time saving by needing to do it with the timing belt. Fairly low risk if it fails - would be inconvenient as can no longer drive but is an easy roadside repair. Given the cheap price and that I assume it needs to be removed out of the way in order to do the timing belt I’ll replace it then regardless.


    What special tools are required?
    gates list GAT4965 Timing Tool Kit being recommended when the Ford kits are looked up.
    some of the UK sites list parts Britpart DA1120 Island 4X4 QP1924100 Laser 4273 or YF62233.
    According to
    Timing Belt Tools for Ford Territory Diesel 2.7L V6 SZ 2011 to 2017 Flywheel Pin | eBay the tool required for the Ford Territory and Land Rover applications differ as “...
    the Ford Territory which requires a larger Flexplate Tool.”

    That's the LR073372 I mentioned in my first post. I have no personal experience on it's location but assumed it to be at the front of the engine. The thread you've linked above also indicates this as the author is surprised that it didn't leak down the front and believed that to be due to the angle of the V engine configuration's valley or angle of the engine mounted in the vehicle.

    Unless you have very high mileage replacing the pump is not needed.

    To which pump do you refer? Water/coolant or engine oil?

    According to discussion on Disco3 forum < DISCO3.CO.UK - View topic - 2.7 TDV6 - replacement oil pump - front crankshaft oil seal >, new front crankshaft oil seal doesn't come with the new oil pump as it needs to be fitted after the pump is fitted. In addition:

    Quote Originally Posted by aja4x4
    There is a tool for making sure the seal is fitted correctly but most people use a socket. The seal has to sit 1mm back from the casing and if it's the new ptfe type needs to be left for 4hours before turning the engine.
    It's also been suggested that a replacement front crankshaft nose bolt is needed as it's a Torque To Yield type. This should be part number LR013377. Shown as 6A345 in the parts diagram.




    I'm also unsure about the 2x 1346539 oil seals? Listed in the parts diagram as 7G281.




    In regards to the other oil seals, their guidance is not to replace any unless they're leaking as you don't really go near them ref < DISCO3.CO.UK - View topic - 2.7 TDV6 timing belt change - any oil seals to replace? >.


    And I haven't found any other plastic outlets for replacing at the same time. Of note is that according to < https://www.disco3.co.uk/forum/27-td...be-185065.html > “...Landrover don't supply the o ring that fits it to the fuel cooler, (only a complete cooler!). You can get the o ring from Citroen/Peugeot, part number 198171”.
    According to <
    https://spareto.com/oe/198171 > that Citroen/Peugeot part number is interchangeable with Bosch 1 280 210 761.
    And according to < https://www.amazon.co.uk/Bosch-12802.../dp/B004YZRMJE > ASIN B004YZRMJE.
    Its listed as an injector o-ring seal part. According to <
    https://www.ebay.com/itm/Bosch-Fuel-...75.c1#viTabs_0 > they’re 18.55mm x 3.5mm - an odd size so not sure if the local bearing shop would be able to match it up. Come in packs of four if the Bosch variant is bought.
