    Default Td5 Oil pump life span?

    Sorry for my TD5 season. Its summer now in Norway I cant work in winter time in 1 m snow and -15
    Therefore advice and opinions appreciated.

    Whats the lifespan of the original pump?
    Do you advise i inspect mine? 244000km now
    Symptoms related to faulty pump
    Is the pump mechanical and all metal or can it be serviced?

    Mine is on 360k and (without a mechanical test of it's delivery,) all seems good.

    As to symptoms of faults, I guess about the only one would be the low pressure light coming on, unless you plumb in a separate gauge that reads actual pressure.

    It is mechanical, I don't know if it's worth servicing, if it's worn a new one will likely be cheaper. I don't even think internal parts are available.
    The major issue with them is the bolt holding the chain wheel on is known to unscrew itself with suitably catastrophic problems when the pump stops working.
    Cheers,

    if its all metal and mechanical (no gaskets and with oil film bearings ) and the bolt doesn’t unscrew then it should in other words last as long as it has serviced oil?

    maybe someone has an exploded view of the pump?

    For all intents and purposes, yes.

    Here is a thread where a guy opened one up, but it isn't particularly detailed.

    No. All pumps wear. I'd replace at 200,000kms.

    Shortly after I purchased my Td5 in 2004 (it is a 1999 model) I got the local Indie to drop the sump, remove the oil pump bolt and refit with loctite. Turns out it was tight anyway, but I wasn't taking a chance.

    Is this sprocket bolt given to fail at some time?

    No, as posted earlier, some early models were not fitted with loctite at the factory during assembly.

    I think the issues were mainly in the early 1999 models, but I stand to be corrected. Jelo?

    I thought they changed the design of the pump with the face lift in late 2002, or there about? I speak under correction.

    I'm pretty sure that all those that were going to fail would have done so by now.

    sorry, not a TD5 guru, I do remember the pump bolt issue though and it would have manifested by now

    Just replace the pump. Do the water pump while you are busy.

    Any pump dies eventually, we had to replace the Jeep JK's oil pump last month as the oil pressure was sub-optimal.

    There is a procedure in Rave to check the tolerances on the oil pump. They are expensive to replace but cheaper than overhauling the engine.

    I think i will make an inspection upon my next oil shift, i also have Locktite 263 (red) at hand unless someone know about some specific threadlock for use in submeged oil.

    If the bolt unscrews the oil pump drive is lost and pressure is instantly zero. You MAY get lucky if you have a borescope to feed down the front cover to try and see if the screw is still secure, but my feeling is that your issue of low/dropping pressure is elsewhere.

    I'd start with the relief valve possibly sticking slightly open and bleeding flow off.
    Cheers,
    John

    Mine was checked at around 210,000kms and the oil pressure was slightly down. Replaced it with a new one as a precaution.

    Although the new one was a genuine LR part, we had to tap one of the bolt holes as the thread wasn't cut properly.

    As per the manual, 0.7 bar minimum, usually 1-1.2 at idle with auto box. The pressure release valve opens at around 4 bar.. I get 1.1 at idle and 2. 5+ at 2750 rpm.
