Thread: New Oil Pump

Especially since the price seems to have dropped markedly since even last year.

Hi Justin. So how do we great unwashed know whether we have old or new style oil pump please?
VIN based maybe (but LR don't have a good record in sticking to that principle) or??

This is the old oil pump - the one prone to failure

This is the newer oil pump.

Note there is no reinforcing around the top of the housing where the flat machined face is.

Notice on the bottom pic there is reinforcing between this face and the bolt holes.

I cannot remember the actual VIN range, however as a general rule any 2.7 manufactured up until end of 2008, is suspect. I believe all 2009 on were fitted with upgraded pump. I always quote on it for 2009 models, if you don't need it then don't fit it😊

Remember these guys were the first in space, so I believe they know a thing or two about engineering.

LR is popular in Russia too.

I guess everyone wants to be first to be second. One way to check their claim would be if anyone got some real-time diagnostic tool oil pressure readings at the 3 rpm points as mentioned on the Extra 19.5 pump site on a D4 with around 200,000kms and see what the pump is doing. If I had a code reader I would be checking (D4 SDV6 SE with 189960km...)

And yet they built the Lada so not all is engineered properly, can't find any reference to anyone that has fitted one .

Don't be so quick to blame the Engineers. The father of one of my school mates is a Mechanical Engineer (and he's done some awesome work since).

His first job after emigrating from NZ was to design the heater assembly for the new (at the time) Torana. He told me he designed an effective unit which was cheap to manufacture, met all the defined specifications and would for all intents and purposes last the life of the vehicle. He was instructed (in writing - he still has the letter) to re-design the heater core to ensure most of them lasted beyond the warranty period, but not much.

Even back then the bean counters had a good reign on the engineering.

Random questions never having examined this (got a new one fitted while something else was going on in there before I took over the maintenance myself).

How long is that bolt? If you over-torqued it could it stretch far enough to push on the block?

I is anything like the HPFP bolts then it’s made of unobtainium , 14’ long and done up to 10000Nm using an M8.5 whitworth spanner.
