Main Bearings?

how many different types of main bearings do they do for the rover v8?

the first set i got hadnt got any thrust bearings on the the centre bearing and the second set i have got had thrust bearings on the centre but top and bottom

my engine just has the 1 half (block side) that has thrusts on and the number 3 cap has the same bearings as the other 4

i thought the lower half of the thrust might fit but it wont as the tang is off set on it and the main bearing cap is central

im going to go back tomorrow but thought you guys might lead me in the right direction

Thanks
Si

What is the engine number of your block? That might help someone to answer your Q.

Is the main cap in question machined to take a thrust washer?

The centre main bearing is the thrust bearing. It's only the block-half of the bearing that has the thrust faces on it on later (large journal) engines. I'm not sure about earlier engines.

But at least one of the shells on the centre bearing must have thrust faces!

they think they should have the correct ones tomorrow

the origanal ones i got were to engine number and were nothing like right didnt even have thrusts at all

guy at 4+ said it was quite common that parts ordered to engine number didnt fit they were genuine Landrover ones too lol
