Hello,

I have a 2008 Land Rover Discovery with the 2.7 litre version of the Ford 3.0 V6 you get in the 2018 onwards F150. I am currently rebuilding the car in Scotland.

I'm looking for main and big end bearings, but in Europe you can't get the OEM bearings (engine is used in Jaguar, Land Rovers and Citroens - no one lists the bearings). You can get after market bearings from KING or FAI. But the OEM bearings are available in different tolerances to give the ideal running clearances (and hence best oil pressure). The aftermarket bearing are not, so I am trying to obtain Ford bearings.

Looking on Ford USA parts web sites you can order the relevant bearings. Example:

Crankshaft/Pistons and Bearings - 2018 Ford F-150 (fordpartsgiant.com)

BUT I am not 100% sure that the bearing journal sizes are the same and I need to obtain the Ford sizing chart to be able to select the right 'color' (tolerance) bearing.

I know that in Europe the 2.7 liter & 3.0 Liter have/had the same journal diameters, the only difference is that at some point the main bearings gained an anti rotation tab - you can machine in a slot in the main bearing caps to accommodate this in the earlier engine.

Request/Questions:
  1. Do you know the main and big end bearing journal diameters on the 3.0 V6 Lion as fitted to the F150?
  2. Do you know of a source for the bearing sizing chart (color codes) or the engine workshop manual?
I'd appreciate any help you can offer.

Adrian

P.s. If you are interested my rebuild can be seen on this forum:

Hi,

The 3.0 in your F-150's has the same bearing sizes as the European 2.7 and 3.0 engines - I verified by buying some bearings to compare against. However the bearings have a bronze coloured coating that I think has a higher load rating from what I can find out.

Hope that's of use to some one

Adrian
