Hi Ben,
There was a RM8 bearing specified in Carrier, the army stock number was MT7/28622. It is a double row ball bearing 1" x 2.5" x 0.75", the number is the same size as RMS8 which is a single row ball bearing which is easily available.

I also found a thread from 2011, here:

I cannot remember the part number. It is an imperial bearing, the bore size being 1.000" The Australians saw a bit of common sense and changed theirs to a metric 6305 (standard metric annular grooved) which is what the cam rollers and cam plate pivot bearing is. The metric 6305 is 62x25x19 so the imperial bearing has a bigger bore, and a smaller O.D.
Back to the imperial bearing, it is quite expensive, and hard to find, but as has been stated here, a few vendors in the U.K list them ( not around the rest of the planet) (RM8 = 2 1/2" x 1.0" x 3/4") If you can get a non self aligning bearing in the right size (I think the RM8 is just annular groove) It should work just fine. Phew!
BTW the self aligning bearing is supposed to have the lowest rolling resistance.

Thanks. The single row comes out at about £3 each the twin row self aligning about £25.

The British column has no bearing and as Lynn says the LP ones that came with the scout is a different size.

I like the carrier ben, it looks really good

Cheers Rick.

Bearings....... Checked today, SKF RM8 on the bottom of the column, SKF 6305 on the cam and rollers. The RM8 is missing so I'll need to get one, about £25..... The 6305 are much cheaper at about £4 each, the only change I'll make is to get sealed bearings for the cam and rollers. It'll save any dust or water getting in. The ones that came out are very rusty, fortunately the bolts and roller inners are gleaming.

What's the standard finish on the cam? Doesn't look to be painted, were they just well greased on the faces?

Ben, and anyone else, just the standard caution, check the cam plate bore and column dia. against what you are buying, before doing so.
I can't answer about the cam plate finish. Mine have always been too rusted to tell.
FYI. the only other bearings that are imperial sized in the carrier are those in the fan extension. (British style)

Ben, I just bought 3 of the RM8's from simplybearings.co.uk they also do the carrier wheel bearing 6408 at £20 each.

I think once you have cleaned up your cam, cover it with grease. Before you put your cam bearings in, pop one seal and add some more grease, (they never come with sufficient grease). Also don't put your radiator in yet !, consider tack welding your cam plate mounting plate left side retaining nuts to the carrier floor, that way later on if you have to drop the cam you can just unscrew the bolts out from the bottom (my plate is missing some left side bolts due to the sheer impossibility of fitting them with carrier engine/radiator/cooler assembled!).

Anyone got details pics of the cam plate canvas cover, not the drivers compartment rod cover but the rarely seen cam roller covers, I think Richard had a pic of this when he bought his carrier.

Ben, Also before you fit your cross tube, lay in your gear change connecting rod under it!!.

kev.
