Bearing conversions - Tony Betts - 17-06-2019
hi all.
i could do with knowing what RHP BEARING NUMBERS. are converted to SKF BEARING NUMBERS.
It's excellent having all the RHP bearing numbers in the back of the Red Cross book.
But has anyone done the equivalent numbers for SKF.
If not I don't mind putting what I know forward, if others want to add to them.
I'm not good at the Internet thinggy of collating them.
It could benefit everyone.
Thanks Tony.

Off the cuff a rear main is CRM10A I think.
I think I have an SKF equivalents list at home, will take a look later.
RE: Bearing conversions - Tony Betts - 17-06-2019
Thanks chris.
Would apreciate it.
Tony.

Hmm, the list's not as helpful as I'd hoped Tony, I got it off Skefco 20 or 25 years ago...
But for what it's worth the following are old SKF numbers equivalent to the Austin part numbers in brackets.
I'm not sure all of these are available today but possibly others can fill in the modern equivalents.
Front Wheels Inner (2 K 5507) RLS 10
Front Wheels Outer (2 K 5506) RLS 6
Steering Worm (1 A 6131 - 1937-8) -
(2 G 5286) 7/32" Balls
Crank Shaft (2 K 7539) 400648
(2 K 5526) 402318
Cam Shaft (1 A 2 = 1934-37) W-6351
Propellor Shaft (2 K 5508) RLS 7
Bevel Pinion, Front (SR A/C Pair, 2 K 7543, to chassis 286570) 401216
(2 K 5505) RMS 8
Bevel Pinion, Rear (Cyl Roller, 2 K 5530, to chassis 286570 - 1937-8) CRL 9
Bevel Pinion, Front (DR Angular Contact, 2 K 5536, from chassis 286571) 3305 B
Bevel Pinion, Rear (Cyl Roller, 2K5585, from chassis 286571) CRM 9
Differential Right & Left (2 K 6538, to chassis 286570) ALS 10 or ALS10A
Differential (SR Radial, 2 K 5708, from chassis 286571) RLS 11
Rear Wheels (2 K 5507, to chassis 286570) RLS 10
Rear Hubs (SR Radial, 2 K 5678, from chassis 286571) 6207
Constant Mesh Pinion (SR Radial with Groove, 2H1317, 2 H 1049) 6207N or 6207 NR
Mainshaft Rear (SR Radial with Groove, 2H1318) RMS 8 N
And yes, if you can find one, CRM10A does nicely for the rear main crankshaft bearing.

Many thanks chris,
That covers most of what I need.
I might even be able to add a couple.
I bought a big pile of new old stock bearings last week.
There were 4 CMR10A and 7 RHP rear mains in the box.
If anyone want any a. Bit cheaper than normal. That could be the bargain of the weekend at 750.
Well now ive been informed it actually on.
STILL NOT SEEN ANY ADVERTISING THOUGH
Tony.
