Brum wheel bearings

[charlie weeks]

Hello All

Have just joined so I’m flexing my curiosity ! I own a 1960 Brum which is now looking a bit down at heel and I wish to do a little restoration. Can anyone tell me the reference numbers and/or the dimensions of the front and rear wheel bearings on my bike.

Cheers

Charlie

Hi, Welcome! Birmingham Scotts are a challenge for figuring out bits and pieces , I found the most likely way is to measure the items you want to replace and find replacements or alternates as there are no parts lists as far as I know .

Hi Charlie, My little book on all things Brum reveals —-Rear wheel,2 inch OD,x 3/4 inch Bore x 11/16 inch wide. Hoffman (MS8 /V3) , FAG MS8,etc. Front wheel, 42mm x 15mm x 13mm wide. (SKF 6302). The reason for the mix of impierial and metric is the rear wheel is of Shipley design, the front is all Brum (Aerco Jig & tool). Mad!!!

Metric bearings at least are available with built-in rubber seals and well worth considering.

They are the same overall size as the regular bearings, come “sealed for life” with the correct quantity and type of grease – basically “fit and forget”.

The bearings are identified by a RS or 2RS suffix, (one or two seals), these should not be confused with shielded bearings which carry metal protective covers that do not completely seal the bearing.

I have had bearings of this type in a Moto Rumi for over 20 years with no hint of trouble.

You are a STAR. Please publish your book of info onto the club site. It can also be used for sketches, drawings, exploded diagrams etc. Velocette must have original drawings. Would they allow the club to have copies for info only ?

Many Thanks

Hi men, I used sealed metric bearings on my Brum front wheel (Steyr 6302 RS), worked perfectly for the 25 years that I owned
the bike. I have no notes on sealed (imperial) rear wheel bearings,so they may not be available, Velocette Motorcycles (Aerco Jig & Tool) are not usually inclined to be helpfull with inquires,about technical stuff,

A quick web search has produced a firm calling themselves “Simply Bearings” who claim to have in stock the 2″ O.D. rear wheel bearings with rubber seals that you require.

See https://simplybearings.co.uk/shop/p42035/MJ3/42RS+Imperial+Rubber+Sealed+Deep+Groove+Ball+Bearing+3/4x2x11/16+inch/product_info.html

I hasten to add that I have never had any dealings with this company so cannot offer any comment on their performance.

Hi Men,Good morning!. I used “Simply Bearings” a few weeks ago to buy two tiny (12mm x6mm bore)for my noisy flew fan on my C/h wall boiler.They arrived the next day for less than £5 including p&p! The quote from Boiler Man £200,”as you will need a new fan motor,and they only come complete with casing,fan etc plus VAT, blaa blaa!! I fitted the new bearings and serviced the boiler in less than two hours,Tidy!!
