Wheel bearings

Post  piston 197 on Tue Nov 28, 2017 3:36 pm

Rear wheels , not a problem standard metric size bearings cheap as chips ,about 4 each, get ones with 2RS after the number, these have rubber shields sealing in the grease.

Front cup and cones are a major problem and there is not a suitable bearing available to interchange, i have in the past machined out the hub to take a metric roller bearing ( nearest available size), but then you have to remake the spindle and nuts to suit a metric spindle !

There is no ready source of the front wheel bearings ( unless someone else knows different?)

Bad news i am afraid !

Hi Ernie, just read your post i had the same problem with my 1953 James Captain.I removed the bearing inner ball race then turned up a couple of sleeves, make sure the OD is a interference fit also the ID to take the bearing. I also used loctit on the outer sleeve. I fitted 6202 sealed bearings. The wheel spindle is the later type from VALE-ONSLOW 01217722062, did this 4 years ago no problems works a treat, good luck hope this helps Den.

Sounds good !

Post  piston 197 on Wed Dec 06, 2017 5:54 pm

Sounds good , but the bearings in the Plover /Kestrel/Cadet 4" hubs are smaller than in the Captain 5" hubs , also so is the spindle, and the later type spindle is a lot bigger diameter and much longer and will not fit the earlier forks used in the earlier150cc machines
FB/James did exactly as you did for the trials models and later roadbikes like the Falcon 67 which were fitted with the roller bearings, but it is a much harder prospect in the 150cc machines , you need to bore out the wheel to take the nearest size metric bearing, then make a new metric spindle with built in spacer and new wheel nuts.
I know i have done as you did with the bigger hub bikes, but it is a very different prospect in the smaller hubs !

Hi JOHN, I did not know they were 4 inch hubs learn something everyday I thought they were the same size as the James. Never mind probably help someone with 5 inch hubs. Den.

Wheel hubs

Post  piston 197 on Thu Dec 07, 2017 5:50 am

They are the same as the James Cadet, but not the Captain, these small hubs were used on the Cadet and plover from 1955 to 1960 and James Comet of the same period
