404

I have acquired for the Bristol Hertitage Trust a rare 1950’s publication which contains an article describing in detail the design and manufacture of the 404, followed by a review of the car.

I would like to share the article with any forum member who may be interested.
To receive the scanned items as one .pdf attachment please email a request to me at bristol@davedale.co.uk / bristol at davedale dot co dot uk. On previous occasions I have had many requests to see items that I have scanned. Please be be patient and be prepared to wait for a reply as it is easier for me to do nothing until all requests have been received and then I can send out the scan to all, as one mass mailing.

Please don’t post your request to this forum. Many thanks.

Dave Dale.

Wheel Bearings

bearings

Manufacturers do not want to make replacement from other sources that easy, regularly mixing two standard bearings into one assembly, although I doubt that Bristols went this far.

Take off one complete set of bearings (2 sets of bearings per hub; the inner bearing is usually larger than the outer; both will be tapered roller bearings) and find yourself a local  machine tool service company.   Take your bearings in and they will measure them while you wait (about 5 minutes).  There are 3 grades of bearings used classed  A, B and C.  The tolerances in manufacture are, of course, extremely tight so they employ an automatic grading system – A being the best and that’s what you want.  C are the poorest and probably go into washing machines and the like.   I think the classification system may have changed possibly 1 – 3.  If the numbers on the bearings are visible you should be able to quote these to any bearing company and avoid the need to go to a machine tool service company.

Valid at time of writing in October 2016:

There are a number of good bearing suppliers eg Seager Bearings, Kings Heath, Birmingham (0121 444 5391) who will supply at trade prices.
