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.

They did an excellent job and the cost was £250-300 for all three – not cheap but kit now like new.  They quoted 6-12 weeks for work to be done.

Ed.  Extract of services provided pasted below as taken from their website Oct 2013

Over the past 80 years or so there have been innumerable carburetter designs by many different manufacturers, and it would be impossible for us to compile a detailed rebuild procedure for each one. However, all carburetters tend to follow the same principles of design, enabling us to give an indication of the various processes involved.

  • Carburetters are completely stripped.
  • Components are subjected to a four part chemical cleaning process which is the only effective way to remove dirt and corrosion from the internal circuitry as well as restoring the castings to their original appearance.
  • Castings are polished to a high standard, or stove enamelled. *
  • Mating faces are re-machined to ensure flatness.
  • The throttle spindle housing is re-bushed using P.T.F.E. lined glacier type bushes and line reamed to correct tolerance.
  • Steel components are de-rusted and inhibited.
  • Steel components are re-plated. *
  • Brass components are chemically brightened.
  • Brass components are polished. *

* Denotes concours service only.

Carburetters are now re-assembled using all new wearing components, i.e.:

  • Throttle spindle
  • Float needle valve
  • Throttle plate
  • Volume/Air screw
  • Throttle plate screws
  • Diaphragms
  • Metering needle
  • Seals and washers
  • Jet Ancillaries
  • Gaskets

Any other components found to be faulty will be replaced. All internal components are adjusted and set as per manufacturer’s specification.  Carburetters are then engine tested to ensure correct functioning of the following:-

Fuel level, Idle circuit, Choke mechanism, By-pass circuit, Pull down and fast-idle operation, Progression circuit, Correct throttle operation, Main circuit, Correct response to mixture adjustment, Pump circuit.

(Upon re-fitting to vehicle, normal adjustments will be necessary)

Carburetters are given a final inspection and guaranteed for 12 months.
