Wiper upgrade on 2-litre cars

The problem with existing systems is often the poor state of the rack and wheel boxes as well as a tired motor.  Modern wiper systems for kit cars are readily available and transform the original system on the 2-litre cars.  Stick with the existing wipers or, if you are serious, fit a modern system. 
Such a system comes from Stafford Vehicle Components.  It can be adapted to use modified original wheel boxes so no changes to the holes in the scuttle.  A fair amount of fettling required.  It’s not a direct swap.  Once set up it is superb.
Holden’s and J&L Spares who recondition wiper motors may offer alternative approaches.

On the other hand, just disassembling, degreasing and re-greasing the various parts of the Lucas system will often speed things up and make the mechanism more vigorous.  Motors also often need their commutators polished and the grooves between commutator segments deepened so the brushes make good contact with the brass segments.  Relubrication of the motor bearings almost always helps speed them up.

406 Disk Brakes

Disc Brakes

One of the features of age is that I can remember many things from a long time ago – but not always accurately. My first memory of disc brakes was in the 50s as a young apprentice mechanic in the nearest Morris/MG Distributor to Fort Dunlop in Birmingham. Their development department used us as a fitting service for their test cars. In particular they had an MGA 1600 to which I fitted more sets of hydraulic cylinders than I care to remember as they attempted to make the pull back mechanism work (they never did). I well remember the constant exasperation of the Dunlop engineers, their cynicism and their bad opinion of their own product.

Even though in recent years I have fitted Dunlop brakes to four Jaguar XKs and my own 406 my prejudice has stayed with me to this day and I have never felt comfortable with their performance or durability. Imagine my joy to discover that there is now an answer. Zeus Engineering now makes front calliper sets and rear cylinders to modern standards and high quality.

Their product fits with little complication and additional pipework plus adjustment shims and instructions are included. One small point is to be careful to centre the calliper over the disc; my car had significant variance side to side.

I have now bedded in the pads and find the brakes to be powerful and progressive in the manner of a modern car. Beyond that I no longer have the comments of disgruntled Dunlop engineers ringing in my ears.

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.

Pegasus parts news

COMMERCIAL NEWS

One of our members refurbishing his brakes on his 403 enquired whether Pegasus knows of a supplier of the banjo bolts that fit into the wheel cylinders and copper sealing washers to fit these bolts.

I gave him the following company:-

Stevson Motors
Unit 1, 2A Harrow Road
Selly Oak
Birmingham
B29 7DN

Contact: Derek

Tel: – 0121 472 1702

They can supply refurbished, lever arm shock absorbers, stainless braided flexible hoses of all kinds, brake fittings and thick wall rubber tubing as used on our 2 litre vacuum wiper systems.

Derek could not help with the banjo bolts but he recommended another company. They were able to supply them and he stated they stocked other Bristol bits.

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.

Mike Say

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.
