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.

Useful information on the Lucas DR1 and DR3 wiper motors as installed on the 2-litre and Jaguar XK 140 cars is contained here.

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.

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.

Car Audio – New world tech, old world charm

The age old question for classic car owners is whether to fit a modern audio system that pleases the ear or a period radio that pleases the eye.  Stuart Risebrow has attempted to “have his cake and eat it” by fitting a modern audio system with period looks.

v8 parts-4

 

This unit, manufactured by “Retrosound”, a USA company, was found to be perfect for the job.  You have a range of period bezels and knobs to choose from that replicate the look of classic radios such as radio mobile and Phillips.  However,  the two rotating switches are detachable, allowing bespoke placement as well.

You will see that Stuart chose to make up a plywood insert to fit the mounting whole in the dash which he then veneered himself in walnut before adding a polished lacquer finish.

The “Retrosound” radio also comes with a small auxiliary unit that is wired to the rear of the radio and located remotely.  This allows you to plug in an SD memory card, USB storage device or 3.5mm audio jack.  The SD card allows you to store 1000’s of songs which is perfect for all those 60’s hits and Glen Miller tracks!  Stuart placed my remote unit just inside the glove box.  You would hardly know it was there.

The radio itself has an inbuilt amp that provides plenty of “oomph” and has all the expected outputs for larger amps, aux players or an electric ariel.

 

 

 

2 litre engine oil

Castrol Oil

Which engine oil is recommended the straight six Bristol engines?

Dave Dale and John Lawley both place great faith in Castrol Classic XL 20/50.

John Lawley, BODA technical officer, has more recently been using another oil also developed especially for classic cars. If you go to http://www.commaoil.co.uk/productsguide you will see 3 versions: a combined winter/summer oil, a dedicated winter oil and a dedicated summer oil. I use the combined version and have been very satisfied with it.

The only reason for the change is that my current motor factor does not stock the Castrol oil only obtaining it to order. However, they stock the Comma oil so I thought I would give it a try.
