the pot with the mounting lugs underneath were used on the first engines with detachable heads c1929 to 1931. It is therefore quite possible that your car has the appropriate holes in the side of the chassis to bolt them on to! Not sure about this but the longer studs could have been because of a di...

Not in the least Tony - a second opinion is always a good idea or perhaps sometimes the best out of three!

I have come across that sort of end float many times way back and as long as it is not knocking it may be ok particularly on a low annual mileage old car that is not driven hard. It is however well over prescribed limits of I think around 6 thou!

george

Tony/Barry I might have got the wrong end of the stick! I read it that John Box has 7 hp pots fitted with 8 hp pistons - hence +60 - rather than 8hp pots. If 8hp pots they will need modifying as Tony suggests so best check with John BOx as to exactly what they are.

george

Barry. a standard 8hp piston is roughly the same as a 7hp + 60 thou and should give you an extra 40cc capacity. However a note of caution the max rebore size recommended was +40 ..but I did run one with +60 many yeaars go. Those John has with skimmed heads may raise the compression ratio usefully - ...

I cant remember there being any shims or whatevers to control camshaft end float and no mention is made of any in the CA Bradford parts list. I don't think 23 thou end float is going to do any harm but would recommend that you follow Tony and fit a ''high lift'''' !! Bradford CA camshaft. It will do...

the chassis and engine look to me to be 138/9 van rather than Bradford. The engine has the late type ( fat) hydraulic mountings and no flanges for the Bradford rubber mountings. The chassis does look to have the correct mounting holes for the hydraulic mountings. It should also haave Bendix brakes a...

Have only just looked through this thread as tend to only look regularly at the pre war and Bradford bits. The one and only Jupiter I owned in the sixties came to me fitted with 2 downdraft SU carbs . The result was an extremely smooth engine that would manage 40 mpg on fast trips eg Manchester to B...

Post war 4 cylinder Jowetts enjoyed a degree of publicity that was out of all proportion to the size of the firm (? because of their enviable competition successes and the very advanced nature of the Javelin) As a result the relatively few crankshaft failures and the self inflicted gearbox problems ...

around 1960/61 one of the steering box mounting brackets on the crossmember broke off. I phoned Jowett Engineering at Howden Clough at 6.30 pm , not really expecting anybody to be there. ' The phone was answered and I aasked if they had a steering box cross member for a CC Bradford. The response was...

Tony / Andrew. I don't have any official references but would suggest a process of ''suck and see''. On the basis that a Bradford could carry 8 or 10 cwt officially aand up to 50 % more unoficialy! ( I have had 15cwt on board!) for a car with a light arse end the bottom two short leaves could well b...

It may work but will run the wiper motor too fast and probably overheat the motor. (6 volt starter motors are ok on 12 volt but they are much heftier) Simplest way would be to try to obtain a 12 v motor from a CC Bradford ( beware early CC's were 6 volt) Its a standard lucas motor common to other ve...

Barry, if you have to take the timing case cover off it is worthwhile drilling a small hole between the bottom of the timing case and the crankcase so any exess accumulation of oil in the timing case drains back into the sump. This 'mod' may of course have already been done to your engine.

george

if the pump body does not push into the crankcase by hand I would advise heating the crankcase until it can as this enables the pump body to be rotated slightly if necessary to line up the bolt holes. It also ensures a good tight fit on cooling. To ensure that the araldited bits are in line I would ...

the glued bits will not be under any great strain as they will effectively be clamped by the bottom plate. The usual reason for that type of breakage is cack handed attempts at removing the oil pump by force rather than aforementioned heating until it drops out.
