Default Re: Model A Counterbalanced Crankshaft

AA Trucks were built at Fords giant plant at Dagenham east of London on the river Thames with its own dock . These were built into 1936 and many thousand built fitted with the fully conterweighted B engine . These cranks are still easily available here . They have been fitted to A blocks over the years some have all journals turned down but most have only the mains turned down the big ends remain B size . When this is done the oilpan has to be "dressed" in way of the big ends so they do not foul the pan skirt . This give a smoother engine and the smaller dia mains seem to hold up well with the added rotating weight Friend ran a town sedan with this done for many years . As an aside the oilpan with these engines had the AAE oilpan with no flywheel shroud so to mate up to the A flywheel housing .
