Re: Oil grooves mainshaft gearbox

I've checked out some parts lists and as is often the case the result still does not definitively answer the question...

The 1940 WD list and the 1940 'combined' WD and Civilian parts list shows the gearbox main shaft part number as 15-4260...

The WD lists for contract number S1048 (09-1942 to 11-1943)and S7218 (08-1944-1946) shows the number 66-3283...I don't have the list that covers the contract before S1048...

However, the post war parts list for side valve models (1949-55) and the parts list for OHV models (1949-52) both show the 'earlier' number 15-4260...

So, possibilities are...Both post war lists have an error showing the earlier number...Not all that likely I'd have thought...
The post war boxes reverted to the early pattern shaft...That seems illogical at first sight but maybe there was no gain in bush life from the modification that was made but the later shaft was more complicated/more costly to manufacture...Possible...In that case a reversion to the earlier pattern would be advantageous...Any other views on the subject..?...Ian
