During that time we were working on the early Borg Warner automatic transmissions installed in the Cortina. The flex -plate drive for the automatic transmission required the bolts securing the flexplate to be removed to enable the transmission to be disconnected from the engine before the two could be separated. To access these bolts required that the sandwich plate have a removable piece at tthe bottom. The early, pre-automatic transmission 4-bolt flywheel Kent engines had a one piece sandwich plate, open at the top without a removable piece at the bottom, later 6-bolt flywheel Kent engines and all crossflow engines had the sandwich plate with the removable section.
That has answered a question I have had for 40 years!!!
Now why does the plate have a split in the top section?
Is it so it can be removed without removing the flywheel or more likely that it can be fitted if you forgot to fit it before the flywheel?
Or is there some production reason? As a press tool designer in a previous life the reason for the split always intrigued me, it was not like Ford to spend a tenth of a penny just to make life easier for forgetfull DIY mechanics.
