Oil Pump Drive

Morning all. Came across a question on another forum about the standard 2.9 engine(non Cosworth) that intrigued me. A chap was asking if you could use the blanking unit which incorporates a drive gear for the oil pump (to keep it working) from the 4 litre cologne in the 2.9 to get rid of the distributor. Obviously he must be looking at using EDIS or something similar. I told him I have done this mod on my 2.9 many years ago (early noughties). Anyway question came up on how the oil pump is driven on the 24V. The exploded diagram on this forum shows the same drive gear but what confuses me is how that is now driven as the cams are now up in the heads. Can anyone shed a light? I have my spare BOB out in shed but dont want to strip it down as yet. John.

Found this on the "Ford Cologne V6 Engine" wiki page The standard Ford-issued block was machined differently to improve strength. In place of the single-cam arrangement, an endless duplex hydraulically tensioned timing chain was used to drive the overhead cams. The chain measured 2.2 m (7 ft 3 in).[3] The casting and bearings for the standard underhead cam were repurposed for a shaft which drove the oil pump. But doesnt tell me how they drive the oil pump. There is obviously something that replaces the old underhead cam but I cant imagine a shaft all the way back to front of engine to get a drive off the timing chains...or did they?

Looks as though you're probably right, have a look at the manuals here: https://www.fordscorpio.co.uk/CosV6manual.htm And pictures here: https://www.fordscorpio.co.uk/24vrebuild.htm I didn't see anything that shows in detail but presumably a shaft right through with a skew gear to the pump. You can also see the ridiculous shallow engagement of the chain with the pump sprocket – no wonder it jumps when the tensioners are worn.

On the dismantle pages you finally get to the bit where it tells you to remove the intermediate timing shaft sprocket, then bearing plate and you remove the intermediate shaft which as you say confirms my engineering guess of like a dummy cam spidle to drive the pump. Well this has certainly been an educational day. Cheers T. John.
