I think I remember that the b230f oil pump in the 240's is driven with a slot setup on the end of the distributor shaft. The distributor being driven by a gear on the intermediate shaft.

The b230f in the 7/9 series has the distributor driven by the cam. What is the setup in the 7/9 cars for driving the oil pump?

When putting a b230ft into a 240 car there isn't room for the cam mounted distributor so an intermediate shaft and distributor from a 240 has to be installed. Once that is done does it interfere with the original oil pump setup on the b230ft?

I had always thought I would get around to installing a b230ft in a 240 and actually gathered some of the parts to do that. However, life got in the way and I am no longer looking for a project like that. I just recently wondered how the oil pump drives differed on those two engines.

When Volvo changed to the OHC redblocks, they made it with 2 drives, 1 for the distributor and 1 for the oil pump so they are 2 separate shafts driven by the intermediate shaft.

Early B21's got a metal plate to hold the oil pump drive gear down.

When Volvo added a breather box to the OHC engines, it holds the oil pump drive gear down.

So I have an intermediate shaft from a 240 and it incorporates the gear that drives the distributor (that in turn drives the oil pump).

How does the intermediate shaft from a 7/9 engine drive the oil pump? I am under the impression that because the gear isn’t needed for the cam driven distributor it was eliminated on the intermediate shaft.

When moving the distributor to the block of a b230ft (using a shaft from a 240) how is the oil pump driven?

The intermediate shaft for the 240s and early 700s have 2 helical gears cut into them and there are 2 separate drive gears, 1 towards the front of the engine to drive the distributor and the other towards the rear of the engine that drives the oil pump.

Your response that indicated there were two gears on the 240 intermediate shaft came as a surprise to me. I learned that was due to the fact I was relying on my memory which I have learned is not as reliable as it once might have been.

I decided to seek out that shaft I had pulled from a 240 and refresh my memory.

Thanks for taking the time to respond to my question.
