Hi, thanks for the replies.

Keith, a setup as shown in the model is not wholly unusual for a 24 valve engine with 12 push rods, typically it is employed for slower speed engines. An image shows this below:

From responses on other forums, the part appears to be a scavenge dry sump oil pump. I will be checking this over the coming week though to confirm. The alternator could be mounted on the same shaft, or be oil cooled, again, need to check.

It seems impossible to say without reference to the manufacturer's literature. It does not fit the normal description for a fuel pump, oil pump, air con compressor, alternator, starter motor, air injection pump, hydraulic PTO pump or brake vacuum pump. It is odd because is it very large in scale to the rest of the engine and is geared to run very fast.

The location and the shallowness of the sump would tend toward a dry sump oil pump but it seems huge for that task and a bit lacking in plumbing. If you can find out what kind of engine it is and google the oil pump image you might get lucky.

As it is a drawn engine and not a photograph, though, it is possibly a figment of the drawer's imagination, is it not?

If its a truck motor, could it be a hydraulic pump. At first I thought of a hydraulic motor for starting, but that wouldn't work, you need the motor started to get hydraulic pressure. If it is it seems a bit high geared.
