I mean, that's the engine, these are the two belts, but what are they for?

[Kedishen]

Vacuum pump. Yorks and very early di's had vacuum pump there.

[focarglo]

OK.
so...

is it correct as follows?

E - source of power for the two belts

belt 1 E-A-D
A - alternator
D - fan

belt 2 E-B-C
B - vacuum pump
C - water pump????

larger belt runs from the crankshaft pulley around the water pump and the alternator, smaller one runs from crankshaft around vacuum pump and small adjuster pulley. Oil pump is inside the engine at the front, driven by gears.

[focarglo]

so, the water pump is behind the fan?

[Muttley]

Yes.
