Australian 1965' Clark forklift C40 hydraulic fluid type

[Stuck in the past]

G'daye from the land down under'
i recently purchased a 1965 c40 clark forklift
If anyone could please help What would be the original/compatible hydraulic fluid type and also
the steering is on a separate belt drive hydraulic pump
I assume it would be the same fluid type'?
There are no markings or labels to indicate the types'
Cheers'

MS 68 I doubt there is a separate ps pump it has been a long time for me working on a Clark.

All of our forklifts run a generic ISO46. I have some new and some dating back into the 70s. They are usually just basic pumps, valves, and cylinders and don't need a really high end fancy fluid. The most important thing is to keep it clean.

ISO AW32 - pick your favorite flavor for brands. But just AW32 it seems for that unit.
