Cat 310 pump leaking oil?

[coincarwash.ca]

My Cat 310 pump seems to be leaking oil and I don't know where from. I keep finding some oil on the floor under my pump stand. I look at the clear level indicator on the back and it seems low....I add more oil and after a few weeks it seems low again and oil is on the floor....what could it be?

It shouldn't be hard to find. The likely spots are the piston oil seals and the crankshaft seals. Just wipe it down well, overfill the oil a little and check it in an hour and you'll see where it's coming from.
