Another forklift question

[Righty Tighty]

The lift in question is an older Cat V60B, manual transmission. I haven't been able to find much info on the unit by searching the serial number, seems the Cat dealers don't offer support for ones this old.

There are two reservoirs for hydraulic fluid -- one for the cylinders and one that presumably feeds the transmission and power steering. After running for several minutes, the fluid in the rear reservoir becomes foamy. It's not overfilled. What could cause this? A leaky hose sucking in air? Turbulence inside the transmission?

The lift tends to lose power after running for a while, I'm guessing the foamy fluid has something to do with this. After sitting for an hour, the fluid returns to normal with no foam.

I added Hydraulic fluid to one of our skid loaders and had the same issue. Come to find out it took motor oil in the hydraulic unit. Works great now. Find an old farmer they usually know. Our skid loaders are not that old. 70XT and a 60XT. I believe that Oil drip in the picture designates Oil not fluid.

I would search for a manual for it, invaluable information. Ebay or there are companies that specialize in manuals.

Thanks to both of you for the replies. I picked up a manual from eBay not long ago, I'll flip through it to confirm fluid and/or oil type.

The power steering pump doesn't sound happy either, and I'm thinking incorrect fluid could explain these things. I'm hoping it's as simple as that.
