problem with dual ram tab
 

One of the hydraulic cylinders on a dual ram tab moves much slower than the other. To a lessor extent I have the same problem with a drive, one of the cylinders moves a little slower and doesn't seem to fully retract. How do I diagnose and fix- if it even needs to be ? There are no leaks. Thanks.

What brand tabs?

Kiekhaefer/ Mercury.

Seperate pumps for each ram?

Nope. Just the one pump.

It's a model 600c. Someone has some for sale in the "other parts and accessories" section of classifieds if you want to see them. Can't upload a pic now.

Probably a restriction on one of the lines, or the cylinder itself if they share the same pump.
