Oil & Fuel Hydraulic Fluid Level - L3400

   / Hydraulic Fluid Level - L3400 #11  
I'm suspecting that I've been overfilling. Not good.

I would not worry. Back some years ago when there a lot of complaining about the ratchet noise of the old style cams Kubota instituted a change. They way over filled the hydraulic fluid to dampen the noise. I think the kit added a dip stick in the back since the sight glass would be useless.

Based on that, I don't think over filling will hurt anything except you won't see the level on the sight glass. In that case if it is all white it is low, if all a light yellow, it is full.

That's quite a relief to know about the overfilling, CCSIAl. I did go ahead and pulled the return line and let it pump out about 2 quarts. Fluid level still covers the sight glass, but I'll let it sit for a while and recheck it.

And yes, it is all yellow. But it's a relief to know that at least some overfilling won't likely blow the seals. I sure wish mine had come with the dip stick like the mod in the TSB.

this is what they did to mine and seems to work fine but the racheting can still be heard, albeit not as loud. what i don't like is the end of the dipstick protrudes from the cover and my boot sometimes catches it when i get on/off the tractor.
