Bobcat hydraulic oil leak

[coolbrze]

Replaced the two o-rings & it's still spewing hydraulic oil. Would the banjo bolt be messed up or is it more likely that either the housing or tubing?

Can only guess, my guess would be the tubing end that the o-rings fit it. A good look at all surfaces should reveal something. Maybe a crack in the fitting or tubing, maybe a gouge.

A friend has a Bobcat CT235 tractor w/ FEL & he's got a hydraulic leak coming from a "bolt" under the right side floorboard. He said that it was misting out when he'd lift w/ the FEL but now it's spraying out pretty good. Is this common & does anyone know the P/N for the bolt that I can give him? Also, what kind/type of hydraulic fluid does the tractor take?

Units have history of tube cracking at banjo connector. Check for field mod at your dealer.:thumbsup:

That's exactly what it was. Looked at it earlier today & saw a hairline crack in the "hard line". What's field mod & how much does that cost vs. a new hard line? Any tips/tricks to installing either?

A field modification is a repair to correct a repeating failure or an improvement. In this case vibration is the issue. The field mod adds a piece of rubber and a clamp to dampen the vibration.

As a short term fix you can try braising or soldering it. Us good flux after you get it hot enough to burn off the oil. There was a post a long while back where a member replaced the tube with a good high pressure hose. His biggest issue was finding the correct banjo bolts that accepted hose fittings. Also look over on the KIOTI form as their units are twins of ours.

Anyone have a P/N for this hose? Bobcat ordered us the wrong one...

If you go to the Bobcat parts book on their web page you can look it up.

Is the hose in question a Bobcat hose or just a generic hose someone found to replace the tubing?
