TN55S loader (33LA) cylinder leak questions

[mojoinco]

Hello Folks,

One of my bucket tilt cylinders started blowing massive amounts of hydraulic fluid. When under load (down pressure) or when returning to tilted back after being under load (more like it's cleaning out that side of the piston). There are 3 'bleed' holes on the upper part of the cylinder housing.

What purpose do they serve, and what is the symptom that the jet(s) of fluid should be telling me?

Made the faded blue on the other side look good - oh boy!

Thanks!

CNH website shows multiple bucket cylinders for a 33lA, Which one do you have?

Sounds like you blew a seal in the cylinder. The bleed holes allow the pressure to not build up where it isn't supposed to be in the cylinder. You can rebuild them yourself or take it to a hydraulic shop. Instead of buying the expensive NH seal kit they will just match everything up to generic seals and O-rings. Last cylinder I had rebuilt was on my hay grapple, cost me $100 which was less than the OEM seal kit.
