Hello, my TB260's hydraulic pump is leaking pretty bad when either the Arm cylinder or slew motor is under load. Here's a little video: New video · Sunday, Sep 28 Tap to view! photos.app.goo.gl Hydraulic functions operate normally and with good power. Curious if those with experience say this involves a full rebuild, or just seals? Thanks, john
Wow I seen the video, and you will need seals minimum, but would suggest you start out with pulling your Hydraulic filter and cutting open to see what is in it. Pump may be good inside or toast inside. Best to find out if or how much metal wear happened inside. I have never had one apart but it needs rebuild or replacement. Please let us know what you find out. Simon C
Watched video a few times, not sure where oil is leaking. Could be a line or a fitting. I was having to tilt my head and figure out gravity all over again. Will watch a couple more times after my head stops spinning. lol
First i think your pump is not leaking, but through gravity and as pump comes in between, it lookslike pump is leaking. check your connections, check for hose. as at normal rpm it gives no leaks. probably wrong torque value.
Got lucky on this one, it was a loose fitting on top on the gear pump. Somehow the nut on the T fitting worked loose.
Thought so. apply correct torque value
