LUB TANK ASS

LUB TANK ASS 2710 0003 77 is basically where your rig's air-line lubricator gets its oil. It holds the lubricant that gets atomized into the compressed air stream, which then goes on to oil up your rock drill, hammer, and other air-driven components. Without a steady supply from this tank, those critical moving parts would run dry pretty quick, leading to premature wear and tear on expensive bits of kit. It’s a simple setup, but absolutely essential for keeping the drill string and percussion system happy.

When this tank starts giving you grief, usually it's not the tank itself failing, but issues related to it. You might see the air-line lubricator struggling to pick up oil, or maybe it's just not feeding consistently. What you’ll notice on the rig is often a drop in percussion power, or the drill bit getting stuck more often because the hammer isn't getting its lube. Sometimes, if there's a crack or a bad seal on the tank, you'll just find oil leaking all over the place, making a mess and obviously depleting your lubricant supply way too fast. Keep an eye on your oil consumption; if it suddenly spikes or drops, that's a red flag.

Replacing this assembly is usually pretty straightforward; it's mostly a bolt-on job. Before you swap it out, though, always double-check the lines leading to and from the tank, especially the suction line to the lubricator. Sometimes a clogged filter or a kinked hose is the real culprit, not the tank itself. Also, make sure you're using the correct type of rock drill oil. Using the wrong stuff can cause foaming or poor atomization, making it look like the tank or lubricator is bad when it's just the wrong fluid. Don't forget to properly bleed the system after refilling to avoid air pockets.
