OIL FILTER

853 698 09 OIL FILTER is what keeps the crud out of your hydraulic or engine oil, depending on where it’s fitted. On a drill rig, you’ve got a lot of moving parts and high pressures, so keeping that oil clean isn’t just a nice-to-have; it’s absolutely essential. This thing catches all the tiny metal shavings, dirt, and carbon deposits before they can grind up pumps, valves, and cylinders. Think of it as the kidney for your machine’s blood – keeps everything flowing smoothly and prevents premature wear.

When one of these starts getting plugged up, you’ll usually notice a few things. First off, you might see a drop in system pressure or, worse, inconsistent pressure readings if it’s struggling to pass enough oil. Sometimes, you’ll get sluggish movements on the rig, especially with the feed or rotation, because the pumps aren’t getting the flow they need. If it’s really bad, the bypass valve might open, sending unfiltered oil straight through, which is when the real damage starts happening to your main components. You might even hear a change in pump noise, a kind of strained whine.

Changing these filters is pretty straightforward, but don’t just slap a new one on and call it a day. Always make sure you’re using the correct filter wrench to avoid damaging the housing or the new filter itself. And here’s a common one: always check the O-ring or gasket on the new filter. Sometimes they’re not seated right from the factory, or they get pinched during installation, leading to a slow leak you won’t spot until it’s made a mess and you’re topping up oil more often than you should be.
