TRAMMING HOSE KIT

770 109 09 TRAMMING HOSE KIT is the muscle that gets your rig moving across the bench or between drill patterns. It’s a hydraulic motor, plain and simple, taking the pressurized oil from your pump and turning it into rotational force for the final drive. Basically, it’s what makes the tracks or wheels spin, pushing tons of steel and components around the site. Without it, you’re stuck. It’s a workhorse, designed to handle the constant push and pull of moving a heavy machine over uneven ground.

When this motor starts to go south, you’ll definitely notice it. Usually, the first thing is a loss of power or speed on one side, making the rig pull hard to one direction when you try to tram straight. You might also hear a distinct whine or even a grinding noise coming from the motor itself, especially under load. Sometimes, the rig will just feel sluggish, like it’s fighting itself to move, and you’ll see the pressure gauge fluctuate wildly when you try to engage tramming. Don't ignore those signs; it's telling you something's wrong internally.

Look, when you're dealing with these, it's not just about swapping it out. Always check the final drive oil for contamination and metal shavings when you replace one of these motors; often, a failing motor can send debris into the gearbox. Also, make sure your hydraulic system's relief pressures are set correctly, and that your filters are clean. A new motor won't last long if it's fed dirty oil or forced to work against incorrect pressures. It’s a system, not just a single part.
