Where are the hydraulic ports on a final drive motor?
The flow and return ports are typically going to be the two ports with the largest diameter and will connect to a matching pair of steel pipes or rubber hoses. If more than two ports are present, one of the lines will most likely be a case drain line . All piston-type hydraulic motors are going to leak hydraulic fluid from the rotator group.
Where is the case drain line on a final drive motor?
This hydraulic fluid must be returned to the hydraulic tank under minimal pressure. That is the purpose of the case drain line, which runs from the travel motor to the hydraulic tank. Note that this is a low pressure line and is where you will find the case drain filter, which we have discussed in other blog posts.
Where is the brake line on a final drive motor?
The speed line connects to the speed port, which is going to be the smallest port and may be on the back side of the travel motor or final drive. A brake line port may also be present and will be on the side or behind the main housing. This is one of the smaller lines, and should only be pressurized when the travel lever is in operation.
What should I do before installing a hydraulic system?
No grinding or welding operations should be done in the area where hydraulic components are being installed. All cylinder, valve, pump and hose connections should be sealed and/or capped until just prior to use. Mineral spirits should be kept in safety containers. Air hoses can be used to clean fittings and other system components.

How can you tell when a hydraulic hose needs to be replaced?
Inspect your hose for signs of wear or cracking. Stress, heat, sunlight, and normal wear and tear all degrade hydraulic hoses. Check the surface of your hose units to see what sort of shape they’re in. If you see cracking or tearing, replace this hose. Signs of wear include cracks, tears, and abrasions.
