Rexroth A6VE bent-axis variable hydraulic motor for the Volvo Engineering Equipment 14326003 14569653 80640238 RM80610884 RM80778426

The A6VE is a high-pressure hydraulic motor from Bosch Rexroth (the Rexroth brand within Bosch). It is built for mobile machinery and works in open and closed circuits. Its main features:

Bent-axis axial piston design: the cylinder block sits at an angle to the output shaft.

Variable displacement: the swivel angle can change under load, which changes the motor's speed and torque.

Compact, robust housing: suited to travel drives, winches, and other mobile applications.

Series 6 platform: sizes typically run from about 28 to 160 cm³ per revolution, with nominal pressures in the 400 bar class. Confirm exact figures for your size on the current Rexroth data sheet.

Where the A6VE Fits in a Volvo CE Driveline

Volvo CE machines combine mechanical, hydrostatic, and electro-hydraulic systems depending on the product line. Variable motors like the A6VE are typically used in:

Hydrostatic Travel Drives

In a closed-loop hydrostatic transmission, a variable pump feeds one or more variable motors. Shifting the motor to a low displacement gives transport speed, and a high displacement gives tractive effort for working.

Compact and Specialty Equipment

Compaction equipment, compact loaders, and similar machines often use hydrostatic drives where a variable motor gives two-speed or continuously variable travel.

Auxiliary Drives

Fan drives, winches, and attachment circuits can also use variable bent-axis motors where speed and torque need to adapt to load.

Signs the Motor Is Failing

Loss of travel speed or power, especially when hot

Excess case drain flow, which signals internal wear

Whining, knocking, or growling noises

Overheating of the hydraulic oil

Metal particles in the filter or oil sample

Machine creeping or poor holding in neutral

A Quick Diagnostic Sequence

1. Check oil level, condition, and filter status.

2. Measure case drain flow against the specification for that size.

3. Verify pump output and system pressure before blaming the motor.

4. Test the control signal or pilot pressure.

5. Inspect for contamination, which is the leading killer of piston motors.

Maintenance Practices That Extend Motor Life

Keep oil cleanliness within the manufacturer's target ISO code.

Use the recommended hydraulic fluid and viscosity range.

Avoid running the machine hot for long periods.

Prime and fill the motor case properly after any service.

Replace filters and breather elements on schedule.

Q1: Is the Rexroth A6VE the same as the A6VM?

A1: No. They belong to the same bent-axis family, but they differ in size range, controls, and design details. The A6VM covers a wider size range with additional control options. Check the data sheet for your exact model.

Q2: What causes premature failure?

A2: Contamination, overheating, cavitation from low inlet pressure, and incorrect case fill are the most common causes.

Q3: What is the price and delivery time of the A6VE hydraulic motor for Volvo Engineering Equipment?

A3: The specific price and delivery time will depend on the equipment model or specific product model you provide.
