Bosch Rexroth A6VM variable hydraulic motor for the Dieci Telehandler BHN1126 BHN1171

The A6VM is a variable displacement axial piston motor in a bent-axis design. It's one of Bosch Rexroth's best-known motors for mobile and industrial hydrostatic drives. It converts hydraulic flow and pressure from a closed-circuit pump into rotary torque at the output shaft.

How a Variable Motor Works in a Telehandler Drive

Large displacement: torque mode

When the swivel angle is high, the motor swallows more oil per revolution. Output speed drops and torque rises. This is your "low range" feel: climbing grades, pushing into a stockpile, or pulling away with a loaded fork.

Small displacement: speed mode

When the swivel angle is reduced, the same flow spins the shaft faster, but with less torque. This is your transport mode, where the machine moves quickly along flat ground.

Why not just use a gearbox?

Many telehandlers do pair a hydrostatic motor with a mechanical gearbox, and the variable motor reduces how much shifting the operator needs. A wide displacement range means smoother speed changes and often fewer mechanical gear steps. It also lets the engine run in its efficient RPM band while the hydraulics handle the ratio.

Why Rexroth A6VM Motors Suit Dieci Machines

Dieci telehandlers work in demanding conditions: farms, quarries, construction sites, and industrial yards. The drive needs to handle:

Frequent direction changes (forward/reverse shuttle work)

Heavy starting loads with a raised boom

Dust, mud, and temperature swings

Long duty cycles with inconsistent maintenance

A bent-axis variable motor from an established manufacturer offers robust bearings, proven control options, and good parts availability across Europe and North America.

Maintenance Habits That Extend Motor Life

Keep the oil clean

Contamination is the leading killer of axial piston units. Rexroth specifies cleanliness classes per ISO 4406 for A6VM motors, so follow the datasheet for your series. Use quality filters and replace them on schedule, not when someone remembers.

Respect viscosity and temperature

Use the hydraulic oil grade specified by Dieci. Running a machine hot for long periods thins the oil, accelerates internal wear, and shortens seal life. Keep the cooler clean, especially in dusty ag environments.

Fill the case before first start

After installing a replacement, fill the motor housing with clean hydraulic oil before starting. A dry start can damage bearings and piston surfaces within seconds.

Break in gently

Run a new or rebuilt motor under light load for the first period of operation, and check for leaks, noise, and temperature.

Q1: How long should an A6VM last in a telehandler?

A1: With clean oil, proper cooling, and sensible operation, these motors can run for many thousands of hours. Neglect, contamination, and overheating shorten that dramatically.

Q2: Where do I find the model information?

A2: On the nameplate attached to the motor housing. It lists the type designation and material number, which you'll need when ordering parts.

Q3:What is the price and delivery time of the Rexroth A6VM motor for the Dieci Telehandler?

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