2077526 Wirtgen Hydraulic Conveyor Motor - Bent-Axis Piston - W200 / W210 Cold Miller - Replaces 2310115

Hydraulic Conveyor Motor for Wirtgen W200 / W210 — Replaces 2077526

Direct replacement hydraulic drive motor for the discharge conveyor on Wirtgen W200 and W210 cold milling machines. German-engineered bent-axis piston motor — the same OEM specification installed at the factory. Replaces Wirtgen part numbers 2077526 and 2310115. In stock and ready to ship at a fraction of the dealer price.

The Problem

Your Wirtgen miller's discharge conveyor has stopped running — or it's slowing down, overheating, and losing power. The hydraulic motor that drives the conveyor belt has failed. Without it, milled asphalt piles up in the drum housing and the entire milling operation stops. Wirtgen dealers quote $7,500–$8,200 for the replacement motor, and their lead time can be weeks. Meanwhile, your road crew, traffic control, dump trucks, and paving crew are all sitting idle. A milling machine down on an active road project costs $10,000–$25,000+ per day in lost production, crew standby, liquidated damages, and DOT penalties.

The Solution

This is the identical OEM-specification bent-axis piston hydraulic motor used in the Wirtgen W200 and W210 cold millers. Same German engineering, same performance rating, same mounting configuration — direct bolt-on replacement. The bent-axis design delivers the high torque density required to drive a loaded conveyor belt throwing tons of milled asphalt per hour into haul trucks. Replaces Wirtgen 2077526 and superseded part number 2310115. We offer it at $4,950 — saving you over $2,500 vs the dealer price.

Why Buy From Trenchwell?

• Save $2,500+: Wirtgen dealers charge $7,500–$8,200 for this motor. We offer the identical OEM-spec motor at $4,950 — same German engineering, massive savings.
• OEM Specification: This is NOT a cheap aftermarket motor. This is the same bent-axis piston motor installed at the Wirtgen factory. Same displacement, same mounting, same performance rating. Built by one of the world's leading hydraulic motor manufacturers.
• Milling Downtime is Devastating: A cold miller down on an active road project costs $10,000–$25,000+ per day. Crew standby, traffic control, dump trucks idling, paving crew waiting, DOT penalties — it adds up fast. A $4,950 motor that ships today is a no-brainer.
• Expert Support: Hydraulic motors must match your system pressure and flow. Contact us with your Wirtgen model and serial number — we'll confirm the exact motor specification before you order.
• Fast Shipping: In stock and ready to ship. We understand that milling machines don't break down at convenient times. We ship the same day when possible.

Symptoms of a Failed Conveyor Motor

• Conveyor belt stops running or turns intermittently
• Conveyor speed drops significantly under load
• Hydraulic fluid leaking from the motor housing or shaft seal
• Motor makes grinding, whining, or knocking noises
• Motor housing is excessively hot to the touch
• Milled material backing up in the drum housing (conveyor can't keep up)
• Hydraulic system pressure spikes when conveyor engages

Installation Notes

• Shut down the machine and relieve all hydraulic pressure before working on the conveyor system
• Lock out/tag out per site safety procedures — milling machines have multiple hydraulic circuits
• Cap all hydraulic lines immediately upon disconnection to prevent contamination
• Photograph the existing motor orientation, port positions, and hose routing before removal
• Remove the mounting bolts from the SAE flange and disconnect the hydraulic lines
• Slide the motor off the splined shaft — if stuck, use a puller, do NOT pry on the housing
• Install the new motor in the same orientation — align the splined shaft and seat the flange
• Torque the flange bolts to the spec in your Wirtgen service manual
• Reconnect the hydraulic lines to the correct ports — check for cross-port reversal
• Fill the motor case with clean hydraulic fluid before starting (dry start = instant damage)
• Start the machine and run the conveyor at low speed with NO LOAD for 5 minutes
• Check for leaks at all connections and the shaft seal
• Gradually increase to full speed and verify conveyor performance under load

Frequently Asked Questions

Is this the same motor the Wirtgen dealer sells for $8,000?
Yes. This is the identical OEM-specification bent-axis piston motor — same displacement, same mounting, same pressure rating, same German manufacturing. The only difference is our supply chain, which allows us to offer it at $4,950 instead of the $7,500–$8,200 dealers charge. You save $2,500+ on the exact same motor.

What is a bent-axis piston motor?
A bent-axis motor uses a cylinder block angled relative to the output shaft. As hydraulic fluid pushes the pistons, the angled arrangement converts linear piston motion into rotational force. Bent-axis motors are preferred for conveyor drives because they deliver higher torque density and better efficiency than gear motors or vane motors, especially under the heavy, continuous loads of a milling operation.

My conveyor is slowing down but still works — is the motor failing?
Likely yes. As the internal pistons and valve plate wear, the motor loses volumetric efficiency — it leaks internally, so less flow converts to rotation. You'll notice the conveyor slowing under load before it fails completely. Replace it proactively before it leaves you down on a job.

Can I just rebuild my existing motor?
Possibly, but rebuild kits and labor typically cost $2,000–$3,500 and require 1-2 weeks of shop time plus shipping both ways. A new motor at $4,950 is often the better economic choice — zero downtime risk, full warranty, and no worn housing or case to worry about.

How do I verify I have the right motor?
Check your Wirtgen parts book for part number 2077526 or 2310115. You can also look at the tag on your existing motor for the displacement (28 cc/rev) and verify the SAE flange size and spline count. Contact us with your Wirtgen model and serial number for exact confirmation.
