Bosch Rexroth 45- to 60-ton class hydraulic excavators Variable Plug-In Motor A6VE160
Control Options
1. A6VE160HD1 / HD2: Hydraulic two-position control; enables rapid switching between maximum and minimum displacement via external high/low-pressure hydraulic signals (commonly used for the high/low-speed travel function in excavators).
2. A6VE160HZ / HZ1: Electro-hydraulic proportional control; adjusts motor displacement proportionally via 24V/12V electrical signals, offering extremely high control precision.
3. A6VE160EP: Proportional electric control; a common choice for intelligent control systems in construction machinery.
Rexroth A6VE160 Variable Displacement Motor Overhaul BOM Detailed List
| No. | Component Name | English Description | Qty | Replacement Level | Remarks / Functional Description |
|---|---|---|---|---|---|
| I. Core Rotary Group Components (Must be replaced as a complete kit) | |||||
| 1 | Cylinder Block (Barrel) | Cylinder Block | 1 pc | Mandatory | The core housing where pistons stroke. Any internal scratches or face wear will cause catastrophic volumetric loss. |
| 2 | Piston Assembly (with Shoes) | Piston with Shoes Set | 7 pcs/set | Mandatory | Dedicated spherical pistons for 160cc displacement. If one is scored, all 7 must be replaced as a matched set. |
| 3 | Valve Plate (Port Plate) | Valve Plate | 1 pc | Mandatory | Controls high/low-pressure timing. The critical face seal surface determines motor volumetric efficiency (torque). |
| 4 | Drive Shaft (Main Shaft) | Drive Shaft | 1 pc | Inspect & Replace | Involute splined shaft (e.g., W50 series). Check for worn splines or damage to the front bearing seat. |
| 5 | Center Pin & Retainer Plate | Center Pin & Retainer Plate Kit | 1 set | Highly Recommended | Restricts piston shoe return and ensures proper centering alignment; a standard wear item during overhauls. |
| II. Bearings & Hydraulic Sealing System (To prevent external leaks and shaft wobble) | |||||
| 6 | Full Overhaul Seal Kit | Full Seal Kit / O-Rings | 1 set | Mandatory | Includes high-pressure, wear-resistant Fluororubber (Viton) / NBR O-rings, shaft oil seal, and shaped gaskets. |
| 7 | Front Shaft Bearing (Heavy-Duty) | Front Shaft Tapered Roller Bearing | 1 pc | Mandatory | Withstands reverse and dynamic loads from the gearbox. Excessive play causes shaft vibration and motor seizure. |
| 8 | Rear Shaft Bearing | Rear Shaft Support Bearing | 1 pc | Mandatory | Works with the front bearing to locate the drive shaft; highly recommended to replace during teardown. |
