This repair kit fits Rexroth A4VG45 32 series closed circuit variable piston pump. We supply two types of kits: Seal Kit and Rotary Group Overhaul Kit.

OEM Reference Part Numbers

1. Seal Kit (Oil seals & O-rings only, for external leakage repair)

- R987054641: Seal kit for A4VG40 / A4VG45

Note: Original Rexroth does not have one single OEM part number for full rotary group kit. Core components are sold separately by original manufacturer.

 Rotary Group Overhaul Kit (Complete internal friction parts, for high internal leakage, low pressure and abnormal noise overhaul)
Contains: Cylinder block, piston & shoe assembly, valve plate, retainer plate, ball guide, thrust plate, disc springs, bearings and other wearing parts.

Basic Pump Specification

- Model: A4VG45, Series 32
- Displacement: 45cc/rev
- Type: Closed circuit variable piston pump
- Nominal pressure: 40MPa, peak pressure: 45MPa
- Common control version: EP / DA / HD

Application

- Concrete mixer truck (Most popular application, matched with A6VM hydraulic motor)
- Small road roller, asphalt paver
- Skid steer loader, compact tracked construction machine
- Underground mining vehicle

Notes

1. A4VG series is closed loop travel pump, different from A4VSO open loop pump.
2. To confirm correct kit, please provide full pump nameplate model and MNR number, such as A4VG45DA2D1/32R-NSC02F005. Left and right valve plates cannot be interchanged.
3. Seal kit solves external oil leakage; rotary group kit is for heavy overhaul when pump has internal leakage, insufficient pressure or noise.
