If you're in the hydraulics aisle, the real question is whether you need a motor to convert fluid pressure into rotation, or a power unit to move fluid for a dump trailer. The two products here look similar in price but serve completely different jobs. Let's sort out which one fits your work.
The quick verdict: If your Char-Lynn Eaton 104-1065 motor is worn out and you need a direct replacement, the cast iron motor at $228.52 is the straightforward fix. If you're building or repairing a dump trailer with remote control lift, the $240.00 20-quart double-acting power unit is the complete package. The motor is 5% cheaper, but the power unit includes the tank, pump, and remote control.
| Feature | 104-1065 Hydraulic Motor | 20-Quart 12V Power Unit |
|---|---|---|
| Price | $228.52 | $240.00 |
| Component | Hydraulic motor (cast iron) | Double-acting pump with 20-quart tank |
| Flow / Pressure | 30.38 GPM max flow, 17 MPa rated pressure | 0.91 GPM, 3200 PSI port A, 1500 PSI port B |
| Extras | Motor and key lock | Handheld remote, 15-ft pendant, extra SAE #6 fittings |
| Best for | Replacing a Char-Lynn Eaton 104-1065 motor | Dump trailer power-up / power-down |
Where each wins
The hydraulic motor wins on price and power density: it delivers 14.5 kW and 625 N·m at 577 RPM, making it a strong replacement for existing hydraulic motors with the 104-1065 pattern.
The power unit wins on completeness: it includes the 20-quart metal tank, 1.6 kW 12V DC motor, SAE #6 ports, and a remote pendant, so you don't need to source separate components.
Hydraulic Motor New Cast Iron Motor For Char-Lynn Eaton 104-1065 Hydraulic Motor
This motor is built as a direct replacement for Char-Lynn Eaton 104-1065 applications. The cast iron housing is finished in black and the package includes the motor plus a key lock. It's rated for 115 LPM (30.38 GPM) maximum flow, 195 CC displacement, and 17 MPa rated pressure, with 625 N·m of torque at 577 RPM. If your existing motor matches these mounting and performance requirements, this is a straightforward swap at $228.52. The main limitation is that it's a motor, not a pump - it won't pressurize a hydraulic system or lift a trailer on its own. It also doesn't come with a remote control or reservoir, so you'll need to retain those from your existing setup.
20 Quart Double Acting Hydraulic Pump 12V DC Dump Trailer Hydraulic Power Unit
This power unit is a self-contained hydraulic system for a dump trailer. It's a double-acting pump with a 5-gallon (20-quart) metal tank, a 1.6 kW 12V DC motor, and SAE #6 ports. It's rated to 3200 PSI on port A and 1500 PSI on port B, with a flow rate up to 0.91 GPM. The kit includes a 15-foot remote control pendant, a handheld remote, and two extra SAE #6 fittings, so you can operate power-up and power-down from a distance. At $240.00, it costs about 5% more than the hydraulic motor, but it includes the tank, pump, and remote as one package. The trade-off is that it's a low-flow unit designed for dump trailer duty, not a high-speed motor replacement - and it's not the same part as a Char-Lynn Eaton motor.
Final choice by use case
Choose the 104-1065 hydraulic motor if you already have a hydraulic pump and tank and just need to replace a rotating motor - the cast iron build and 625 N·m torque make it a solid direct swap. Choose the 20-quart dump trailer power unit if you're adding a dump bed to a trailer or replacing the entire power system; the included remote and tank get you operating in no time, and the double-acting ports handle both raise and lower.
