2000 Series Geroler Motor, 4.90 cu in/rev, 2 Bolt SAE A Mounting Flange, 1 in. Straight Keyed Shaft, 7/8-14 St.Thd. O-Ring Ports,

Description & Features

The Danfoss / Eaton Char-Lynn 2000 Series Disc Geroler Standard motor offers efficient performance with a displacement of 4.9 cu in/rev. Designed for applications such as swing motors, brush cutters, mowers, and harvesting equipment, this motor ensures reliability.

Equipped with a 2 bolt SAE A mounting flange and a 1 in. straight keyed shaft, the motor supports easy installation. The 7/8-14 St.Thd. O-Ring ports guarantee secure connections, while the motor's highly-efficient design provides significant energy savings.

Featuring the lowest pressure drop in the industry, the motor can operate at a maximum case pressure of 2000 PSI without a case drain. It is recommended to use premium quality, anti-wear type hydraulic fluid, and the fluid viscosity should be a minimum of 70 SUS at operating temperature. For optimal performance, break-in the motor for approximately one hour at 30% of rated pressure.

For reliable function, recommended filtration per ISO Cleanliness Code level 18/13 is advised. The motor also sustains a maximum operating temperature of 180deg; F.

Product Questions & Answers (5)

Question by: Curt R on Oct 2, 2025, 5:07 PM

Getting ready to put one of these on a brush cutter. Is there anything special i need to do before putting it to work full throttle?

Answer by: Customer Support on Oct 4, 2025, 6:12 AM

Filling the motor with fluid before applying any load is the first step. You will then want to run the unit for about an hour at 30 percent of its rated pressure. That short break-in period helps ensure the longest possible lifespan before you put it to heavy use.

Question by: Clint H on Oct 11, 2025, 9:21 AM

got a mower swing motor setup, are these ports the o-ring kind and what thread are they?

Answer by: Customer Support on Oct 13, 2025, 8:39 AM

Port-wise, it uses SAE O-ring ports with 7/8-14 UNF-2B straight threads, and the ports are staggered.

Question by: Roy J on Jul 26, 2025, 6:42 PM

does this motor need a case drain line, or can it handle back pressure on its own?

Answer by: Customer Support on Jul 28, 2025, 3:37 PM

Up to 2000 PSI, the motor handles case pressure without a case drain. Once you're running continuous back pressure above that threshold, you'll need to run an external case drain line and make sure it's plumbed so the motor case stays full of fluid at all times. That's a hard limit worth keeping in mind before you spec it into a high back pressure circuit.

Question by: Jean T on Aug 23, 2025, 5:20 PM

got a mower setup that takes a 2-bolt SAE A mount and a 1 inch straight keyed shaft. is this motor that exact combo?

Answer by: Customer Support on Aug 25, 2025, 6:48 AM

It matches that hardware: a 2 bolt SAE A mounting flange and a 1 in straight keyed shaft. Porting on this unit is 7/8-14 straight thread SAE O-ring ports, so your hoses or adapters need to match that style too.

Question by: Eddie M on Apr 27, 2025, 7:37 PM

What kind of hydraulic fluid should I be using in this motor?

Answer by: Customer Support on Apr 29, 2025, 8:11 AM

Premium quality, anti-wear type hydraulic fluid is recommended for this motor. You'll want to make sure your fluid viscosity is a minimum of 70 SUS at operating temperature.
