Heavy Duty Hydrostatic Motor, 3.32 cu in/rev, SAE C 4-Bolt Mounting Flange, 14T SAE C Splined Shaft, 1 Inch Code 62 Ports, PSI High Pressure Relief

This Eaton Heavy Duty Hydrostatic Motor is marked with the same C1JM20 catalog number, so it should be a direct replacement assuming your existing motor also has a SAE C 4-bolt mounting, a 14T SAE C splined shaft, and 1 Inch Code 62 ports.

Peak pressure ceiling on this motor is 6000 PSI, but that rating comes with an important condition. Pressure spikes at that level should stay under 1% of total operating time. Sustained operation at peak pressure will shorten the service life, so if your system regularly sees hard pressure events, keeping normal running pressure well below that ceiling is the smarter call. The cast iron housing helps absorb stress and reduces noise, but the 6000 PSI figure is a ceiling, not a target.
