Important Compatibility Information
Please Read Before Purchasing: This master cylinder is NOT a direct replacement for:
- **Wagner Power Master Cylinders:** These have a flat-style piston and a special reaction piston in the cylinder & flange that is also flat. Our unit features a 2 1/2″ depth piston.
- **Mico Cylinders:** While genuine Mico cylinders will have “MICO” stamped directly on the casing, some Mico units were built using a Wagner housing, which may be stamped with a 2704 casting number. It is critical to confirm that the master cylinder you are replacing does **not** have Mico internal parts, regardless of the casting number on the housing. Both Mico and Wagner cylinders utilize a special reaction piston in the cylinder & flange that is flat. For Mico replacements, please see part number M100135.
For motor graders and other heavy equipment, it is critical to verify your existing piston type. See the last picture for a visual comparison.
