Strato-lift MRX-25 Parts Catalog – Why You Need the Factory Document

If you are working on a Strato-lift MRX-25 and you are guessing which brake cylinder or cushion cylinder part number you need, you are wasting billable hours and risking a safety failure. I have seen technicians use aftermarket cross-reference charts that are off by a thread pitch, then wonder why the brake won’t release. This parts catalog is the factory-issued document – 38 pages of PDFs scanned directly from Strato-Lift’s own print. Every fitting, every hose length, every cylinder part number is listed in the B.O.M. tables. No third-party reinterpretation.

Brake Components and Cylinder Specs

Section 2 covers the drive chassis, and that includes Figure 2-D Brake Components, Figure 2-J Brake Cylinder, and Figure 2-K Cushion Cylinder. You get the exact part numbers for the brake cylinder assembly – not a generic “fits similar models” list. Page 4 gives you the full hydraulic diagram B.O.M. with all fitting designations from Parker. If you need to order a replacement cylinder, you match the figure number to the index and pull the OEM part number. I’ve had guys order a brake cylinder based on length alone and end up with the wrong port orientation. This catalog eliminates that.

What Does the MRX-25 Parts Catalog Cover?

It breaks down into five sections: Hydraulic Diagrams (Section 1), Drive Chassis Components (Section 2), Boom Components (Section 3), Platform (Section 4), and Decals and Placards (Section 5). Within Section 2 you get steer axle, drive axle, battery box, ground control panel, power unit function manifold, pump and motor, motor steering cylinder, brake cylinder, and cushion cylinder. Section 3 covers boom section, lift cylinder, lower boom arm, lower control arm, compression arm, upper boom arm, and upper control arm. Section 4 has platform rear, deck extension, and control box. Section 5 shows decal placement – skip that and you risk safety compliance issues. This is a parts catalog, not a service manual, so it tells you what part number to order, not how to fix it. That distinction matters.

38 Pages of Factory Diagrams

Each figure is a clear exploded view or schematic. You won’t find blurry reproductions or guessing games. The file is 38 pages total, with each figure numbered and indexed. For example, Figure 2-K shows the cushion cylinder with a callout and corresponding part number in the B.O.M. table. The table includes quantity, description, and the Strato-Lift part number. That is what you need to hand to your parts supplier. No need to decipher aftermarket part numbers that may or may not cross reference.

Get the Right Cylinder Part Numbers

You cannot afford to misorder a motor steering cylinder, brake cylinder, or lift cylinder because of stroke length or port angle. The catalog lists them by figure: Figure 2-I Motor Steering Cylinder, Figure 2-J Brake Cylinder, Figure 2-K Cushion Cylinder, Figure 3-B Lift Cylinder. Each figure has its own B.O.M. with the exact part number. If your machine has a serial number prefix, check the index for any notes – sometimes revisions happen. But the manufacturer’s own document stays accurate to the original build.

Hydraulic Diagram: Tracing the Lines

Page 4 is where the hydraulic diagram B.O.M. lives. It lists every hose assembly with exact lengths: Hose 1/4″ x 15 1/2 in. lg., Hose 3/8″ x 58 in. lg., Hose 1/4″ x 69 in. lg., and so on. Fittings are designated per Parker standards. If you need a flow control valve (part 002004) or a filter (part 002458), it’s right there. The diagram in Figure 1-A shows the hydraulic circuit flow. This is essential for troubleshooting – you trace the line, find the part number, and order the correct assembly. No generic “hydraulic hose kit” that never fits right.

Do not skip the decals section. Section 5 shows exactly where each safety placard goes – missing decals can lead to OSHA issues or operator confusion. The catalog gives you the part numbers for those decals too.

If you work on other models, the Strato-Lift TRX-13 Parts Manual covers the smaller lift, and the Strato-Lift SRX-20 Parts Manual handles the mid-range. For the newer version, see the Strato-Lift MRX-25N Parts Manual. Safety standards in the Automotive Industry Overview apply to industrial lifts as well – never bypass safety decals. The hydraulic system shares design principles with an Internal Combustion Engine’s lubrication circuit, but the part numbers are specific to Strato-Lift.

Does this catalog include torque specs?

No, this is a parts catalog, not a service manual.

How do I find the correct part number for the brake cylinder?

Flip to Section 2, Figure 2-J. The B.O.M. table lists the part number, description, and quantity. The brake cylinder is listed as part of the drive chassis components. If you need the cushion cylinder, it’s Figure 2-K. Cross-reference with your machine’s serial number to ensure compatibility. These factory diagrams show the exact orientation and mounting points, so you won’t order the wrong cylinder. Page 4 also shows the hydraulic line connections for brake circuit verification.
