Strato-lift SRX-20 Parts Catalog

You’ve pulled a brake cylinder off a Strato-lift SRX-20 and the part number is worn off. You can either guess, order a generic replacement that won’t seat right, or spend an hour on the phone with a dealer who’ll send you a PDF of a blurry exploded view. I’ve been there. That’s why I keep a printed copy of the factory Strato-lift SRX-20 Parts Catalog on the bench — 60 pages of OEM part numbers, hydraulic flow diagrams, and breakout callouts that save you from buying the wrong fitting. This isn’t a reprint or a third-party compilation. It’s the actual PMV-0699 document Strato-lift issued.

Hydraulic Diagram – Figure 1-A

Every hose, fitting, and valve in the SRX-20 hydraulic circuit is mapped out on Figure 1-A. The B.O.M. note says all fitting designations are from Parker, so you can cross-reference exact thread sizes (1/4 MMS, 6 CTX, 4-4 CTX, etc.) instead of eyeballing threads at the parts counter. Need a 1/4 x 15 1/2 inch hose? Part number 002094 is listed with quantity. The diagram also shows the flow path from pump to manifold, steering cylinder, lift cylinder, and brake cylinder. If you’re rebuilding a power unit or chasing a leak, this single page saves you from pulling the wrong hose.

Drive Chassis Components – Brake Cylinder and Steering Axle

Section 2 covers all drive chassis hardware: steering axle, steering linkage, drive axle, brake components, battery box, ground control panel, power unit manifold, pump and motor, steering cylinder, brake cylinder, and cushion cylinder. Each figure (2-A through 2-N) breaks down assemblies with labeled part numbers. The brake cylinder section shows you exactly which seal kit or cylinder assembly fits the SRX-20 before serial number 20521 and after. No guesswork. You match the figure, order the part number, and move on to the next job.

Boom Components – Section 3 Coverage

Figures 3-A through 3-G detail the boom section, lift cylinder, lower boom arm, lower control arm, compression arm, upper boom arm, and upper control arm. If you’re replacing a lift cylinder or chasing a worn pin, these exploded views tell you which bushing goes where. The manual doesn’t give you assembly torque specs — it’s a parts catalog, not a service manual — but it does give you the correct OEM part numbers so you don’t end up with a Chinese knockoff that fails under load.

Platform and Decals – What’s in Section 4 and Section 5

Section 4 covers the platform assembly: platform, rear platform deck extension, and platform control box. Four figures (4-A through 4-D) show how the platform mounts and which switch or joystick part to order. Section 5 is a decals and placards location page (Figure 5-A). If you’re restoring an SRX-20 or need to replace faded safety labels, that figure tells you exactly where each decal goes and what part number to order. Saves you from buying a generic warning sticker that doesn’t match the factory layout.

Why Factory Parts Catalog Beats Aftermarket Lookups

I’ve seen aftermarket parts catalogs that list a single “brake cylinder” part for all serial numbers and then you get the wrong mounting bolt pattern. This Strato-lift manual uses OEM part numbers tied to specific serial number breaks (e.g., before serial number 20521). The hydraulic diagram references actual hose lengths and fitting types. You don’t get that from a third-party site that scraped data. The Automotive Industry Overview might give you general trends, but it won’t tell you that the steering cylinder return line hose is 1/4 x 60 1/2 inches. Only the factory catalog does.

Frequently Asked Questions

Does this manual include torque specifications or repair procedures?

No. This is a parts catalog. It gives OEM part numbers, exploded diagrams, and quantities — not assembly torques or step-by-step repair sequences. You need a separate service manual for that.

What serial numbers does this catalog cover?

The hydraulic diagram and some brake components reference “BEFORE SERIAL NUMBER 20521”. Later serial numbers may use different fittings.

Can I use this to order parts from Strato-lift directly?

Yes. The part numbers are the same numbers Strato-lift uses. Hand the catalog page to your dealer or paste the number into their system.

Does the platform section include wiring diagrams for the control box?

No — the platform section covers mechanical parts only. Electrical schematics are in the service manual, not this parts catalog.

You want to fix an SRX-20 right. The only way to guarantee you get the right brake cylinder, hose, or boom arm is with the factory part number tied to that machine’s build. This 60-page PDF gives you every figure, every callout. Access the Factory Manual and keep it on your tablet or print it for the toolbox.
