Case SR130, SR150, SR175, SR200, SR220 2011 Service Manual

You’ve got a 2011 Case SR150 or SR200 in the bay with a hydrostatic whine, a fault code that won’t clear, and an aftermarket PDF that tells you to “check fluid level” and nothing else. That costs billable hours and burns trust. I’ve been turning wrenches 28 years, and I’ve seen more stripped bolt heads than I’ve had hot dinners. The only document that keeps a job on schedule is the factory service manual – the one you’re looking at right now. Case SR130, SR150, SR175, SR200, SR220 2011 Service Manual runs 1499 pages and covers every system from the hydraulic command network to the frame positioning controls. You don’t guess; you read the spec.

Hydraulic, Pneumatic, Electrical, Electronic Systems – Section A

This section is the backbone of any loader repair. Section A splits into Primary Hydraulic Power System (A.10.A), Secondary Hydraulic Power System (A.12.A), Hydraulic Command System (A.14.A), High-Flow Hydraulic Power System (A.16.A), Electrical Power System (A.30.A), Lighting System (A.40.A), Electronic System (A.50.A), and a full list of Fault Codes (A.50.A). If you need charge pressure specs for the hydrostatic pump on an SR175, you pull page numbers from the index – no translation errors, no aftermarket interpretation. One of my guys skipped the high-flow pressure check on an SR220 last month. Found the spec in under a minute. Fixed the leak. Done.

Engine and PTO In – Section B

Section B covers the Engine (B.10.A), Fuel and Injection System (B.20.A), Air Intake System (B.30.A), Engine Coolant System (B.50.A), and Starting System (B.80.A). The Case SR130 uses the same fuel injection timing values as the SR150? You confirm it here. Manual Transmission doesn’t apply to these loaders – they are hydrostatic – but the engine PTO coupling procedure is spelled out with fastener grades and torque sequences. No “tighten until snug” garbage. You get ft-lb values per bolt position.

Does This Manual Cover the Transmission?

Yes, it does. Transmission, Drive and PTO Out – Section C – dedicates a chapter to Transmission Hydrostatic (C.20.F). That’s the entire hydrostatic drive system for SR130 through SR220. If you’re swapping a pump on an SR200, the hydraulic/hydrostatic detailed views section shows line routings and port pressures. CASE SR130-SR250 Alpha Series Service Manual 2011 extends coverage to the Alpha series, but this 2011 manual is the one for these specific machines. Don’t mix them up.

Get the Right Torque Data – Axles, Brakes, Steering

Section D covers Final drive (D.15.A), Final drive Hydraulic drive (D.15.C), Steering Mechanical (D.20.B), Parking Brake Hydraulic (D.32.C), Wheels and Tracks – Tracks (D.50.B) and Wheels (D.50.C). The parking brake on an SR175 uses a specific hydraulic release pressure; the manual gives the psi value. Wheel lug nuts on an SR220 require 140 ft-lb. I’ve seen aftermarket docs list 120. That’s how wheels come off. Use the factory number. Manual Transmission might be a different lookup, but here it’s all about final drive and track tension. If you’re rebuilding a final drive on an SR150, the step-by-step in D.15.A includes shim selection and gear backlash specs.

Electrical Schematics: Two Separate Sections

They break the electrical into ELECTRICAL SCHEMATIC-EH and ELECTRICAL SCHEMATIC-MECH. One for electronic-hydraulic interface, one for the mechanical control circuit. You trace a no-start on an SR130? Start with section A.30.A for the power system, then jump to the EH schematic. Wire colors, connector pinouts, ground locations – all drawn from the Case factory drawings. No guessing which diode goes where. Case SR130-SR220 2011 Operators Manual – OEM Specs & Safety gives you operator-level info, but this service manual is for the guy holding the multimeter.

Frame Positioning and Tool Positioning – Sections F and G

Frame Positioning (F) covers boom and chassis leveling adjustments. Tool Positioning (G) includes hitch and working tool hydraulics. If your SR200 attachment won’t latch, section H (Hitch and Working Tool) shows the solenoid test procedure and flow rates. Case CX210B, CX230B, CX240B 2009 Service Manual – OEM Factory Specs is for excavators, but the wiring philosophy carries over – Case doesn’t change their logic across lines.

7 Major Systems, One Factory Source

This 1499-page manual covers seven lettered systems (A through H plus J for excavating and landscaping). It also includes the Hydraulic / Hydrostatic Detailed Views – a separate section with component cross-sections and port identification. You want the charge pump relief setting for the SR150? It’s in the detailed views. The page count alone tells you the depth: nothing is glossed over.

Who Needs This Manual?

DIY owners with an SR130 in the barn and professional shops running a fleet of SR175 and SR220 loaders. If you are a beginner and you’ve never cracked open a hydrostatic transmission, don’t start without the factory disassembly sequence. The manual gives you required tool lists, safety warnings (like pin block insertion before boom work), and OEM torque specifications. For the shop owner, this cuts liability – you hand the tech the spec, not a guess.

Does this manual cover the SR250 as well?

No. The SR250 is included in the Alpha series manual. This one covers SR130, SR150, SR175, SR200, and SR220 only.

What years does it cover?

2011 model year. Part number 84522363, first edition English, June 2011.

Are the wiring diagrams in color?

Factory schematics are black-and-white with component callouts. The EH and MECH sections each have separate diagram sets.

Can I use this for the SR150 track version?

The SR150 is a skid steer loader, not a compact track loader. If you have a track loader, look at the SV/TR models listed in the front matter. This manual focuses on wheeled machines.

I don’t recommend aftermarket manuals. I’ve seen them list the wrong oil viscosity for the SR175 hydraulic system. That burns pumps. You want the real thing – the OEM file that Case printed in 2011. Access the Factory Manual and put it on your shop tablet. It’ll outlast three rebuilds.
