Ford 1120, 1220, 1320, 1520, 1720 Workshop Manual

I lost count of how many jobs went sideways because somebody grabbed a generic manual or a reprint that had the wrong torque spec. That won’t happen with this Ford 1120, 1220, 1320, 1520, 1720 Workshop Manual. It’s the factory document — the same one dealer techs used when these tractors were new. 133 pages of actual engineering data, not some third-party rewrite that leaves out half the steps. If you’re touching a bolt on any of these five models, you want this open on the bench.

Engine Overhaul: Cylinder Head and Timing Gear Coverage

For the engine section you get the full rundown on cylinder head R&R, valve clearance adjustment, camshaft and cam followers, timing gear case removal, and rod/piston units. The index shows specific paragraphs for each model — 1120, 1220, 1320, 1520, and 1720 — so you’re not guessing which procedure fits your tractor. Each operation lists the parts you need to remove first and gives the orientation marks for timing gears. You’ll find the valve clearance specs in the text, not buried in an appendix. Page 30 is where the cylinder head work starts for the smaller models; the 1720 procedures are right next to them in the same section. That kind of layout saves you flipping back and forth.

Hydraulic Lift System: Flow Control Valve and Relief Valve Specs

Hydraulic problems are where most DIY guys throw in the towel. This manual covers the hydraulic lift housing, pump R&R, fluid and filter service, hitch adjustments, and troubleshooting. There’s a dedicated section on the flow control valve, check valve, and safety relief valve — all with testing pressures listed in psi (Imperial units). If you need to set the system relief valve, the spec is on the page for your model. The remote control valve coverage runs from page 172 for the 1120 models up through the 1720 variants. Page 73 gives you the water pump R&R steps for the 1720, which shares the same hydraulic pump mount as the 1320 and 1520. Knowing that cross-reference alone can cut your diagnostic time in half.

Does This Manual Cover the Electrical System?

Yes. The electrical section includes alternator and regulator, engine fuel stop solenoid, glow plugs, safety start switches, and the starting motor with solenoid. Each component has a table showing which pages apply to each model. For example, the starting motor removal is on page 81 for the 1120 and 1220 models, page 82 for the 1320 and 1520, and page 82 for the 1720 as well. The wiring diagrams are schematic-style, not simplified cartoons. You get wire colors and connector pinouts where applicable. If you’ve ever chased a no-start condition caused by a bad safety switch, you’ll appreciate the factory diagnostic procedure listed right there in the index under “Safety Start Switches” (page 80 for all models).

3 Sections You Need to Bookmark First

Fuel System Bleeding (page 53). These diesels are picky about air in the lines. The manual walks you through filter replacement and bleeding in the correct order — you don’t crack the wrong line and spray fuel everywhere. Clutch Adjustment (page 86). Single and dual plate clutch adjustments are listed with pedal free-play specs in inches. If you skip measuring free-play, you’ll burn up the throwout bearing inside 50 hours. Brake Adjustment (page 142). The brake adjustment procedure is the same across all five models, but the step order differs if you have a creeper gear option. The manual flags that difference in a note alongside the adjustment table.

Source Authenticity: Factory Ford vs Aftermarket Copies

I’ve seen reprints missing entire pages of hydraulic flow diagrams. This is the original OEM file — scanned from a dealer master copy, not a photocopy of a photocopy. The page numbering matches the factory binder, and the index covers models 1120 through 1720 without gaps. There is no aftermarket translation errors; the torque specs are in foot-pounds and inch-pounds as Ford published them. If you’re comparing this to a generic manual that says “tighten until snug” — throw that one away. OEM data is the only data you put on a torque wrench. Check the Automotive Industry Overview for more on why factory documents matter. For other Ford models, the Ford 6.4L Workshop Manual – OEM Torque Charts & Wiring uses the same factory format. Need a compact tractor manual? The Ford Fiesta 2011 Workshop Manual – 730 Pages of Factory Body & Paint Specs is a different beast but follows the same OEM structure. And if you work on passenger cars, the Ford Mondeo 2003 Workshop Manual – OEM Factory Specs | 2255 Pages shows how thorough Ford documentation gets. Here is an external resource: Automotive Industry Overview.

What models does this manual cover exactly?

Ford models 1120, 1220, 1320, 1520, and 1720. Also includes the 1920 and 2120 in some sections, but the primary coverage is the five listed in the title.

Are the torque specifications in Imperial units?

Yes. All torque specs are in foot-pounds or inch-pounds as Ford intended. No metric conversions from aftermarket editors.

Does the manual include wiring diagrams?

Yes. The electrical section has schematic-style wiring diagrams for the starting, charging, and glow plug circuits. They are not simplified; they show actual wire colors and connector positions.

How many pages is this manual?

133 pages of content, plus the index. The PDF is a direct scan of the original workshop manual binder.

If you plan to rebuild a Ford 1120, 1220, 1320, 1520, or 1720 tractor without a factory manual, you’re rolling the dice on every fastener. The torque values, bleeding sequences, and hydraulic test pressures are all inside this 133-page document. Access the Factory Manual and get the procedures that keep your tractor running and your knuckles intact.
