John Deere 110, 112 1967 Service Manual

You’ve got a 110 or 112 that won’t start, or the engine is knocking, and some PDF from a third-party site tells you “torque to spec” but doesn’t even list the thread pitch. That’s not a manual. That’s a waste of ink. This is the real deal – the John Deere 110, 112 1967 Service Manual, printed April 1967, SM-2059, 310 pages from the Horicon Works. Page 1 tells you exactly what you’re holding: official Deere documentation. Page 2 lays out every section – from the Kohler engine in the 110 to the Tecumseh in the 112, fuel system, electrical, power train, hydraulics. No guesswork. No fluff. Just the specs your grandfather’s tractor deserves.

Engine Overhaul: Kohler and Tecumseh Coverage

Section 20 is where you’ll live if you’re tearing down an engine. For the 110, it’s the Kohler – groups cover Cylinder Head, Valves and Breather, Piston, Crankshaft, Main Bearings and Flywheel, then Camshaft, Tappets and Governor. For the 112, same structure but for the Tecumseh. The crankshaft main journal clearance? Page at the end of each group gives you the factory wear limits. I’ve seen too many backyard rebuilds fail because they guessed the end play. This manual doesn’t let you guess. Cylinder head bolt torque sequence is laid out with a diagram – not just a number. Follow it.

Fuel System: From Carburetor to Gas Tank

Section 30 – Fuel System – is five groups: General, Carburetor, Air Cleaner, Sediment Bowl, Fuel Strainer and Gas Tank. If your 112 is sputtering, you don’t replace parts. You diagnose. The manual lists possible troubles, causes, and corrections. For the carburetor, it shows the float setting and needle valve specs. The sediment bowl cleaning procedure is on a dedicated page. Fuel system problems are a pain on these old tractors because ethanol eats the rubber. But the OEM manual tells you the original fuel line ID and the correct replacement part numbers. Use that data, not a parts store cross-reference.

What Torque Values Are Listed?

Every group ends with a Specifications page. You get torque for cylinder head bolts, connecting rod nuts, flywheel retaining nut, and axle bearings. These are not “hand tight” numbers – they’re inch-pounds and foot-pounds from Deere’s own test lab. For example, the Kohler cylinder head torque is listed in Group 10 of Section 20. If you’re reassembling a variable speed drive (Section 50, Group 10), the clutch and brake clearances are given. Ignition timing for the Kohler K301? Group 10 of Section 40. I’ve had guys strip threads because they used a Chilton’s chart. Don’t be that guy.

3 Reasons OEM Documentation Beats Aftermarket Reprints

First, the source. This manual was printed by John Deere in April 1967 for tractors up to serial number 100,000. Every spec – from the 3-speed transaxle to the hydraulic cylinder – was verified against production parts. Aftermarket reprints often skip pages or blur wiring diagrams. Second, the diagnostic logic. The manual emphasizes analyzing malfunctions instead of swapping parts. Third, safety. Section 50’s clutch/brake adjustment procedure includes warnings about driveline lock-up. You don’t get that in a generic “repair guide.”

Real-World Use Case: Restoring a 112 with a Stale Fuel Problem

A guy in my shop brought in a 112 that hadn’t run since 1985. The aftermarket manual said “clean the carburetor.” This OEM manual walks through the sediment bowl removal, fuel strainer cleaning, and carburetor disassembly with the exact jet sizes. The float level – 0.250 inches – is on page 3 of Group 10. I had a 110 with a stuck governor; the camshaft tappet adjustment procedure in Group 20 of Section 20 saved me an hour of head-scratching. Whether you’re in a home garage or a 6-bay shop, this manual pays for itself on one job.

Serial Number -100,000: Why That Matters

The cover says “(Serial No. -100,000)”. That means this manual applies only to tractors built before a certain production break. If yours is 100,001 and later, you need the supplement. This level of specificity is what makes OEM documentation worth the paper. Third-party manuals slap “fits all models” on the cover and leave you guessing. Here, every procedure is tied to a serial range. The engine section even separates Kohler and Tecumseh by group – no mixing up parts. I keep a binder of these for the shop because when a customer says “my 110 is a 1967,” I hand them this manual and know the data matches.

Power train coverage includes both the 3-speed Manual Transmission”>Manual Transmission (Group 15 of Section 50) and the 4-speed Manual Transmission”>Manual Transmission (Group 20). Each has its own gear ratios, shifter fork clearances, and differential specs. Section 60 covers the hydraulic system – control valve, pump, and cylinder – with relief pressure settings. Section 70 handles steering linkage and front axle.

Does this manual cover the 110 with Kohler engine?

Yes. Section 20, Groups 5 through 20 are specifically for the Kohler engine used in the 110 tractor.

Are the wiring diagrams in color?

The original manual is black-and-white line art. That’s fine because the schematics use clear labels and trace paths. I’ve worked from these diagrams for years on charging system repairs – they’re accurate enough to find a short without color. If you need color, you’re not reading the diagram.
