Ingersoll Rand 112B, 114B, 116B Parts Catalog

If you have ever ordered a throttle linkage for a 114B and got the wrong one because the aftermarket catalog had the drawing flipped, you know why I am writing this. I am Mike Callahan, 28 years turning wrenches in San Antonio, and I have watched guys waste a Saturday staring at a mislabeled part diagram. This Ingersoll Rand 112B, 114B, 116B Parts Catalog from the factory is the cure. 33 pages, no reprints, no copy of a copy – straight OEM documentation printed from the original file. The tractor models covered: 112B, 114B, 116B. If you touch one of these compact tractors, this catalog belongs on your bench.

Engine Section: What the 33 Pages Cover

Open to page 2 and you will find the paint and oil specs – gloss power red, semi-gloss black, 5W20 and SAE30 part numbers. That alone will save you from buying the wrong touch-up can at the parts store. The real meat is the ALPHABETICAL INDEX at the front. Engine section starts on pages 5-7 and covers the cylinder block, cylinder head, valves, camshaft, crankshaft, connecting rod, piston, oil pan, and gasket kits. Each part has a reference number linked to an exploded illustration. The grid references (A8-A10, B2-B6) tell you exactly where to look. I have seen techs try to cross-reference aftermarket diagrams and end up ordering a piston for a different stroke. This catalog kills that waste.

Camshaft, Crankshaft, and Cylinder – Exploded Views That Work

The camshaft entry on pages 5-7 shows the part in the same orientation as it sits in the block. Crankshaft, cylinder, connecting rod – all listed with their specific part numbers. For the 114B and 116B, the choke linkage is on page 11 with a separate reference (A14). The carburetor section (pages 13-15) includes the manifold for the 114B and 116B. If you need the breather filter, it is on page 21 next to the crankcase breather. No flipping back and forth guessing. The index is printed at both front and rear – see page 3 of the catalog. I like that. Reduces thumb wear.

Electrical System: When the Wires Don’t Match

Electrical system is listed under both the ENGINE SECTION and BASIC TRACTOR SECTION. In the engine section, you get magneto armature, spark plug, trigger ignition, starter, and battery on pages 9 and 53-55. The battery references D14-E2 grid. The starter is on page 51. For a machine that sits all winter, the trigger ignition part number (page 9) is worth having when the spark disappears. I have had three calls this year from guys who replaced the whole ignition module because they could not tell if the trigger or armature was bad. This catalog gives you the part numbers in the same document as the illustration – no flipping between two browser tabs.

Why a Factory Parts Catalog Beats Aftermarket

Aftermarket parts catalogs for compact tractors often combine multiple model years into one generic drawing. The OEM manual for the 112B, 114B, and 116B is specific. The PRODUCT IDENTIFICATION NUMBERS on page 2 list the exact engine model and spec for each tractor: 112B uses C30146 with spec 281707-0135-01; 114B uses C29099 with spec 400707-0119; 116B uses C29100 with spec 402707-0145. That level of detail is missing from third-party reprints. I have seen catalogs that claim to cover the 116B but use the wrong oil pan gasket because they copied from the 112B page. This factory document uses the same part numbering system Ingersoll Rand used when the tractor was built. If you work on Automotive Industry Overview equipment, you understand why OEM sourcing matters.

Who Uses This Catalog: From Novice to Seasoned Tech

If you are a home garage mechanic with a 114B that won’t start, the alphabetical index gets you to the fuel system (page 11) or electrical system fast. If you are a shop that sees a 116B every other month, having the rear numerical index saves time on part number lookups. The notes on page 3 explain UAR (use as required) and NSS (not sold separately) – that keeps you from ordering a part that only comes as an assembly. The paint and oil pages at the front are a bonus for restoration guys. I have used this catalog to track down a flywheel for a 112B that the local dealer said was discontinued – the part number was right there on page 9. Cross-reference the number and you can source it used or NOS.

A quick note on related manuals: if you work on larger Ingersoll Rand equipment, check the Ingersoll-rand T-708H 2000 Parts Catalog – Factory Specs or the Ingersoll-rand RT-706H, RT-708H 2004 Parts Catalog | OEM Factory Manual. For compactors, the Ingersoll-Rand SD 70 SD 77TF Parts Catalog: 352-Page Factory Manual covers a different class of machine but with the same level of detail. The Automotive Industry Overview context applies here – the same logic of factory documentation carries across all powered equipment.

Does this catalog include torque specs for the cylinder head?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views. Torque values are in the factory service manual.

Can I use this to order parts for a 112B with a different engine spec than listed?

The catalog lists the exact engine model for each tractor: 112B uses C30146, 114B uses C29099, 116B uses C29100. If your tractor has a different spec number, cross-check the engine model first. Use the serial number references on page 2 as a guide. If in doubt, call Ingersoll Rand with your PIN.

How do I read the grid references like B14?

Look at the illustration page. The grid is printed along the edges. B14 is the intersection of column B and row 14. Each part number corresponds to one grid location. Page 3 explains the illustration layout in detail.

Are decals included in this catalog?

Yes. Decals are listed on page 59 in the BASIC TRACTOR SECTION under the E6 grid. Part numbers for power red and black paint touch-up are also on page 2.

You have 33 pages of factory Ingersoll Rand documentation. The grid system, the dual index, the exact part numbers for engine, camshaft, crankshaft, cylinder, and electrical – all verified against the original OEM file. Access the Factory Manual and put it on your tablet or print it out. Either way, you are working from the same information the dealer’s parts counter uses.
