Ingersoll Rand 1112 Parts Catalog

You need a parts catalog for the Ingersoll Rand 1112. You need exploded diagrams that match the hardware on your bench. This Ingersoll Rand 1112 Parts Catalog is a 22-page factory-printed document from the OEM – not a reprint from some third party that lost resolution on the fasteners. Page 1 gives you the full alphabetical index. Page 2 explains how to read the reference numbers and part number columns. That’s the kind of clarity that stops you from ordering the wrong lockwasher.

What This 22-Page Parts Catalog Covers

The Tractor Section starts on page 5 with Chassis And Hood. From there you get Customer Assembly, Decals, Electrical Assembly (page 23), Engine and Control Assembly (page 17), Hitch Assembly, Motion Drive Assembly, Mower Suspension Assembly (page 9), Pre-Fitting Deck, Steering, Transaxle. The Engine Section begins at page 31 with the block, then carburetor, crankshaft, cylinderhead and stator, governor, oil filler, shifter. Every part has a reference number, a part number, and a required quantity. You get exploded illustrations that show exactly how the fasteners and brackets fit. This is not a guess-your-way-through diagram.

Electrical Assembly: Page 23 Details

Page 23 covers the Electrical Assembly. This includes the wiring, switches, connectors, and related components for the 1112 tractor. If you are chasing a no-start or a dead circuit, this page gives you the factory layout. Compare that to a generic wiring diagram that might use the wrong wire gauge or omit the ground path. The factory print shows you the exact part numbers for the ignition switch, solenoid, and harness clips. Order the correct parts the first time.

Engine and Suspension: Critical Sections for the 1112

The Suspension is covered under Mower Suspension Assembly on page 9. That’s where you find the deck hangers, belts, and spring hardware. The Engine section from page 31 onward breaks down the block, carburetor, crankshaft, and cylinderhead. If you are rebuilding the engine or replacing a blown head gasket, you need to know the correct part numbers for the pistons, rings, and valves. This catalog has them. No generic substitutions.

3 Reasons to Trust This Factory Parts Catalog

First, it’s from Ingersoll Rand. Not an aftermarket company that re-scans and reprints until the bolt heads are blurry. Second, the index is alphabetical and numerical – you can look up a part by name or by part number. Third, the exploded diagrams are grouped by assembly, so you see the relationship between parts. That saves you from ordering a part that doesn’t mate with the bracket you have.

The rear index lists every part number and the page it appears on. That alone is worth the price of the PDF.

OEM Print vs Aftermarket: Why It Matters

I’ve seen techs waste an hour on a carburetor rebuild because the aftermarket drawing swapped two screws. This catalog uses the same engineering drawings Ingersoll Rand shipped to dealers. The lockwashers, spring tensions, and stud lengths are all factory-specified. If you are working on a 1112, this is the only parts list you should trust. Aftermarket catalogs often skip the “O/L” (obtain locally) notes and “NES” (not sold separately) designations. Those details matter when you are ordering a governor spring that only comes with the assembly.

Frequently Asked Questions

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. It lists part numbers and quantities, not torque values.

How do I find the part number for the engine block?

Go to the Engine Section starting on page 31. The block is listed with its part number and reference number. Use the alphabetical index at the front to find ‘Block, Engine’ then flip to the listed page. The illustration shows the block with bolts, studs, and brackets. The part number is in the column next to the reference number. If you need a specific variant (e.g., short block vs long block), check the description. The catalog uses indented listings for components that are part of an assembly – if the block is only sold as part of an assembly, it will be noted as ‘NES’ (not sold separately).
