Ingersoll Rand 3118D, 4118D Parts Catalog

You ever order a part from a generic list, get it in the mail, and find out it doesn’t fit because the serial number range was wrong? I’ve seen that waste a whole afternoon. When you’re wrenching on an Ingersoll Rand 3118D, 4118D Parts Catalog compact tractor, the last thing you need is guesswork on which cylinder head gasket or fuel injection pump matches your machine. This is the factory Parts Catalog — not some third-party rehash. It’s the book Ingersoll Rand put together so dealers and mechanics could order the right part the first time.

Engine Section Breakdown: From Cylinder Block to Exhaust System

Flip to the ENGINE SECTION and you’ll find every major assembly laid out with reference numbers. The illustration for the cylinder block is on page 5, and the cylinder head with rocker shaft and valves is on page 9. Each part has a factory part number, description, and quantity. Need the alternator? Page 35. Fuel atomizer? Page 23. This is how you confirm you’re ordering the correct injector nozzle instead of something that dribbles fuel and knocks. The Engine section covers camshaft, timing gear, flywheel, connecting rod, piston, oil pump, water pump, thermostat, fan, and the entire fuel system — injection pump, fuel pump, and shut-off solenoid. No aftermarket catalog gives you that level of original indexing.

What Makes an OEM Parts Catalog Better Than Aftermarket Lists?

Aftermarket parts lists often skip serial number breaks. This manual prints the tractor model and PIN or serial number locations right on page 2. It tells you where to find the engine model and spec numbers — by the fuel injection pump. You match your unit’s S/N to the index and pull the correct part number. Miss that step with a generic list and you’ll order a radiator that doesn’t bolt up. The catalog also includes footnotes for part number changes, NSS (Not Sold Separately) notes, and UAR (Use As Required) quantities. That’s the kind of detail you only get from an OEM source.

Verify Part Numbers Against Your Serial Number

Before you call your supplier, open this catalog and cross-reference your tractor’s PIN. The MAIN ALPHABETICAL INDEX lists every component from Axle to Drawbar to Speed Control. Every part number in the book is tied to an illustration and a list on the facing page. You get the exact factory quantity — if it says 4, don’t order 6. And if a part is only available as an assembly, the indented description tells you. The manual even explains right-hand/left-hand orientation based on the operator’s seat. That prevents ordering a left-hand brake pedal when you needed the right.

Paint & Oil: Specifications You Cannot Ignore

The catalog includes paint codes (Power Red Gloss, Power White, Power Yellow, etc.) and hydraulic oil specs. It lists 20W40 for temperatures 32°F and above, 5W20 for below 32. That’s not a suggestion — that’s the factory spec for the hydraulic system. Use the wrong viscosity and you’ll lose lift capacity on cold mornings. The paint section gives you the exact color names and gloss levels so a repainted fender matches the original. No chasing after “close enough” rattle cans.

73 Pages of Factory Indexed Parts Data

73 pages cover everything from the exhaust muffler to the decals on page 71. The front index is alphabetical by major group; the rear index is numerical by part number. Each revision notice is meant to be inserted as the product changes. That’s how you keep a parts catalog current — by adding factory revisions, not reprinting from a scanned PDF that’s been out of date for years. If you do any disassembly on a 3118D or 4118D, this catalog is what the parts counter guy uses when you give him a serial number.

Frequently Asked Questions

Does this parts catalog include repair procedures?

No. It’s strictly a parts identification and ordering document. You get illustrations, part numbers, quantities, and serial number breaks, but no step-by-step disassembly instructions.

How do I know which revision or printing I need?

Check the serial number on your tractor’s PIN plate. The catalog refers to serial number ranges in the index. If your machine falls outside those ranges, you may need a later supplement. This edition covers both 3118D and 4118D models, but always verify against your S/N before ordering parts.

Can I use this catalog for a different Ingersoll-Rand model?

No. This catalog is specific to the 3118D and 4118D compact tractors with diesel engines. Other models like the 6000 series or T-708H require their own parts catalogs. The part numbers, paint codes, and torque references will not cross over.

What is the difference between this OEM catalog and a generic parts list?

This catalog contains original factory illustrations indexed by reference number, with part numbers that trace back to Ingersoll Rand’s own inventory system. Generic lists often transpose numbers or omit the NSS and UAR indicators, leading to wrong parts. You also get the official paint codes and oil viscosity specs — data that aftermarket sources frequently get wrong.

Every time I pull a part number from a factory catalog like this, I know it’s going to match. No returns, no cross-ref headaches. If you’re maintaining a 3118D or 4118D, stop flipping through blurry scanned knockoffs. Access the Factory Manual — it’s the same one Ingersoll Rand issued to dealers, with all 73 pages of original content.
