Ingersoll Rand 3118D, 4118D Parts Catalog

I have seen too many techs waste billable hours chasing part numbers that don’t match because they bought a third-party reprint. This Ingersoll Rand 3118D, 4118D Parts Catalog is the real thing – factory-original, 46 pages of exploded-view illustrations and exact part references. No guesswork about which alternator fits your 3118D or which oil pan gasket goes on the 4118D. The manual comes straight from Ingersoll Rand’s own press, and that makes a difference when you are staring at a disassembled compact tractor on the lift.

Parts Identification: Beyond the Part Number

Every illustration in this catalog pairs a reference number to a part number table right opposite the drawing. You get the quantity needed, plus footnotes that tell you when a part is NSS (not sold separately) or UAR (use as required). That “Obtain locally” (O/L) tag appears on common hardware, so you are not paying overnight shipping for a bolt you can get at the hardware store. On page 3, the general information section explains how to read the indented descriptions – critical when an assembly includes sub-components that are only sold as a unit. Miss that footnote, and you might order a whole hydraulic pump when you only needed a seal.

Engine Section Coverage: 7 Major Systems Listed

The alphabetical index splits the manual into engine and tractor sections. Under ENGINE SECTION you get 7 distinct groups: block, camshaft, carburetor, crankshaft, flywheel, piston, valves. Each group has its own page with exploded diagrams. For example, the cylinder head group (page 33) shows every valve, spring, and retainer. Need a glow plug? It is listed under Pump, Glow Plug in the fuel system section. The index is color-coded by ear index – quick reference for anyone who has used an OEM parts book before. No flipping through random pages trying to guess where the muffler lives; it is under Exhaust System on page 25.

Paint and Oil Specs: Factory-Listed Finishes

Page 2 of the catalog lists every paint color the factory used – black gloss, Power Red gloss, silver gloss, even heat-resistant semi-gloss for exhaust components. Part numbers are given for spray cans (12 oz) and touch-up bottles. That same page lists the correct oils: SAE 30 SF, SAE 5W/20, and SAE 20W/40. If you are restoring a 3118D or 4118D, this page keeps you from guessing which red is the right red. I have seen tractors painted with the wrong shade because a parts store matched a faded fender. The factory spec is right here.

Reading the Index: How to Find Any Part in Under 30 Seconds

The front and rear of the catalog each have an index. The ear index is alphabetical by major group – look up “Brake Assembly” and go to page 63. The model index is numerical, listing each part number and the page where it appears. Both are dead simple. If you are ordering parts over the phone, the person on the other end needs the correct part number, not a description. That is exactly why this catalog exists: to eliminate the “I think it’s the left-hand one” problem. Right-hand and left-hand are defined on page 3, so you do not end up ordering a mirror-image part.

Source Validity: OEM vs Aftermarket Reprints

This is a factory-original Ingersoll Rand publication, not a scanned-and-retyped knockoff. The part numbers tie directly to the current Ingersoll Rand supply chain. Aftermarket catalogs often renumber parts or omit superseded items. Here, every revision note tells you when a page has been updated. The manual includes the identification section that shows where to find the engine model and serial number on the 3118D and 4118D – that information is on the fuel injection pump. Without that, you might order parts for the wrong engine variant.

If you work on these compact tractors regularly, you need the companion service manual too. Check the Ingersoll 3118D 4118D Parts Catalog for the full service specs. For a different Ingersoll Rand machine, the Ingersoll Rand T-708H Tow Tractor Parts Manual 2000 covers towing equipment, and the Ingersoll-Rand RT-706H/708H Rough Terrain Forklift Parts Manual handles rough terrain lifts.

FAQ

Does this catalog include torque specifications for the 3118D or 4118D?

No. This is a parts catalog, not a service manual. It lists part numbers, quantities, and assembly relationships. For torque specs, you need the factory service manual.

How do I know if my tractor’s serial number matches the 3118D range covered by this catalog?

The product identification section (page 2) explains that the tractor model is on the chassis, and the engine model and serial number are stamped on the block near the fuel injection pump. Cross-reference that with the engine identification table that lists Ingersoll No. C42982 and Perkins H2.738A. If your engine matches, the catalog covers it. If not, you may need a different parts book. Always verify serial numbers before ordering – the footnote on selection cautions that part updates may apply only to certain serial number ranges.

If you spend your day wrenching on compact tractors, having the factory parts catalog means the difference between a 30-minute parts lookup and a two-hour wild goose chase. Access the Factory Manual and keep it on your shop tablet.
