Ingersoll Rand 3016, 4016, 3018, 3020, 4018 Parts Catalog

If you’re tearing down an Ingersoll Rand compact tractor and you don’t have the factory parts catalog, you’re guessing. I’ve been wrenching for 28 years and I’ve seen what happens when a home mechanic tries to match a camshaft without a part number. You end up with the wrong piece, a wasted weekend, and a tractor that still won’t start. This is the Ingersoll Rand 3016, 4016, 3018, 3020, 4018 Parts Catalog – 67 pages of exploded diagrams, part numbers, and factory revision notes. It covers the Onan-powered machines: 3016 (before PIN 14147800), 4016 (before PIN 14149628), and all 3018, 3020, 4018 units. No aftermarket reprint – this is the document Ingersoll Rand sent to dealers.

Parts Catalog Coverage for 3016, 4016, 3018, 3020, 4018

Each model gets its own section keyed to the Product Identification Number (PIN) or serial number. The catalog uses those numbers to steer you to the correct revision of every component. The front index is alphabetical by major group – Engine, Fuel, Brake, Hydraulic System. The rear index is numerical by part number. You flip to the page, you see the exploded view, you read the reference number, and you write down the OEM part number. No cross-referencing third-party databases. Every illustration aligns the parts approximately as they sit on the machine. That matters when you’re trying to figure out which washer goes where on the steering gear.

What the Engine Section Actually Tells You

Inside the Engine group you get separate subsections for the starter, carburetor, exhaust pipes and covers, muffler and shields, oil base/pump/filter/filler tube, governor gearcase and ignition rotor, fuel system, air cleaner, and the piston/crankshaft/flywheel/camshaft assembly. Page 26 (approximate – you’ll find the exact page in the index) covers the cylinder block and blower housing. If you need to identify the crankshaft or camshaft, the catalog gives you the part number and the quantity required. For example, the camshaft on a 3016 with Onan P216G-I engine has its own reference number. That alone saves you a trip to the parts counter with the wrong casting in your hand.

Brake Assembly: Where Most Guys Screw Up

The Brake Assembly section lists every spring, shoe, and adjuster. I’ve seen backyard builders mix up left-hand and right-hand brake hardware. The catalog uses the standard RH/LH convention from the operator’s seat. The illustration shows the assembly exploded, and the parts list below gives the part number and required quantity. If a part is marked NSS (Not Sold Separately), it tells you it’s only available as part of an assembly. No guesswork – you order the assembly or you buy the part locally. That warning alone has saved me from ordering a part I couldn’t use.

Verify Your Part Numbers Against the Index

Before you call a supplier with a seven-digit number, use the numerical index at the back. It’s printed on the last pages of the 67-page document. Cross-check the part number against the page reference. If the number isn’t there, it’s either a superseded part or you misread the diagram. The catalog also includes footnotes tied to specific part numbers. Those notes might tell you about a design change or a special tool requirement. Ignore them and you’ll order the old version. The Paint and Oil section at the front gives the correct paint code and oil spec for the Onan engines. No, you cannot substitute a different viscosity and expect the governor to behave.

Fuel System: Diagrams That Save You Time

The Fuel System subsection covers the tank, lines, and carburetor connections. The Onan P216G-I, P218G-I, and P220G-I engines all use slightly different fuel fittings. The catalog shows the correct orientation of the fuel line clamps and the part numbers for the gaskets. If you’re chasing a lean condition, you can trace the entire fuel path from the tank to the carburetor inlet. The exploded view includes the fuel filter and the mounting bracket. You order the part, you install it, you move on. No guessing which filter cross-references – you have the Ingersoll Rand number.

Why OEM Documentation Beats Aftermarket Reprints

Aftermarket catalogs often combine multiple model years into one diagram and leave out footnotes about revision levels. This is the original Ingersoll Rand publication. It includes the revision notice instructions: as the product changes, new pages are released. A note in the front matter tells you to put all revisions into the catalog immediately. Aftermarket reprints skip that note. If you’re working on a 4016 that has had a mid-life update, the aftermarket diagram might show the wrong fuel pump. This catalog uses the PIN break points (e.g., 3016 before PIN 14147800) so you get the exact parts for your machine. That’s the difference between a one-hour repair and a week of return shipping.
