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

If you are ordering parts for an Ingersoll Rand compact tractor with an Onan engine and do not have the original factory parts catalog, you are guessing. That costs time, money, and customers.

I have been turning wrenches for 28 years, and I can tell you that aftermarket part cross-reference sites are a liability. This is the real thing: a 73-page OEM Ingersoll Rand 4016, 3016PS, 3018PS, 3020PS, 4016PS Parts Catalog. It comes straight from Ingersoll Rand, not some copy shop. Every exploded diagram, every part number, every “NSS” or “UAR” notation comes from the same source the dealer uses.

In the Automotive Industry Overview, OEM documentation is the standard for a reason – because incorrect parts mean lost billable hours.

73 Pages of Genuine Part Numbers

This catalog is exactly what it says: a parts catalog. Do not expect step-by-step repair procedures. Expect accurate part numbers, quantities, and assembly relationships. The index at the front and rear lets you find parts alphabetically or by part number. Page 2 lists the engine model for each tractor: 3016PS, 4016PS, and 4016 use Onan P216G-I; 3018PS and 4018PS use Onan P218G-I or Linamar LX770; 4020PS uses Onan P220G-I or Linamar LX790. Page 3 explains how to read the catalog – indented descriptions for assemblies, “NSS” for components only available as part of an assembly, “O/L” for local purchase.

Engine and Fuel System Breakdown

The ENGINE section is broken into subassemblies: AIR CLEANER, BLOWER HOUSING AND GOVERNOR, CYLINDER BLOCK, EXHAUST PIPES AND COVERS, FUEL SYSTEM, GOVERNOR GEARCASE AND IGNITION ROTOR, OIL BASE, PUMP, FILTER AND FILLER TUBE, PISTON, CRANKSHAFT, FLYWHEEL AND CAMSHAFT, MUFFLER AND SHIELDS, STARTER. If you need a piston ring set for a 4016, you find the reference number, part number, and quantity right there. No guesswork. The fuel system section includes the carburetor, fuel lines, and tank components – every fitting and gasket in exploded view.

Get the Right Brake and Hydraulic Components

The TRACTOR section includes BRAKE ASSEMBLY, CHOKE AND THROTTLE, ELECTRIC CLUTCH, FRONT AXLE, FRAME, FOOT PADS AND BELLY PAN, HOOD AND GRILLE, SEAT, FENDERS AND TOOL TRAY, MANUAL STEERING, TRANSMISSION AND FINAL DRIVE, SPEED CONTROL, ELECTRICAL SYSTEM AND HARDWARE, DECALS, and HYDRAULICS. The hydraulics subsection covers 4016 and PS tractors separately, with pump mounting components, power steering, drive motor, control valve, and hydraulic lift. Do not mix up parts between models – the catalog has separate pages for each. For the brake assembly, you get the brake bands, springs, and linkages illustrated with part numbers.

Hydraulics: Pump, Drive Motor, and Control Valve Details

For the PS tractors (3016PS, 3018PS, 3020PS, 4016PS) the hydraulic system is unique. The PUMP section lists pump mounting components. The POWER STEERING section shows the steering motor and hoses. The DRIVE MOTOR section covers the wheel motor assembly. The CONTROL VALVE and HYDRAULIC LIFT sections give you every seal, fitting, and bracket. If a hydraulic line leaks, you order the exact O-ring by number from this catalog. The 4016 non-PS models have a separate simpler hydraulic layout – also covered.

Does This Catalog Cover the Tractor Chassis and Steering?

Yes. Look under TRACTOR > MANUAL STEERING. Also FRONT AXLE, FRAME, FOOT PADS AND BELLY PAN, HOOD AND GRILLE. The BRAKE ASSEMBLY section includes brake bands, springs, and linkages. Every part that bolts onto the frame is illustrated with a corresponding parts list. For steering, you get the steering wheel, shaft, gearbox, and tie rods – all with OEM part numbers. This is the only way to guarantee you get the correct steering column bushing or brake pedal return spring.

FAQ – Parts Catalog for Ingersoll Rand Compact Tractors

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. You need the service manual for torque specs and repair procedures.

Can I use this catalog for serial numbers outside the listed range?

The catalog covers 4016 SN 14149628 to 14170800 and PS tractors likely similar ranges. If your serial number falls outside, parts may have changed. Ingersoll Rand issued revision pages. This catalog is a snapshot. You should verify with your dealer or look for newer catalog editions. However, many mechanical parts – especially engine internals and hydraulic components – remained consistent across years. Cross-check with engine model and spec number cited on page 2. If the engine model matches, most engine parts will be correct. Tractor-specific components like steering or hydraulics may differ. I always recommend ordering one part at a time if you are unsure, and compare the old part with the illustration.

Are the diagrams clear enough for a home mechanic?

Yes. They are line drawings with reference numbers keyed to parts lists. Each part is labeled with dimensions where needed. Experienced DIYers will find them usable. Beginners should take time to study the index and indented format on page 3.

How do I order parts using this catalog?

Have your model and PIN ready. Open the catalog, find the group (Engine or Tractor), locate the illustration, note the reference number, then find the part number in the list. Include correct part number, description, quantity, model, and PIN when ordering. Follow the instructions on page 3. Keep the order reference for future tracking.

When you have a customer waiting for a hydraulic hose and you need the right fitting, this catalog pays for itself in one order. Do not rely on memory or aftermarket lists. Download the Factory Manual from AutoRepairManuals and keep it on your shop computer.
