Cummins Onan P216G, P218G, P220G, OL16, OL18 2010 Parts Catalog

If you’ve ever ordered a carburetor gasket for a P220G and ended up with one that fits a completely different spec, you know the frustration. That’s the difference between a factory parts catalog and a generic parts list. This 2010 Cummins Onan P216G, P218G, P220G, OL16, OL18 2010 Parts Catalog gives you the exact part numbers and exploded views the factory uses. No guesswork when you’re inside a block.

85 Pages of Factory Parts Breakdown

Page 1 lists every model this catalog covers: P216G (Spec A-H), P218G (Spec A-H), P220G (Spec A-H), OL16 (Spec A-H), OL18 (Spec A-H), plus OL20, LX720, LX770, LX790. The whole horizontal Performer engine family. Each section groups parts by functional system — Adapter, Governor, Fuel System, Exhaust, you name it. You flip to the group, find the reference number, and order exactly what the factory intended. 85 pages of that kind of detail.

Valve Train and Cylinder Head Components

Need a valve cover gasket or a valve baffle? The catalog pages for “Baffle, Valve − Breather” and “Cap, Valve” are right there. The cylinder block section includes bearings, camshaft, crankshaft parts. Every valve-related component is called out with an illustration and a part number. No more matching old gaskets to third-party drawings that are off by 2 mm.

Fuel System Coverage: Gasoline and LP

Two complete sub-sections: Fuel System − Gasoline (starts around page 25) and Fuel System − LP Gas (page 29). Includes carburetor components for both gasoline and LP, auto choke versions, remote choke brackets — even the brass elbows for LP converter kits. Page 2 reminds you about safety warnings for gasoline and benzene. If you’re converting a P218G to LP or rebuilding the carb, this is the source document.

Does This Parts Catalog Cover Torque Specs?

No. This is a parts catalog, not a service manual. You won’t find torque values for head bolts or connecting rods here. But without the correct part numbers, torque specs on the wrong bolt are useless. Use this catalog to order the right fasteners, then grab the factory service manual for tightening sequences. For generator-specific manuals, see Cummins Onan RBAB 6kW-15kW 2013 Operators Manual | OEM Factory Specs.

OEM Authenticity vs. Aftermarket Reprints

The document you get from AutoRepairManuals is the original 2010 Onan publication — 965-0268 (Issue 8). Page 2 shows the actual hazard symbols and safety messages from the factory. Aftermarket reprints often miss the margin notes, the sales code definitions, or the fine print on cancer warnings. If you’re working on a marine critical part (like on an OL18 generator), the manual explicitly says servicing must be done by trained personnel. That warning disappears in a copy.

Starter and Electrical Components: Factory Diagrams

Starter components are broken down into three pages: Components, Starter (page 19, 20, 21). You get the clutch assembly, drive gear, end caps, and solenoid caps all illustrated. The ignition control, alternator, and flywheel sections are equally detailed. For background on engine electrical theory, see this Wikipedia article on diesel engines — though these are gasoline/LP, the ignition principles overlap.

If you’re rebuilding a Performer horizontal engine or just need a specific washer, this is the document that removes the parts counter lottery. Futura FC200-FC400 Parts Catalog – OEM Wear Parts Specs is another example of factory-level detail. Access the Factory Manual from AutoRepairManuals and keep your rebuild on schedule.

Does this manual list torque specifications for head bolts?

No. This is a parts catalog, not a service manual. Use the factory service manual for torque values.

Can I use this catalog to order parts for my OL16 generator engine?

Yes. The OL16 (Spec A-H) is listed on page 1. The catalog uses the same part numbering system as other Cummins Onan engines. Cross-reference the spec number from your nameplate. The safety section on page 2 reminds you to always provide model, spec, and serial numbers when ordering. This catalog groups parts by functional system—fuel, ignition, cooling, etc.—so you can find the exact component. Pay attention to the “Sales Codes (Definitions)” on page 75 for any special variants.
