Dynapac CP142 Parts Catalog – OEM Factory Document for the CP142 Tier3 Roller

You ever order a part for a CP142, wait three days, and get the wrong damn thing because someone upstream used a generic cross-reference? I have. Wasted billable hours, had a customer chewing my ear off while his roller sat dead. That stops with the Dynapac CP142 Parts Catalog from the factory. This isn’t a reprint or a third-party hack-job – it’s the actual OEM document, 110 pages, covering serial number 2163BR3000 and up. Every part number, every diagram, every exploded view came straight from Dynapac. No guesswork.

Flip to any section – you’ll find exact part numbers, quantities, denominations. Need a service kit for the Cummins QSB 3.3 at 50 hours? That’s part number 4812100391. The 250-hour kit? 4812100392. Those numbers come from the Service kits chapter. I’ve had too many aftermarket catalogs give me a cross that doesn’t fit. This catalog removes that headache.

Service Kits: Cummins 50h and 250h

Two dedicated service kits are listed right in the Service kits section. The 50-hour kit (4812100391) and the 250-hour kit (4812100392) cover the Cummins engine. Each kit comes with its own bill of materials – gaskets, filters, seals – whatever Dynapac spec’d. If you’re a shop owner, you stock these numbers. If you’re a DIY mechanic, you order them once and know they’ll fit. The catalog breaks it down so you’re not hunting through a dozen pages. One section, two kits, done.

Frame and Ballast: Know Your Roller Structure

The Frame chapter covers more than just the main frame. You get Frame and Ballast, Hood and covers, Scrapers, and even Scrapers and mat. There are two sprinkler system variations – one with a single pump, one with two pumps. Why does that matter? Because if you’re replacing a sprinkler assembly, ordering the wrong configuration means a return trip. The catalog shows both setups with distinct part numbers. No ambiguity.

Suspension Breakdown

The Suspension section splits into Front suspension, Rear Suspension, and Wheel. That’s three sub-groups that cover every bushing, bearing, and mount on a CP142 front and rear. I’ve seen guys try to source generic suspension components – bad idea. The factory document gives you the exact Dynapac part numbers. If you’re rebuilding a front suspension on a CP142, you pull this catalog, find the exploded diagram, and order the correct hardware. No returns, no fitment drama.

Engine Module: Filters, Cooling, Fuel

Engine coverage runs deep. You’ll find Engine filters, Engine module (two entries – check the revision), Cooling system, Air cleaner, Fuel system, and Exhaust system. The air cleaner alone has its own sub-section with specific filter part numbers. The cooling system includes radiator and fan components. For a Cummins QSB 3.3, you need these numbers to be spot-on – one wrong filter and you’re chasing a restriction. The catalog lists them correctly.

Hydraulic System: Propulsion and Steering

Hydraulic system? It’s broken into Propulsion system, Hydraulic oil tank, Hydraulic filters, Drain system, Speed system, and Hydraulic steering. The propulsion group includes the pump and drive motor parts. The Speed system is separate – that’s for the roller’s travel speed control. If you’re rebuilding a steering cylinder or replacing a filter, the catalog gives you the part number and quantity. No need to guess which O-ring fits the tank drain – it’s listed in Drain system.

Electrical Equipment: Driving and Working Lights

Electrical equipment covers the main harness, Driving lights, and Working lights. The driving lights section lists the bulbs, lenses, and brackets. Working lights are separate – these are the flood lights for night operation. If a light goes out on a job site, you don’t want to waste time testing generic bulbs. Get the factory part number from this catalog and order it right.

Who Needs This Manual?

This catalog is for anyone who touches a CP142 – shop foremen, mobile techs, equipment dealers, even owner-operators who do their own maintenance. If you’re ordering parts for a CP142 Tier3 roller (serial 2163BR3000 or later), this is your reference. The Numerical index at the back lets you look up a part number fast. No flipping through pages randomly. You’ll find the Optional equipment section too – canopies, rotating beacons, tool kits. If your machine has options, the part numbers are there.

Why OEM Documentation Beats Aftermarket

Aftermarket parts catalogs are usually photocopies of photocopies, with smudged diagrams and missing part numbers. This Dynapac CP142 Parts Catalog is a clean PDF scan of the original factory publication. Every page is legible, every part number is machine-readable. You get Service kits, Frame, Suspension, Engine, Hydraulic system, Electrical equipment, Drivers platform, Decals, Standard equipment, and Optional equipment – all 110 pages of it. I trust aftermarket documentation about as far as I can throw a torque wrench. Stick with the factory source.

FAQ

Does this catalog include part numbers for the Cummins engine?

Yes. Engine section covers filters, module, cooling, air cleaner, fuel, and exhaust.

How do I order the correct sprinkler system parts for my CP142?

Check the Sprinkler system sub-group under Frame. The catalog lists two versions: one-pump and two-pump. Verify your machine’s configuration (look at the physical pump count) and match the part numbers. After that, check the Numerical index to confirm quantities – the catalog shows exploded diagrams for each variant so you can visually verify. If you order the one-pump part for a two-pump setup, you’ll be missing fittings. The factory diagrams prevent that mistake.
