Dynapac CP142 Parts Catalog

If you’re keeping a Dynapac CP142 pneumatic roller running in a Texas yard or a job site, you already know the pain of guessing part numbers. I’ve spent years under heavy equipment, and nothing burns time faster than ordering the wrong filter or bushing because the aftermarket book shows a generic cross-reference. This Parts Catalog is the OEM factory book from Dynapac – printed for serial number range starting *10000500V0B001385*. It’s the same document the dealer uses when they quote you a price.

Covers the CP142 Tier3 with Cummins QSB 3.3 diesel engine. 112 pages of exploded-view line drawings, part numbers, and ordering codes. No reprints, no photocopies – direct PDF scan of the original SCP142-2EN1 catalogue issue dated 2011-04. You get the same six-language order instructions on page 2 that tell you exactly what data to provide: type, serial, quantity, part number, denomination, and dimensions. Miss that step and you’ll be staring at the wrong box when it arrives.

I keep a copy on my shop tablet. When a scraper blade or sprinkler nozzle goes bad, I pull up the diagram, read the part number aloud over the phone, and the supplier knows exactly what I’m talking about. That’s the difference between OEM and third-party garbage.

Service Kits: Scheduled Maintenance Intervals

Three distinct service kits are listed for the Cummins engine: 50-hour (4812155996), 250-hour/750-hour (4700939076), 500-hour (4700950175), and 1000-hour (4812155997). Each kit groups the filters, seals, and wear items you need for that interval. Suspension components are covered separately – front suspension, rear suspension, and wheel assemblies all have their own exploded views. If you’re doing a 500-hour service, grab the kit, then check the suspension bushings while the roller is on jackstands.

Where Do You Find the Frame and Ballast Parts?

Frame section is split into Frame and Ballast, Hood and Covers, Scrapers and Mat, and Sprinkler System – either one-pump or two-pump configuration. The diagrams show fasteners, brackets, and ballast weights with exact part numbers. No guessing which bolt goes where. Torque specs aren’t in this catalog (that’s in the service manual), but the parts breakdown is accurate enough to order replacements without pulling a .pdf off some shady forum.

3 Major Suspension Sections

The catalog dedicates a full group to Suspension: Front suspension, Rear Suspension, and Wheel. Each page shows the rubber isolators, bushings, and steering knuckles with callouts. If you’ve got a vibration issue on the roller, check the rear suspension mounts first – that’s a common wear point on CP142s. With this manual, you can match the shape and hole pattern from the diagram to what’s on your machine. Works better than trying to describe it over the phone.

Understand the Hydraulic System Layout

Hydraulic system group covers Propulsion system, Hydraulic oil tank, Hydraulic filters, Drain system, Speed system, and Hydraulic steering. Each subsystem has its own parts list. The propulsion circuit uses a specific pump and motor – the catalog gives you the exact replacement unit part number. Ordering a hydraulic filter? The part number is right there next to the illustration. No need to decode a reference manual.

Electrical Equipment: Driving and Working Lights

Two subsections: Driving lights and Working lights. Bulb types, housings, and connectors are all listed. If a light goes out mid-shift, you can pull the part number from the catalog and have the replacement delivered before end of day. Also covers the main electrical equipment – alternator, starter, fuses. The diagrams are crisp enough to trace wiring harness connectors.

Audience Fit: Who Needs This Catalog

If you own or operate a CP142 pneumatic roller and do your own maintenance, this is your parts bible. Home garage guys who also run construction equipment will appreciate the exploded views – they make finding the right part on a messy workbench possible. Shop foremen can hand this PDF to a junior tech and say “find the part number for the front suspension bushing” – it’s a teaching tool. Beginners should not rely on it for repair steps, but for ordering parts it’s gold.

A real-world use: Your CP142’s sprinkler system starts leaking from the pump. You open the catalog, flip to the Sprinkler system section (one pump version or two pump – verify from your machine), identify the pump in the drawing, and jot down the part number. One phone call to the dealer and the pump is on its way. That’s what I mean by saving billable hours.

Source Validity: OEM vs Aftermarket

This is a genuine Dynapac factory publication, part number SCP142-2EN1, printed in Sweden. The OCR excerpt on page 1 carries the Dynapac logo and the Atlas Copco Group branding. Page 2 shows the ordering instructions in six languages – that’s the kind of detail aftermarket knock-offs strip out. Aftermarket catalogs often re-draw diagrams and misalign callouts. I’ve seen a ‘universal’ parts book that listed the wrong hydraulic filter for a CP142, cost a guy an entire afternoon waiting for the right one. With the OEM catalog, you get the same illustrations Dynapac dealerships use. That matters when the roller is down and you need parts fast.

One more thing: the serial number coverage. This catalog is valid from serial *10000500V0B001385* and later. If your machine is older, double-check because some early CP142s had different frames. That warning is printed right on page 1. Always verify the serial range before ordering.

FAQ: Four Common Questions

Does this Parts Catalog include service procedures or torque specs?

No. This is strictly a parts identification document with exploded diagrams and part numbers. For repair procedures, you need the Dynapac CP142 Service Repair Manual.

How do I find a specific part number for the hydraulic steering?

Open the Hydraulic system group, then find Hydraulic steering. The diagram shows each component with a callout number. Match it to the list below the drawing. That’s the part number.

Is this the same catalog used by Dynapac dealers?

Yes. It’s the OEM SCP142-2EN1 publication. Dealers use this exact document to order parts from Dynapac.

Can I use this on a tablet in the field?

The PDF is text-searchable and works on any device that opens PDFs. I run it on a 10-inch tablet inside a waterproof case. Works fine.
