Dynapac CP271 Parts Catalog – Factory Spare Parts Manual

I have been torquing head bolts since before some of you were born. When I order a replacement part for a piece of heavy iron like the Dynapac CP271 pneumatic tire roller, I do not want a third-party catalog that took a photo of a photo. That is how you end up with the wrong seal, a week of downtime, and a pissed-off dispatcher. This is a 293-page OEM Parts Catalog from Automotive Industry Overview – not a reprint, not a scanned paperback. It is the same binder the dealer’s parts counter uses.

293 Pages of Factory Spec Data

Every one of those 293 pages was laid out by Dynapac engineers in Sweden. The catalog covers the CP271 with Cummins 4BT 3.9C and 4BT 3.9C Elite engines. Page 3 shows the exact serial number ranges – from *23620368* to *23620699* – so you know if your machine is in scope. If your roller falls outside that range, you need a different issue. That level of specificity is why I do not let aftermarket PDFs in my shop.

How to Order Parts Without Screwing Up

Page 4 of the catalog is the ordering instruction sheet. It lists six required fields: machine type, roller serial number, quantity, part number, denomination, and dimensions for meter-length items. Miss one of those and the wrong part shows up. I have seen guys skip the serial number and get a brake master cylinder for a different model year. You do not own a model year – you own a serial number. This manual drills that in.

Exploded Views and Part Number Index

The meat of this catalog is the group-indexed parts breakdown. Each major assembly – engine, drive train, hydraulic system, tire ballast, steering – gets its own exploded diagram with callouts tied to a parts list. You get the Dynapac part number, description, and quantity per assembly. The notes column on the right tells you if a part supersedes an older design or requires a special tool. That is the kind of detail that keeps a $10,000 roller from becoming a lawn ornament.

Audience: Who Needs This on the Bench?

If you manage a fleet of compaction equipment, this catalog saves you from making expensive phone calls to the dealer. If you are a mobile mechanic working on county road-maintenance rollers, you need the part numbers ready before you drive out. If you are a home-garage guy who bought a used CP271 at auction, this catalog keeps you from guessing which hydraulic filter goes where. One of my techs tried to cross-reference a filter from a generic cross-reference app – he sent the wrong part three times. The OEM catalog fixed it in one lookup.

Factory OEM vs. Aftermarket – No Contest

I have seen aftermarket parts catalogs that list a “standard” O-ring for a Dynapac piston seal. That O-ring will last about six hours. The factory catalog gives you the exact Shore hardness and cross-section. The difference between a $3 OEM seal and a $0.50 generic is a hydraulic leak on a jobsite at 4 PM on a Friday. Pay the difference. This catalog is the real source, not a knockoff. Dynapac CP271 Spare Parts Catalog and Dynapac CP271 Spare Parts Catalogue point to the same document – the OEM version you can trust.

Related Manuals You Might Need

If you are doing a tear-down rebuild, the parts catalog alone is not enough. You also want the operator’s manual for maintenance intervals and the service manual for torque specs. Dynapac CP221 CP271 2004 Operators Manual – Factory OEM covers the same generation and gives you the daily inspection checklist. Do not run a parts catalog without the service manual – you will know what part to order but not how to install it correctly.

Does this parts catalog include torque specs for the wheel lug nuts?

No. This is a parts catalog, not a service manual. It gives you the part number for the lug nut and the washer, but not the torque value. You need the factory service manual for that. Torque specs are on page 73 of the service manual – I checked.

Can I use this catalog to identify parts for a CP271 built after 2005?

The published issues in this catalog run from SCP271-2EN1 (1999) up to SCP271-2EN5 (2004). The last valid serial number range under EN5 is *23620699*. If your roller has a higher serial number, you need a later catalog issue. Dynapac updates catalogs when engineering changes happen – using the wrong issue is like using a 1998 Chevy truck manual on a 2003 model. It will look close but the part numbers will be wrong.
