Case 1850K Parts Catalog

If you’re ordering parts for a Case 1850K crawler dozer, you already know that guessing gets expensive. This is the OEM Parts Catalog from Case, 703 pages of part numbers, quantities, and exploded views. Not a reprint, not a scanned copy from some third-party site. Factory-original documentation that shows you exactly what Case used on the assembly line. I’ve seen too many operators buy the wrong filter because a generic parts list showed a number that was close but not exact. That costs you a day of downtime and a return shipping fee. Don’t be that guy.

Filters Section: Part Numbers You Can Trust

Open the catalog and you’ll hit the filters section right away. Page 2 lists part numbers for oil filters, fuel filters, air filters – all with Case’s own reference numbers and quantities. For example, the fuel filter assembly uses part 1931148 (qty 1) and the element 1931147. Next to each number is a parenthetical (3.444) – that’s the list price code from the factory. If you’ve ever tried to cross-reference a filter with an aftermarket book, you know the headaches. This catalog kills that guesswork. The OEM number is the one that fits the housing, seals properly, and doesn’t leak. Period.

Version Identification: Matching Your Machine’s Engineering Code

The 1850K came in three track configurations: LT (low ground pressure), LGP (extra low ground pressure), and XLT (extra wide). Each has a different engineering code: 535.100.053, 535.100.054, 535.100.055. The catalog breaks down parts by these codes. You’ll find the model and product code on page 4. If you order a final drive seal for an LT and try to install it on an LGP, you’ll be making a second order. The catalog gives you the part number specific to your machine’s code. No guesswork.

Engine Model Variations: Cummins 6CTA8.3 Power Levels

This catalog covers both the 190HP and 215HP versions of the Cummins 6CTA8.3 engine used in the 1850K. The engineering code FR 91003 and FR 90895 are listed on page 4, along with the numerical codes 01, 02, 03. That means the engine parts – injectors, gaskets, turbo components – are split by horsepower rating. An aftermarket catalog might list one part for all engines, but Case knows the difference. You need the right piston kit for the 215HP variant? The catalog shows the correct part number under code 02. That’s the difference between a rebuild that lasts and a top-end failure at 500 hours.

Serial Number Location: Where to Find Engine and Machine Numbers

Before you order anything, you need your machine serial number. The catalog gives you the exact location on the dozer (page 4): for the 1850K LT it’s stamped on the frame near the left track frame, prefix HHA1850ST. Engine serial number is on the Cummins data plate, left side of the block. The catalog includes a blank table for you to record both numbers. Do that. I’ve had guys call me with a machine that’s been modified, and without the serial number, we’re guessing. The catalog is only as good as the data you feed it.

Why an OEM Parts Catalog Beats Aftermarket Lists

Aftermarket parts catalogs are often compiled from older editions, mixed with supersessions, and full of errors. This one is printed from Case’s own database. Every part number has been verified against the engineering release. The 703 pages cover the entire machine – undercarriage, drivetrain, hydraulics, electrical, cab, and attachments. You won’t find a missing section or a page that says “see dealer for details.” If you need a service manual with torque specs and procedures, grab the Case 1850K Crawler dozer Operator’s Manual or the CASE 1850K Series 3 Crawler Dozer Operator’s Manual – those have the tighten sequences. For parts, this is the only catalog you should trust. Also check the Case CX160B 2007 Parts Catalog – OEM Undercarriage Hydraulics if you work on excavators too. For a broader look at construction equipment documentation, the Automotive Industry Overview gives context on OEM standards. And Automotive Industry Overview touches on why factory specs matter for heavy equipment.

Does this catalog include service procedures?

No. It’s a parts catalog, not a service manual.

How do I know which part number fits my machine if I have a later serial number?

The catalog lists engineering codes and model series. You need to locate your machine serial number (page 4 shows location) and match it to the correct version. The catalog breaks down parts by model: LT, LGP, XLT. If your machine is a later production, check the version list. Aftermarket catalogs often lump all years together, but Case splits them by engineering code. That’s the difference between a bolt that fits and one that doesn’t.

Stop ordering parts by guesswork. This factory catalog gives you the exact numbers Case stamped on the parts. Get the right part, get the dozer back in the dirt. Access the Factory Manual.
