Case 1150K Parts Catalog – What You Actually Get on the Bench

I’ve rebuilt more undercarriages than I care to count, and there’s one thing that grinds my gears: ordering the wrong part because some aftermarket parts guide blurred a reference number. If you’re working on a Case 1150K Series 3 crawler dozer, this Parts Catalog is the only document that tells you exactly which bolt, spacer, and seal goes where. 355 pages of OEM exploded-view drawings, not a reprint or a third-party compilation. You get the same illustrations the Case assembly line used.

Let me walk you through what’s inside this thing, so you know why I’d reach for it before I crack an aftermarket PDF. Any mechanic who’s swapped a radiator on a 1150K knows the mount bushings are specific. The catalog gives you the exact Case part numbers and even tells you which Loctite to use on the fan-to-spacer bolts – Loctite 243 per page 3 of the fan section. That’s the kind of detail that saves you a tow and a $400 hose because you grabbed the wrong one.

Fan and Belt Assembly: Detailed Breakdown

Flip to section 02-01. You’ll see the pusher fan (part A173018), the spacer (87363663), and the belt (87561763). The exploded view shows every screw and bolt with its grade – M10 x 90 socket head cap screws rated 8.8, hex flange bolts M8 x 30 at 10.9. And it tells you to apply Loctite 243. That’s not something you get from a chiltons or a random online listing. If your alternator belt slips because you reused a worn tensioner bracket, the catalog lists the belt as “Engine Fan and Alternator Belt, Main” – so you order exactly that, not a guess.

Radiator and Oil Cooler Mounting: What the Factory Drawings Show

Section 02-02 covers the radiator/oil cooler assembly and its mounting hardware. The cooler assembly itself is part 87379707. But the real value is the supporting parts: the rubber bushings (A59514), the straps (435979A1), the seals (87542265 – 770 mm adhesive back; 87347776 for the lower). Even the hose clamps have a size spec – 1.25/2.625 HD worm clamps (214-3140). If you’ve ever closed a hood only to find you left a hose clamp loose because you used a generic one that didn’t fit right, you know why the OEM part number matters. This catalog also tells you which hoses require Loctite 30525 Hi-Tack at the engine outlet. Skip that step and you’ll be chasing a coolant drip.

Does This Catalog Include Torque Data?

Not directly. This is a parts catalog, not a service manual. It lists bolt grades and thread-locker requirements, but you won’t find torque values here. For torque specs you need the factory service manual. However, the parts catalog shows you which fasteners are critical – for example, the M10 x 45 bolts (grade 10.9) that hold the radiator mount straps. If you were going to guess a torque on a 10.9 bolt, you’d probably be wrong. That’s why I pair this catalog with the CASE 1150K Series 3 Crawler Dozer Operator’s Manual for everyday checks, and the full service manual for rebuilds.

355 Pages of OEM Part Numbers

Every one of those 355 pages is a factory print. They didn’t crop out the reference numbers or resize the drawings. You get the original exploded views with leader lines pointing to each part, plus a table with description and quantity. No reprint artifacts, no blurry scans. The radiator mounting section alone shows 42 parts with callouts. That’s the level of detail you need when you’re rebuilding a 15-ton dozer in your shop and the parts counter guy asks for the number off the old spacer. You’ll find it in the catalog.

Source Authenticity: Why Case Factory Print Matters

I’ve lost count of how many aftermarket parts catalogs I’ve seen that substitute a similar-looking part number from a different model. That’s how you end up with a fan that has the wrong pitch or a spacer that’s 2 mm off. This document is an original Case publication. The part numbers match what Case dealers scan when you give them the model and serial number. If you want to read about why OEM documentation matters in the wider Automotive Industry Overview, feel free. But on the job site, you just need the right number. This catalog gives it.

How to Use the Exploded Views Effectively

Each section starts with a full-page exploded drawing. Find the part you need, note the reference number, then go to the facing table for part number, description, and quantity. For example, want the lower radiator seal? It’s item 21 in section 02-02 – 87347776. Write it down, order it. Simple. No guesswork. And if you notice a bolt that’s thread-locked in the drawing, you better use thread locker when you reassemble. The catalog won’t tell you why; it just shows the spec. That’s your responsibility.

If you’re also working on other Case machines, the Case CX160B 2007 Parts Catalog – OEM Undercarriage Hydraulics covers the excavator side, and Case CX27B 2007 Parts Catalog – OEM Factory Specs for Mini Excavator gives you the mini-sized sibling. Same level of detail – factory prints, no aftermarket shortcuts.

FAQ – Four Questions I Actually Get

Does this catalog cover the engine internal parts like pistons and rings?

No. The catalog covers the dozer-specific assemblies: fan, radiator, undercarriage, hydraulic plumbing, and mounting hardware. Engine long-block parts are in a separate diesel engine parts manual.

How do I know this is for my 1150K Series 3 and not an earlier series?

Look at the publication year and serial number range. The catalog is labeled for “1150K Series 3 CASE CRAWLER TRACTOR (10/06- )” – that means from October 2006 production onward. If your dozer is older, you need the previous series catalog.

Can I use this to cross-reference aftermarket parts?

You can, but don’t. Aftermarket suppliers often mimic OEM numbers with subtle differences. Use the OEM number to order directly from Case or a dealer who stocks genuine parts. That’s the point.

Is this the same as the digital version Case dealers use?

Yes. This is a direct scan of the same factory catalogue. The one the dealer punches into their system? Same pages. 355 of them.

Why You Want This on the Bench

Every hour you spend chasing the wrong part costs you money and downtime. This catalog eliminates that. You get the part number, you order it, you install it. No calling three suppliers to see if a seal cross-references. No returning a fan because the bolt holes are offset by 10 degrees. The Case 1150K parts catalog is a tool, not a book. Keep it on your tablet or print the sections you need. When you’re elbow-deep in a radiator replacement and you need to confirm that lower seal part number, you’ll be glad you have it. Access the Factory Manual now and stop guessing.
