Terex Finlay J-1175 Parts Catalog

Anyone who has tried to rebuild a jaw crusher or replace a track group on a Terex Finlay J-1175 using a blurry photocopy or a third-party PDF knows the drill. You get a part number that doesn’t match, a diagram that skips the hardware, and you spend billable hours cross-referencing with the dealer. That’s not the kind of work I call productive. This Terex Finlay J-1175 Parts Catalog is the OEM factory document – 228 pages of exploded assembly drawings, indexed part numbers, and the official ordering procedure. It’s what you put on the table when you need to know exactly which bearing, seal, or bolt goes where.

What This Parts Catalog Actually Contains

The table of contents starts where it should – with the chassis assembly (CHASSIS ASM) and works through every major subsystem. You get the diesel tank, the track undercarriage split into drive sprocket, final drive, idler/recoil/tensioner, repair kit groups, roller groups, and the full trackline. Each section has its own exploded view with callouts tied to the parts index. The SOLENOID BLOCK BREAKDOWN (partcode 10.42.0040) is drawn out so you can see the cartridge valves and coils without guessing. If you’ve ever had a hydraulic lockup because you ordered the wrong spool, you know why that matters.

Track Undercarriage: Exploded Views That Make Sense

TRACK DRIVE SPROCKET ASSEMBLY, TRACK FINAL DRIVE UNIT ASSEMBLY, TRACK IDLER,RECOIL AND TENSIONER ASSEMBLY – these are listed individually, not lumped into one vague “track group” drawing. You get a separate page for the repair kit hardware. When you’re ordering sprocket segments or track chains for a J-1175 that’s been working limestone, the last thing you need is a generic diagram. This catalog gives you the OEM part numbers from the Terex Finlay supply chain. Compare with Terex Finlay J1175 Parts Catalog | OEM Factory Specifications for the J-1175 if you want the exact same data in a different format – but this is the original.

Jaw Crusher Assembly: The Heart of the Machine

JAW ASSEMBLY, HYDRAULIC PULLROD, PULLROD CONTROL ASM, CROSS SECTION THROUGH JAW CRUSHER, JAW CROSS SECTION THROUGH SHAFT, JAW BEARING ASM (FIXED and FLOATING), SETTING ADJUSTMENT ARRANGEMENT – that’s eight separate sections just for the crushing head. Each one shows the bearings, seals, wedges, and adjusting plates with the correct fastener grades. If you’re swapping out a fixed jaw bearing on a Saturday afternoon, the exploded view on that page tells you which retaining rings and snap pliers you need. Terex Finlay 694 Parts Catalog – OEM Factory Specs | AutoRepairManuals covers a different model, but the same philosophy applies: factory drawings beat aftermarket redraws every time.

Hydraulic System Breakdowns – Don’t Guess the Hose Routing

MAIN BUILD HYDRAULICS 1 through 4, plus separate sections for HOPPER HYDRAULICS, DIRT CONVEYOR HYDRAULICS, MAIN CONVEYOR HYDRAULICS, JAW HYDRAULICS, PULLROD HYDRAULICS, and POWERUNIT HYDRAULICS 1-3. That’s 11 hydraulic schematics. Each one shows the hose routes, fittings, and block orientations. I’ve seen guys hook up a conveyor line backwards because they used a generic diagram – cost a day of labor and a new seal kit. This catalog prevents that. The part numbers for O-rings and tube assemblies are listed next to the drawing. Working on the boom arm option? There’s a dedicated section for HYDRAULIC BOOM ARM HOSES (OPTION). Terex Finlay I-1312 Parts Catalog uses the same deep-dive structure for another crusher line.

CAT C9 Powerunit: Engine and Powerpack Components

CAT C9 POWERUNIT ASM, CAT C9 ENGINE ASM, and CAT C9 POWERPACK ASM are three separate sections. The powerunit assembly covers the base engine, the powerpack includes the radiator, aftercooler, and mounting brackets. If you’re troubleshooting a coolant leak, you want the powerpack drawing – not the longblock diagram. The catalog even breaks out the C9 LOOM ELECTRIC SCHEMATIC and the main ELECTRIC SCHEMATICS FROM SERIAL NO. FNC580696 INCLUDING FNC580660 & FNC580684. That’s critical when you’re replacing a harness on a machine that’s had field modifications.

Electric Schematics: The Difference Between OEM and Aftermarket

J-1175 ELECTRIC COMPONENTS 1 and 2 are listed in the TOC, and the actual schematics are at the back of the catalog. Aftermarket reprints often consolidate multiple pages into one blurry image, losing the connector pin numbers. This OEM document keeps the original layout. The solenoid block breakdown (partcode 10.42.0040) is referenced in both the hydraulic and electric sections. You can trace a no-crank condition from the starter relay back through the control box ASM without guessing which wire goes where. For broader context on why OEM documentation matters in the Automotive Industry Overview, the same principles apply to heavy equipment: accuracy starts at the factory print.

Audience Fit – Who Needs This on the Bench

If you’re a shop owner with a J-1175 in the yard and a technician who’s never torn one down, this catalog saves you from ordering wrong parts and waiting for returns. Home mechanics tackling a full rebuild need the exploded views and the spare parts ordering procedure (Section 8, pages SP-1 to SP-20). The manual includes multilingual instructions, but the drawings and part numbers are universal. For the rig mechanic who works on several Terex Finlay models, having this alongside the Automotive Industry Overview may seem odd, but understanding supply-chain consistency helps when you’re ordering from a dealer. Automotive Industry Overview gives background – this catalog gives you the actual numbers.

Is this the service manual or the parts catalog?

It’s the parts catalog – 228 pages of exploded assemblies and part number lists. You still need the Service & Repair Manual for procedures and torque specs. This catalog is for ordering the right pieces.

Can I use this to rebuild the CAT C9 engine?

The catalog includes the C9 powerunit and powerpack assemblies, but it does not contain internal engine component breakdowns like pistons or rings. That would be in the engine service manual. You can order the external hardware (brackets, hoses, mounts) from here.

Does it cover the electric schematics after serial number FNC580696?

Yes. The TOC lists “ELECTRIC SCHEMATICS FROM SERIAL NO. FNC580696 INCLUDING FNC580660 & FNC580684”. That covers the later production machines. Earlier serial numbers may need the previous revision – check your machine’s serial before buying.

Are the part numbers still current for a 2025 rebuild?

Terex Finlay revises part numbers over time. This catalog reflects the original release. Always verify with your dealer for superseded numbers. The catalog gives you the starting point – it’s far better than a generic part list found online.

When you’ve got a J-1175 down for undercarriage work or a jaw bearing replacement, you need the part numbers in front of you, not on a slow dealer lookup. Access the Factory Manual – the 228-page OEM PDF that puts every assembly drawing and part code at your fingertips. You’ll save the first round of false orders on the first job.
