Terex Finlay I-1312 Parts Catalog

I’ve seen jobs shut down for two days because someone ordered the wrong impeller wedge or guessed at a part number from an aftermarket list. That waste stops when you have the Terex Finlay I-1312 Parts Catalog on the bench. This is the factory document – 230 pages of exploded diagrams, OEM part numbers, and ordering procedures. It’s not a reprint or a third-party compilation; it’s the same binder that ships with the machine.

Every assembly on the I-1312 crusher is broken down: chassis, track, hopper, conveyors, power units (Deutz and Caterpillar), hydraulic tanks, control valve compartments, and the entire impactor system. You get separate sections for main conveyor elements, dirt conveyor hydraulics, and the VGF feeder box. Need a breaker plate for the HSI crusher? Turn to the BREAKER PLATES chapter. Impeller bars or wedges? The IMPELLER BARS and IMPELLER WEDGES headings show the exact parts with reference numbers.

Impeller and Shafts: 3-Bar Rotor vs 4-Bar Rotor

The IMPELLER AND SHAFTS section covers both the 3-bar and 4-bar rotor configurations. Each exploded view includes the pillow block bearings (driven and non-drive sides), the shaft assembly, and the impeller wedges. If you’re swapping rotors or rebuilding the impactor, you need the part numbers from these pages – not a generic online lookup. The HYDRAULIC ASSIST COMPONENTS and SPRING BRIDGE ASM chapters give you the rest of the crusher sub-assemblies.

Engine Compartment Assemblies – Deutz and Caterpillar

Two separate engine assembly sections: DEUTZ and CATERPILLAR. Each lists every component from the fuel system to the cooling pack. The ENGINE COMPARTMENT ASM chapters group the mounting brackets, hoses, and electrical harnesses. If you’re chasing a hydraulic leak, the CAT POWERUNIT HYDRAULICS and DEUTZ POWERUNIT HYDRAULICS 1 bookmarks get you straight to the hose routing and fitting part numbers.

What Does the Hydraulic Control Valve Compartment Cover?

The HYDRAULIC CONTROL VALVE COMPARTMENT section shows the valve bank in place – every cartridge, solenoid, and manifold. The parts list includes the exact OEM valve numbers, so you’re not guessing which spool fits. Same approach for the HYDRAULIC TANK ASM and MAIN HYDRAULICS sections: the diagrams are factory prints, not redrawn aftermarket art.

7 Conveyor Sections Documented

Main conveyor, dirt conveyor, by-pass chute, feed chute, and telescopics – seven separate conveyor assembly headings. Each one lists roller part numbers, belt scrapers, and frame liners. The MAIN CONVEYOR TELESCOPICS chapter is critical if you’re replacing a damaged extension section; you get the exact OEM rail and roller part numbers.

OEM Source vs Aftermarket Catalogs

Aftermarket parts catalogs pull data from third-party databases and often use generic drawings. This catalog is printed by Terex Finlay – notice the copyright and contact information on page SP-3. The spare parts ordering procedure (Section 8) includes multilingual order forms and a spare parts index. When you call the spares line with the reference number from this manual, you get the right part. That’s the difference between a machine running tomorrow and sitting for a week. If you work on other Finlay equipment, check out the Terex Finlay J1175 Parts Catalog | OEM Factory Specifications or the Terex Finlay 694 Parts Catalog – OEM Factory Specs | AutoRepairManuals. For the J-1175 model specifically, see Terex Finlay J-1175 Parts Catalog – OEM Factory Specs.

Does this catalog include torque specifications?

No. It’s a parts catalog, not a service manual. You need the service manual for torque values and repair procedures.

What engine options are covered?

The catalog dedicates separate assembly sections to both the Deutz and Caterpillar power units. Each includes part numbers for injectors, filters, gaskets, and engine-mounted components.

Can I use this to rebuild the impactor?

Yes. The IMPACTOR ASM, BREAKER PLATES, IMPELLER AND SHAFTS, and HYDRAULIC ASSIST COMPONENTS chapters give exploded views of the HSI crusher with every bolt, liner, and wear part listed.

How do I order parts using this manual?

Section 8 contains the spare parts ordering procedure, order forms in multiple languages, and a spare parts index (page SP-20). Find the part reference number on the exploded diagram, fill out the order form with that number, and submit to the spares department. The manual includes contact information for Finlay Hydrascreens in the UK and USA.

This manual is the same one mechanics in the field use to keep the I-1312 crushing. The exploded diagrams are clear, the part numbers match factory bins, and the ordering section prevents the “I think this is the right valve” mistake. If you’re going to work on this machine, don’t waste time with generic lists. Automotive Industry Overview offers context on heavy equipment, but for parts identification, you want the factory source. Access the Factory Manual and get the right parts the first time.
