Used CATERPILLAR Cabins: Spare Parts and Complete Cabins

Used CAT cabins cover a wide range of series, from B series excavators to recent models like the 336F or 349E. Each reference is sourced from specialized dismantlers, primarily in the Netherlands, renowned for the quality of their spare parts inventory.

The machine type directly determines the cabin reference sought: a cabin for a 980K wheel loader is entirely different from that of a bulldozer or a 140H grader. Specifying the exact model allows accurate identification of the correct catalog reference.

Available parts range from complete cabins to individual components such as interior trim, mirrors, or steps. Each part undergoes inspection before shipment, ensuring compliance with original Caterpillar standards.

Cabins Available by CAT Equipment Type

• CAT excavators are the most requested family, notably B, D, E, and F series.
• Bulldozer references cover multiple generations, from D6 to D9 models.
• Compact wheel loaders, like the 914, feature a cabin with a specific panoramic view.
• CAT graders, such as series 12H, 140H, or 160H, require dedicated cabin structures.
• Backhoe loaders like the 450F or 416D have their own distinct cabin references.
• Heavy wheel loaders like the 980K use a pressurized cabin incompatible with other ranges.
• Each equipment family has variants depending on manufacturing year and series.

Excavators 320, 320F, 345D and Others

• The CAT 320 and 320F share a similar size, but their cabin structures remain incompatible between generations.
• The shift from the D series to the F series on the 320 introduces a different mounting design, modifying attachment points.
• The 345D belongs to a higher category (45 tonnes), featuring a wider cabin and reinforced ROPS mounts.
• Models 324E, 326F, and 330F use the same cabin reference 3276590, simplifying parts sourcing.
• Checking the machine's manufacturing year is essential, as two 320 models can have different cabin references.
• In F series excavators, the cabin integrates an onboard monitor whose support is fixed to the structure.
• A machine serial number allows unambiguous identification of the correct cabin reference for your CAT excavator.

Wheel Loader, Bulldozer and Enclosed Forklift

On heavy wheel loaders like the 980K or 980M, the pressurized cabin filters outside air to protect the operator in dusty environments. Its sealed design and reinforced mounts differentiate it significantly from compact loader cabins.

For bulldozers, D6, D7, and D9 series do not use the same structures: the machine’s size and engine power dictate the cabin dimensions. A late-stage D9 may require a cabin with a higher category ROPS/FOPS protection.

For CAT enclosed forklifts, the setup differs again: visibility towards the lift mast requires a specific glazed architecture with thin side pillars. Providing load capacity and series year is essential to find the exact reference.

Mini Excavators, 775F Truck, and Offset Milling Machine

• CAT mini excavators (301, 303C, 307B) have reduced cabin structures, often without integrated ROPS depending on the series.
• The 303C and 307B have specific references at Codimatra, available as new cabin structures adaptable to models.
• The articulated truck 775F features a pressurized cabin with HEPA filtration, designed for open-pit quarries and mines.
• Replacing the cabin on a 775F requires knowing the exact serial number, as two mounting variants coexist.
• The CAT offset milling machine has a swiveling cabin allowing the operator to monitor the milling drum laterally.
• Cabin orientation on the milling machine requires specific rotary hydraulic connections unique to this CAT range.
• For these three equipment types, consulting a parts specialist before ordering prevents costly reference errors.

Complete Pressurized Cabin and New ROPS Standard

A complete pressurized cabin is distinguished by its internal overpressure, preventing fine dust and hazardous particles from entering the operator compartment. ISO 10263 standard specifically regulates this level of filtration, with measurable requirements on airflow and door seal quality.

For rollover protection, ISO 12117-2 standard defines the ROPS criteria applicable to earthmoving machinery since its revision. A cabin compliant with this new standard must absorb specific lateral and vertical loads without deforming the operator survival zone.

Replacing a cabin with a non-ROPS certified used part exposes the operator to direct regulatory non-compliance. Checking the certification marking on the structure before installation is a mandatory step, especially during site inspections.

What is the Price of a Caterpillar Cabin?

• A used Caterpillar cabin can be negotiated starting from a few hundred currency units up to several thousand depending on the model.
• Cabins for mini excavators (301, 303C) remain the least expensive, often priced at the lower end of the market.
• A complete cabin for heavy excavators like the 345D represents a more significant investment in used condition compared to compact models.
• The price of a new adaptable cabin is generally lower than an original manufacturer part.
• Overall condition, donor machine hours, and presence of glazing significantly affect final cost.
• A pressurized cabin with ROPS certification commands a value higher than a simple structure, regardless of tonnage.
• Requesting a precise quote with the equipment’s serial number ensures accurate pricing tailored to your needs.

CAT Cabin Windows, Interior and Accessories

CAT cabin glazing is not just ordinary glass: depending on the model, it is laminated or tempered glass with specific thicknesses, especially the front windshield of excavators where impact resistance is crucial.

Inside, the most frequently replaced parts are the air suspension seat, dashboard, and floor coverings. On E and F series, the onboard monitor is considered a full cabin equipment element.

Accessories also include mirrors, wipers, washer fluid tanks, and steps. Each reference depends on the equipment type and generation concerned, making serial number verification essential before ordering any spare part.
