Remanufactured Doosan D24 2.4L Long Block Overview
Remanufactured Doosan D24 2.4L Long Block is offered for Tier 4 Bobcat skid steers and track loaders in long block configuration and as a complete Drop-In engine. This remanufactured long block corresponds to the Doosan D24 engine family and is associated with listed Bobcat models S550, S650, S595, T450, T550, T650, and T595. Power options available for the D24 are 61HP and 74HP.
Product overview and listed application
The remanufactured Doosan D24 2.4L Long Block is supplied in long block configuration to address internal engine assemblies and enable shops to complete installations according to their requirements. The listed application refers to Tier 4 Bobcat equipment and the specific model identifiers noted above. Customers should provide applicable vehicle, engine, or equipment identification to assist the quoting team in matching the correct remanufactured unit and power option.
Remanufacturing process and condition
Units are disassembled, cleaned, and inspected. Internal wear items such as rings, bearings, bushings, gaskets, and seals are replaced with new components where inspection requires, and other components are repaired or re-machined to meet OEM specifications. Parts that do not meet tolerances are replaced. Some units indicate assembly in the USA. Follow the practice recommended by the original content to have a professional cleaning of the radiator and DPF filter prior to installing a replacement engine when applicable.
Internal wear items including rings, bearings, bushings, gaskets, and seals are replaced 100% with new components when required by inspection. All other components are inspected under strict guidelines to assess fit, form, and function, and parts not within tolerances are replaced. Re-machining is performed where applicable to restore mating surfaces and internal clearances to the applicable specification ranges recorded during inspection.
Product details and included components
The long block configuration concentrates on internal engine assemblies and does not automatically include external accessories such as starters, alternators, wiring harnesses, mounts, or flywheels. The exact configuration and included components are confirmed during the quote or order-review process. Provide the equipment model and any available engine identification to help confirm component compatibility and to specify whether a long block or a complete Drop-In engine is the appropriate solution.
Selecting a long block versus a complete Drop-In engine depends on installation needs and whether external components are available at the installation site. Discuss required external parts and shop capabilities with the quoting team so the formal quote specifies which items are included or needed.
Fitment and identification guidance
Accurate fitment depends on clear identification. Use the machine model identifier, any engine identification available, and the known engine displacement of 2.4L when requesting a quote. Reporting the observed power option, 61HP or 74HP, when known, assists the quoting team in selecting the correct remanufactured Doosan D24 unit and reduces the need for follow-up questions.
Documentation of dimensional checks and a list of replaced components can be supplied with the formal quote or during the order-review. This information supports parts procurement and helps a service provider plan the installation when using a remanufactured Doosan D24 engine configuration.
Ordering, quote, and contact
To request pricing or begin the order-review process, provide the equipment model, any engine identification, and the preferred configuration. The quoting team will review those details and return a formal quote that specifies the remanufactured unit configuration and any required parts. You can request a quote or call 800-355-0068 to discuss the Remanufactured Doosan D24 2.4L Long Block and confirm applicability for your equipment.

ENGINE TESTING
Every engine is machined using state-of-the-art equipment and assembled using precise and repeatable methods. All engine production follows documented lean manufacturing processes and principles to create consistent quality and dependable outcomes.
All Short Block, Long Block, and Long Block Premium are 100% Sim tested before shipment.
Complete Drop-In engines are 100% dyno tested before shipment. Computer controls ensure that each engine dyno test is conducted under standard, repeatable settings. Every engine is run through a warm-up cycle; three separate cruise segments simulating light, medium, and heavy throttle conditions; maximum torque and horsepower tests; both high and low idle tests; and a black light leak detection test with dyed oil, coolant, and fuel.
we’ve been delivering remanufactured engines for skid steer loaders for over 30 years—longer than any competitor in the industry. Our veteran machinists, many with decades of experience, follow engine-specific rebuild procedures to ensure consistent quality with every unit.
Each engine is carefully rebuilt to meet or exceed OEM specifications, using top-tier components and proven techniques. This is more than just a repair—it’s a full remanufacturing process designed to restore the engine to like-new condition.
