Daewoo S340LC-V Parts Catalog – OEM Parts Breakdown

You’ve got a machine down, the old parts diagram is smudged, and the aftermarket site gave you a part number that doesn’t match anything on the shelf. That’s when you start losing billable hours. This 524-page Daewoo S340LC-V Parts Catalog is the factory-issued parts reference — not a reprint, not a third-party compilation. It’s what the dealer’s parts counter pulls up when you call. I’ve used enough blown-up aftermarket diagrams to know: you want the OEM document on the bench before you order a single bolt.

Filter and Undercarriage Coverage

Turn to page 1 and you get a full filter schedule with OEM part numbers. Engine oil filter 65.05510-5027, fuel filter 65.12503-5011D, air cleaner elements (inner 2474-9057, outer 2474-9051), suction filter 2471-9401A, tank filter 2471-9051B — all listed with the recommended service interval in hours. Undercarriage components are broken out the same way: idler 270-00037, upper roller 2270-6126A, lower roller 2270-9025, sprocket 108-00018, track link without shoe 2272-1074, track shoe with link 2273-1049 (600G). Shoe-only part numbers for 600G, 700G, 800G, and 850G are right there. No guesswork on what roller goes where when you have the factory illustration reference.

3 Systems That Rely on Accurate Parts Identification

Every assembly in this machine — seal kits, gasket kits, electrical, drivetrain — depends on ordering the correct part number the first time. The seal kit list alone covers boom (2440-9279BKT), arm (440-00013AKT), bucket (2440-9281AKT), track spring (2270-1014AKT), center joint (2480-9405BKT), swing motor (2401-9309KT), and travel motor (2401-9264KT). Gasket kits are split between top overhaul (65.99605-8028) and all overhaul (65.99601-8042). If you’re rebuilding the engine on this Internal Combustion Engine, you need the top overhaul kit to match the cylinder head components. Mixing aftermarket gaskets on a DE12TIS is a leak waiting to happen.

Electrical Component List: Battery, Fuse, Relay

Page 1 also covers the electrical system parts. Battery 2506-6008 (150AH), fuses from 10A to 30A (2527-1016 through 2527-1025), fusible link 27A (2527-1023A), and relays including battery relay 2544-9024. If you’re chasing an electrical gremlin on the CAN Bus Network, having the exact relay part number matters — some aftermarket relays don’t handle the inrush current and fail in a month. The catalog gives you the factory-specified relay 2544-9033 for standard switching.

How to Order Parts Correctly from the Catalog

The foreword on page 5 lays out the ordering procedure. You must provide model (S340LC-V), machine serial number (found on the bed frame nameplate, format HELWO-00000), engine serial number (DE12TIS, stamped on the cylinder block), part number, description, and quantity. The parts list uses a key-numbered illustration system: each component gets a Key No. referencing the exploded view, a Part No., a Description, and Q’ty. Sub-components are marked with [.] and further sub-components with [..]. That level of detail is what you need when you’re standing in the parts department with a damaged bracket and no idea which fasteners go with it.

Source Authenticity: OEM vs. Aftermarket Parts Diagrams

This is the original factory document, reference number 021-00022BEF. It was printed by Daewoo for the S340LC-V line. Aftermarket catalogs often re-number parts or omit the sub-assembly breakdown. For example, the teeth and adapter section shows teeth 713-00032 and adapter 713-00033 — that’s a matched pair. Aftermarket sites might list a generic tooth that looks right but doesn’t index on the adapter spline. The side cutters (right 2713-6034A, left 2713-6035A) are specific to the bucket orientation. You order the wrong one and you’re drilling out pins to swap it.

If you’re also working on other Daewoo equipment, these related manuals are worth having on the same shelf: Daewoo NUBIRA Parts Catalog – 475 Pages OEM Parts Breakdown, Daewoo G20S-2, G25S-2, G30S-2 Parts Catalog – 432-Page OEM Manual, and Daewoo S035 Mini Excavator Parts Catalog.

Does this parts catalog include torque specifications?

No. This is a parts catalog — it lists part numbers, not assembly procedures or torque values. You need the service manual for torque specs on the undercarriage bolts or cylinder head fasteners.

Can I use this catalog to identify parts for a serial number outside the HELWO-xxxxx range?

The catalog is organized around the S340LC-V model. The serial number prefix HELWO indicates the production series. If your machine has a different prefix, there may be running changes not reflected here. Check the nameplate and compare with the foreword instructions on page 5 to ensure compatibility.

How do I find a specific seal kit in the 524 pages?

Use the key number index. Each illustration has a key number that points to the part number. The seal kit list is summarized on page 1 for quick reference — boom, arm, bucket, track spring, center joint, swing motor, travel motor — all with OEM part numbers.

Are the filter intervals listed in hours accurate for all operating conditions?

They are factory recommendations based on normal duty cycles. Severe conditions (high dust, continuous heavy digging) may require shorter intervals. The catalog lists the OEM part numbers; you should follow the machine’s service schedule for interval adjustments.

You’re not paying for guesswork. You’re buying a factory-published parts list that matches every bolt, seal, and filter to the machine’s original assembly drawing. The 524 pages cover everything from the top overhaul gasket kit to the halogen bulb 24V 75/70W. Access the Factory Manual and keep it on the bench next to the torque wrench.
