D5N Caterpillar Bulldozer Track Shoe Assembly Forged 25MnB Steel Single Grouser Design 152.4mm Pitch Undercarriage Part

The YT-D5N-SG457 track shoe assembly serves as a direct aftermarket replacement for the Caterpillar D5N track-type tractor and the closely related D5M. Each shoe is a single grouser design spaced at 152.4 mm pitch, drop forged from 25MnB steel and hardened on the bar face to survive dozer push loads. YT machines the bolt holes and link seat accurately so the shoe clamps onto the existing chain without rework, letting a worn D5N undercarriage return to grading duty quickly.

Main Parameters

The models above are just for reference, we can't list all models here. we can supply more products as your requirements. Please feel free to send us your inquiry.

• We purchase the raw materials from famous steel group, ensures the high quality of our track shoes.
• All the track shoes are subject to through hardening processes with spray quenching technique and tempering processes.
• Strict quality control from raw material, design, technology, manufacturing for the entire process of detection.
• We can produce any requested parts according to your blue print or samples.

• Single grouser profile: One tall center bar is the standard dozer pattern, giving strong penetration in soft ground while keeping a smooth ride on firm surfaces.
• 25MnB forging material: The manganese boron grade combines deep hardenability with impact resistance, which suits the high torque loads of bulldozer pushing and ripping.
• Wear resistant bar: Induction hardening brings the grouser tip to roughly 48-55 HRC, slowing abrasion where the bar contacts soil and gravel.
• Uniform bolt pattern: The 152.4 mm pitch and machined seats match the D5N chain so every bolt pulls the shoe down evenly without bending.
• Straightened blanks: Each forging is checked and straightened so the shoe does not rock on the link when the track is tensioned.
• Corrosion protection: Oiled surfaces and a matte finish coat protect the parts during storage and ocean shipment.

*Values are reference; OEM part number confirmation advised before ordering.

1. 25MnB bar stock is spectrographically tested to verify its alloy content before cutting.
2. Heated billets are drop forged in a closed die to shape the single grouser shoe.
3. Trimming removes flash and the blank is pierced for the mounting holes.
4. Normalizing and quench tempering refine the grain and set core toughness.
5. CNC drilling and countersinking complete the bolt holes to the 152.4 mm spacing.
6. Induction hardening increases surface hardness along the grouser bar.
7. Abrasive blasting cleans the part for coating and inspection.
8. Hardness readings and dimensional checks are recorded against the drawing.
9. Rust preventive oil is applied and the shoes are bundled for export.

YT, the undercarriage brand of Xiamen Yintai Machinery Co., Ltd., has produced track components since the company was founded in 2011. As a manufacturer and exporter located in Fujian, China, YT operates forging presses, CNC machining lines and heat treatment furnaces on one site, so quality is controlled in-house from raw steel to finished shoe. The workforce of 50-100 people supports annual export revenue of USD 10-20 million, with nearly all output shipped overseas.

ISO 9001:2015 certification covers the production system, and the factory openly supports SGS or other third-party inspections. Custom work such as alternative shoe widths, special bolt types and neutral packaging is handled through the OEM and ODM service.

• Land clearing and pioneering work: The tall single bar digs into roots and loose overburden, giving the D5N the bite needed to open new ground.
• Grading and finishing passes: A clean single grouser footprint leaves a more level pad than aggressive multi-bar shoes when the dozer spreads fill material.
• Chain and shoe renewal package: Combine these shoes with YT links, pins and hardware to avoid mismatched wear between new and old running gear.
• Controlled cost maintenance: Fleet owners can standardize on one aftermarket source and cut the cost per operating hour of their dozers.
• Regional stock planning: YT can reserve production slots so replacement shoes reach your site in the same season they are needed.

This track shoe suits Caterpillar D5N and D5M dozers working on road subgrade preparation, land leveling, farm development and utility access trails. The 457 mm width offers a practical balance of flotation and penetration for a medium dozer, while the single grouser keeps steering response predictable on benches and ramps.

Precision Inspection Services

Q1: Will this shoe fit my D5N with a different shoe width?

The standard part is 457 mm wide at 152.4 mm pitch. If your D5N runs 406 mm or 508 mm shoes, tell us the width and we will supply the matching version with the same hole pattern.

Q2: Is YT an official Caterpillar supplier?

No, YT is an independent aftermarket manufacturer. We produce replacement parts to original dimensions without any affiliation with Caterpillar, and we do not mark parts with OEM numbers.

Q3: How does 25MnB compare with other shoe steels?

25MnB offers deeper hardening response than plain carbon steel, which helps the grouser bar hold its edge longer on abrasive soils while the shoe body stays resistant to shock.

Q4: Can we get a small test quantity first?

Certainly. A trial of a few pieces or a single track side is common. We will keep the same production route for your later bulk order so the test result stays representative.

Q5: What packing is used for a full set?

A full set of roughly 70-80 shoes is strapped on steel pallets with rust protection and loaded as a single unit for easy handling at your warehouse.

Q6: Do you provide warranty documents?

Yes, a 12-18 month warranty against manufacturing defects applies, and each shipment can include inspection records and a certificate of quality on request.

Shoes are oiled, grouped by batch and secured on steel pallets with plywood covers for container transport. Dimensional reports, hardness records and photos are kept per lot, and third-party inspection is welcome before shipment to confirm quantity and quality.
