Understanding the SANY 14349644 SY335 Final Drive Sprocket Assembly: What You Need to Know

If you’re searching for a reliable final drive sprocket assembly for your SANY SY335 excavator, you’re in the right place. In this post, we’ll walk you through what the part is, why it matters, and why sourcing it from a trusted China manufacturer/supplier factory can make a big difference.

What is the “SANY 14349644 SY335 Final Drive Sprocket Assembly / Drive Wheel Assy”?

The term refers to the integrated component – the sprocket assembly (also called drive wheel assy) – compatible with the SANY SY335 excavator model. It is the part of the under-carriage system that engages the track chain and transfers torque from the final drive motor to the track links.
In effect, it’s a core part of the track drive system, combining the reduction gearbox output shaft, the hub and the sprocket teeth. Without it, your machine won’t move properly. As one aftermarket spec states for similar models: “The new final drive motor gearbox is paired to a new hydraulic drive motor … ready to bolt on.” minifinaldrives.com+2track-motor.com+2

Why this assembly is critical

• It bears heavy load and must be built from high-grade materials (e.g., heat-treated alloy steel) with hardened teeth to resist wear. For example: “Sprocket: The large, toothed wheel … made from high-carbon, heat-treated alloy steel for extreme wear resistance.” hangongmachinery.com

• It ensures correct power transmission from the final drive gear set to the track. If it fails or is overly worn, you could see the track slipping, abnormal wear on the final drive, or costly downtime.

• Maintenance is easier when you specify the correct part number and trusted manufacturer. It reduces risk of buying mismatched or low-quality part.

Key specs & what to check

When sourcing your sprocket assembly, keep in mind:

• Compatibility: Make sure it’s specified for SANY SY335 (models and serial may vary) – this part number “14349644” needs to match your machine’s requirements.

• Material & hardness: Good manufacturers will use alloy steel, cast or forged, with surface hardness in 50-60 HRC or similar. (E.g., one specification: “Surface Hardness HRC50-56” for a similar type) hangongmachinery.com+1

• Manufacturing origin & quality certification: Since you’re looking for a China manufacturer supplier factory, check for ISO 9001 certification, OEM/ODM capabilities, good material traceability.

• After-sales & support: Does the supplier provide technical support, warranty, parts availability, installation preventive advice?

• Maintenance guidelines: For example, in an operator’s manual for other models, you’ll see: “Check the sprocket for wear and proper operation” alongside final drive checks. Equipment NW+1

• Because you emphasise technological innovation and customer after-sales service, you can deliver value beyond just the component – you can address installation advice, wear monitoring, maintenance scheduling, etc.

How to select and engage with a “China sprockets manufacturer supplier and factory”

If you’re a buyer, here are steps to follow:

1. Provide your machine details: excavator make/model (SANY SY335), serial number, part number (14349644) and any drawing or dimension if available.

2. Request material & manufacturing specs: alloy steel grade, casting or forging, heat-treatment hardness, surface finish.

3. Ask for certification: ISO 9001 or equivalent, material test reports, process control.

4. Clarify delivery & logistics: lead time from order to shipment, packaging, export port, incoterm (FOB, CIF, etc).

5. Check after-sales service: technical support, warranty (hours of operation), spare parts availability.

6. Validate cost vs value: cheapest isn’t always best if quality suffers, but China manufacturers often deliver good value when properly vetted.

7. Finally, ensure the part is ready for installation — pre-assembled if possible, or easy to bolt on, and you get documentation (installation instructions, maintenance schedule) to ensure smooth use.

In short – why you’ll be glad you chose the right supplier

When you get the right sprocket assembly for your SANY SY335, installed correctly and matched with a good maintenance regime, you’ll enjoy:

• Reduced downtime (no unexpected failures)

• Longer under-carriage life and track chain life
