Replacement Recommendations
Confirm part number and applicable transmission model.
Different transmission models such as HW19710 and HW19712 use different internal parts. Verify the part number and its application range before ordering. For example, AZ2210020501 is only applicable to HW19710T.
Inspect associated components.
When replacing the input shaft, we recommend simultaneously inspecting the input shaft bearing and transmission housing for wear or damage.
Genuine or OEM-grade quality preferred.
Non-genuine parts may lead to gear slippage, overheating, or complete transmission failure. Skyond supplies parts manufactured to OEM material and process specifications.
Proper installation procedures.
Rough handling during installation is a common cause of gear chipping and other serious failures.
Provide VIN or photos of old parts.
If you are unsure of the specific part number, provide the chassis number or clear photos of the old parts to our technical team for accurate matching.
Reasons to Choose Skyond for Transmission Parts
1. Transmission parts are not interchangeable across models we help you get it right.
HW19710 and HW19712 gearboxes look similar but use different internal components. Ordering the wrong part wastes time and money. Our technical team knows Sinotruk and Fast Gear transmission variants — we verify compatibility before you order.
2. We stock the parts you need for scheduled and unscheduled repairs.
Gear sets, bearings, synchronisers, and clutch components are maintained in inventory. Most confirmed orders ship within 6-7 days.
3. One transmission repair often needs multiple parts.
Replacing gears may also require bearings, seals, and shift forks. We supply the full set of associated components — one order, one shipment.
4. We supply components that meet OEM specifications.
Gears are manufactured with the correct tooth profile, hardness, and surface finish. Bearings meet the load ratings required for heavy-haul applications. Clutch components engage smoothly and consistently.
Quality Promise
Skyond's Sinotruk Transmission Parts are manufactured to original equipment standards. Gears are produced from case-hardened alloy steel with controlled tooth profiles and surface hardness. Shafts are machined to precise tolerances for bearing fit and alignment. Synchroniser assemblies are manufactured with friction materials selected for wear resistance and consistent engagement. Seals and gaskets meet original specifications for fluid retention. Each component is inspected for dimensional accuracy before shipment. Manufacturing facilities are IATF 16949 certified.
Frequently Asked Questions
Q1: How do I identify the correct transmission parts for my vehicle?
Provide your vehicle model, transmission model (such as HW19710 or HW19712), and the part number from the original component. Our technical team can verify compatibility.
Q2: Are Skyond transmission parts compatible with Fast Gear transmissions?
Yes. We supply a full range of components for Fast Gear 10-speed and 12-speed transmissions, including synchronisers, gears, bearings, and clutch components.
Q3: What are the signs of transmission wear?
Common signs include: jerky or difficult shifting, unusual noise from the transmission area, oil leaks, and gear disengagement during operation.
Q4: Should I replace the clutch components when rebuilding a transmission?
We recommend inspecting clutch components and replacing them if they show signs of wear. Replacing related components during a transmission overhaul helps prevent premature failure of new parts.
Q5: What is the warranty on Sinotruk transmission parts?
Skyond provides a 12-month warranty covering manufacturing defects in materials and workmanship.
