Gear DA21708 is a precision transmission component designed for compatible commercial vehicle mechanical systems. As a toothed power-transmission element, it works with mating gears or related drivetrain components to transfer rotational motion and torque within the designated assembly.
For heavy-duty vehicles, gears operate under repeated torque, vibration, speed changes, and varying loads. Tooth geometry, material strength, dimensional accuracy, and correct installation are therefore critical to achieving reliable engagement and minimizing premature wear.
Identified by part number DA21708, this product is suitable for truck parts distributors, transmission repair workshops, fleet maintenance companies, wholesalers, and international commercial vehicle aftermarket buyers.

The Gear DA21708 is intended for compatible commercial vehicle drivetrain or transmission-related assemblies.
Gears are responsible for transferring rotational force between shafts and other mechanical components. Their tooth profile and positioning determine how effectively motion and torque are transmitted. In commercial vehicles, gears may experience substantial loads during acceleration, gear changes, climbing, braking, and operation under heavy payloads.
A gear may need inspection or replacement if abnormal noise, tooth damage, excessive backlash, vibration, or visible surface wear develops within the related assembly. Because gear wear can also result from lubrication problems or damage to mating components, the complete gear set should be inspected during service.
For transmission repair workshops, DA21708 can be used as an application-specific replacement component. Distributors and fleet operators can also stock the reference for scheduled drivetrain maintenance and repair requirements.

Gear DA21708 is a commercial vehicle gear identified by part number DA21708, designed to transfer rotational movement and torque within a compatible transmission or mechanical assembly.
A gear transfers mechanical power between rotating components while controlling the relationship between speed, torque, and rotational direction.
Common factors include high operating loads, insufficient lubrication, contamination, incorrect alignment, excessive backlash, repeated shock loading, and long-term service.
Possible symptoms include abnormal transmission noise, vibration, difficulty engaging a mechanical function, excessive backlash, or visible tooth pitting, chipping, or deformation.
No. Gear dimensions and tooth geometry are application-specific. The part number, transmission model, mounting arrangement, and mating gear specifications should be verified before purchase.
Provide the DA21708 reference together with the vehicle or transmission model, original gear photograph, dimensions, tooth count, bore details, or a physical sample.
Yes. Bulk orders can be supplied for transmission repair workshops, commercial vehicle distributors, wholesalers, importers, and fleet maintenance companies.
For qualified OEM and high-volume projects, customized tooth profiles, dimensions, materials, heat treatment, hardness, spline configuration, and other technical specifications can be evaluated.
Yes. A physical sample is useful for checking tooth geometry, dimensions, bore configuration, material characteristics, and other application-specific details.
Yes. Customer-branded labels, individual packaging, cartons, product identification, and export packaging can be arranged according to order requirements.
The tooth profile, dimensions, mating gear, shaft or spline configuration, alignment, lubrication condition, and related components should be checked to ensure the replacement is suitable.
Yes. Customers can provide OE numbers, product samples, photographs, or complete transmission parts lists for sourcing additional commercial vehicle drivetrain components.
