Product Introduction

• Structure: Integrated DC gear motor assembly consisting of a high-torque 24V DC motor, precision planetary gear reduction box, self-locking transmission mechanism, and plug-and-play electrical connector. It features a compact metal casing with anti-corrosion coating, built-in limit switch for stroke control, and a gear output shaft matched with the sunroof slide rail drive mechanism.

• Performance: The planetary gear reduction box provides high torque output with low noise operation, meeting the driving demand of the sunroof panel; the self-locking mechanism can fix the sunroof at any position to prevent accidental sliding caused by vehicle vibration or slope; the built-in limit switch accurately controls the opening and closing stroke to avoid mechanical collision; the fully sealed motor structure resists dust and moisture ingress in the cab environment, with stable performance and long service life.

Core Function

1. Sunroof Power Drive: Provides stable torque to drive the sunroof slide rail mechanism, realizing electric opening, closing and segmental adjustment of the cab sunroof, replacing manual operation for more convenience.

2. Position Self-locking: The self-locking transmission mechanism locks the sunroof in the set position in real time, preventing the sunroof from sliding due to vehicle bumping, braking or driving on slopes, ensuring use safety.

3. Stroke Limit Protection: The built-in limit switch automatically cuts off the power when the sunroof reaches the fully open/closed position, avoiding excessive operation and mechanical damage to the sunroof slide rail and panel.

Frequently Asked Questions – Sunroof Motor AZ16D242000151+003 Sinotruk Sitrak

Is this sunroof motor an original OEM part or an aftermarket equivalent?

This is a genuine-equivalent aftermarket part manufactured to OEM specifications. It carries the same part number (AZ16D242000151+003), shares identical dimensions, and uses the same connector type. Therefore, it functions exactly like the factory-installed unit without any performance difference.

How do I know if my truck needs this specific sunroof motor?

If your Sitrak C7H, G7S, C9H, or HOWO T5G/TX7 has an electric sunroof that no longer opens, closes partially, or makes grinding noises, the motor assembly is most likely worn out. You can confirm the part number by checking the label on your existing motor or consulting the cab’s parts manual.

Does the AZ16D242000151+003 motor come with the complete gear mechanism?

Yes. This is the complete motor assembly, including the integrated worm gear reduction mechanism, output shaft, and OEM plug connector. You do not need to purchase any additional components for a full replacement.

Can this sunroof motor operate reliably in extremely hot or cold climates?

Absolutely. The motor is rated for operation between −30°C and +60°C, which covers virtually all global climate zones—from Scandinavian winters to Middle Eastern summers. The sealed housing also prevents sand and dust ingress, making it well-suited for arid environments.

What is the expected lifespan of this replacement motor?

Under normal usage, the motor is rated for a minimum of 20,000 open-close cycles. For a typical long-haul truck that uses the sunroof a few times daily, this translates to several years of trouble-free service before any maintenance consideration arises.

Will this motor work if my sunroof glass or rail mechanism is damaged?

The motor drives the rail mechanism, but it cannot compensate for physically bent tracks or cracked glass panels. If the rail slides freely by hand when the motor is disconnected, then the motor replacement alone will resolve the issue. However, if the rail is jammed or the glass is cracked, those components should be addressed separately.
