Product Introduction

Structure

This cabin turning bush is a one-piece integral structural bushing exclusively engineered for the pivot joint of heavy-duty truck cab suspension systems. It adopts a stepped cylindrical design, consisting of a high-strength wear-resistant alloy steel inner core and an outer layer of high-performance elastomer with a matte gray anti-corrosion finish. The top features a precision-machined counterbore structure for axial positioning, and the inner bore is a smooth, honed surface designed for a tight fit with the cab pivot shaft.

Performance

The composite structure combines the high rigidity of alloy steel and the excellent damping performance of elastomer. It can withstand the complex alternating loads of torsion, compression and shear generated during cab turning and vibration. The product maintains stable physical and mechanical properties in the temperature range of -40°C to 120°C, resisting elastomer aging, cracking and steel core corrosion.

Core Function

1. Serves as the core pivot component of the cab suspension system, connecting the cab and the chassis frame to realize the flexible turning and tilting movement of the cab.

2. Absorbs and buffers the torsional vibration between the cab and the chassis during vehicle operation, reducing the impact of road bumps on the cab and improving driving comfort.

3. Maintains the precise positional relationship of the cab pivot joint, preventing excessive play or deviation of the cab during turning and ensuring the stability of the cab structure.

Cabin Turning Bush WG1642430061 Sinotruk – Premium Replacement for Smooth Cab Tilt Operation

When your heavy-duty truck’s cab tilt mechanism starts grinding, sticking, or producing unwanted noise, the culprit is often a worn-out cabin turning bush. The Cabin Turning Bush WG1642430061 is a precision-engineered pivot bushing designed specifically for Sinotruk HOWO heavy trucks. It serves as the critical buffer between metal components in the cab tilting system, absorbing vibration, reducing friction, and ensuring your drivers can raise and lower the cabin effortlessly every single time.

At Mettlead, we supply this genuine-spec replacement bushing directly from our factory in China — which means you get strict quality control, competitive pricing, and fast delivery without the middleman markup. Whether you manage a fleet of HOWO tippers or run a parts distribution business, this cabin turning bush keeps your trucks operational and your maintenance costs predictable.

Key Features and Benefits of the WG1642430061 Cabin Turning Bush

This isn’t just a simple rubber sleeve. The WG1642430061 cabin turning bush is a carefully formulated component that plays a vital role in your truck’s daily serviceability. Here’s what makes it stand out:

• Precision Fit for Sinotruk HOWO Models – Manufactured to OEM dimensional tolerances, so it drops right into the cab tilt pivot point without modification.
• Superior Shock Absorption – The high-density composite material dampens vibration and impact loads generated during cab tilting, protecting surrounding metal brackets from premature wear.
• Low-Friction Surface – Engineered to minimize rotational resistance, which means the cab tilts smoothly even after thousands of cycles.
• Extended Service Life – Resistant to oil, grease, UV exposure, and temperature extremes commonly found in engine bay environments.
• Noise Reduction – Eliminates metal-on-metal contact that causes squeaking and clunking during cab operation.
• Cost-Effective Maintenance – Replacing a worn bush early prevents expensive damage to the tilt cylinder, hinge brackets, and locking mechanism.

In short, this small but essential part keeps the entire cab tilting system running quietly and reliably — saving you time, money, and headaches down the road.

Application Scenarios: Where Does This Cabin Turning Bush Fit?

The WG1642430061 cabin turning bush is designed for the cab tilt (turning) mechanism on Sinotruk heavy-duty trucks. More specifically:

• Compatible Vehicles: Sinotruk HOWO series heavy trucks (A7, T7H, and related models equipped with hydraulic cab tilt systems).
• Installation Position: Cab tilt pivot hinge — the rotating joint where the cabin connects to the chassis frame for forward tilting.
• Primary Function: Acts as a buffer bushing within the cab turning mechanism, cushioning impact during tilt operations and ensuring the pivot rotates smoothly without play or binding.
• Operational Benefit: Guarantees that drivers and maintenance crews can tilt the cab forward safely and effortlessly to access the engine compartment for routine inspections and repairs.

If your trucks are showing signs of difficult cab tilting, unusual noises at the hinge point, or visible wear on the pivot hardware, this bushing is very likely the component that needs replacement.

Frequently Asked Questions About the WG1642430061 Cabin Turning Bush

What exactly does a cabin turning bush do in a Sinotruk HOWO truck?

The cabin turning bush sits inside the cab tilt pivot hinge. It acts as a buffer between the rotating metal components, absorbing shock and reducing friction so the cab can tilt forward smoothly. Without a functioning bush, you’ll experience stiff tilting, metal-on-metal grinding, and accelerated wear on the hinge brackets.

How do I know when the WG1642430061 cabin turning bush needs replacement?

Common signs include unusual squeaking or clunking noises when tilting the cab, increased effort required to raise or lower the cabin, visible cracking or deformation of the existing bush, and excessive play or wobble at the pivot point. If you notice any of these symptoms, it’s time to inspect and replace the bushing.

Is this cabin turning bush compatible with all Sinotruk HOWO models?

The WG1642430061 is designed for Sinotruk HOWO heavy trucks that use this specific part number in their cab tilt mechanism. This typically includes the HOWO A7, T7H, and similar models. However, since Sinotruk produces various configurations, we recommend confirming the OEM part number against your truck’s parts manual or VIN before ordering.

What material is the WG1642430061 cabin turning bush made from?

It is manufactured from a high-density composite material — typically oil-resistant rubber or polyurethane — engineered to withstand the heat, chemical exposure, and mechanical stress found in the engine bay area. This ensures a long service life even under demanding operating conditions.

Can I order this cabin turning bush with my own brand packaging?

Absolutely. Mettlead offers white-label and fully custom packaging options. Whether you need neutral boxes for your own labeling or printed packaging with your logo and part numbers, we can accommodate your requirements. Just let us know your specifications when you contact us.

How many cabin turning bushes does a single HOWO truck typically require?

Most Sinotruk HOWO cab tilt systems use two bushings — one on each side of the pivot hinge. We recommend replacing both simultaneously to ensure even wear and balanced cab tilting performance.
