With the Fork shaft assembly, you can restore the shifting precision of your HOWO Max 4X2, reducing shift effort and preventing gear clash. Trust in HOWO’s engineering and the quality of this Fork shaft assembly to keep your truck performing at its peak.
The Fifth/sixth gear shift fork shaft is the central actuating rod of this Fork shaft assembly, responsible for translating the driver’s shift motion to the fifth and sixth gear synchronizer sleeves. This precision-ground shaft is manufactured from high-carbon steel with induction-hardened bearing surfaces, providing exceptional wear resistance and dimensional stability. Its precise diameter and surface finish ensure low-friction movement within the shift rail bushings, reducing shift effort and improving feel.
The Fifth/sixth gear shift fork shaft features precisely located grooves and detents that engage with the shift block and fork, ensuring accurate positioning during gear selection. Its hardened ends are designed to interface with the shift mechanism, providing a durable connection point for the shift cables or rods. Replacing a worn or bent shaft with this genuine component restores the precision of the Fork shaft assembly, ensuring positive engagement of fifth and sixth gears.
This Fifth/sixth gear shift fork shaft is a critical part of the Fork shaft assembly, providing the linear motion needed for smooth and accurate gear changes. Its robust construction guarantees long-term reliability, even under the high loads of heavy-duty trucking.
The Tab is a precision-machined metal plate that attaches to the shift fork shaft, providing a positive engagement surface for the shift block. This component is a key part of the Fork shaft assembly, ensuring that the shift fork is securely connected to the shaft and that the axial movement is accurately transmitted to the synchronizer sleeve. Its precise dimensions and hardness guarantee consistent shifting performance.
Manufactured from high-strength steel with a corrosion-resistant coating, the Tab is designed to withstand the repeated impacts and wear associated with frequent gear changes. Its precisely located mounting holes ensure a perfect fit with the shaft and fork, eliminating play and ensuring positive engagement. Replacing a worn or damaged Tab with this genuine component restores the integrity of the Fork shaft assembly, preventing shift fork disengagement and ensuring reliable gear selection.
The Tab is an essential part of the Fork shaft assembly, providing the mechanical link between the shift fork shaft and the shift block, ensuring accurate and consistent gear changes.
The Reverse gear shift block is a precision-machined component that interfaces with the shift fork to engage reverse gear. This block is designed to provide a positive, repeatable engagement surface for the shift fork tab, ensuring that the reverse idler gear is correctly positioned for smooth engagement. Its hardened steel construction resists wear and deformation, maintaining consistent shift quality over the long term.
The Reverse gear shift block is precisely machined to match the shift fork profile, providing a smooth, low-friction interface that reduces shift effort. Its accurate dimensions ensure that the fork is positioned correctly relative to the reverse gear mechanism, preventing misalignment and gear clash. Replacing a worn or damaged shift block with this genuine component restores the precision of the Fork shaft assembly, ensuring that reverse engages smoothly and reliably.
The Reverse gear shift block is a critical part of the Fork shaft assembly, providing the wear surface that interfaces with the shift tab, ensuring consistent and accurate reverse gear selection.
The Pin is a precision-ground cylindrical fastener used to secure the shift fork to the shaft, ensuring a rigid connection that transmits axial and radial forces accurately. In the Fork shaft assembly, two pins are used to lock the fork in position, preventing any relative movement that could lead to misalignment or premature wear. These pins are manufactured from high-strength alloy steel with a hardened surface, providing excellent shear strength and wear resistance.
The Pin is designed for an interference fit, ensuring that it remains securely in place even under high vibration and load. Its precise diameter and length match the shaft and fork bores, guaranteeing a snug fit that eliminates play. Replacing a worn or damaged pin with this genuine component restores the rigidity of the Fork shaft assembly, ensuring that the shift fork remains accurately positioned for consistent gear engagement.
The second Pin in the Fork shaft assembly provides redundant securing for the shift fork, ensuring that the connection remains rigid even under the most demanding conditions. This pin is identical to the first pin in material and dimensions, but its placement on the opposite side of the fork ensures balanced clamping force and eliminates any possibility of fork rotation or axial play. Together, the two pins create a fail-safe attachment that guarantees the fork remains correctly aligned with the synchronizer sleeve.
The Pin is an essential part of the Fork shaft assembly, providing the secure fastening needed to maintain the alignment and integrity of the shift fork mechanism.
