The Genuine SINOTRUK HOWO Gear Selection Cable (WG9900243502) is the vital mechanical link that translates the driver’s intent into precise action within the gearbox. As a crucial component among sinotruk spare parts, this cable is responsible for transmitting the lateral movement of the gear lever—the movement that selects the correct gear gate—from the cabin to the transmission’s shift mechanism.

Installation Notes
The replacement of the gear selection cable is a straightforward process, but proper routing and adjustment are critical to ensure smooth shifting.
1.Safety and Access: Ensure the vehicle is parked, engine off, and the wheels are chocked. Tilt the cabin to gain full access to the transmission’s shift tower and the cable routing path along the chassis.
2.Removal: Disconnect the cable ends from both the gear lever assembly inside the cabin and the shift tower on the transmission. Carefully remove the old cable, paying close attention to its exact routing, especially where it passes through the chassis and is secured by clamps.
3.Routing the New Cable: Route the new WG9900243502 cable along the identical path. Crucially, avoid sharp bends, kinks, or contact with the exhaust system or any moving parts. Improper routing is the leading cause of premature cable failure.
4.Connection: Connect the cable ends to the transmission shift tower first, then to the gear lever assembly. Ensure all securing clips, pins, and rubber boots are correctly installed to prevent moisture and dirt ingress.
5.Adjustment: With the gear lever in the neutral position, verify that the cable is neither pushing nor pulling the shift lever on the transmission. If necessary, adjust the cable length at the threaded end fittings until the transmission lever is perfectly centered in its neutral position.
6.Testing: Test the gear selection in all positions (engine off) to ensure the lever aligns correctly with all gear gates. Start the engine and perform a final test while stationary and then a short road test to confirm smooth, precise shifting.
