When shifting feels rough or gears refuse to engage under load, the problem often isn’t the clutch — it’s inside the transmission. The Synchronizer Sliding Sleeve (ສ່ວນທີບໍ່. 1310304195) plays a critical role in smooth gear changes across Sinotruk’s heavy-duty SITRAK C7H lineup.

How to Install the 1310304195 Synchronizer Sliding Sleeve – Key Tips
Before replacing this sliding sleeve, drain the transmission oil and remove the gearbox from the vehicle if possible. A clean workspace is essential — even small metal particles can damage synchronizer rings or cause misalignment.
Start by disassembling the gear cluster and inspecting spline wear on both the sleeve and the shift fork groove. If you see chipping, rounding, or deep scoring, replace the fork too — worn forks are a leading cause of premature sleeve failure.
This sleeve (1310304195) fits gears 3–4 and 5–6 in the ZF-derived 16-speed manual/AMT transmission used in Sinotruk SITRAK C7H models (2017 onward). Ensure correct orientation: the chamfered end must face toward the gear it engages.
Use light tapping with a plastic mallet if needed — never force it. Once seated, check axial movement; there should be smooth back-and-forth motion without binding. Reassemble using OEM torque specs (typically 85–95 Nm for main shaft nuts).
After reassembly, refill with SAE 75W-90 GL-5 or approved synthetic equivalent. Run through all gears with engine off first, then perform a low-load test drive (ທໍາອິດ 50 ກ້ອຢ) before returning to full duty.
