HW15710 gearbox assembly part

Product Description


SINOTRUK Truck Transmission System / Pneumatic Gear Shift Control System Parts Pneumatic Lock Valve Assembly WG2203250010


The WG2203250010 Pneumatic Lock Valve Assembly is the lock valve in the SINOTRUK HOWO transmission's pneumatic circuit, running on compressed air to control the interlock for the range-shift mechanism — once the main gearbox is in gear, it shuts off the air passage to the range section so the range box can't be shifted at the wrong moment, which protects the range-section synchronizer from a mistimed range change. It sits in the transmission air pipe and valve assembly, listed in the parts book alongside the WG2203250003 Double H valve, air fittings, springs, bushings, O-rings, and gaskets, and it is strictly a transmission air-circuit part — not a brake valve and not a cab air valve. On multi-speed boxes like the HW15710, it works with the shift circuit to keep the main gearbox and the range section in step. When you replace it, check the whole circuit at the same time — air lines, fittings, O-rings, gaskets, and the Double H valve — because a leak or a restricted line anywhere in the circuit throws the same symptoms as a failed lock valve, so swapping the valve alone won't always clear the fault. This part fits transmission overhauls, pneumatic shift-system repairs, and lock valve replacement on compatible SINOTRUK HOWO trucks.

FAQ


Q1: What are possible signs that the lock valve needs inspection?

Possible symptoms include:

  • Range gear cannot be selected correctly
  • Range shifting becomes inconsistent
  • Delayed pneumatic response
  • Abnormal air leakage
  • Range section remains locked
  • Incorrect interaction between the main gearbox and the range section

The air hoses, connectors, Double H valve, and other pneumatic components should also be checked before replacing the valve.





Q2: What should be checked before installing a replacement?

Before installation, inspect the transmission air circuit for air-line leakage, blocked passages, damaged O-rings, loose fittings, and incorrect hose routing. Confirm that the valve operates correctly with the Double H valve and range-shift mechanism before returning the truck to service.



Q3: What should buyers check before ordering?

Confirm:

  • Part Number: WG2203250010
  • Truck model
  • Transmission model
  • Pneumatic circuit configuration
  • Airport dimensions
  • Valve mounting position
  • Existing valve and connector configuration

اشتريتُ قبل ثلاثة أسابيع حشوات زيت متينة لشاحنات أسطولي من شركة HOWO من هذا المتجر المستقل. بصفتي مدير أسطول أدير 22 شاحنة نقل بضائع في لاغوس، كنتُ بحاجة إلى حشوات مطاطية متينة تتحمل درجات الحرارة العالية على الطرق الأفريقية الوعرة. كل حشوة تناسب تمامًا دون أي تسريب للزيت أثناء النقل لمسافات طويلة. استغرقت الشحنة إلى ميناء لاغوس 8 أيام فقط، وكان فريق المبيعات سريع الاستجابة عندما طلبتُ أسعار الجملة.
