Transmission input shaft JS180A-1701030-1 FAW - original quality from a direct supplier
When your FAW truck's transmission needs a major overhaul and the input shaft splines can no longer handle the load, every hour of downtime is costly. That's why we offertransmission input shaft JS180A-1701030-1 FAWwith factory quality control and fast shipment from the warehouse. This shaft is designed for JS180A series gearboxes and ensures trouble-free transmission of torque under the most severe operating conditions.
Mettlead is a direct Chinese supplier of spare parts for FAW, SINOTRUK, SHACMAN, WEICHAI and other leading brands. Factory prices, strict quality control, shipment from 1 piece.
Functional advantages of input shaft JS180A-1701030-1
The input shaft is the key link between the clutch and the transmission intermediate shaft. It is he who first receives torque from the engine and directs it further along the kinematic chain. Accordingly, the resource of the entire transmission directly depends on its reliability.
Why choose this shaft
- Precise spline geometry— ensures tight engagement with the driven clutch disc without backlash or vibration, which extends the life of the synchronizers.
- High strength alloy steel— the shaft is made of material that has undergone heat treatment (cementation + hardening), which guarantees a surface hardness of at least 58 HRC.
- Original fit dimensions— full compatibility with bearings, seals and gearbox housings of the JS180A series without modifications during installation.
- Resistance to cyclic loads— the shaft is designed for long-term operation under variable torque, which is especially important for quarry and construction equipment.
- Factory control— each shaft is tested for runout, alignment and compliance with tolerances before shipment.

Application scenarios and compatibility
Adaptable technology models
Primary shaft JS180A-1701030-1 is designed for trucksFAW Jiefang, equipped with a JS180A series gearbox. In particular, it is installed on the following models:
- FAW J6P (tractors and dump trucks with 350–460 hp engines)
- FAW J6L (medium-duty trucks)
- FAW J5 (previous generation of long-haul tractors)
Typical replacement situations
During operation, the input shaft is subjected to enormous loads. Here are the most common reasons why it needs to be replaced:
- Transmission overhaul— when completely overhauling the gearbox, replacing the input shaft is a standard procedure, since even slight wear of the splines affects the operation of the entire gearbox.
- Worn input shaft splines— manifested by a characteristic knocking sound when changing gears and vibration at certain speeds. Worn splines do not provide tight contact with the clutch disc.
- Damage to bearing seats— scuffing or wear of the shaft journals leads to increased clearances, noise and accelerated destruction of bearings.
- Fatigue cracks— during prolonged use in difficult conditions (quarries, mountain roads), microcracks may develop, threatening sudden destruction of the shaft.
OEM/ODM - custom production capabilities
Mettlead not only supplies standard spare parts, but also offers flexible terms of cooperation for wholesale buyers and distributors:
- White-label packaging— we will produce a batch of input shafts JS180A-1701030-1 under your own brand. You receive the finished product with your markings, labels and branded box.
- Custom packaging— it is possible to change the size of the box, add installation instructions in the desired language, and apply QR codes for tracking.
- Strict quality control— before shipment, each batch undergoes a three-stage inspection: incoming inspection of raw materials, intermediate inspection at production and final inspection before packaging.
- Flexible volumes- from single samples for testing to container lots with a fixed delivery schedule.
In addition, we invite potential partners to visit the production site in China to personally see the quality of the products and discuss long-term terms of cooperation.
Customer case: JS180A-1701030-1 input shaft replacement for a fleet in Central Asia
At the beginning of 2024, we were contacted by a transport company from Uzbekistan operating a fleet of 40 FAW J6P dump trucks in mountain quarries. The problem was the massive wear of the splines of the transmission input shafts - due to constant overloads and frequent gear shifts on inclines, the service life of the shafts was reduced by almost half the standard.
After contacting, our engineer conducted a detailed consultation and confirmed compatibilityinput shaft JS180A-1701030-1 FAWwith a modification of the gearbox installed on their equipment. A trial batch of 10 pieces was issued. Within 5 days, the shafts were delivered to Tashkent by air.
Result: after installation and running-in for 3 months, not a single shaft required replacement. The client appreciated the stability of quality and issued an annual contract for the supply of 120 units with quarterly shipment. In addition, the customer chose the custom packaging service with markings in Uzbek for their internal warehouse.
Frequently asked questions about input shaft JS180A-1701030-1
What is the difference between the JS180A-1701030-1 input shaft and the JS180-1701030?
The suffix “-1” in the number indicates a modernized version of the shaft with a modified spline profile. This means that when ordering, you must accurately check the number with the catalog of your gearbox. If you are not sure about compatibility, send us a photo of the old shaft and gearbox nameplate, and our engineer will confirm the applicability.
What is the real life of this input shaft under severe operating conditions?
With proper installation and the use of high-quality gear oil, the shaft can withstand from 150,000 to 250,000 km, depending on conditions. On quarry equipment, the service life may be lower due to increased shock loads, but it is completely comparable to the original part.
Is it possible to install this shaft without completely disassembling the gearbox?
No. Replacing the input shaft of the JS180A-1701030-1 transmission requires removing the gearbox from the vehicle, removing the clutch bell and disassembling the front part of the gearbox. We recommend performing this operation in a specialized workshop using pullers and stands.
How to check the input shaft for wear before removing the gearbox?
Indirect signs of wear are: increased noise in the clutch zone in neutral gear, vibration when starting, difficulty engaging first and reverse gears. An accurate diagnosis is only possible after disassembly and visual inspection of the splines and journals of the shaft.
Does the shaft come with bearings and seals?
The standard package includes only the input shaft itself. However, we can complete the order with all the necessary bearings, retaining rings and seals for the JS180A gearbox. Just indicate this when submitting your request, and we will prepare a complete repair kit.
