The AZ712734000211+199012340029 kit includes all necessary seals, O‑rings, backup rings, and bushings required to completely overhaul the steering gear. Each component is manufactured from high‑grade materials: the dynamic seals use a special polyurethane compound that resists abrasion and extrusion under high pressure, while static seals are made of durable NBR for excellent oil compatibility. The bushings are precision‑machined from bronze alloy to provide smooth, low‑friction operation.
All seals are designed to withstand operating pressures up to 180 bar and temperatures ranging from -40°C to +120°C. The kit includes detailed installation instructions and is packaged in a protective box to prevent damage during shipping. Each seal is dimensionally inspected to ensure a perfect match with the original steering gear components, eliminating the need for modifications and ensuring leak‑free performance.
The kit is designed for the SINOTRUK HOWO steering gear model commonly used in 6×4, 8×4, and tractor variants. By using genuine OEM seals, you restore the original steering feel and prevent internal leakage that can lead to loss of power assist or erratic steering. The AZ712734000211+199012340029 bourage redicteur ensures that your truck’s steering system remains reliable and responsive for hundreds of thousands of kilometers.

Rebuilding the steering gear with the AZ712734000211+199012340029 kit requires mechanical skill and cleanliness. Begin by removing the steering gear from the vehicle and thoroughly cleaning its exterior. Disassemble the gear according to the service manual, noting the orientation of all components. Remove all old seals, O‑rings, and bushings using appropriate tools to avoid damaging the housing. Clean all internal passages and bores with solvent and compressed air.
Install the new bronze bushings using a press or suitable driver, ensuring they are seated to the correct depth. Lubricate all new seals with power steering fluid and install them carefully, avoiding any twisting or cutting. Assemble the gear, torquing all fasteners to the manufacturer’s specifications. After reassembly, bench test the gear for smooth operation and leak‑free performance before reinstalling on the truck. The AZ712734000211+199012340029 kit is designed for SINOTRUK HOWO vehicles with ZF‑type steering gears; always verify compatibility with your specific model.
During reassembly, use a seal installation tool or a plastic cone to protect the sealing lips when passing over threads or splines. After installation, bleed the steering system thoroughly to remove any trapped air, which can cause noise and erratic operation.
Worn seals cause internal leakage, leading to loose steering and reduced power assist. The AZ712734000211+199012340029 kit restores original sealing, giving you precise control and a firm steering feel.
Oil leaks from the steering gear not only create a mess but can lead to component damage and unsafe operation. This kit provides a permanent, leak‑free seal, protecting the environment and your truck.
By replacing worn bushings and seals, you prevent metal‑to‑metal contact and reduce wear on the steering gear housing and internal parts. This extends the overall life of the steering system.
Rebuilding your existing steering gear with this genuine kit costs a fraction of a new gear. You maintain original quality while saving money.
Common signs that your steering gear needs rebuilding with the AZ712734000211+199012340029 kit include visible oil leaks around the steering gear seals, increased steering effort or free play, unusual noises (whining or clunking) when turning, and oil contamination in the power steering reservoir. If the truck wanders on the highway or requires constant correction, internal seal wear is a likely cause. During routine inspections, check for wetness around the pitman shaft and input shaft seals.
Ignoring worn steering gear seals can lead to progressive loss of power assist, eventual gear failure, and unsafe driving conditions. Rebuilding with a genuine AZ712734000211+199012340029 kit restores proper function and ensures your HOWO remains safe and easy to handle.
To extend the life of your steering gear and the AZ712734000211+199012340029 seals, maintain the proper power steering fluid level and use only the recommended fluid. Change the fluid at the intervals specified in your HOWO service manual. Inspect the steering gear for leaks during every oil change. Keep the steering gear and surrounding area clean to prevent dirt from entering the seals. Avoid holding the steering at full lock for extended periods, as this places maximum pressure on the seals.
If you operate in dusty or off‑road conditions, consider installing protective boots on the pitman shaft and tie rod ends to reduce seal contamination. Following these practices will help your rebuilt steering gear provide many years of reliable service.
Generic aftermarket seal kits often use inferior rubber compounds, incorrect dimensions, and lack critical components like backup rings and bushings. This leads to premature failure, leaks, and even damage to the steering gear housing.
