Every 710-35199-6606 gear set is CNC-machined and inspected with CMM to ensure exact geometry. The 29_17 tooth profile reduces noise and increases contact ratio.
Developed specifically for heavy-duty axles, this bevel gear matches the original driveline dynamics. It ensures perfect mesh with the pinion shaft.
Carburized and hardened to 60 HRC, the 710-35199-6606 withstands shock loads and extreme wear. Service intervals increase by up to 30%.
The 710-35199-6606 parameter table is the result of thousands of hours of dyno testing. The 29_17 gear ratio offers an ideal balance between acceleration and top speed, making it the preferred choice for both on-highway and off-road applications.
29/17 = 1.705:1. This ratio delivers high torque multiplication while maintaining efficient highway cruising. Optimal for 6×4 and 8×4 chassis.
With a pitch diameter of 152mm, the bevel gear fits standard axle housings without modification. Easy drop-in replacement for existing 29_17 sets.
20CrMnTi with carburizing ensures a tough core and wear-resistant surface. This dual-phase structure prevents pitting and scoring under heavy loads.
Each 710-35199-6606 gear is 100% inspected for tooth contact pattern, runout, and backlash. Delivered with inspection report and matching serial number.
Proper installation of the 710-35199-6606 bevel gear is crucial for achieving the intended performance. Always refer to the factory service manual for torque sequences and preload settings. The 29_17 table includes the recommended bearing preload and shim thicknesses to ensure correct gear mesh.
During routine maintenance, check the backlash and contact pattern at every major service interval. The 710-35199-6606 gear set is designed to maintain its adjustment for extended periods, but periodic inspection of the axle lubricant and magnetic drain plug will reveal any early wear particles.
Use EP (extreme pressure) gear oil with GL-5 rating, viscosity 80W-90 or 85W-140 depending on ambient temperature. For the 710-35199-6606 bevel gear, the correct oil level is critical: fill until the oil reaches the lower edge of the fill plug hole with the vehicle on level ground.
The drive pinion nut should be torqued to 650–700 Nm, while the differential bearing caps require 350–380 Nm. Always use new lock nuts and cotter pins. The 29_17 bevel gear set is matched to the pinion depth, so do not mix components from different sets.
Fleet tests show a 4% fuel economy improvement due to reduced friction. The 710-35199-6606 bevel gear also lowers cab noise by 3 dB compared to standard gears.
The 29_17 ratio provides excellent gradability. The carburized case resists impact from rocky terrain, making it a trusted component for mining and construction fleets.
Many users report over 500,000 km of trouble-free operation with the 710-35199-6606 bevel gear. Regular oil changes every 50,000 km are recommended.
The 710-35199-6606 bevel gear is a direct replacement for many Howo and Sitrak axle models. Always verify your axle type and ratio before ordering. The 29_17 parameter table is included with every genuine part, ensuring you have the correct setup data.
For fleet managers and independent workshops, stocking the 710-35199-6606 reduces downtime because it fits multiple truck models. The robust packaging protects the ground surfaces and splines during shipping.

The bevel gear parameter table (29_17) is more than a list of numbers; it represents the harmony between pinion and ring gear. The 710-35199-6606 has been validated in extreme climate conditions from -40°C to +50°C, maintaining stable backlash and low noise. Its modified tooth flank profile reduces sliding velocity, which minimizes scuffing risk.
In the aftermarket, the 710-35199-6606 is often compared to lower-cost alternatives, but none match the metallurgical consistency and heat treatment control of the genuine bevel gear. The 29_17 ratio is also popular in retrofitting older trucks with modern drivetrains, offering a noticeable improvement in drivability.
When you choose the 710-35199-6606 bevel gear, you are investing in reliability. Every gear tooth is ground to a surface finish of Ra 0.8 µm, reducing friction and improving oil film retention. The parameter table includes the recommended flank radius and root fillet, which are critical for fatigue strength.
Furthermore, the 710-35199-6606 is compatible with both manual and automated transmissions. The 29_17 gear set does not require any special adaptation; it bolts directly to the existing differential carrier. This simplicity makes field replacements quick and cost-effective.
To sum up, the bevel gear parameter table (29_17) and the OEM number 710-35199-6606 are synonymous with quality. Whether you operate a single truck or a large fleet, this component will deliver consistent performance, reduce maintenance costs, and keep your vehicles on the road.
