29070012671 SUN GEAR 17X41 TEETH-800107328 (A-36)

Product Name: Sun Gear — core gear component of the planetary reduction mechanism in wheel loader drive axles

Function: Installed in the loader drive axle (planetary reduction mechanism of the final drive / wheel hub), the sun gear meshes with the planet gears and ring gear to transmit power with speed reduction and torque increase. Wear or tooth breakage of the sun gear can cause axle noise, loss of power, or even failure of travel. It is a critical wear-prone component of the drive system.

Applications:

• Shandong Lingong (SDLG) loaders: LG936, LG953 / LG953N, LG956 / LG956L, LG958 / LG958L, L956F, and ZL50 / ZL60E series, etc.
• Also compatible with: LiuGong CLG856H, XGMA ZL50, XCMG and other ZL50-class wheel loaders (verify tooth count)

Interchangeable / Related Part Numbers: 29070012671 = 83666203 = 4110001903084 (interchangeable across different numbering systems)

Key Features:

• Tooth count: 17 teeth (some configurations use a 17–41 tooth combination; please verify against your machine model)
• Approx. weight: 5.2 kg per piece
• Made of high-strength alloy steel with carburized and hardened tooth surfaces for wear and impact resistance

Replacement Notes: Verify tooth count, module and machine model before ordering. The sun gear usually wears together with the planet gears and ring gear — it is recommended to replace them as a set, check bearings and spline fit, and assemble to the specified torque.
