Turbo Charger Repair Kit Rebuild Parts for 721164 17201-27030

The GT1749V turbocharger repair kit is a comprehensive solution designed for the professional restoration and maintenance of variable geometry turbochargers. 

This rebuild kit is engineered to meet OEM specifications, ensuring perfect fitment, durability, and optimal performance for a wide range of vehicles 

equipped with GT1749V turbos. It includes essential components that allow mechanics and turbo specialists to repair 

worn or damaged turbos without the need to replace the entire unit—saving both time and cost.

Purpose and Function

Over time, every turbocharger experiences wear caused by high-speed rotation, heat, and oil contamination. Symptoms such as oil leaks, 

whining noises, reduced boost pressure, or excessive smoke indicate internal wear. The GT1749V turbo repair kit is developed to restore your turbo’s 

performance by replacing critical components responsible for bearing support, lubrication, sealing, and stability. With this kit, 

you can rebuild a used or damaged GT1749V turbocharger back to near-new condition, ensuring efficient boost response and engine reliability.

Kit Contents and Applications

The repair kit includes a set of premium components designed for precise compatibility with the following

turbo models and part numbers: 721164, 17201-27030, 721021, 713672, 716215, and 758219.

Typical contents of the GT1749V rebuild kit include:

• Journal bearings (721164): Support the turbo shaft and provide smooth rotation at high speeds, reducing friction and wear.

• Thrust bearing and collar (17201-27030): Handle the axial loads produced by the turbine and compressor wheels, 

preventing excessive shaft movement.

• Seal rings (721021): Maintain oil pressure and prevent oil leakage into the compressor and turbine housings.

• Retaining clips and spacers (713672): Secure bearing components and maintain correct clearances during high-speed operation.

• Shaft nut and bolts (716215): Used for precise assembly and balancing of the rotor group.

• O-rings and gaskets (758219): Ensure proper sealing between turbo components and prevent exhaust or oil leaks after reassembly.

These parts are produced from high-grade steel alloys and heat-treated for enhanced durability and resistance to high temperatures and friction. 

The materials and tolerances are designed to meet or exceed OEM standards.

Advantages of Using the GT1749V Rebuild Kit

1. Cost-Effective Restoration: Rebuilding a turbocharger with this kit costs a fraction of purchasing a new turbo. It provides the same performance when properly installed and balanced.

2. 
   

2. OEM-Level Precision: Each component is machined to factory tolerances, ensuring perfect alignment and operation after assembly.

3. Improved Reliability: Replacing worn bearings and seals restores oil pressure balance and prevents future oil leaks or premature failures.

4. Compatibility and Versatility: The kit fits a wide range of GT1749V applications commonly used in diesel engines from brands such as Hyundai, Kia,

 Volkswagen, and Toyota (depending on the specific part numbers listed above).

5. Enhanced Performance: Once rebuilt, the turbocharger can deliver consistent boost, improved acceleration, and optimal fuel efficiency, similar to a new unit.
