Build & Design
This part has a solid cylindrical gear design with external teeth and a central bore. The visible tooth profile suggests it is intended for reliable engagement with matching gears in a compact drivetrain assembly.
The metal construction is suitable for agricultural machinery, where parts must withstand:
- Rotational load
- Mechanical pressure
- Vibration
- Wear from continuous gear contact
The Z-16 tooth count is important for correct compatibility and proper gear ratio operation.
Performance
The satellite gear helps maintain smooth and controlled movement within the gear assembly. When correctly installed, it supports:
- Reliable torque transmission
- Stable gear engagement
- Reduced drivetrain play
- Proper operation of connected rotating components
A worn satellite gear can cause noise, uneven movement, excessive backlash, or accelerated wear of nearby parts, so replacement is important during drivetrain repairs.
Installation
The diagram identifies this part as position 49, making it easier to locate in the assembly. Installation should be carried out by someone familiar with MTZ gear mechanisms, as correct alignment, lubrication, and inspection of related parts are essential.
During replacement, it is also worth checking the matching axle, bushings, bearings, washers, and neighbouring gears for wear.
Value for Money
At €6.50, this is an affordable drivetrain spare part. Considering its role in gear engagement and torque transfer, it offers good value for maintenance and repair work.
Pros
- Affordable replacement part
- Correct MTZ catalogue reference
- Z-16 tooth specification provided
- Durable metal construction
- Important for drivetrain reliability
Cons
- Only available in stores
- Requires correct installation and lubrication
- Must match the exact gear assembly and tooth count
Final Verdict
The MTZ satellite gear 70-4202024 Z-16 is a small but important running gear component. It is a practical and cost-effective replacement part for restoring proper gear engagement and maintaining reliable operation in compatible MTZ assemblies.
