Core Components Overhaul Specification Table
| Internal Core Components | Key Functions & Manufacturing Features | Overhaul Inspection Indicators |
|---|---|---|
| Input Gear Set | Receives power from the transmission input shaft; provides step-up speed ratio transmission. | Check for gear surface pitting, micro-cracks, and chipped or broken teeth. |
| Shift Sleeve | Responsible for spline engagement and disengagement with the 10-tooth output shaft. | Check for internal spline wear and rounded or damaged edges on the engaging teeth. |
| Forced Lubrication Bushing | Maintains forced oil flow distribution during high-output operation states. | Inspect oil passages for blockage caused by micro metal debris or old gear oil sludge. |
| Viton Oil Seal Kit | Prevents gear oil leakage between the PTO housing, environment, and output shaft. | Replace immediately if the output flange shows oil sweating or weeping during hot vehicle operation. |
Structural Characteristics and Overhaul Wear Parts
Since the sandwich-type Power Take-Off (PTO) is connected directly in series with the main power transmission shaft, its internal components are susceptible to normal wear and tear during prolonged operation under heavy loads. Common maintenance and replacement components include:
1. Pneumatic Shift Cylinder and Solenoid Valve: These components control the engagement and disengagement of the PTO. If the pneumatic control seals deteriorate due to aging, it may result in incomplete gear engagement or air leakage.
2. Support Bearings and Gear Sets: Under high-load operating conditions, a lack of lubrication for the internal transmission gears can easily lead to gear stripping or thermal damage (scorching).
3. Lip Seals and Gasket Kits: Due to the direct connection with the transmission and the main shaft, wear on the front and output-end seals can easily result in leakage of the transmission gear oil.
