Analysis Of Problems Of Fast G170rt-11509c Gearbox

Description of machining defects on 11203 release bearing seat of fast G170 rt-11509c transmission

As a distributor of Shaanxi fast, the service and quality of fast’s products can be said to be superior to domestic heavy truck parts manufacturers. In our cooperation in recent years, there are basically no product quality problems. However, recently, users have reported that among fast’s products, the release bearing seat in the most popular g170rt-11509c gearbox can not work normally after installation. Therefore, we checked the release bearing pedestal in the company’s inventory.

Phenomenon:

Analysis:

If this kind of bearing pedestal is forcibly assembled, it may not be installed or the clutch engagement is not complete (slipping) without adjusting the position of the release ring of the clutch pressure plate; if the position of the release ring of the clutch pressure plate is adjusted for installation, the clutch will not be completely separated after the interference area is naturally worn due to frequent gear shifts.

In view of the above pictures and cause analysis, it is recommended that the manufacturer recall this batch of release bearing pedestal, reprocess it, and sell it after reaching the factory standard!
