This shaft works in concert with the TRANSMISSION HOUSING and the HOUSING to maintain structural integrity within the gearbox.

Symptoms of Failure

• Transmission gear slipping under load: A worn 4646.354.022 shaft can cause intermittent power loss, especially during acceleration or uphill operation.
• Oil leaks near the shaft seal area: Surface wear on the shaft leads to seal degradation, resulting in visible fluid drips from the transmission housing.
• Abnormal whining or grinding noise: Bearing surface deterioration produces a high-pitched metallic sound during gear engagement.
• Vibration through the driveline: A bent or fatigued shaft creates noticeable shuddering at specific RPM ranges.
