308D or 308E pulling to one side or final drive making grinding noise? A worn 452-6208 final drive assembly loses both motor efficiency and gearbox reduction accuracy, making equal bilateral tractive effort impossible on grades. RITO supplies this complete two-speed final drive assembly to restore full 308-series tractive force and straight-line travel.

FAQ
Q: How to diagnose whether the motor or gearbox section of 452-6208 has failed?
A: Test motor case-drain flow at rated travel pressure. Above OEM spec confirms motor section wear. Normal case drain with audible gear noise and metal in gearbox oil confirms gearbox failure. The complete assembly covers both.
Q: Does the 452-6208 two-speed function need recalibration after installation?
A: Two-speed shift is hydraulically controlled by the machine travel speed selector valve. No motor calibration is required after installation. Verify the speed shift pilot circuit pressure is within spec if speed shift response is slow.
Q: What gearbox oil should I use after fitting the 452-6208 on a 308D?
A: Use EP 90 or EP 140 gear oil as specified in the Caterpillar 308D service manual. Fill to the correct level and change after the first 50-hour break-in period.
Q: How to confirm 452-6208 is correct for my Cat 308D?
A: Match existing final drive part number 452-6208 or 4526208 and confirm machine model is 308D, 308E or compatible 307/308-series. Provide machine serial number for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
