Confirm your working conditions including vehicle type, load weight and road environment. Pick transfer case, reducer or transmission for engineering machinery, commercial truck or new‑energy equipment accordingly.
Verify rated torque, speed ratio and power requirements. Improper parameter matching will cause overheating, accelerated wear and unexpected drivetrain failures during operation.
Compare installation dimensions, shaft interfaces and bolt hole positions. Correct mounting size ensures direct replacement without extra modification for your existing assemblies.
