Transmission Drive Spare Parts
Getting engine power to the ground depends on a driveline that can survive shock loads, constant direction changes, and years of contamination. Parts here cover that whole path: transmissions and gearboxes, torque converters, differentials, final drives, axles, drive shafts, couplings, and the individual gears and bearings inside them. On wheel loaders, graders, and haul trucks these components take a beating, and a slipping converter or a whining final drive is rarely something you can nurse for long.
Rebuilds often start after metal shows up in the oil, a planetary fails, or a shaft spline strips — and the replacement has to match ratio, spline count, and housing exactly. 3GEN supplies 100% OEM driveline components for 40+ machine brands, with specialists who can pin down the right final drive or converter from a serial number, OEM part number, or exploded diagram. Every order ships with full tracking and free delivery to any country, most prepared in 1–2 days from stock of 3,300+ parts and delivered in 5–7 days door-to-door.
Frequently Asked Questions
What Drivetrain Parts Are Available?
We source powershift and transmission gearboxes, torque converters, final drives and travel-motor drives, axles, differentials, and drive couplings. Components suit wheel loaders, graders, dozers, and excavators across 40+ brands, all 100% OEM. Whether you need a single gear, a bearing, or a complete final drive assembly, we can quote from stock or source it.
How Do You Identify The Correct Final Drive Or Torque Converter?
These assemblies vary by gear ratio and mounting, even within one model line, so model name alone is not enough. Send the machine serial number plus any casting or tag numbers on the unit, or a technical drawing. Our parts specialists cross-reference the exact ratio and spline count, then quote the matching 100% OEM assembly.
What Causes Repeat Final Drive Or Differential Failures?
Repeat failures usually trace to contaminated oil, a blocked breather, or worn bearings left in service too long, which then damage gears and shafts. When rebuilding, renew bearings, seals, and the friction discs in one go rather than swapping a single gear. We supply the matching bearing and seal kits alongside the hard parts.
