ZF 0735.470.220 ROLLER SET | OEM Genuine Part

Overview

The ZF 0735.470.220 ROLLER SET is a precision-engineered OEM genuine component designed to reduce friction and support axial and radial loads within the planetary gear sets of heavy-duty ZF transmissions. This roller set sits directly between the sun gear and the planetary carrier, ensuring smooth torque transfer during high-stress operations in construction machinery. The SKU 0735.470.220 is a critical wear item that must be replaced in conjunction with the 2094101012 TRANSMISSION HOUSING to maintain proper alignment and prevent premature gear failure.

Symptoms of Failure

• Gear slipping under load: Worn rollers cause inconsistent engagement between planetary gears, leading to power loss during excavation or lifting.
• Metallic grinding noise: Deteriorated roller surfaces produce a distinct high-pitched whine or grinding sound, especially when shifting between forward and reverse.
• Increased operating temperature: Excessive friction from a failing roller set generates heat, often triggering transmission overheat warnings on the dashboard.
• Oil contamination with metal particles: Flaking roller material circulates through the hydraulic system, damaging seals and valves.

Technical Specifications

Compatibility

This roller set is engineered for ZF heavy-duty transmission models commonly used in wheel loaders, dozers, and graders. Compatible platforms include the ZF WG180, WG200, WG210, and WG220 series. It also fits select ZF 4WG-200 and 5WG-210 variants. For proper installation, always pair this part with the 2094301036 HOUSING and the 2094298057 HOUSING to ensure correct roller cage retention. The 2094301071 COVER must also be inspected for wear during roller replacement.

“name”: “Can I replace the 0735.470.220 roller set without removing the transmission housing?”,
“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “No. Replacing this roller set requires disassembly of the transmission housing (part 2094101012) and related housings (2094301036, 2094298057) to access the planetary gear set. Always inspect the cover (2094301071) and seals during this procedure.”
