ZF 0630.100.495 TOOTHED DISC | OEM Genuine Part

Overview

The ZF 0630.100.495 TOOTHED DISC is a critical friction component engineered for precise torque management within heavy-duty construction machinery transmissions. This OEM genuine part sits directly within the clutch pack assembly, where it engages with hydraulic pressure to transfer power smoothly from the engine to the drivetrain. Designed to withstand extreme thermal and mechanical loads, the SKU 0630.100.495 ensures reliable gear engagement and minimal power loss during demanding operations such as earthmoving and material handling. When paired with the 2093140001: HOISTING UNIT, this toothed disc forms the backbone of a robust power transmission system.

Symptoms of Failure

• Delayed or harsh gear engagement: When the toothed disc wears thin, hydraulic pressure cannot clamp the clutch pack effectively, causing noticeable lag or jerky shifts during acceleration.
• Torque loss under load: A worn 0630.100.495 disc slips under heavy strain, leading to reduced pulling power in construction machinery—often mistaken for engine problems.
• Metallic grinding noises: As friction material erodes, steel-on-steel contact produces a distinct grinding sound from the transmission housing, especially during gear changes.
• Overheating transmission fluid: Excessive slippage generates abnormal heat, causing fluid to darken and emit a burnt odor, which accelerates wear on adjacent components like the 2093240001: LIFTING SHAFT.

Technical Specifications

Compatibility

This toothed disc is primarily designed for ZF WG180 and WG200 series transmissions commonly found in wheel loaders, excavators, and telehandlers. It also fits select ZF 4WG-180, 4WG-200, and 6WG-200 variants used in construction machinery from manufacturers like Liebherr, Caterpillar, and Volvo. For optimal performance, always replace the disc alongside the 2095340002: BUSH and 2093340007: BRACKET to maintain proper clutch pack alignment and hydraulic pressure.

Frequently Asked Questions

Q: How do I know if the 0630.100.495 toothed disc needs replacement?
A: Check for burnt transmission fluid, delayed shifting, or visible wear on the disc’s friction surface. If the disc thickness measures below 3.0 mm, immediate replacement is recommended to avoid damage to the clutch pack.

Q: Can I install this disc without replacing the associated bush and bracket?
A: While possible, it is strongly advised to replace the 2095340002: BUSH and 2093340007: BRACKET simultaneously. Worn bushings cause misalignment that will rapidly degrade the new disc.

Q: Is this part compatible with ZF 6WG-200 transmissions?
A: Yes, the 0630.100.495 disc is compatible with 6WG-200 series, but always verify the clutch pack stack height using a ZF service manual to ensure proper hydraulic clearance.
