Overview
This OEM genuine ZF 0730.006.047 SHIM is a precision-engineered component designed for the WG160, WG200, and related series of heavy-duty transmissions. Positioned within the planetary gearset or clutch pack assembly, this shim establishes the critical axial clearance necessary for proper gear engagement and hydraulic pressure regulation. The SKU 0730.006.047 is manufactured to exacting ZF tolerances, ensuring that the end-play between rotating and stationary elements remains within factory specifications. When installed correctly, this shim prevents metal-on-metal contact and maintains the precise stack height required for smooth power flow through the transmission.
Symptoms of Failure
- Delayed or harsh gear engagement: A worn or collapsed 0730.006.047 shim alters the clutch pack clearance, causing noticeable hesitation or a jarring shift when the transmission engages from neutral into drive or reverse.
- Intermittent gear slipping under load: As the shim loses its original thickness, the hydraulic pistons cannot fully compress the clutch discs, leading to momentary power loss during uphill climbs or heavy hauling.
- Low-frequency driveline vibration: Excessive axial play from a degraded shim allows the gearset to wobble, transmitting a rhythmic vibration through the chassis that intensifies at specific RPM ranges.
- Internal metallic debris in the oil pan: When the shim fractures, small steel particles circulate through the hydraulic system, often found during routine oil changes or filter inspections.

Compatibility
This shim is engineered for the ZF WG series of powershift transmissions. It is a direct fit for the WG160, WG190, WG200, and WG210 models. It also applies to the WG180 variant where the clutch pack stack height requires a 0.50 mm shim. Always verify the current clearance in your specific transmission assembly before final installation, as multiple shims may be stacked to achieve the correct end-play.

When rebuilding the clutch pack or planetary assembly, always inspect the mating surfaces of the CONSOLE and CONSOLE for wear. The HEXAGON SCREW and WASHER should be replaced concurrently to maintain correct clamping force on the shim stack.
Frequently Asked Questions
Q: Can I reuse the 0730.006.047 shim if it looks undamaged?
A: ZF recommends always installing a new shim during any clutch pack or planetary overhaul. Even if the shim appears flat, it may have work-hardened or suffered microscopic compression that will alter the clearance after a few hundred operating hours.
Q: How do I measure the correct shim thickness for my WG200?
A: Use a dial indicator to measure the end-play of the gearset or clutch pack without any shim installed. Subtract the desired clearance (typically 0.10–0.25 mm for most WG series packs) from that measurement to determine the required shim thickness. The 0730.006.047 provides a 0.50 mm starting point.
Q: Is this shim compatible with the WG180 transmission?
A: Yes, the WG180 uses the same planetary carrier and clutch pack dimensions as the WG160 and WG200 series. However, always cross-reference your transmission serial number with the ZF parts catalog to confirm the stack height requirements, as some early WG180 units used a different clutch disc count.
