Overview
The ZF 5838.300.300 TYPE PLATE is a critical identification and sealing component mounted directly on the transmission housing of heavy-duty construction machinery. This OEM genuine part serves as the primary reference for service technicians, ensuring that the correct assembly specifications and torque values are applied during rebuilds or repairs. The 5838.300.300 plate is laser-etched with ZF’s proprietary part number and serialization, which is essential for verifying the exact transmission variant during overhaul. It sits flush against the main casing, often adjacent to the 5838300626: DIFFERENTIAL HOUSING, and must be replaced whenever the housing is swapped or the plate becomes illegible. Without this plate, identifying the correct internal components—such as the 5838109012: DIFFERENTIAL or the 0750117075: TAPER ROLLER BEARING—becomes guesswork, leading to costly mismatches.
Symptoms of Failure
- Illegible or worn identification markings – When the plate is corroded, scratched, or faded, technicians cannot confirm the transmission model, leading to incorrect part ordering for the 2093209023: DIFFERENTIAL assembly.
- Oil seepage around the plate perimeter – A warped or cracked type plate breaks the housing seal, allowing transmission fluid to weep out, which contaminates the clutch packs and bearings.
- Vibration or loose mounting – If the retaining screws back out, the plate rattles against the housing, eventually shearing the fasteners and risking internal debris contamination.
- Misdiagnosis during service – A missing or swapped plate causes mechanics to apply wrong torque specs, resulting in premature gear slipping or differential failure.

Compatibility
This type plate is designed for ZF’s WG series powershift transmissions commonly found in wheel loaders, graders, and dump trucks. It is a direct fit for the WG180, WG200, and WG211 models. The plate also appears on certain 4WG-200 and 5WG-200 variants used in Caterpillar, Volvo, and Komatsu equipment. Always cross-reference your transmission serial number with the plate etching to ensure compatibility with the 5838300626: DIFFERENTIAL HOUSING and the 5838109012: DIFFERENTIAL.

Frequently Asked Questions
Q: Can I reuse the old type plate if it is still readable?
A: No. ZF recommends replacing the 5838.300.300 plate whenever the differential housing is removed, as the adhesive backing and sealing gasket degrade over time. A reused plate often causes oil leaks.
Q: Does this plate include the mounting screws?
A: The plate itself is the etched metal tag only. You will need to order M6 bolts separately. We recommend pairing it with the 0631329088: SPRING PIN for proper alignment.
Q: Will this fit a ZF 4WG-310 transmission?
A: No. The 5838.300.300 is specifically for WG180, WG200, and WG211 models. For 4WG-310, use the larger type plate (part 5838.300.400).
