ZF 4657.231.017 OIL DIPSTICK for WG210 | OEM Genuine Part

Overview

The ZF 4657.231.017 OIL DIPSTICK is a precision-machined diagnostic component designed exclusively for the WG210 series transmission. This genuine OEM part allows operators to verify correct fluid levels within the main sump, ensuring the hydraulic system maintains proper pressure and lubrication. The dipstick integrates directly into the TRANSMISSION HOUSING and provides a sealed interface to prevent contamination ingress. The SKU 4657.231.017 is manufactured to ZF’s exacting tolerances, featuring a graduated rod that corresponds to specific thermal expansion ranges for the WG210’s oil circuit.

Symptoms of Failure

• Transmission fluid seepage at the dipstick tube seal – A worn O-ring or cracked handle on the 4657.231.017 allows ATF to weep past the insertion point, leaving visible drips on the bell housing.
• Inaccurate oil level readings leading to gear slippage – When the dipstick’s measurement marks become corroded or the rod bends, operators overfill or underfill the sump, causing clutch pack chatter and delayed engagement.
• Hard shifting during cold starts – A broken dipstick seal permits air ingestion into the hydraulic circuit, aerating the oil and reducing line pressure, which manifests as harsh 1-2 upshifts.
• Visible cracking or brittleness on the handle – Thermal cycling degrades the polymer grip, causing the dipstick to snap during routine inspection, leaving fragments inside the HOUS.FRONT SECT.

Technical Specifications

Compatibility

This dipstick is engineered for the ZF WG210 series, but cross-referencing with the HOUSING REAR PART dimensions confirms it also fits WG180, WG200, and WG250 models that share the same oil pan depth and tube boss geometry. The 4657.231.017 is not compatible with older WG120 or WG150 units that use a shorter dipstick tube. Always verify the CYLINDRICAL PIN alignment in the housing bore before installation to avoid cross-threading the retaining clip.
