ZF 4061.313.115 PRESSURE RING for WG200 | OEM Genuine Part

Overview

The ZF 4061.313.115 PRESSURE RING is a precision-engineered component designed for the WG 200 series transmissions. This OEM genuine part functions as a critical sealing and pressure-directing element within the hydraulic control circuit, ensuring consistent clutch engagement and torque converter lock-up. The SKU 4061.313.115 sits directly inside the valve body assembly, where it maintains oil pressure integrity between the 4460115043: HOUSING and the rotating drum assembly. Without this ring, the transmission cannot build the necessary hydraulic pressure for smooth gear shifts.

Symptoms of Failure

When the ZF 4061.313.115 PRESSURE RING wears out, operators typically notice these specific failure modes:

• Delayed engagement when shifting from Neutral to Drive or Reverse – A worn ring allows internal pressure to bleed off, causing a 2-3 second lag before the transmission engages.
• Erratic gear slipping under load – As the ring loses its sealing ability, the transmission may slip during uphill climbs or when carrying heavy payloads.
• Low hydraulic pressure readings at the test port – A cracked or flattened pressure ring will cause pressure drops of 15-25 PSI below specification.
• Oil contamination with metallic debris – Worn ring material can shed particles into the oil, often visible during routine fluid changes.

Technical Specifications

Compatibility

This 4061.313.115 PRESSURE RING is engineered for the ZF WG series transmissions, specifically the WG180, WG200, and WG210 models. It is also compatible with the 4469315012: AXLE DRIVE HOUSING assembly found in off-highway trucks and wheel loaders. For proper installation, always pair this ring with a new 0750117406: TAPER ROLLER BEARING and the 0750117802: TAPERED ROLLER BEARING to ensure correct axial clearance.
