ZF 2098.247.021 TUBE | OEM Genuine Part

Overview

The ZF 2098.247.021 TUBE is a precision-engineered fluid conduit designed for the hydraulic and lubrication circuits within ZF heavy-duty construction machinery transmissions. This OEM genuine part, identified by SKU 2098.247.021, serves as a critical pressure line that directs transmission oil to the clutch packs and torque converter. It is typically mounted along the lower valve body or main casing, ensuring a sealed path for high-pressure fluid. When installed correctly alongside the 2098117002 HOUSING, it maintains the structural integrity of the oil gallery system.

Symptoms of Failure

• External oil seepage near the transmission bell housing: A cracked or corroded ZF 2098.247.021 TUBE often causes visible fluid drips, especially after the machine has been parked overnight.
• Intermittent gear slipping under load: When the tube loses its pressure seal, the clutch packs receive insufficient hydraulic force, leading to delayed engagement or slipping in forward gears.
• Overheating transmission fluid: A restricted or collapsed tube restricts oil flow, causing the torque converter to run hotter than normal and triggering warning lights on the dash.
• Erratic shifting patterns: Air ingress through a damaged tube creates aeration in the hydraulic circuit, resulting in harsh or delayed shifts during operation.

Technical Specifications

Compatibility

This tube is engineered for ZF power shift transmissions commonly found in wheel loaders, graders, and telehandlers. It is a direct fit for the WG180 and WG200 series, as well as the 4WG-200 and 6WG-200 variants. The part also integrates with the 2098301052 REAR AXLE HOUS. in articulated dump trucks. For proper installation, use the 0636103300 STUD and secure it with the 0637101164 HEXAGON NUT to prevent vibration loosening.
