ZF 4699.199.039 LOOSE PARTS | OEM Genuine Part

Overview

The ZF 4699.199.039 LOOSE PARTS assembly is a critical service kit designed for the internal lubrication and sealing circuits within heavy-duty ZF construction machinery transmissions. This OEM genuine part, identified by SKU 4699.199.039, functions as a collection of loose components—including specific spacers, pins, and sealing elements—that secure the main housing interfaces against pressure loss. It sits directly between the main gear case and the clutch drum assembly, ensuring that hydraulic fluid is directed precisely to the rotating clutches without cross-contamination. When replacing this kit, technicians often pair it with the 4699101043: HOUSING to guarantee a sealed fit, and the 4699301106: HOUSING to maintain structural alignment in the upper valve body area.

Symptoms of Failure

• Intermittent gear slipping under load: When the 4699.199.039 loose parts wear, internal clearances increase, causing clutch packs to lose hydraulic pressure and slip during heavy excavation cycles.
• External oil seepage at the bell housing joint: Degraded sealing surfaces within this kit allow transmission fluid to weep past the 4699301015: HOUSING COVER, leaving visible drips on the chassis.
• Erratic shift timing or delayed engagement: Worn pins or spacers disrupt the precise oil gallery routing, leading to slow clutch fill times and harsh engagement in forward gears.
• Metallic debris in the oil pan: As the loose parts fracture, small metal particles circulate through the system, often damaging the 4699301085: COVER and requiring a full flush.

Technical Specifications

Compatibility

This genuine ZF 4699.199.039 loose parts kit is engineered for use in the WG180, WG200, and WG211 series transmissions commonly found in wheel loaders, graders, and telescopic handlers. It also fits select iterations of the 4WG-310 and 6WG-260 power shift models where the internal loose parts cage requires renewal. Always verify your transmission serial number against the OEM parts catalog before installation.
