ZF 5838.300.513 LUBRICATION TUBE | OEM Genuine Part

Overview

The ZF 5838.300.513 LUBRICATION TUBE is a precision-engineered fluid conduit designed to direct pressurized oil to critical bearing and gear interfaces within heavy-duty ZF construction machinery transmissions. This OEM genuine part ensures consistent lubrication flow, reducing friction and heat buildup during high-torque operations. The SKU 5838.300.513 is positioned within the transmission’s internal oil gallery, connecting the pump output to the differential and axle assemblies. Without this tube, oil starvation can rapidly degrade internal components, leading to costly downtime.

Symptoms of Failure

• Visible oil leaks around the transmission housing – A cracked or corroded lubrication tube often causes drips or puddles beneath the vehicle, especially after prolonged operation.
• Gear slipping or delayed engagement – Insufficient oil pressure due to a blocked or damaged tube leads to erratic shifting and clutch chatter.
• Overheating transmission fluid – Restricted oil flow from a failing tube prevents proper heat dissipation, triggering warning lights or burnt fluid odor.
• Unusual whining or grinding noises – Metal-to-metal contact from oil starvation produces distinct high-pitched sounds during acceleration or turning.

Technical Specifications

Compatibility

This lubrication tube is primarily designed for ZF WG180, WG200, and WG310 series powershift transmissions used in wheel loaders, graders, and dozers. It also fits select ZF 4WG-200 and 6WG-200 variants. Always verify your transmission model and serial number before ordering. The tube interfaces directly with the DIFFERENTIAL HOUSING and works in tandem with the DIFFERENTIAL assembly to ensure even oil distribution.

Frequently Asked Questions

Q: Can I reuse the old sealing washers when installing this tube?
A: No. Always replace copper or aluminum sealing washers to prevent leaks. The tube’s sealing surfaces require fresh gaskets for proper compression.

Q: How often should the lubrication tube be inspected?
A: Inspect during every major transmission service (every 2,000 hours or 12 months). Look for corrosion, cracks, or bent sections that could restrict flow.

Q: Is this tube compatible with synthetic transmission oils?
A: Yes. The zinc-nickel coating resists chemical degradation from synthetic and mineral-based oils rated for ZF TE-ML 03 or 05 specifications.
