6406-000 is an aftermarket shaft-end seal kit reference for Danfoss Char-Lynn 10000 Series hydraulic motors. Repair information specifies it as the shaft seal kit, distinct from 6405-000, the motor/body seal kit. It services the drive-shaft end on compatible standard and wheel motors, not bearingless versions. Published references cover 119-xxxx and 120-xxxx motor families with -002, -003, or -004 designs. Confirm the full motor code, shaft configuration, and housing version before ordering. Ruijueparts supports part-number quotation and replacement-part sourcing.

Q1: What is 6406-000 used for?
A: It is a shaft-end, also called front, seal kit for compatible Danfoss Char-Lynn 10000 Series hydraulic motors. It reseals the drive-shaft end of the motor.
Q2: Is 6406-000 the same as 6405-000?
A: No. 6406-000 is the shaft/front seal kit. 6405-000 is the motor/body, often called rear, seal kit. They service different sealing locations and should not be treated as interchangeable.
Q3: Does 6406-000 fit bearingless 10000 Series motors?
A: No. Published service information lists 6406-000 for compatible standard and wheel-motor versions. Bearingless motor configurations require a separate service reference.
Q4: Which motor information should I provide for verification?
A: Send the complete 119-xxxx or 120-xxxx motor code, including the final design suffix, plus a photo of the data plate when available. This confirms the shaft configuration and correct service kit.

OEM seal kits are the right choice when machinery is under active warranty, operating at peak duty cycles, or when failure risk is unacceptably high. Budget aftermarket—like Ruijue Parts—makes sense in these common scenarios:
When a machine is aging out of your fleet, OEM parts cost more than the job warrants. A budget kit extends service life without over-investing.
For machines used infrequently or on lower-intensity tasks, premium OEM pricing may not be justified.
When OEM stock is out or delivery takes weeks, an available aftermarket kit gets your machine running now.
Repair shops and fleet managers running high volumes of machines often balance OEM and aftermarket across their portfolio based on criticality.
Fully retract the cylinder and relieve system pressure before disassembly. Never work on a pressurized circuit.
Remove from the machine. Unthread the gland nut and withdraw the piston rod carefully to avoid surface damage.
Clean the bore, rod, and all metal parts with a lint-free cloth. Contamination introduced during reassembly accelerates seal wear—this step is especially important for budget-grade seals.
Check for scoring or pitting. Budget seals are more sensitive to surface imperfections—address rod damage before fitting new seals.
Lightly coat each seal with clean hydraulic fluid before installation. Use proper seal drivers — not screwdrivers or sharp tools — to avoid nicking the sealing lip.
Torque the gland nut to spec and cycle the hydraulic system under no-load conditions. Inspect for leaks before returning the machine to service.
Budget-grade seals may have shorter service intervals than OEM. Inspect rod seals for moisture, oil film, or weeping more frequently and replace proactively.
Contaminated fluid degrades seals faster — this applies especially to non-OEM materials. Replace fluid and filters on schedule.
When storing equipment with cylinders extended, protect rod surfaces from corrosion and debris to preserve wiper seal life.
Avoid using sharp tools during assembly to prevent nicks or scores on the seal lips. Pre-lubricating all components with clean hydraulic oil is recommended to ensure a smooth fit into the cylinder grooves.
