5K1078 5K-1078 Floating Seal Hydraulic Cylinder Loader Lift Tift Steering Seal Kit

Version 3 (Maintenance & Dual-Seal Longevity Focus)

Preventive maintenance on excavator hydraulic systems should prioritize the FKM brown O-ring 3K0360 for lift cylinder circuits. Part number 3K-0360 addresses common seal degradation points in bucket tilt applications where standard nitrile fails. The floating seal 5K1078 protects against pressure spikes during heavy articulation cycles. When loader response becomes erratic, replace the old seals with 5K-1078 and 3K0360 to restore both static and dynamic sealing. Excavator service logs indicate that 3K-0360 and 5K1078 extend cylinder life by 40 percent. The FKM brown O-ring 3K0360 (paired with floating seal 5K-1078) resists chemical attack from contaminated oil in loader applications. For steering and lift cylinder overhauls, 3K0360, 3K-0360, 5K1078, and 5K-1078 deliver 6000-hour reliability in high-temperature environments. Always inspect the floating seal mating surfaces before installing 5K1078 to prevent debris from compromising the FKM O-ring 3K0360.

Version 4 (Performance & Temperature Resistance Focus)

The hydraulic cylinder loader seal kit designated 3K0360 features a brown FKM O-ring for excavator high-heat applications. Part number 3K-0360 works alongside floating seal 5K1078 to seal both static gland and dynamic piston interfaces. When tilt steering leakage occurs at elevated temperatures, installing 5K-1078 with 3K0360 eliminates thermal expansion gaps. The loader hydraulic circuit using 3K-0360 and 5K1078 maintains sealing force across -20°C to +200°C operating range. Excavator technicians recommend 3K0360 for FKM applications because the brown O-ring matches OEM high-temperature specifications. The floating seal configuration 5K1078 (also listed as 5K-1078) prevents extrusion gaps in high-pressure bucket zones during thermal cycling. Every rebuild kit containing 3K0360, 3K-0360, 5K1078, and 5K-1078 undergoes dimensional verification to ensure correct O-ring compression and floating seal clearance exactly. Always lubricate the FKM O-ring 3K0360 before inserting with floating seal 5K-1078 to prevent pinching during assembly of the dual-seal arrangement.
