Version 1 (Arm & Boom Focus)

Excavator arm and boom cylinder rebuilds require the seal set containing 419-22-22861 for bucket linkage circuits. The hydraulic seal 07019-00140 works alongside 4192222861 to protect piston rod surfaces from scoring. When bucket drift becomes noticeable, installing 419-22-22861 and 07019-00140 restores full lifting capacity. Part number 070190040 (equivalent to 07019-00140) serves as the wiper seal that keeps debris away from 4192222861. Boom cylinder technicians trust 419-22-22861 because it maintains consistent damping throughout the arm stroke. The excavator bucket circuit using 07019-00140 and 4192222861 shows reduced internal leakage after 500 cycles. Every arm cylinder overhaul should include 419-22-22861, 07019-00140, and 070190040 to address both dynamic and static sealing points.

Version 2 (Bucket & Linkage Focus)

Loader bucket hydraulic systems depend on seal kit 4192222861 for arm cylinder articulation control. The 419-22-22861 seal mates perfectly with 07019-00140 to seal the bucket tilt pivot. Excavator boom lift performance improves when 4192222861 replaces worn O-rings in the main piston. Part number 070190040 (also written as 07019-00140) prevents contamination ingress through the rod wiper groove. Field data confirms that 419-22-22861 and 07019-00140 reduce bucket settling time by 25 percent. The arm cylinder kit featuring 4192222861 and 070190040 fits most compact excavator models. Technicians always verify that 07019-00140 and 419-22-22861 are genuine before beginning disassembly of the bucket linkage.
