II. Complete Parts List of the Repair Kit

One set includes all seals for a single boom cylinder, eliminating the need for additional oil seal purchases:

Piston rod dust seal (scrapes away dirt and sand from the outer end to prevent impurities from entering the cylinder)

Main piston rod oil seal (prevents oil leakage from the rod body, resolving boom drop and weak lifting)

Two wear-resistant piston rod support rings (protect the piston rod plating and reduce scoring)

Piston bidirectional main seal (a core component for internal cylinder leakage; internal leakage can cause the bucket to drop automatically)

Piston wear-resistant support ring

Cylinder head and end cap O-rings

Buffer dust gaskets
