The boom cylinder plays a crucial role in excavator performance — but it's also prone to wear and failure. Even a minor issue can lead to costly downtime and project delays.
Over time, the cylinder barrel may develop cracks or wear due to contamination, while the rod can be damaged by debris or excessive lifting beyond machine capacity.
If you need a replacement, Glparts is your trusted source. We offer both brand-new and refurbished boom cylinders, along with repair kits, compatible with major excavator brands like John Deere, CAT, Hitachi, Komatsu, Kobelco, Volvo, and more.
