Q: What specific hydraulic failures indicate that a 320CL boom cylinder requires an immediate workshop seal overhaul?
A: Visible fluid weeping pooling around the cylinder head gland, slow lifting speed under full workload, and an inability to hold the挖臂 section steady at standby.

Q: What preparation standards must re-assembly crews follow before placing a new lift cylinder onto the equipment hinges?
A: Use high-strength lifting straps to hold the housing straight during alignment, thoroughly clean the pin boss surfaces, and pack the spherical bearings with grease.
