Field Failure & Solution

Model: CAT 336D
Issue: High summer heat aged seals in hydraulic cylinder 4T9364, piston rod scored and internal leakage caused boom lifting weak.
Fix: ① Replaced with Growshine high-pressure seal kit (Polyurethane); ② Honed barrel to Ra≤0.4 µm; ③ Changed to CAT 10W-60 oil; ④ Pressure test 35 MPa 30 min no leak. Machine back to work in 2 hrs, 62 % cheaper than OEM complete cylinder.
