83A0774 O-ring Liugong CLGB320C bulldozer spare parts

Short Description:

83A0774 O‑ring is sealing fitting for hydraulic and transmission positions of Liugong CLGB320C bulldozer. It fills assembly clearance by rubber elasticity to prevent leakage of hydraulic oil and lubricating oil, and block external sediment and sewage from entering mating pairs. Timely replacement is required when O‑ring becomes hardened, cracked, swollen or permanent compression‑deformed, to avoid pressure relief and leakage failure of system.

=======================================

advantages

Oil‑resistant rubber material, resistant to hydraulic‑oil immersion, low swelling and aging, adapt to temperature fluctuation during continuous bulldozer operation
Cross‑section dimension strictly follows OEM standard with reasonable pre‑compression for stable sealing performance
Good extrusion‑resistance and wear‑resistance, withstand hydraulic‑system pressure fluctuation and site vibration‑shock environment
Stable dimensional accuracy and good assembly compatibility, fit corresponding groove without on‑site cutting or modification.

FAQ

Q: Can O‑ring be reused after disassembly if appearance looks intact?
A: Invisible compression deformation occurs after disassembly. Reuse is not allowed under heavy‑duty mine condition.
Q: Can thicker O‑ring compensate for slightly worn groove?
A: Not allowed. Oversized O‑ring is easy to be sheared and damaged. Repair groove or adopt standard spare parts.
