Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial symptom of a failing bucket cylinder seal kit is a slow or sluggish bucket curl or dump function. If left unaddressed, the cylinder will continue to lose hydraulic pressure, leading to a noticeable loss of digging or dumping power and visible hydraulic fluid leaks. Continued operation risks significant hydraulic system contamination and potential damage to the cylinder bore.
Thoroughly clean the cylinder bore and rod before installing new seals to prevent damage from debris. Ensure the new seals are properly oriented according to the manufacturer's instructions to prevent immediate leakage.
Inspect the cylinder rod for scoring or damage, and clean or replace if necessary, before installing the new seal kit.
