Installation Notes / Recommendations:
-
Before installation, thoroughly clean cylinder components (rod, tube interior, head/gland) to remove debris, old seal remnants and scoring.
-
Inspect rod surface for nicks, scratches or corrosion and repair or replace if necessary — damaged rods will prematurely wear new seals.
-
Use correct hydraulic fluid to lubricate seals during installation to avoid damage.
-
Install in correct sequence (e.g., wear ring, backup ring, piston seal, O-ring) and ensure correct orientation of each component.
-
After installation, bleed the hydraulic system, perform leak checks, and verify correct cylinder operation under load.
Tips:
-
Match the kit specifically to your model and cylinder type (boom, arm or bucket) to avoid fitment issues.
-
Inspect your cylinder rod & barrel for damage — replacing seals alone won’t fix underlying mechanical wear.
-
Consider keeping a spare kit and extra seals if your machine sees heavy use — downtime savings can be substantial.
-
Use proper installation tools and practice good hygiene (clean working area, remove contaminants) to avoid seal damage.
-
Record the installation date & seal kit used in your maintenance log so you can track performance and replacement intervals.
