QY55KA-Y Outrigger Cylinder Seal Kit C14
For procurement teams: Tell us which leg and whether the problem is external leakage or pressure loss under load.
Where It Works
An outrigger leak affects stability and job-site confidence. The C14 kit needs to match the exact jack or beam cylinder and the cause of leakage must be removed.
Before You Quote
Failure Pattern and Root Cause
A jack that settles may have piston bypass or a load-holding valve fault. Oil at the gland suggests rod sealing, but scoring or side load may be the real cause.
Installation Outcome to Verify
Support the crane independently, release pressure and clean thoroughly. After rebuilding, bleed air and perform an approved outrigger holding test on level ground.

Questions from Maintenance Teams
Can seals alone stop outrigger settlement?
Only if internal cylinder leakage is confirmed.
Why identify the leg?
Cylinder variants can differ by position.
What is the final test?
Leak-free cycling plus specified holding verification.
C14 seals are grouped by piston/gland location in dust-proof bags.
