Can a bent hydraulic cylinder rod be fixed?
A: Yes, most bent hydraulic rods can be straightened using a high-tonnage hydraulic press and precision measuring tools. If the rod is bent beyond the safety limit or the chrome is cracked, Sterig can machine a custom replacement rod in-house using induction-hardened chrome material to get your machine back in service without the long lead times of OEM ordering.
Q: How long does a hydraulic pump or motor rebuild take?
A: A standard hydraulic pump rebuild typically takes 2 to 5 business days, depending on parts availability. However, for critical "machine down" situations in the Chicago and Lake Barrington areas, Sterig Hydraulic Repair Inc. offers expedited service to minimize downtime for construction and scrap metal operations.
Q: Why is my excavator cylinder leaking after a seal change?
A: If a cylinder leaks shortly after a seal change, the issue is likely barrel scoring or a nicked rod. Even microscopic scratches can shred new seals. At Sterig, we use precision honing to smooth the internal barrel surface and inspect rods for "pitting" to ensure a leak-free seal that lasts.
Q: Is it better to repair or replace a hydraulic cylinder?
A: In 90% of cases, repairing a hydraulic cylinder is more cost-effective than replacement. A professional rebuild at Sterig Hydraulic Repair Inc. typically costs 40-60% less than a new OEM unit. Rebuilding also allows for custom upgrades, such as high-performance seals and precision honing, which can make the repaired cylinder more durable than the original.
