Q: What JCB models use the 991/00130 hydraulic seal kit?
A: The 991/00130 (also referenced as 99100130 or 991-00130) is a hydraulic seal kit designed for specific JCB backhoe loader and excavator cylinders, commonly used in boom, dipper, or stabilizer applications depending on machine configuration. Seal kit compatibility can vary by cylinder serial number and production year. Always verify this part number against your machine's parts manual or the cylinder's original seal kit reference before ordering.
Q: What are the symptoms of failing hydraulic cylinder seals on JCB equipment?
A: Common symptoms include visible hydraulic oil leaking from the cylinder rod or gland area, decreased lifting or digging force, cylinder drift where the implement slowly lowers under load, jerky or erratic cylinder movement, and external oil contamination around the cylinder assembly. Early seal replacement helps prevent internal cylinder scoring and more expensive repairs.
Q: What is included in the COGENG 991/00130 seal kit?
A: Each complete seal kit includes piston seals, rod seals, wiper seals, O-rings, backup rings, and gland seals required for a full cylinder overhaul. COGENG kits are manufactured using materials that meet or exceed OEM specifications for abrasion resistance, temperature tolerance, and extended service life.
