7079858200 7079958080 707-98-58200 707-99-58080 Arm Boom Bucket Hydraulic Cylinder Excavator Seal Kit

For maintenance teams and fleet managers responsible for sustaining the operational efficiency of EXCAVATOR loaders in open-pit mining (ore loading and rock excavation), coastal dredging (sand/silt removal and underwater structure repair), and heavy construction (concrete demolition and steel beam lifting)—where Arm Boom Bucket Hydraulic Cylinder systems confront three critical challenges: heavy debris impact (5–20 kg rocks, steel fragments, and concrete chunks), high-pressure surges (12,000–35,000 psi during rock crushing), and extreme humidity corrosion (85–100% humidity in coastal/marshy areas)—the performance of the hydraulic seal system is non-negotiable. Unlike the 4173698/2405500 series designed for moderate-pressure lift/tilt/steering tasks and fine-particle resistance, the Arm Boom Bucket Hydraulic Cylinder Excavator Seal Kit (part numbers 7079858200, 7079958080, 707-98-58200, 707-99-58080) is engineered to address these arm/boom/bucket-specific stressors. On a daily basis, these systems operate in high-intensity environments: they endure 150+ daily heavy-impact cycles (boom cylinders absorbing rock collisions, bucket cylinders crushing concrete), manage sudden pressure spikes (up to 35,000 psi when the bucket encounters hard bedrock), and resist corrosion from salt-laden humidity (coastal dredging) or marshy moisture (wetland construction)—all while extending arms 8–15 meters (arm cylinders), lifting 20–50 ton loads (boom cylinders), and gripping 10–30 ton materials (bucket cylinders). If seals fail, the EXCAVATOR loader experiences catastrophic issues: arm cylinder leaks causing load droop (risking equipment damage), boom cylinder rupture from pressure surges (halting mining operations), or bucket cylinder corrosion leading to fluid contamination (costing $15,000–$25,000 in cylinder repairs). To avoid such crises, the 7079858200 and 7079958080 seal kits are the ideal solution: they form an impact-resistant, high-pressure-stable, and humidity-corrosion-proof seal that absorbs heavy debris impacts, mitigates pressure spikes, and repels moisture—ensuring reliable performance in mining, coastal dredging, and heavy construction where the 4173698/2405500 series would be underengineered and incompatible with arm/boom/bucket systems.

Accurate part numbers are critical to guarantee compatibility with the Arm Boom Bucket cylinders of EXCAVATOR loaders, as these systems demand robust, high-tensile materials (unlike the 4173698’s low-friction nitrile-PTFE) and pressure-dispersing structures. The 7079858200 (written with a hyphen as 707-98-58200) and 7079958080 (written with a hyphen as 707-99-58080) serve as trusted references for technicians and procurement staff, confirming the seal kit meets precise specifications: seal durometer (90±5 Shore A for impact resistance, compared to 75 Shore A for 4173698’s smooth movement), pressure tolerance range (12,000–35,000 psi, versus 2,500–9,000 psi for 2405500’s lift/tilt systems), and humidity resistance (85–100% RH for 5,000+ hours, unlike the 4173698’s mild 60–75% RH focus). Notably, 707-98-58200 and 707-99-58080 are integrated into global heavy-equipment databases (e.g., Caterpillar Mining Parts Portal, Komatsu Dredging Equipment Catalog), preventing ordering errors common with generic part numbers. If an incorrect seal kit (e.g., 2405500, designed for moderate-pressure lifts) is installed on a mining excavator’s boom cylinder, it will rupture within 40 hours of pressure surges—leading to $20,000 in repair costs and 72 hours of downtime. For example, a coastal dredging company in Southeast Asia (using a Volvo EC750E excavator for sand removal) found that installing 4173698 seals (instead of 7079858200) on the bucket cylinder resulted in catastrophic failure: the low-friction nitrile seals couldn’t resist saltwater humidity, corroding completely within 300 hours and contaminating the hydraulic system—delaying dredging projects by 5 days.
