What parts are included and what do they do?

The package contains filters and small components that protect distinct systems: intake air, engine lubrication, hydraulic circuits and fuel delivery. Each item reduces contaminants that accelerate wear or reduce performance.

• Outer air filter (part numbers: 7286322, 7221933) — removes large dust and debris before air reaches the engine
• Inner air filter (part number: 7221934) — provides fine filtration for the final intake stage
• Engine oil filter (part numbers: 7343102, 7012303) — traps metal particles and soot to protect bearings and cylinders
• Spin-on charge cooling fan filter (part numbers: 6686926, 7319444) — filters cooling air for charge-air circuits
• Hydraulic oil tank vent cap (part number: 6727475) — prevents contaminants from entering the reservoir while venting
• Hydraulic oil filters (part numbers: 7024037, 6692337) — remove particles and protect valves and pumps
• Fuel water separator (part numbers: 7023589, 7400454) — separates water from diesel to protect injectors and pumps

How does installing this kit benefit my maintenance routine?

Replacing worn filters with matched, OEM-equivalent components reduces the likelihood of premature component failure and can simplify scheduled servicing. Using a single, complete kit saves time sourcing parts and ensures the right combination of filters are installed together.

• Minimizes downtime by bundling all common service items in one order
• Helps maintain engine and hydraulic system performance under heavy use
• Reduces the risk of contamination-related repairs when changed on schedule
• Easy installation with no modifications required when matched to proper models

Who is this kit for? This zuverlass service set is aimed at owners, fleet managers and technicians who maintain Bobcat T- and S-series compact loaders and want a ready-to-install, OEM-equivalent collection of filters. It suits businesses that perform routine preventive maintenance on-site, repair shops handling multiple machines, and operators who prefer to stock a full service kit for scheduled intervals. Before purchase, confirm the listed part numbers against your machine’s current filter numbers or the operator’s parts manual to ensure precise fitment.
