When Is the 1000/2000-Hour Service Due?

Scheduled maintenance keeps the engine, fuel, hydraulic and air systems clean. A 1000/2000-hour service calls for fresh filters at those intervals. Typical Bobcat schedules change the engine oil and filter first, then the fuel and hydraulic filters at 500 hours, with a larger service at 1000 hours that adds air filter and fuel/water separator checks. A maintenance filter kit bundles the parts for that interval into one order, which is more convenient than buying each filter separately. Always follow the operator manual for the intervals of your model.

Signs the Filters or Parts Need Replacing

  • Engine oil filter: change it with every oil service; a clogged filter lets oil bypass unfiltered and shortens engine life.
  • Fuel filter and water separator: hard starting, loss of power or water in the separator bowl mean the filter is due.
  • Hydraulic filters: sluggish hydraulics, a restriction warning or hot hydraulic oil point to a loaded filter.
  • Air filters: black smoke, weak power or a restriction indicator tell you the air filter is clogged.
  • Breather or hydraulic cap: a cracked or clogged cap lets dirt in and pressure out.

These symptoms overlap with other fuel, hydraulic and air system problems, so check the basics first.

How to Order and Install the 7403973 1000/2000-Hour Maintenance Filter Kit

  • Confirm your machine model, engine and the part number of the kit before ordering; filter styles differ between model series and serial ranges.
  • Compare the kit contents with your current filters (for example spin-on or cartridge hydraulic filters) before ordering.
  • Replace all filters in the kit at the same time, using the oil and fluid grades listed in the operator manual.
  • Bleed air from the fuel system after changing the fuel filter, and run the engine to check for leaks.
  • Dispose of used filters and oil according to local regulations.
