  • Application: Sight glass gauge group for the hydraulic oil tank

  • Condition: Aftermarket replacement part

Common Use Case or Symptoms:

Use when the hydraulic tank sight glass is fogged, cracked, yellowed or weeping oil so the level cannot be read on a Cat 320C, 330C or 307C.

Why Choose Broken Tractor:

  • ✅ Read your oil level again — A clear sight gauge is a five-minute fix on 29 Cat excavators.
  • ✅ Sister gauges named — Two other sight gauges overlap these models — we list them so you match the right body.
  • ✅ ready to ship from our U.S. warehouses — Louisiana and Ohio.
