Key Notes:

• Part Number: 11383
• Weight: 3 lbs (1.36 kg)
• Teeth: 19-tooth and 22-tooth faces — compound idler gear with two gear faces on a single body
• Application: Transmission reverse compound idler gear — the dual-face idler gear positioned between the forward and reverse drive gear sets in the transmission, transmitting reverse drive through the 19 and 22 tooth faces to achieve reverse travel on Case 310 through 350B series crawler dozers
• Location: Transmission reverse idler gear position — inside the transmission case

Common Use Case or Symptoms: Use when the reverse idler gear has chipped, cracked, or worn teeth, the transmission jumps out of reverse, or grinding noise is present during reverse engagement — a failed reverse idler gear causes loss of reverse drive, transmission noise in reverse, and potential secondary damage to adjacent transmission gears on Case 310 through 350B crawler dozers.
