• Apollo Gold – 100-3055 Control Group Temp Sensor

• 100-3055 Control Group
• 100-3055 temperature sensors used on 785Bs and 992Gs
• On 785B – 8 used – aftercooler / brake oil / differential oil / torque converter oil
• On 992G – 3 used – front and rear axle oil / torque converter oil
• Reasons for changing sensor

• Erratic feedback from sensor to VIMS Module
• Temperature reading error
• Sensor unable to calibrate
• Sensor leaking at wire end
• Wires or connections failing

• Costs

• 100-3055 sensor @ $100.00
• Consumption at F.C.M.I. in 2002 was about 25
• One year usage = $2,500
• Over the last 7 years / $17,500

• Failure Analysis

• Probable cause of most failures – seal around the temp probe extruded or

Cut during assembly allowing oil and pressure to enter sensor

• Conclusions
• This was discovered in December of 2002
• Since then 90% of all the sensors changed out have had this fault
• 3 of every 4 new sensors from Cat have this problem
• 50% of all warranty replacements are also faulty.
