Challenger 75D (5AR),
Challenger 85D (4GR) Agricultural Tractors
Description of Change: A retrofit is available for an improved primary fuel filter group in the above Challenger Agricultural Tractors powered by 3176/3176B Machine Engines. The improved primary fuel filter group includes a water separator and filter group that helps prevent the secondary fuel filter assembly from becoming plugged, increasing the life of the secondary filter.
Adaptable To: The improved 136-4552 Primary Fuel Filter Group is available for retrofit. The improved 136-4552 Fuel Filter Group is effective with Challenger 75D (5AR1) and Challenger 85D (4GR1) Agricultural Tractors and adaptable to Challenger 75 (4CJ446-Up), Challenger 75C (4KK1-Up), Challenger 85C (9TK1-Up), Challenger 75D (5AR1-Up), and Challenger 85D (4GR1-Up) Agricultural Tractors. See the following chart for parts required.
