Product Overview

Difficulty in starting the engine without any exhaust smoke may indicate the Control Rack is stuck in the stop position.
This typically occurs with the Robert Bosch Governor, where the control rack must move towards the rear of the injection pump
to initiate proper functionality. Sticky residue, such as gum and varnish in the fuel, often causes this issue.

Key Features

• Prevents sticking of control rack.
• Enables smooth operation of the injection pump.
• Uses Case Diesel Fuel Conditioner to maintain fuel cleanliness.

Benefits

• Ensures reliable engine start.
• Prevents formation of deposits within the engine.
• Maintains efficiency and prolongs engine lifespan.

Usage Recommendations

• Add a small quantity of “Case Diesel Fuel Conditioner” to the fuel tank daily to clean existing deposits and prevent new ones.
• Refer to the Fuel Specifications Section in the Operator’s Manual for detailed guidelines.

Instructions to Free the Control Rack

To resolve control rack sticking, follow these steps:

• Loosen and remove the cap nut on the front of the injection pump.
• Position the throttle in the wide open state to encourage control rack movement to the full load position.
• Manually work the control rack from the cap nut end several times to alleviate stickiness.
• Ensure the control rack operates smoothly before replacing and tightening the cap nut.
