The stop position on the Robert Bosch Governor is always with the control rack toward the rear of the injection pump or governor. The sticking of the control rack can be due to gum and varnish in the fuel. Instruct the customer to use a small quantity of "Case Diesel Fuel Conditioner" in the fuel tank daily. This will clean out the gum and varnish deposits already in the engine and will prevent these deposits from forming. Refer the customer to the Case Diesel Fuel Conditioner in the Fuel Specifications Section of the Operator's Manual. To free the control rack, proceed as follows: 1. Loosen and remove the cap nut on the front of the injection pump. 2. Place the throttle in the wide open position so the control rack will be toward the full load position. 3. Work the control rack from the cap nut end by hand a few times to relieve the sticking due to the gum and varnish. 4. Make sure the control rack works easily and smoothly before replacing and tightening the cap nut.
