FRAME GP 4422555 - Caterpillar

Do not permit the cleaning solution to enter the sight glass when soaking the meters.The sight glass may become discolored.Stand the meter assembly on end with the sight glass on top, then fill the meter only, with the cleaning solution.
7. After soaking, repeat Steps 1 through 5 to check and prepare the meter for storage. If the turbine is still stuck, repeat this procedure until the turbine turns freely.8. Always spray the meter turbine with 1U5499 Lubricant, or other approved solvent, then replace both end caps before storing the meter.Checking the Accumulator on the Flowmeter Groups
The 1U5295 Accumulator, mounted on the fuel flowmeter groups, works as a pulse dampener to remove pressure pulses that may be present in the engine fuel lines.Inside the accumulator is a special bladder that is resistant to diesel fuel.This bladder should have no pressure or vacuum in it when the flowmeters are not installed.If the pressure in the accumulator is not correct, the flowmeters may give inaccurate readings.Although there is no pressure in the bladder, it should have the pressure relieved to test it and give it the proper charge.This should be done at least once every 12 months. 1. Remove screw (1) from the end of the accumulator.2. With a small screwdriver, press the valve stem in the end of the accumulator to relieve all pressure.3. Replace screw (1).Setting the Monitor Turn-ON Select Switches
It is desirable to have the 8T9300 Monitor ready to read after power is applied.Three switches inside the monitor can be used to automatically select either one or two meter operation, every time power is applied to the monitor.Fuel temperature will be displayed in either Centigrade or Fahrenheit and fuel information will be displayed in either Liters or Gallons.Once these switches are set, the monitor will always be in the selected operational mode when power is applied.Use the following procedure to set the switches.1. Disconnect all cables from the monitor. Remove the rear cover from the monitor. 2. Locate the small square block that has three slide switches (1). This block is located in the lower right corner of the top printed circuit board. To change the operational mode, move the small sliders to the desired letter that represents the functions. The letters are located next to the switch on the printed circuit board.3. Use the top switch (the one closest to the connector panel) to select L for Liters, or G for Gallons4. Use the center switch to select °C for Centigrade, or °F for Fahrenheit for fuel temperature.5. Use the bottom switch (one nearest the edge of the printed circuit board) to select 2M for two meter operation, or 1M for one meter operation.6. After moving the switches to the desired positions, install the rear cover on the monitor.Fuel Filter Housing Identification (Early Model D300 Family Engines)
Some early model D300 Engines have a fuel filter housing with a fuel flow rate of more than 265 lph (70 gph).This will make it necessary to either use the 1U5440
