DIESEL FUEL
Use NO.2 diesel fuel in the engine ofthis machine. The use of other fuels cancause the loss of engine power and highfuel consumption.
Invery cold temperatures, a mixture ofNO.1and NO.2 diesel fuels is tempora-rily permitted. See the following Note.
NOTE: See your fuel dealer forwinter fuel requirements in your area. Ifthe temperature of the fuel is below thecloud point (wax appearance point), waxcrystals in the fuel will cause the engineto lose power or not start.
The diesel fuel used in this machinemust meet the specifications in the chartbelow or Specification 0975-81 of theAmerican Society for Testing and Mate-rials.
Fuel Storage
If you keep fuel in storage for a periodof time, you can get foreign material orwater in the fuel storage tank. Manyengine problems are caused by water inthe fuel.
Keep the fuel storage tank outsideand keep the fuel as cool as possible.Remove water from the storage con-tainer at regular periods of time.

RUN-IN INSTRUCTIONS
Engine Lubrication
Fill the engine crankcase with CO or CE service classification oil that has the correct viscosity rating for the ambient airtemperature. Install new oil filters, after the engine has been rebuilt.
Run-In Procedure for Rebuilt Engine
Step 1 Disconnect the wire to the electric shut-off on the injection pump so that the engine will not start Crank theengine for 30 seconds until there is oil pressure, then reconnect the wire.
Step 2 Remove the air from the cooling system at the temperature sending unit.
Step 3 Run the engine at 1000 RPM minimum load for 5 minutes and check for oil leaks
Step 4 During the Run-In, continue to check the oil pressure, coolant level, and coolant temperature.
Run-In Procedure for Rebuilt Engines (With a Dynamometer)
The following procedure must be followed when using a PTO dynamometer to Run-In the engine. The dynamometer willcontrol the engine load at each speed and will remove stress on new parts during Run-In.
During the Run-In, continue to check the oil pressure, coolant level and coolant temperature.

Torque converter stall speed 2200 to 2300 rpm (r/rnin)
Combined stall speed 1550 to 1750 rpm (r/min)
GENERAL INFORMATION
Do the stall test to find the cause of poor perfor-mance.
The engine is run at full throttle and the transmissionand hydraulic systems are engaged separately, andthen together.
Comparing the engine speeds from the stall testwith the check sheet on page 2002-4 will help to find thecause of the problem. It can be necessary to check aseparate system to find the exact cause of the problem.
Use a photo tachometer or other tachometer ofequal accuracy to get accurate results from the stalltest.
The engine, transmission and hydraulic systemmust be at operating temperature before doing the stalltest. Heat the oil according to instructions in thissection.
PREPARING THE MACHINE FOR THE STALL TEST
1. See Section 9001 and check the full throttle and lowidle speeds.
2. Apply the parking brake.
3. With the engine running at low idle move the trans-mission control lever to fourth gear and the directioncontrol lever to FORWARD.
Bur 8-12301
4. Slowly increase the engine speed to full throttle.

RUN-IN INSTRUCTIONS
Engine Lubrication
Fill the 4-390 engine crankcase with CC/SF, CD/SF, CE/SF or CF-4 service classification oil. Use the correct viscosityrating for the ambient air temperature. Install new oil filters after the engine is rebuilt.
Fill the 4T390 and the 4TA 390 engine crankcase with CE/SF or CF-4 service classification oil. Use the correct viscosityrating for the ambient air temperature. Install new oil filters after the engine is rebuilt.
Run-In Procedure for Rebuilt Engine
Step 1 Disconnect the wire to the electric shut-off on the injection pump so that the engine will not start. Crank theengine for 30 seconds until there is oil pressure, then reconnect the wire.
Step 2 Remove the air from the cooling system at the temperature sending unit.
Step 3 Run the engine at 1000 RPM minimum load for 5 minutes and check for oil leaks.
Step 4 During the Run-In, continue to check the oil pressure, coolant level, and coolant temperature.
Run-In Procedure for Rebuilt Engines (with a Dynamometer)
The following procedure must be followed when using a PTO dynamometer to Run-In the engine. The dynamometer willcontrol the engine load at each speed and will remove stress on new parts during Run-In.
During the Run-In, continue to check the oil pressure, coolant level and coolant temperature

STEP 48
Check the valves for the following conditions.
VALVE STEM WITH A NARROW NECK
j8902893J
NOTE: REPLACE THE VALVE IF THIS CONDITION OCCURS.
This Condition Can Be Caused By:1. Valve does not have lubrication.2. Restriction in the water passages.3. Operating the engine under continued overload attoo much engine RPM.
._-- GROOVE IN VALVE FACE
8902894J
NOTE: GRIND OR REPLACE VALVE IF THIS CONDITIONOCCURS.
This condition can be caused by foreign materialentering the engine through the intake system or notgiving service to the air intake system.
Rae 8-24173
I FINE PiniNG
8902895J
NOTE: THIS IS A NORMAL CONDITION.
Small amounts of very fine pitting can be found on thesurfaces of the valve face or seat after the valves arecleaned. These are normal and will not change theengine performance. This fine pitting is caused bynormal oxidation procedure and can occur on anyengine during the run-in period. It is not necessary togrind valves or seats if this fine pitting is found. becausepitting will generally occur after the engine has run forseveral hours.
8902896J
NOTE: GRIND OR REPLACE THE VALVE IF THIS CONDITIONOCCURS.
This condition is generally caused by worn valve guidesor bad seals on the valves. permitting oil to go by thevalves. Low operating temperature is a secondarycause. Worn piston rings and cylinder walls will alsopermit too much oil to reach the combustion chamber.
RUST OR PiniNG ON VALVE STEM
18902897J
NOTE: REPLACE VALVE IF THIS CONDITION OCCURS.
This condition can be caused by using bad qualityengine oil or fuel and by not correctly keeping theengine in storage.
Revised 2-92 Printed in U.S.A.
NOTE: THIS CONDITION CAN BE CAUSED BY USING BADQUALITY ENGINE OIL OR FUEL.
DEEP BURNED VALVE FACE
CONCAVE VALVE HEAD
These conditions are generally caused by running theengine at very high engine temperatures, grinding thevalve face too thin or valve grinding that is not correct.
