Compress it to the same length it is actually compressed in the engine. Remove the glow plugs 1. Based upon the conventional model, Kubota developed a unique governor system and various new mechanisms which reduces exhaust emission, noise and vibration and realize durability and high torque. Clean the crankpin and crankpin bearing. If the clearance exceeds allowable limit, replace the ring.
Molybdenum disulfide MoS The molybdenum disulfied serves as a solid lubricant, like a Graphite or Teflon. Place the valve spring on a tester. To check the oil level, draw out the dipstick 1 , wipe it clean, reinsert it, and draw it out again. Measure the resistance across the slip rings with an ohmmeter. If the clearance exceeds the allowable limit, replace the oil pump rotor assembly. Start and warm up the engine for approx. Take out the element 4 and dip it in the kerosene to rinse.
If the measurement is less than the allowable limit, replace the spring. If the resistance is infinity, the intake air heater is faulty. While the temperature of coolant in the engine is low, the thermostat is held closed and the coolant is allowed to flow through the bypass pipe and to circulate in the engine. Tappet to Tappet Guide Clearance 0. Thus, this engine achieves high combustion efficiency and complies with various regulations of exhaust gas.
Check the coolant temperature and monitor the coolant temperature while checking 1 and 2. Slowly move the tester handle to measure the pressure at which fuel begins jetting out from the nozzle. If the pressure can not reach the allowable limit, replace the pump with new one or repair at a Kubota-authorized pump service shop. Measure the deflection A , depressing the belt halfway between the fan drive pulley and alternator pulley at specified force 98 N 10 kgf, 22 lbf. Optional type has 1 idle gear. Remove the connecting rod caps. Make sure the notch mark a , b or c of cylinder head gasket 1 in advance.
Keep open sparks and flames away from the battery at all times, especially when charging the battery. Set the timer 0 ° restoring jig 4 to the timer gear 3. Pull out the fuel camshaft and bearings 7 together from the injection pump housing. Slowly move the tester handle to measure the pressure at which fuel begins jetting out from the nozzle. Read the compression load on the gauge. Disconnect the governor lubricating pipe 6.
Set the timer 0 ° restoring jig 5 to the timer gear 4. If the level is below than lower level line 2 , and the distilled water to pour level of each cell. Check the specific gravity of the electrolyte in each cell with a hydrometer. John Deere® and all of the John Deere® engine models listed on this website are registered trademarks of John Deere. Remove the timer gear lubricating pipe 1. Remove the over flow pipe 3.
Remove the nozzle holder 1 , and take out parts inside. Unscrew the retaining ring 6 and remove the filter cup 5 , and rinse the inside with kerosene. Measure the cylinder block bore I. Remove the fan belt 1. Remove the governor lever assembly 4 from the governor housing. Remove the piston pin from the piston.
Set a dial indicator with its tip on the idle gear. Remove the gear case cover 2. Apply engine oil to a new valve guide. If you do not replace piston, piston pin bush, connecting rod, crankpin bearings, or crank journal bearings, replace the same notch mark a , b or c as the original cylinder head gasket 1. The output of the control unit is a pulse width modulated signal to the proportional solenoid.
Heavy duty, reliable and exceptionally powerful, the V3800 offers the added benefit of being exceptionally easy to maintain with a long service life. Remove the thermo valve 3. Measure the valve stem O. Check the battery electrolyte level. Place the thermostat and a thermostat in a container with water and gradually heat the water. Set the injection nozzle to the nozzle tester. Set the stopper to the flywheel.
Set the speed control lever to the maximum speed position. When reassembling 255 to 274 N·m Tightening torque Crankshaft screw 26. Disconnect the battery positive cable from the battery. Remove the relief valve 2 , the spring 3 and the packing 4. Remove the air cleaner and muffler. Move the stop lever 6 and visually check to see if the fuel injection pump control rack comes smoothly back to the start position by the counter force of the start spring.
