  1. 9540 Overcharging

    9540 Overcharging

    did you check that you had the correct voltage approx. 14.5 V after changing the regulator. Check the diodes in the generator that regulate the magnetization winding. Hazze

    question Zetor 5340 Fuel hoses diameter?

    I use fuel hose 5 mm inner diameter (3/16) 12 bar. Push on and clamp. I mannage to change behind the pump but am equiped with small hands. Hazze
  3. Gearbox modification kit for Zetor 4340 from 1993

    question Gearbox modification kit for Zetor 4340 from 1993

    Thank you for your reply. My tractor is model 4340 1993. I presume that is the same box as in 5045 and 5245. The design is mor or less the same from 1980 have I been told. Hazze

    Anybody knows where to buy a gearbox modification kit that will prevent the reverse gear to be stucked. Any pictures how it looks? Hazze
  5. Zetor 5340 starting trouble

    question Zetor 5340 starting trouble

    The hose is pressed on the banjo joint. I belive you have to buy a premade hose with the banjos. It might be https://www.atpmotor.cz/en/e-shop/7563-fuel-supply-pipe-i-4320-7340-l-12-12 Please check it up. Hazze
  6. Zetor 5340 starting trouble

    question Zetor 5340 starting trouble

    the pump you have chosen seems to be a pump to be mounted very close to the tank and is a pressure and not a suction pump. check that it really sucks up enough fuel. I have in mind that the regular lifting pump gives about 16 psi but can remember wrong.
  7. Zetor 5340 starting trouble

    question Zetor 5340 starting trouble

    Do not know why the return hose affects the injection pump but was advised by a Finnish specialist on Zetor tractors. Air must not come into the injectionpump the backway espessial if the oneway valve in the pump is not 100%. My electric pump stops when the pressure has built up and only pumps...
  8. Zetor 5340 starting trouble

    question Zetor 5340 starting trouble

    Not sure it will help your problem but replace the return hose from the ejectors back to the injection pump. Difficult to access behind the injection pump but it is possible. Also replace the hoses between the tops of the injectors that connect all four and then go to the injection pump. Has...
  9. Breather pipe leaks oil - Zetor 5340

    question Breather pipe leaks oil - Zetor 5340

    overpressure in the crankcase that can be caused by jammed or broken piston rings. There is a lot to read about this problem in this forum. the reason for jamming piston rings may be that the engine is never really works hard but runs too light. Hazze
  10. Zetor 5340 Breather pipe, Fuel pump, Air compressor

    question Zetor 5340 Breather pipe, Fuel pump, Air compressor

    At 6718 the tank is above the pump level but at 5340 the pump must suck up the fuel from a low level Your problem is that the fuel flows back to the tank due to that air leaks into the system. This is a classic problem on these models. Replace all hoses from the tank as these are originally of...
  11. Air leaking from fuel injector - Zetor 5511

    question Air leaking from fuel injector - Zetor 5511

    Bjarne is right but from my experiance air can be sucked in even if no diesel is leaking out. The glas bowle is critical and very hard to get tight. Do you se an airbubble in the bowle is it an indication that air is sucked in. From the symtome description I bet it is an air problem. Even the...
  12. Zetor 3340 engine oil filter

    question Zetor 3340 engine oil filter

    You can buy a kit to convert to a spin-on filter. In the kit there ia a new pressure valve. You have to replace the pressure valve sitting close to the oil pump in the engine oil sump. I bought my kit from atpmotor.cz
  13. No forward or reverse (Zetor 5011)

    No forward or reverse (Zetor 5011)

    My experience is that the key switch is the weak link. Check if the instrument bulbs is lit normally. If you have a multimeter check if you have 12 V on the start button and if you press the button has 12 V on both poles. If yes, the fault lies in the lead from the startbutton to the starter...
  14. 5211 Battery Size?

    5211 Battery Size?

    Type 622 has a specific location for the poles. Not sure that Zetor sold in the US has the same type and location of the terminals. Measure the battery compartment and buy a battery suitable for 130 - 150 Ah and at least 900 CCA. Why not try an Optima. they are manufactured in US / Mexico and...
  15. 5211 Battery Size?

    5211 Battery Size?

    Battery type 622 can be delivered from 125 to 180 Ah and cca up to 1000. High CCA helps start in cold weather. Have a look at Exide Maxxima or Optima both with AGM technology.
  16. 5211 Battery Size?

    5211 Battery Size?

    In the manual it is recomended150Ah. If the winters is not so cold you can use a bit smaller. I use a Optima 50Ah with a cca 810A and it works fine in the Nordic winter. If you have a multimeter messure the outgoing voltage from the alternator. If it is 14.1-14,4 the carging works. Messure the...
  17. Zetor 5340 access to cab fans

    Zetor 5340 access to cab fans

    Lift the outside roof by loosing the two bolts in the front of the roof sides and tilt it up. Then you get access to the two fans and heater element as well as the slow speed resistors. Hazze

    Try the Finnish company that works mainly with the old models. https://www.motocheck.fi/
  19. 7245 charging problems

    7245 charging problems

    Two possible errors. If the generator slowly pulls out the battery when not in use the fault lies in one of the diodes in the generator. Also check the generator charcoal so they are not worn out or stuck. A new generator is relatively cheap today so replacing the diode bridge may not pay off.
  20. Zetor 6211 - Coolant Temperature Gauge

    Zetor 6211 - Coolant Temperature Gauge

    Even if the thermostat is stucked in open position the gauge will move a bit after running the tractor for a while and the engine feels warm. This of cause if the meter and sensor works.
  21. Zetor 6211 - Coolant Temperature Gauge

    Zetor 6211 - Coolant Temperature Gauge

    Do not know how it is on your model but on 4340 the sensor is located on the thermostat housing and there goes one cable to the sensor and a ground cable to the house itself. Check this ground cable so you have ground to the sensor otherwise no current can flow.
  22. Zetor 6211 - Coolant Temperature Gauge

    Zetor 6211 - Coolant Temperature Gauge

    My temperature sensor 904 ohms at 5 degrees C. Connected to 12V it flows about 15 mA which increases at higher temperature. If you measure the current between the sensor and the meter, a smaller current will flow as the meter has an internal resistance. If there is no current flow, either the...
  23. Zetor 6211 - Coolant Temperature Gauge

    Zetor 6211 - Coolant Temperature Gauge

    The sensor is a NTC type that will say high temp low resistant. I'll measure the value of mine 4340 tomorrow. Try to find out if any currant flows through the sensor by connecting the voltmeter between the sensor and the gauge. Also check so you dont have any bad connection from the gauge and...
  24. Zetor 6211 - Coolant Temperature Gauge

    Zetor 6211 - Coolant Temperature Gauge

    Take a multimeter and messure the sensor resistans.. The sensor is just a variable resistor and the gauge measure the currant. If the gauge works when conected to earth my belive is a sensor interruption. I do not know the value of the resistance but it is a matter of kohm not mohm.
  25. At My Wits End with 3320 UR1

    At My Wits End with 3320 UR1

    One carbon brush not in contact with the collector gives exactly the same symtom as a bad battery. The starter turns very slowly
  26. 4320 won't start

    4320 won't start

    Do you see a airbuble in the glass bowle. Classical problem was bad and cracked hoses, The pump sucks air. I had the same problem on my 4340, changed all hoses and installed a electrical liftpump. Do not forget the hoses from the injection nozzles back to the injection pump. Buy rubber hoses...
  27. 3320 not charging

    3320 not charging

    If the lamp and wire to the regulator is ok you will most likely find the problem in the alternator. The regulator or the rotor windings. How about the carbon bruches? The lamp gives a small current which magnifies the rotor and the generator starts and gives a voltage whereby the lamp now gets...

  29. glow plug controller replacement on Zetor 6441?

    question glow plug controller replacement on Zetor 6441?

    I became uncertain if 6441 is equiped with the type of coldstart i described above if not just forget what i said.
  30. glow plug controller replacement on Zetor 6441?

    question glow plug controller replacement on Zetor 6441?

    Is the glowplug OK? Is the electrical fuel valve OK. The relay will give a 4 sec long on-signal to the valve when activating the starter to let diesel in to the glowplug.
