Why is my Dong Feng ZB45 Tractor exhaust smoking?
- R
  Raymond CharlesAug 19, 2025
  Exhaust smoking in your Dong Feng Tractor can stem from several causes. A slow or partially blocked injector nozzle can cause this problem; consider replacing or servicing it. Overloading the engine is another potential cause, so adjust the gearing accordingly. Incorrect fuel injection timing can also lead to exhaust smoke, so make sure to adjust it. Other causes include poor valve sealing or incorrect timing (check and adjust), uneven fuel delivery from the injector pump or injectors (check and service), a blocked air filter (clean or replace), or worn cylinder liners and piston rings (replace them).

What to do if my Dong Feng ZB45 Tractor has oil pressure problems?
- K
  Kevin JonesAug 21, 2025
  If your Dong Feng Tractor is experiencing oil pressure problems, start by checking the oil level and refilling it as needed. Also, check whether the oil intake is broken, as the oil pump might be sucking air. Other potential causes include a malfunctioning oil filter (replace it), a faulty oil filter pressure regulator valve spring (replace it), a worn-out oil pump (replace it or reduce its paper gasket), or excessive bearing clearance (check and replace bearings as necessary).

Why is my Dong Feng Tractor engine low on power?
- A
  Austin JohnsonAug 26, 2025
  A Dong Feng Tractor engine might be low on power for a few reasons. Check if the third ring is fitted upside down and refit it correctly, ensuring the mark '(up)' faces upward. Worn piston rings and valve guides can also reduce power; replace them. Finally, too much oil in the crankcase can hinder performance, so drain the oil to the correct level.

How to fix clutch slip in my Dong Feng ZB45 Tractor?
- J
  Julie RodriguezAug 28, 2025
  If your Dong Feng Tractor's clutch is slipping, several factors could be responsible. Begin by checking the friction disc for oil stains; if present, wash the disc with petrol and repair the oil leak. A weakened or broken pressure plate spring can also cause slippage; replace it with a new one. Limited or no clutch pedal free travel is another possibility; readjust the pedal free travel as specified. Furthermore, a warped, unevenly worn, or worn-out clutch plate could be the culprit; rectify or replace it. Lastly, misaligned release levers can cause clutch slip, so adjust and align the lever ends in the same plane.

Why does my Dong Feng ZB45 have insufficient lifting capacity?
- R
  Roy SullivanAug 31, 2025
  Insufficient lifting capacity in your Dong Feng Tractor could be due to several reasons. It may be caused by insufficient engine power output, so inspect and service/repair the engine. Also, check if the oil level in the transmission case is too low and replenish oil. Make sure that the weight in the bucket does not exceed the maximum specified loader capacity and reduce material load if needed. Other potential causes include lifting cylinder piston assembly leakage (check cylinders for leakage and repair as needed), a control valve leaking internally (replace the control valve and recheck operation), or a defective hydraulic pump (check and repair or replace).

What to do if the brake disengages incompletely on my Dong Feng Tractor?
- D
  Drew SmithSep 3, 2025
  If the brake on your Dong Feng Tractor disengages incompletely, it could be due to a few reasons. A weakened brake shoe return spring can cause this issue; replace it with a new spring. Also, check if the brake pedals are unable to return, this may be caused by a damaged pedal return spring or a seized operating shaft, and fix as required. Limited or no pedal free travel can also prevent full disengagement; readjust the pedal free travel.

Why is there an abnormal sound in the gearbox of my Dong Feng ZB45 Tractor?
- M
  Maria SanchezSep 9, 2025
  An abnormal sound in your Dong Feng Tractor's gearbox could indicate several issues. Excessively worn or damaged gearbox bearings or needle rollers might be the cause; check and replace them with new ones. Abnormal meshing of the main drive gears can also produce unusual sounds; examine the gear meshing zone print and backlash, and adjust them as per specifications. Lastly, worn-out spline shafts and sliding gears can cause noise; replace them with new parts.

How to start a Dong Feng ZB45 Tractor when the diesel engine fails to start?
- O
  orayNov 15, 2025
  If your Dong Feng Tractor's diesel engine won't start, several issues could be the cause. First, check if there's fuel in the tank and add fuel if needed. Air in the fuel system can also prevent starting, so bleed the air and identify the cause. A blocked fuel system is another possibility; replace the fuel filter and inspect the fuel delivery line. Other potential causes include worn-out injector pump components (replace them), blocked or poorly atomizing injectors (replace or service them), incorrect valve clearance (adjust to specifications), a valve leak (replace or grind the valve), a blown head gasket (replace and tighten the cylinder head), piston ring bypass (replace, clean, or reassemble the rings), incorrect injector pump or valve timing (readjust), low ambient temperature (use g...
