UAZPARTS Workshop Reference
UAZ Bukhanka Torque Specifications
A practical tightening-torque reference for commonly serviced cooling, sensor, drivetrain, axle, suspension, steering and brake components.
Use the right torque, not just a tight bolt
Too little torque can let a flange, wheel or suspension connection work loose. Too much can strip a thread, crush a sensor or overload a fastener. The factory values were originally published in kgf·m; we have added workshop-friendly N·m conversions throughout.

0.45–1.0 kgf·m
M8
13.7–17.7 N·m
1.4–1.8 kgf·m
M10
29.4–34.3 N·m
3.0–3.5 kgf·m
Important workshop notes
Torque alone does not guarantee the correct clamping force. Before assembly:
- Make sure the thread, bolt, nut and mating surface are clean and undamaged.
- Do not lubricate a thread unless the relevant factory procedure calls for it; lubrication changes the achieved clamping force.
- Replace damaged, stretched or specified single-use fasteners and locking elements.
- Use the prescribed tightening sequence and stages where applicable.
- For brakes, steering, wheels and suspension, have the work checked by a qualified mechanic if you are unsure.
