Tightening torque Kubota Z402 | Z482 | Z602 | D622 | D722 | D782

Kubota tightening torques of head bolts and other items

General information on the tightening torques of all Kubota engines as an example the head bolts etc.

An important rule is that the head bolts must first be oiled, on which the correct NM can then be measured with the torque wrench. So this means first cleaning the head bolts with the wire brush, if necessary, and then dipping them in oil. Drain this so that it cannot affect the tightening torque.

Supplies: tightening torque wrench
