Torque Practicals in the Automobile Lab
A standard motor mechanic exercise is refitting a cylinder head or cover in the correct order. On a dissectible engine such as the 4 Stroke 1 Cylinder Diesel Engine, trainees run the nuts down. They then tighten them in the given sequence in two or three stages. The teacher stores each stage value as a pre-set before the class starts.
In the fitting shop the same wrench checks a bolted flange. One bolt head is held with a ring from the Box End Spanner Set while the nut is brought to torque. Students then repeat the reading in N m and kg cm to practise unit conversion.
Frequently Asked Questions
What torque range does it cover?
It measures from 4.2 to 85 N m. The unit can be switched to ft lb, in lb or kg cm, so a figure from a service manual is used as written.
Does it read when loosening as well as tightening?
Yes. It reads in both clockwise and counterclockwise directions, so it can tighten left-hand threads or check the torque needed to start a nut moving. Free a seized nut with a breaker bar, not with the torque wrench.
What are the pre-sets for?
Each of the nine pre-sets stores a target torque. In a job done in stages, such as a head tightened in three passes, each stage value is called up in turn instead of being keyed in again.
How is a digital torque wrench different from an analog one?
A digital wrench measures with an electronic sensor and needs batteries. The Analog Torque Wrench is set mechanically in N m or ft lb, from 10 to 80 N m, and runs without power.
When should I stop pulling?
Pull slowly and steadily, and stop as soon as the LED shows that the pre-set torque is reached. A jerk at the end carries the reading past the target, and the extra torque stays in the joint. If you overshoot, slacken the nut and tighten it again.
