Dismantling and Assembly Practicals

Motor mechanic and fitter trainees use a combination set when they strip and rebuild a unit such as a pump or a gearbox cover. They break each tight nut loose with the ring end, then spin it off with the open end. The unit is held in a Bench Vice, and the parts are laid out on the bench in the order they came off.

On reassembly, students run each nut down with the open end and give it the final pull with the ring end. Where the job gives a tightening figure, the last turn is made with a socket on a Torque Wrench. A Socket With Ratchet Handle Set is brought in for nuts sitting deep in a recess.

Frequently Asked Questions

Why does a combination spanner have two different ends?
The open end slides onto a nut from the side and is quick to use where a ring cannot be dropped over the top. The ring end grips the nut all round, so it is used to break a tight nut loose and for final tightening.

What is chrome vanadium steel?
It is a steel alloyed with chromium and vanadium. Spanners and sockets are often made from it because it hardens well and takes repeated loading without cracking.

How do I pick the right spanner from the set?
Try the ring end first. The right size drops over the nut with almost no play. One size too large rocks on the flats and will round the corners if you pull on it.

What if a nut does not fit any spanner in the set?
Do not force a near size onto it, because a spanner that rocks on the flats rounds the corners. Check whether the nut is an inch size, then use a spanner from the matching system. Keep metric and inch spanners in separate sets so they are not mixed up.

How should the set be stored?
Wipe the spanners free of oil and grit after use and put each one back in its place in the blister pack. Keeping them in order shows at a glance when a size is missing at the end of a class.
