4.  GEAR CHANGING

 

The main function of the gears is to achieve more speed and power. The strongest gear is first gear, then second, third and so on. Take-off is usually in first gear, then continue to increase speed until second gear speed, then third etc. until the vehicle reaches normal cruising speed. 

In a five-speed gearbox a guideline to change gears is as follows:

 

Start to 20 km/h  First gear 
Up to speed 40 km/h 

Second gear

Up to speed 55 km/h  Third gear
Up to speed to 70 km/h  Fourth gear
Above 70 km/h   Fifth gear
First and second gears is best engaged by cradling the gear lever in a back-hand fashion as shown! This way the hand works naturally against the return spring. The gear lever returns to neutral position by itself.

 

The seven steps for gear-changing up:

1 Reach the correct speed. If you cannot hear the sound of the engine, read the speedometer (or rev-counter) to change at the correct time.
2 Position your left hand on the gearlever. For engaging first and second gears, place your hand in a back-hand fashion, as shown. Don’t use fingers or grab the knob tightly. A smoother change is achieved by feeling the gearlever and guiding it with the palm of your hand.
3 Push down the clutch. The faster the better and all the way down.
4 Right foot off accelerator. Fast, a split second after ‘clutch down’.
5 Shift the gear lever with a little pause in neutral, to achieve a smoother change.
6 Press accelerator and bring up clutch. Apply sufficient power (the lower the gear the more power) and a pause half-way up, as the clutch engages (most importantly in lower gears, as these are very strong).
7 Keep accelerating. Repeat procedure in each gear until cruising speed has been reached.

The process for gear changing down is basically the same as for changing up, except that the correct speed is reached by braking, not accelerating. There's only one difference: There is no need to change gears before turning a corner or stopping. When the lower speed has been reached, select the matching gear! Downhill or in slippery conditions a lower gear may be selected to assist the brakes! (See also Section 24).

 

When driving uphill add extra speed before changing gear. An automobile loses speed during the gear change process, as soon as the clutch is depressed.

Downhill it is the opposite - gear change can be done at a lower speed. Gravity increases speed naturally. (Take-off may even be OK in second gear, depending on the gradient). 

When driving downhill,  you may still need to brake, during the gears changing process! The brake and clutch have no direct link.

 

Problems with gear changing may involve one or more of these:

 

1. Trying to change at the incorrect speed. This happens often when driving uphill. Because speed is being lost, learner drivers rush and select the wrong gear.
2. Selecting the wrong gear. Fourth gear is very often engaged instead of second, when not handled in the back hand fashion, as shown above. 
3. Dropping the clutch on engagement. Many learners don’t hold the clutch at the halfway point on engagement. This results in a jolt, especially in first and second gears. The root cause of this problem may stem from not keeping the ankle firm and/or not bending the knee when bringing up the clutch.
4. Keeping the accelerator depressed, after the clutch has been pushed down. The engine will rev unnecessarily. 
5. Lifting the foot off the accelerator and then pressing down the clutch. The engine is suddenly starved of petrol. 

Lifting off the accelerator when the vehicle is in motion (decelerating) must be done very slowly (especially in the stronger gears 1st and 2nd.) The engine responds without a jolt. Decelerating is an important part of slowing a vehicle and/or coming to a smooth stop. (For gear changing in automatic vehicle see Section 24.) 

Smooth gear changing adds pleasure to the joy of motoring.
