Common Vehicle Faults And Remedies


Stirring Stiffness
Speaking of possibility, an automobile steering might become rigid and painful to stir; what might be the probable causes?
An automobile steering is that which the driver uses in controlling the direction or guide the course of his or her automobile or car while in motion. Flexibility in the steering always aids the ease of an automobile navigation.

From experience, below are listed possible causes of a stiff steering:
(1)    The automobile may have a low or uneven tyre pressure
(2)    The automobile steering gear or connections adjusted may be done too tight
(3)    The front springs may be sagged
(4)    The front axle or suspension arms of the automobile may be bent or twisted
(5)    Another probable cause may be as a result of an excessive caster
(6)    The steering of an automobile may become stiff due to insufficient or incorrect lubricant used
(7)    Another probable cause may be due to frame bent or broken
(8)    The steering of an automobile may be stiff reacting to stub-axle knuckle bent

The solutions to the aforementioned possible causes of a stiff steering are to check one by one and readjust or correct the cause. Check wheel alignment by testing the camber, king-pin inclination and caster. Correct front axle as necessary. Replace independent front-wheel arms with new ones.

Front Wheel Alignment Check
In order to be able to check the front-end alignment, all checks must be made with the automobile level and with the weight of the automobile on the wheels. No load on the vehicle is usual, but in some cases a load is specified.
Before any attempt is made to check or adjust caster, camber, toe-in, king-pin inclination, or toe-out, an inspection routine should be made on parts which influence the steering of the automobile.

The inspection routine which must be carried out prior checking front-end alignment is as follows:
(1)    Inflate tyres to the recommended pressures
(2)    Check the adjustment of the front-wheel bearings, and correct if necessary
(3)    Also check steering-gear adjustment
(4)    Check the runout of wheels and tyres, and correct to 1/8in. if necessary
(5)    Also check the shock-absorber action, and correct if necessary
(6)    Check for looseness at the king-pin; if found excessive, it must be corrected as well before alignment readings will have any value
(7)    Check for looseness of track-rod ends, and replace if necessary
(8)    It is also necessary to check the front leaf springs (if fitted) and tighten U-bolts

(9)    Check the wheels and tyres for balance, and correct to specification if necessary.

Release-Lever Adjustment Necesities
Let’s try look at the method of release-lever adjustment when assembling a Borg and Beck clutch.
The release lever must be set by means of the special Borg and Beck according to the diagram below:
Assemble the gauge plate in the flywheel, in the position normally occupied by the driven plate, and mount the cover assembly on the flywheel, tightening the holding screw a turn at a time by diagonal selection and ensuring that the gauge plate is correctly centered with the three machined lugs directly under the release levers. Any position of the gauge-plate lugs will give satisfactory results on the 11-in. models which have four release levers.
After the cover assembly has been fitted to the flywheel, place a short straight-edge across the centre boss and the bearing surface of one release lever, then turn the adjusting nut until the lever is exactly the same height as the gauge-plate boss. Repeat the same process for the other levers.

[NOTE:-]
  1. Flywheel is a rotating mass used to maintain the speed of a machine within certain limits while the machine receives or releases energy at a varying rate.
  2. Clutch is one of the pedals used between engine and gearbox in an automobile to disengage or interrupt power transmission.
  3. Gearbox is part of an automobile’s transmission containing the train of gears, and to which the gear lever is connected.
  4. Gear is a configuration of the transmission of an automobile or motor car so as to achieve a particular ratio of engine to axle torque.
