4. OPERATION

4.1 Remove gearbox from the vehicle as per the manufacturer's instructions.

Note: The dual mass ywheel is in two parts of which, one half is connected to the gearbox and thus will be removed

when the gearbox is removed from the vehicle, and the other is connected to the crankshaft. Testing is carried out on the

engine side.

4.2 TEST1:TESTINGTHEROTATIONALARCSPRINGS/DAMPERSPRINGSFREEPLAY(Refertogs.2&3)

4.2.1 Attach the slotted bar (1) across the ywheel using the adaptors (2) supplied so that the angular torque gauge (3) is in

the centre of the ywheel, see g.2. If the ywheel has an odd amount of xing screws, see g.3, it is not possible to

mount centrally and a reading will have to be taken by counting the ring gear teeth movement then working out the

degrees of free play (see below).

4.2.2 Lock the ywheel using the Ring Gear Locking Tools (7) to stop the ywheel rotating under test. Spacers/washers may

be required to align the locking tool with the ring gear.

4.2.3 Lightly (using the palm of your hand) turn the Slotted Bar (1) in either direction by the handle to nd (start to compress)

the Arc spring inside the ywheel. Then remove the pressure and allow the ywheel to return to the rest position. Zero

the angular torque gauge (3) and lightly rotate in the opposite direction to nd the opposite spring, then allow the ywheel

to return to the rest position, then take a reading from the degree plate. When rotating, a thud may be heard which is

common and not a faulty ywheel.

Note: The Arc springs are packed in grease, so a small amount of grease from the vent holes is normal but excessive

grease will mean that the ywheel needs replacing.

4.3 TEST2:TESTINGTHECENTREBEARING/BUSHFORWEAR-ROCK(REFERtog.4)

4.3.1 Fit DTI gauge (4) using the bracket provided (5) to the engine and locate the DTI tip onto one of the adaptors (2) that is

holding the Slotted bar (1) onto the ywheel. Pre-load the DTI gauge, pull the slotted bar handle gently towards you and

set the DTI gauge to zero. Then gently (using nger and thumb) rock the slotted bar handle back and forth to check the

wear in the bush, taking the reading from the DTI. When checking for wear we are checking for rock NOT end oat which

on some ywheels is normal.

4.3.2 Once the two measurements have been taken, it is important to check the tolerance to the specic vehicle being worked

on using the manufacturer's specications. If the measurement exceeds the manufacturer's specications the Dual Mass

Flywheel will need to be replaced.

Examples of readings are: Maximum Freeplay 15° and Maximum Rock 1.6mm, but tolerances will vary depending on the

vehicle being worked on.

 Calculationfordegreesrotationbycountingtheywheelteeth(example)

If a ywheel has 112 teeth and freeplay is 4 teeth.

360degrees/112teeth = 3.214 X 4 = 12.85 degrees
