External preload adjustment process:
It is important to know that the lock nut must be pushed while turning (the tool must push the lock nut
completely straight in order to be able to move the nut all the necessary travel). Note that it is made by clicks
(20 clicks per revolution). Then, it is therefore to stop on a click to be sure of the good lock nut desired
position.
 It is not necessary to remove the left driveshaft.
 Lock the right driveshaft or wheel.
 Use the hex-head spanner of 8 mm in order to tighten/untighten the nut rounded on the previous
picture. Then you can adjust the preload:
o By turning clockwise in order to decrease the preload.
o By turning anti-clockwise in order to increase the preload.
Note:
 There is a second way to adjust the preload:
o Push the lock nut with the 8 mm hex-head spanner and hold it by hand.
o Turn the right wheel forward to increase the preload or backwards to decrease.
Preload checking process:
 Lock the left wheel using the driveshaft bolt spanner with a dynamometer.
 Turn the right wheel and check on the dynamometer the preload value.
Notes:
 Recommended preload range between 50 and 150 Nm. The cold measured preload is
approximately 15% higher than warm measure.
 Preload decreases from approximately 15% after first 50 kilometres of running.
 Different ramps are available on Audi RS 3 LMS SEQ Spare Parts Catalogue. Only the ramps
homologated on the Audi Sport RS 3 LMS SEQ Technical Form can be used: 60/30, 45/30 and
35/30.
 Different preload springs with a different working range are available on Audi RS 3 LMS SEQ Spare
Parts Catalogue.
 For detailed information see the SADEV ST82-17 Technical Manual on the Audi Sport website.
Fuel tank
The 100l FIA FT3 fuel tank is working with one unique fuel pump and a Venturi hoses system. The pump is
controlled through a PWM fuel control module.
Refuelling tool:
The fuel tank is served with a FIA approved fast coupling plug. The socket is the necessary connecting-tool
for refuelling the tank. This part is available on the Spare Parts Catalogue.
