ings diagonally with a tightening sequence.
♦ Especially delicate components, such as clutch pressure
plates, must not be distorted. Loosen and tighten bolts and
nuts in stages in a diagonal sequence.
♦ The tightening specifications given apply to unoiled bolts and
nuts.
♦ Always replace self-locking bolts and nuts.
♦ Make sure the contact surfaces and visible surfaces on the
nuts and bolts are waxed after assembling.
♦ Use a wire brush to clean the threads of the bolts that were
installed with locking fluid. Then insert the bolts with Locking
Fluid - AMV 185 101 A1- .
♦ Clean the threaded holes for the self-locking bolts or for the
bolts coated with locking fluid (for example with a thread tap).
Otherwise the bolts could shear the next time they are re‐
moved.
♦ Please make sure that the thread pitch is correct so that the
proper thread tap is used during cleaning, and the thread does
not get damaged.
♦ Make sure the contact surfaces and visible surfaces on the
nuts and bolts are waxed after assembling.
Bearings
♦ Install needle bearings with the lettered side (thicker metal)
facing the fitting tool.
♦ Insert all the bearings in transmission with transmission fluid.
♦ Replace all the tapered roller bearings that are on the same
shaft, and use tapered roller bearings from the same manu‐
facturer.
♦ Heat the tapered roller bearing inner races to approximately
100 °C (212 °F) with the Inductive Heat Unit - VAS6414- before
installing. Press on to the stop when installing, so there is no
axial clearance.
♦ Do not interchange outer and inner bearing races with those
from other bearing of the same size. The bearings are paired.
Shims
♦ Measure the shims at several locations with a micrometer cal‐
iper. Tolerance variations make it possible to find the exact
shim thickness required.
♦ Check for scratches and damages.
♦ Only install flawless shims.
