each new flywheel retaining bolt (unless they
are precoated) and install the new bolts.
8 Lock the flywheel by the method used on
removal then, working in a diagonal sequence,
evenly and progressively tighten the retaining
bolts to the specified torque.

Inspection
1 If improved access is required, firmly apply
the handbrake, then jack up the front of the
car and support it securely on axle stands
(see Jacking and vehicle support).
2 Check the mounting rubber to see if it is
cracked, hardened or separated from the
metal at any point; renew the mounting if any
such damage or deterioration is evident.
3 Check that all the mounting's fasteners are
securely tightened; use a torque wrench to
check if possible.
