Self-locking bolts and screws
Self-locking bolts and screws, i.e. nylon patched or
trilobular thread can be re-used providing resistance
can be felt when the locking portion enters the
female thread.
Nylon patched bolts and screws have a locking agent
pre-applied to the threads. They are identified by the
presence of a coloured section of thread which
extends for up to 180° around the thread.
Trilobular bolts (i.e. Powerlok) have a special thread
form which creates a slight interference in the
tapped hole or threads of the nut into which it is
screwed.
DO NOT re-use self-locking fasteners in critical
locations (e.g. engine bearings, flywheel). Always
use the correct replacement self-locking nut, bolt or
screw.
DO NOT fit non self-locking fasteners in applications
where a self-locking nut, bolt or screw is specified.
Nut identification
Nut identification
A nut with an ISO metric thread is marked on one
face or on one of the flats of the hexagon with the
strength grade symbol 8, 12, or 14. Some nuts with a
strength grade 4, 5 or 6 are also marked and some
have the metric symbol M on the flat opposite the
strength grade marking.
A clock face system is sometimes used as an
alternative method of indicating the strength grade.
The external chamfers or a face of the nut is marked
in a position relative to the appropriate hour mark on
a clock face to indicate the strength grade.
A dot is used to locate the 12 o'clock position and a
dash to indicate the strength grade. If the grade is
above 12, two dots identify the 12 o'clock position.
When tightening a slotted or castellated nut, never
loosen it to insert a split pin except where
recommended as part of an adjustment. If difficulty is
experienced, alternative washers or nuts should be
selected, or the washer thickness reduced.
Where bearing pre-load is involved, nuts should be
tightened in accordance with special instructions.

Refit
NOTE: Following front or rear timing belt
refitment, it is possible that, after rotating the
engine and positioning the crankshaft pulley to
the 'SAFE' position, the timing marks on the
rear timing gears may be misaligned. This
misalignment is acceptable provided that the
timing belt refitting procedure was carried out
correctly.
1.Clean camshaft gears and hubs, crankshaft
gear, tensioner and water pump pulleys.
CAUTION: If the sintered gears have been
subjected to prolonged oil contamination,
they must be soaked in a solvent bath and
then thoroughly washed in clean solvent
before refitting. Because of the porous
construction of sintered material, oil
impregnated in the gears will emerge and
contaminate the belt.
2.Fit hubs to camshaft gears and fit gears to
camshafts. Fit new bolts and tighten sufficiently
to allow gears to rotate without tipping.
3.Position timing belt to crankshaft gear.
NOTE: To prevent the timing belt from
disengaging from the crankshaft gear when
fitting, fit a suitable wedge between the belt and
oil pump belt guard.
4.Fit tool LRT-12-197 into each exhaust
camshaft in turn.5.Using assistance, rotate each exhaust
camshaft slightly and align timing marks on LH
and RH rear camshaft gears.
6.Remove tool LRT-12-197 from exhaust
camshaft.
7.Fit tools LRT-12-175 to LH and RH rear
camshaft gears.
8.Rotate both front inlet camshaft gears fully
clockwise as viewed from front of engine.
9.Using fingers only, fit timing belt to gears,
starting at the crankshaft gear and working in
an anti-clockwise direction, keeping the belt run
as taut as possible and turning the camshaft
gears only a minimum amount anti-clockwise to
fit timing belt.
CAUTION: Gears must not be rotated anti-
clockwise more than one tooth.
10.Position an Allen key in tensioner backplate
and hold tensioner pulley against timing belt.
