MAINTENANCE
MAINTENANCE 10-7
Tyres
Check
1.Check for any apparent damage to tyres,
paying particular attention to side walls.
2.Look at tyre treads and check for any unusual
wear patterns which may indicate out of
specification adjustment of steering or
suspension.
NOTE: Any adjustments to steering or
suspension will be subject to additional labour
and/or material cost and should not be carried
out without the authorisation of the customer.
3.Measure the tread depth across the width of the
tyre and around the circumference. Annotate
the maintenance check sheet with the lowest
figure obtained from each tyre.
NOTE: Any requirement to replace tyres should
be advised to the customer before any remedial
work is carried out. This will be subject to
additional labour and/or material cost and
should not be carried out without the
authorisation of the customer.
CAUTION: If new tyres are to be fitted,
ensure that they are fitted to the rear axle
only or to both front and rear axles. DO NOT
fit new tyres to front axle only.
Brake Pads and Calipers
Brake Pads
1.With front road wheels removed, check brake
pad thickness and ensure that both pads are
wearing evenly.
2.Check brake discs for signs of cracking,
excessive scoring or oil contamination.
NOTE: Any requirement to replace brake pads
or brake discs should be advised to the
customer as this will be subject to additional
labour and/or material cost and should not be
carried out without the authorisation of the
customer.
3.Check for any signs of brake fluid leakage from
caliper seals, hoses or unions.
4.Using brake cleaner, remove excessive
deposits of brake dust from pads, calipers and
disc shields.

31.Check that fitted height of valve guide, 'A', is
6.00 mm (0.24 in).
32.Check condition of valve seats and existing
valves that are to be re-used.
33.Renew valve seat inserts as necessary.
CAUTION: Do not damage counterbore
when removing insert.
34.Cool replacement valve seat inserts using
liquid nitrogen and press into cylinder head in
one continuous operation.
CAUTION: Do not heat cylinder head.
Inserts must not stand proud of combustion
face on completion of cutting operation.
35.Cut valve seats using a suitable pilot and the
following cutters:
l15° - To cut first angle
l45° - Make final cut and remove any burrs
l60° - To narrow seat and obtain correct
valve seat width
36.Check valve seat width and face angle:
lSeat width - 'A' - Inlet = 1.2 mm (0.05 in);
Exhaust = 1.6 mm (0.06 in)
lValve face angle - 'B' - Inlet and exhaust =
45°
37.Lap each valve to its seat using grinding paste.38.Apply Prussian Blue to valve seat, insert valve
and press it into position several times without
rotating. Remove and check valve for even and
central seating: seating position shown by
Prussian Blue should be in the centre of valve
face: a: High towards stem, increase 60° cut
and restore seat width. b: Low towards edge,
increase 45° cut and restore seat width. Lap
and recheck valve seating.
39.Check valve stem fitted height - 'A'.

Petrol.
CAUTION: If valve stem fitted height is
above service limit, fit new valve and re-
check. If still over limit, renew valve seat
insert.
40.Clean valve springs and lubricate valves.
Reassembly
1.Lubricate new valve stem oil seals with clean
engine oil.
2.Using tool LRT-12-071 fit new valve stem oil
seals.
3.Fit valves.
