EXHAUST
CONCENTRATION
TEST
1.
Unscrew the plug fitted in the front end of the cotolytic converter ond fit odopter
and sample pipe (Part No. TOOQT0321A).
2.
Set the idle speed to 950
-
1000 r.p.m. with engine at normal running temperature.
3.
Dlsconnect the air injection by removing the air outlet hose (between air pump
and
diverter valve) from the air pump and blank off the hose with plug (Port No.
TOOOT0322A). Do not adjust idle speed with oir injection disconnected.
4.
With exhaust concentration anolyser attached to the sample pipe check the
reading.
Idle CO level at normal running temperature should be 3.5
-
4.5%.
S.
Adjust mixture as necessary. After every adjustment run the engine briefly at
2000 r.p.rn. then check the mixture at idle speed.
This
is
to ensure that the
piston in the
dash pots have settled correctly. For North American vehicles
(except California), with
o prefix
H
on the engine number and fitted with
a
"
Lumenition
"
distributor, the idle CO level should be less than
1%
with air on

PROCEDURE
FOR
TENSIONING
PUMP DRIVE BELT
1.
Slacken off the two pivot bolts under the pump just sufficient to allow movement
of the pump.
y'2.
Slacken off the two bolts on the tensioner.
3.
Move air pump to obtain the correct belt tension (see TECHNICAL DATA).
Tighten all fixing and tensioner bolts to a torque
lwding of 20lb.ff. (2.7k.grn)
and recheck belt tension.
