Final Check; Possible Adjustments On Injection Pump Fitted To Engine; Anti-Stall Speed Adjustment - Fiat Bravo Service Manual

Bravo-Brava
- Secure dial gauge (A) on plunger ( C ) . Ensure that gauge is fitted with a preload of 10 - 1 5 mm, then
zero.
- Turn pump in its slots to move top of pump away from the cylinder assembly (maximum delay posi-
tion).
- Turn the crankshaft in its direction of rotation until piston no. 1 is turned exactly to T D C .
Never turn crankshaft against its direction of rotation. Otherwise tool or pump may be damaged.
Read distance off dial gauge. Then turn pump slowly in its slots until dial gauge shows exact fitting
distance indicated on pump label (e.g. 8.52 mm).
Now tighten pump retaining screws fully.

Final check

- Turn crankshaft in its direction of rotation by a few revolutions (at least 2) until piston no. 1 is exactly
at T D C . The dial gauge reading should correspond to the reading printed on the pump label. Other-
wise, repeat procedure described above with greater accuracy.

POSSIBLE ADJUSTMENTS ON INJECTION PUMP FITTED TO ENGINE

Before adjusting pump, engine must be at service temperature, i.e. radiator cooling fan must
have come on at least twice.
