Valve timing - Angles
The angle values are determined by turning the driving shaft clockwi-
se
S = Piston at top dead centre
I = Piston at bottom dead centre
α = Intake valve open
β = Intake valve closed
γ = Exhaust valve open
δ = Exhaust valve closed
Timing angles for checking puposes
(valve clearance = 0,65÷0,70 mm)
α = 1° before S
β = 21° after I
γ = 23° before I
δ = 1° after S
HYDRAULIC PUMP
Hydraulic pump p.t.o
A hydraulic pump of group 1 (1P) or 2 (2P) can be installed on the gear
side, 3rd p.t.o.
Valve timing check
Check valve timing at the crankshaft.
The values shown are checked at the ywheel circumference (with
ywheel of 291 mm. diameter each degree corresponds to 2.5 mm).
Set valve clearance at 0.65÷0.70 mm (after checking restore the value
at 0.15÷0.20 mm).
Set dial gauge on intake valve to a zero value; by rotating the driving
shaft according to its direction of rotation you can measure α (intake
valve opening advance referred to top dead centre S) and ß (intake
valve closing delay referred to bottom (I) dead centre).
Follow the same procedure for exhaust valves checking γ (exhaust valve
opening advance) and δ (exhaust valve closing delay).
