8.5.3. Mechanism of management of a butterfly valve

GENERAL INFORMATION

Mechanism of management of a butterfly valve

1. The torsion spring
establish on a clamping plate and tighten,
having established a cover
2. Nut
3. Cover
4. Washer
5. Clamping plate
6. Plug
7. Pin
for a butterfly valve
8. Washer
9. System of ignition
10. Arm

11. Arm
for adjustment of installation of a rope of an accelerator on an accelerator pedal
12. Arm
13. Switching lever
14. Cover
15. Accelerator rope
16. Limiter
for an accelerator pedal
17. Accelerator pedal
18. Clip

Adjustment

PERFORMANCE ORDER

1) remove a casing from the mechanism
	2) weaken an inhaling of nuts 1 and 2 and remove a clip 3
3) turn arms of a rope of a butterfly valve against the stop (situation at which the butterfly valve is completely open) and hold them in such situation
4) the tool 3004 (two screw coupling couplings) can be used for deduction of arms of a rope of a butterfly valve in situation at which the butterfly valve is completely open. If you have no tool 3004, use two screw coupling couplings of the suitable size. Hook on one end of the coupling for the lever of the lower arm of a rope and other end – for bottom edge of a rack of a cowl
	5) install the plug, 17 mm long between a pedal of an accelerator and the limiter of a pedal
6) squeeze out an accelerator pedal up to the end that it rested against the plug, and hold it in such situation (you will need the assistant)
	7) pull an accelerator pedal rope in the direction of an arrow and establish a clip 3
8) pull a rope to the transmission in the direction of an arrow you will not feel resistance of a spring of inclusion of a low gear yet
9) turn a nut 1 towards an arm and tighten a nut 2
10) remove the tool 3004 (screw coupling couplings)

Adjustment, check

When the pedal of an accelerator is not pressed, the lever of a butterfly valve has to rest against the limiter for idling.

PERFORMANCE ORDER

1) squeeze out an accelerator pedal to situation at which the butterfly valve is completely open

2) the end of a pedal has to is in 15–20 mm from the pedal limiter

3) squeeze out an accelerator pedal to the limiter

4) the lever of switching of the transmission has to concern the gear shifting limiter

5) the spring between arms of a rope has to be compressed
