Princip uzávěrky u I.generace?
Ať hledám, jak hledám, nikde jsem nenašel samotný princip uzávěrky mezinápravovýho difu u ravky I.generace. Má problém s únikem oleje při zaplé uzávěrce, tak chci zjistit co a jak. Vím, že se tam podtlakem cosi sepne, ale nevím, zda se jedná o klasickou "špéru", či o nějakou visko spojku, protože na první pohled mi přijde že od každé nápravy vede do převodovky olejová hadice.

TROUBLE SHOOTING
CENTER DIFFERENTIAL LOCK SYSTEM
1. Raise vehicle off ground so all 4 wheels can rotate. Apply parking brake and start engine. Turn center
differential lock system on.
2. Depress clutch pedal and shift into 2nd gear. With engine idling, gradually engage the clutch and ensure
engine stalls.
3. With parking brake and engine on, turn center differential lock system off. Depress clutch pedal and shift
into 2nd gear. With engine idling, gradually engage the clutch and ensure front wheels rotate.
CENTER DIFFERENTIAL LOCK INDICATOR LIGHT
Turn ignition on. Ensure indicator light is off with center differential lock system off, and on with system on.
WARNING BUZZER
1. Start engine and ensure warning buzzer does not sound when center differential lock switch is turned on.
NOTE: If the buzzer continues to sound, point the wheels straight ahead, accelerate or
decelerate, or drive the vehicle in reverse to stop the buzzer.

Change position of vacuum hoses at vacuum switching valves.
2. Turn off center differential lock switch and ensure warning buzzer sounds. Change position of vacuum
hoses at vacuum switching valves once again, and ensure buzzer stops. If buzzer operation is not as
specified, check vacuum hoses.
TESTING
CENTER DIFFERENTIAL LOCK ACTUATOR
Vacuum Tank Chamber
Disconnect vacuum hoses (except No. 1) and plug hose No. 3. See Fig. 3 . Apply 20" Hg of vacuum to hose No.
0 and ensure indicator needle remains steady. Actuator may leak 1.7" Hg or less during 15 seconds.
Lock Chamber
Disconnect vacuum hoses No. 1 and 2. Apply 20" Hg of vacuum to hose No. 1 and ensure indicator needle
remains steady. Actuator may leak 1.7" Hg or less during 15 seconds.
Free Chamber
Disconnect all vacuum hoses and plug hose No. 3. Using a "T" fitting, apply 20" Hg of vacuum to hoses No. 0
and 2. Ensure indicator needle remains steady. Actuator may leak 1.7" Hg or less during 15 sec

Díky za snahu, ale konkrétní princip tam není. Pouze diagnostika a systém el. a podtlakového zapnutí. Mě jde o to, že mi při zaplé uzávěrce neznámo odkud teče olej, tak jsem chtěl vědět, zda jde o nějakou špéru spínanou tlakem oleje nebo o nějakou hydrospojku.
Z obrázku jen matně vyplývá, že by mohlo jít právě o nějakou špéru, ale není to příliš konkrétní nákres.
