alibotean Postat Aprilie 9, 2008 Partajează Postat Aprilie 9, 2008 Am observat ca pe fata la roti/in mijlocul jentii aveam ceva ce parea un antifurt :) am vb azi cu fostul proprietar si mi-a spus ca de fapt de acolo se blocheaza diferentialul fata. Are 2 pozitii AUTO si LOCK. Imi poate explica si mie cineva cand ar trebui sa il blochez si daca pe auto se blocheaza si el? si ince situatii. Multumesc.

valissan Postat Aprilie 9, 2008 Partajează Postat Aprilie 9, 2008 Re: Diferential fata blocabil Your NISSAN is equipped with one of two 4WD systems, auto-lock free-running hubs or manual-lock free-running hubs. The auto-lock free-running hub is designed to allow for automatic 4-wheel drive engagement when the shift lever is moved to the 4H or 4L position. If your vehicle is equipped with this system, follow these operational cautions: CAUTION c The auto-locking hubs will make a clicking noise when engaging and disengaging. This is normal. c Accelerating quickly from a stop after shifting from 2-wheel drive to 4-wheel drive may not allow engagement of the auto-locking freerunning hubs and may cause a clattering noise. Continued use of the vehicle with this noise may damage the hub lock. In such a case, release the accelerator pedal to reduce the engine speed or stop the vehicle. c If the auto-locking hubs make a clattering noise after shifting from 4-wheel drive to 2-wheel drive, stop and move the vehicle about 7 to 10 feet (2 to 3 m) in reverse. c Under extremely cold conditions [below 5°F (-15°C)], the front axle shafts may rotate even with the transfer lever in the 2H position. If this occurs, the auto-locking hubs may make a clattering noise. To avoid this, drive first in 4-wheel drive to warm up the vehicle and differential gear oil. Then, shift to 2-wheel drive. SD0021 AUTO-LOCK FREE-RUNNING HUBS 4-16 c In cold weather, it may be necessary to reduce speed or stop the vehicle in order to shift from 2-wheel drive to 4-wheel drive. c When shifting into or out of 4-wheel drive while driving, do not stop shift lever movement midway. An incomplete shift may cause a clattering noise from the auto-locking hubs. Continued use of the vehicle with this noise may damage the hub lock. Drive in 4-wheel drive to stop the noise. Shift to 2-wheel drive as described. 4-17 TO SHIFT TRANSFER CASE: SHIFT PROCEDURE FOR AUTO-LOCK FREE-RUNNING HUBS From 2H to 4H Move the transfer lever to 4H at speeds below 25 MPH (40 km/h). It is not necessary to depress the clutch pedal. Perform this operation when driving straight. From 4H to 2H Move the transfer lever to 2H. This can be done at any speed, and it is not necessary to depress the clutch pedal. Perform this operation when driving straight. NOTE: For 2-wheel drive operation, set the free-running hubs in the disengaged position. AUTO-LOCK hubs will not disengage until the vehicle is moved about 3 feet (1 m) in the opposite direction of travel: c When driving forward, stop and move 3 feet (1 m) in reverse. c When backing up, stop and move 3 feet (1 m) forward, then move the vehicle about 3 feet (1 m) in reverse. This will allow for better fuel economy, quieter ride and less component wear. From 4H to 4L or 4L to 4H 1. Stop the vehicle. 2. Depress the clutch pedal. 3. Depress the transfer lever and move it to the desired 4L or 4H position. From 2H to 4L 1. Stop the vehicle. 2. Depress the clutch pedal. 3. Depress the transfer lever and move it to 4L. Change gears quickly and smoothly. From 4L to 2H 1. Stop the vehicle. 2. Depress the clutch pedal. 3. Depress the transfer lever and move it to 2H. NOTE: Follow the NOTE shown in shifting from 4H to 2H. 4-18 The manual-lock free-running hubs are designed to allow you to engage or disengage the front drive shaft to the front wheels. Before driving, set the free-running hub to the desired position: c 2-wheel operation — Turn the knob to the FREE position. c 4-wheel operation — Turn the knob to the LOCK position. Be certain to align the S mark on the knob with the c mark on the wheel hub. CAUTION c Never drive in 4-wheel drive (4H or 4L) with the free-running hubs in the FREE position. c Do not drive your vehicle with the left and right free-running hub set to different positions. c For the first 300 miles (483 km) it is recommended that you drive in the 2H position with the free-running hubs set in the LOCK position. c To ensure proper lubrication of front drive components, drive in the LOCK position for at least 10 miles (16 km) each month. SD0022 MANUAL-LOCK FREE-RUNNING HUBS 4-19 TO SHIFT TRANSFER CASE: SHIFT PROCEDURE FOR MANUAL-LOCK FREE-RUNNING HUBS From 2H to 4H 1. Stop the vehicle. 2. Set free-running hubs in the LOCK position. 3. Move the transfer lever to 4H. It is not necessary to depress the clutch pedal. From 4H to 2H Move the transfer lever to 2H. This can be done at any speed, and it is not necessary to depress the clutch pedal. Perform this operation when driving straight. NOTE: For 2-wheel drive operation, set the free-running hubs in the FREE position. This will allow for better fuel economy, quieter ride and less component wear. From 4H to 4L or 4L to 4H 1. Stop the vehicle. 2. Depress the clutch pedal. 3. Depress the transfer lever and move it to the desired 4L or 4H position. From 2H to 4L 1. Stop the vehicle. 2. Set free-running hubs in the LOCK position. 3. Depress the clutch pedal. 4. Depress the transfer lever and move it to 4L. Change gears quickly and smoothly. From 4L to 2H 1. Stop the vehicle. 2. Depress the clutch pedal. 3. Depress the transfer lever and move it to 2H. Tico BMW 525d Mercedes 412 Terrano2 2.7 TD Link spre comentariu Distribuie pe alte site-uri Alte opțiuni partajare...
valissan Postat Aprilie 9, 2008 Partajează Postat Aprilie 9, 2008 Re: Diferential fata blocabil Asa functioneaza lucrul ala, cu mentiunea ca in pozitia AUTO e automat, iar in pozitia LOCK reactioneaza ca un mecanism manual. NU are nici o legatura cu blocarea diferentialului, cupleaza planetarele din fata cu butucul rotii. Sfat: 1. Int otdeauna cuplarea se va face din pozitia oprit.Dupa ce ai terminat treaba cu 4x4 si ai adus maneta in pozitia 4x2, obligatoriu rulezi 3-4 metri inapoi, pentru a decupla planetarele. Toate astea pt pozitia AUTO, pt pozitia LOCK planetarele nu se vor decupla indiferent de pozitia manetei de cuplare. 2. 4x4 automat se va cupla inainte de intrarea in noroi sau altceva in care poti ramane impotmolit. In cazul in care te-ai trezit blocat inainte de a apuca sa cuplezi fata, obligatoriu se vor cupla MRL-urile manual(pozitia LOCK) inainte de a cupla restul transmisiei din maneta. Daca nu vei proceda asa risti sa barbieresti danturile din interiorul MRL-ului. 3. Atunci cand iesi in teren greu : paduri , noroaie ,zapada etc. cupleaza MRL-urile in pozitia LOCK cu ajutorul cheiei originale de roti, sau daca nu o ai foloseste o cheie de bujii din aceea de tabla care exista pe la Dacii.

alibotean Postat Aprilie 10, 2008 Autor Partajează Postat Aprilie 10, 2008 Re: Diferential fata blocabil Mersi pentru sfaturi, nu stiam ca trebuie sa merg 3m in directie opusa la cuplarea 4x4 sau 4x2 de la maneta de transfer. Am mers weekendul trecut si am cuplat si decuplat fara sa faca asta :) sper ca nu s-a bulit nimic. Am o nelamurire la toata povestea asta cu AUTO si LOCK. Care este diferenta intre a cupla din maneta de transfer pe 4H sau direct de la roata?

valissan Postat Aprilie 10, 2008 Partajează Postat Aprilie 10, 2008 Re: Diferential fata blocabil De la roata nu cuplezi toata transmisia, doar planetarele. Daca ai ramas impotmolit, atunnci cand cuplezi din maneta, se vor invarti planetarele in timp ce rotile din fata raman pe loc. O roata dintata, care se invarte nu se va cupla cu una care sta pe loc sau care are turatie diferita. Am scris sa mergi inapoi, dupa ce ai decuplat din maneta. Nu ca sa cuplezi, ci ca sa decuplezi planetarele de roti. Tico BMW 525d Mercedes 412 Terrano2 2.7 TD Link spre comentariu Distribuie pe alte site-uri Alte opțiuni partajare...
