Transfer System (4WD): Other Lexus RX II

PRECAUTION

Note. When disconnecting the negative (-) battery terminal, initialize the following systems after the terminal is reconnected.

SYSTEM INSPECTION

1. Before disassembly, clean the transfer assy of any sand or mud to prevent it from entering inside the transfer during disassembly and assembly.
2. When removing any light alloy part such as a transfer cover, do not pry it off with a tool like a screwdriver, but tap it out with a plastic hammer instead.
3. Always arrange the removed parts properly and protect them from dust.
4. Before installation, clean and dry all parts completely, and then apply hypoid gear oil to each part. Do not use alkaline chemicals when cleaning aluminum, rubber parts, or ring gear set bolts. Also do not use any cleaning oil (ex. white gasoline) to clean the rubber parts such as O-rings and oil seals.
5. Apply hypoid gear oil to any sliding surface or rotating part.
6. Do not directly hold a part in a vise. Make sure to put an aluminum sheet between them.
7. Replace any damaged or deformed snap ring with a new one.
8. If there is a scratch on the contact surface of the case, it may cause oil leakage. Therefore, be careful not to damage the contact surface when handling it.
9. Before applying a sealant, completely remove any old sealant stuck on the parts and clean with white gasoline.
10. Do not add oil immediately after installing sealed parts. Leave for 1 hour or more.
11. Scratches on a contact surface of an oil seal, O-ring or gasket may cause oil leakage. Be careful not to damage the contact surface when handing the seals.
12. When press-fitting an oil seal, be careful not to damage the oil seal lip and around it.
13. When replacing a bearing, replace the inner and outer races as a set.

Scheme 115

1. INSPECT TRANSFER OIL Remove the transfer case No.1 plug and gasket No.1. Check that the oil level is 0 to 5 mm (0 to 0.20 in.) below the lower side of the transfer case No.1 plug hole. NOTE: When changing oil, recheck the oil level after driving. Excessively large or small amounts of oil may cause some trouble. When the oil level is too low, check for oil leakage. Tighten the transfer case No.1 plug with a new gasket No.1 Torque: 49 N.m (500 kgf.cm, 36 ft.lbf)
2. ADD TRANSFER OIL Remove the transfer case No.1 plug and gasket No.1 and add the oil. NOTE: When checking oil, make sure the vehicle is level. When adding oil, pour it slowly. Add oil several times in interval. HINT: Within 0 to 5 mm (0 to 0.20 in.) below the lower side of the transfer case No.1 plug hole. After leaving it alone for 5 minuites, recheck the oil level. Tighten the transfer case No.1 plug with a new gasket No.1. Torque: 49 N.m (500 kgf.cm, 36 ft.lbf)
