GENERAL 7 1.2 RECOMMENDATIONS REPAIRS AND REPLACEMENT The following precaution and practices should be followed in order to reduce risk and conduct efficient and correct repair. 1. Go through the precaution and general infor- mation section given for that particular system or repair in this Workshop Manual. 2. Only TATA ARIA GENUINE SPARE PARTS should be used. Similar parts of other models should not be used, unless they have the same part number. 3. Do not use standard tools where special tools are recommended. 4. Whenever any hose is disconnected attach a tag to identify it. 5. Plug the ports, plugs and other openings of ag- gregates like FIP, TMC, etc. when remove from the vehicle. 6. When an assembly is dismantled, all reusable parts should be arranged in the sequence of its assembly in a clean enameled tray, in order to fa- cilitate the assembly. 7. Do not use jack to lift the vehicle for any jobs to be carried out beneath the vehicle, always use lifts. 8. Disconnect the battery before conducting any repairs. OIL SEALS NOTE Ensure that the seal is free from pits, scores, corro- sion and general damage prior to fitting replacement seal. 1. Always replace oil seals when rebuilding an as- sembly. 2. Carefully examine seal before fitting to ensure that it is clean and undamaged. 3. Coat the sealing lips with clean grease; pack dust excluder seals with grease. 4. Ensure that seal spring, if provided, is correctly fitted. 5. Place lip of seal towards fluid to be sealed and slide into position on shaft, using a fitting sleeve (5) when possible to protect sealing lip from damage by sharp corners, threads or splines. If the fitting sleeve is not available, use plastic tube or tape to prevent damage to sealing lip. 6. Grease outside diameter of seal, place on the housing and press into position, using great care and if possible a ’bell piece’ (6) to ensure that seal is not tilted. In some cases it may be prefer- able to fit seal to housing before fitting to shaft. Never let weight of unsupported shaft rest in seal. 7. If correct service tool is not available, use a suita- ble drift approximately 0.4 mm (0.015 in) smaller than outside diameter of seal. Use a hammer VERY GENTLY on drift if a press is not suitable. 8. Press or drift seal in to depth of housing if hous- ing is shouldered or flush with face of housing where no shoulder is provided. Ensure that the seal does not enter the housing in a tilted posi- tion. NOTE Most cases of failure or leakage of oil seals are due to careless fitting, and resulting damage to both seals and sealing surfaces. Care in fitting is essential if good results are to be obtained. Never use a seal which has been improperly stored or handled, such as hung on a hook or nail.
