17 4 DLT ENGINE Fig. 9 Fig. 10 ENGINE DISMANTLING PROCEDURE (Engine mounted on the work stand) Removal of cooling fan Unstake lock plates and remove fan mounting bolts. Now remove fan along with hub. (Refer Fig. 9) Fig. 11 Removal of viscous drive fan (if fitted) Remove viscous fan mounting nuts & remove viscous fan assembly (Fig. 10) Observe following precautions while handling viscous fan. 1. The assembly viscous fan to be stored in the upside down condition. This is to prevent the silicone oils leakage through the oil seal. (Fig. 11) 2. While assembling / disassembling the viscous fan. Take proper care to avoid damages to bimetallic coil (located on viscous clutch housing towards radiator) 3. Care of viscous coupling to ensure lifelong trouble free service. a. The viscous coupling should not be cleaned with high-pressure water spray or steam cleaning equipment.The use of such high-pressure water / steam can cause damage to the bearing seal which allows water to enter the bearing.The presence of water in the bearing grease can cause corrosion and premature failure. b. The fan should be inspected during each scheduled servicing to ensure that none of the blades are damaged. Such damage can occasionally be caused if the stones or other foreign objects get thrown up from the road against rotating fan. Damage to the fan causes an imbalance situation which is detrimental to the fan clutch bearing, and inevitably shortens the life of viscous coupling unit.
