See the Operation & Maintenance Manual.Disassemble Turbocharger (Marine Engine)
Start By:a. remove turbocharger 1. Install the turbocharger on Tooling (A). Put marks on the three housings of the turbocharger for correct installation and alignment at assembly.2. Loosen "V" clamp (2), and remove compressor housing (1). 3. Loosen "V" clamp (3), and remove cartridge housing (4) from turbine housing (5). 4. Put the cartridge assembly in Tool (B) as shown.
When the nut is loosened, do not put a side force on the shaft.
5. Use Tool (C) and a universal socket, and remove the nut that holds compressor wheel (6).
Compressor wheel (6) has sharp edges and can cause personal injury if not handled carefully.
6. Put the cartridge assembly in Tool (D), and use a press (if necessary) to remove compressor wheel (6) from turbine wheel and shaft assembly (7). Do not let the turbine wheel and shaft assembly fall during removal of the compressor wheel.
The turbine wheel has sharp edges and can cause personal injury if not handled carefully.
7. Remove seal ring (8) and shroud (10) from turbine shaft (9). 8. Use Tool (E), and remove ring (11) that holds insert (12) on the cartridge housing. 9. Remove insert (12) with Tooling (F). 10. Remove O-ring seal (14) and sleeve (13) from insert (12). Remove the seal ring from sleeve (13). 11. Remove deflector (16) and ring (15) from the cartridge housing. 12. Remove bearing (18), sleeve (17) and the ring from the cartridge housing. 13. Use Tool (G), and remove ring (20). Remove bearing (19), and put a long dye mark on the top of the bearing. 14. Turn the cartridge assembly over. Use Tool (G), and remove ring (21). Remove bearing (22) from the cartridge housing, and put a short dye mark on the top of the bearing. The dye marks are used for identification of the bearings when they are installed.15. If necessary, remove the two rings that hold the bearings in position from the cartridge housing with Tool (F).16. Check all the parts of the turbocharger for damage. If the parts have damage, use new parts for replacement. See Special Instruction, SMHS6854, for Turbocharger Reconditioning. Also see Guideline For Reusable Parts, SEBF8018, and Analyzing Turbocharger Failure, FEG45138. Assemble Turbocharger (Marine Engine)
1. Make sure all of the oil passages in the turbocharger cartridge housing are clean and free of dirt and foreign material.2. Put clean engine oil on all parts of the cartridge assembly.3. Make a replacement of the two inside rings that hold the bearings in position in the cartridge housing if necessary. Install the rings that hold the bearings in position with the round edges of the rings toward the bearings. 4. Install bearing (2) in the cartridge housing.5. Use Tool (A) to install ring (1) in the cartridge housing. 6. Turn the cartridge assembly over, and install bearing (4). Use Tool (A), and install ring (3) to hold the bearing in position. 7. Install ring (7), sleeve (6) and bearing (5) in the cartridge housing. Make sure the oil hole in bearing (5) is open and clean to prevent a bearing failure. 8. Install ring (9) and deflector (8) in the cartridge housing. 9. Install O-ring seal (12) around insert (11).10. Put 6V-2055 High Vacuum Greaseon the seal ring.11. Install sleeve (10) in insert (11) from the bottom side. 12. Install insert (11) in the cartridge housing. Use Tool (B), and install the ring to hold the insert in position. 13. Put turbine shaft (14) in position in Tool (C). Put 6V-2055 High Vacuum Greasein the groove for seal ring (15). Make sure the grease fills the groove approximately one half or more of the groove depth for the complete circumference of the groove to help make a carbon dam under the seal ring. Install seal ring (15) and shroud (13) on turbine shaft (14).
