start by:a) remove turbochargers 1. Install the turbocharger on tool (A) as shown. Put marks on the three housings of the turbocharger for correct installation and alignment at assembly.2. Loosen clamp (1) and remove compressor housing (2) and the clamp from the cartridge assembly. 3. Loosen clamp (3) and remove cartridge assembly (4) from turbine housing (5).
To prevent a bent shaft, do not put a side force on the turbine shaft when the compressor wheel nut is loosened.
4. Install tool (C) in tool (B) and put the cartridge assembly in tool (C) as shown. Use tool (D) to remove the nut that holds compressor wheel (6). 5. Use a press to push the turbine shaft out of compressor wheel (6) and the cartridge housing. Remove compressor wheel (6) from the cartridge housing. 6. Put the turbine shaft in tool (C). Remove seal ring (8) and shroud (7) from the shaft.7. Use tool (E) to make sure the turbocharger shaft is straight. See SPECIAL INSTRUCTION Form No. SMHS6998. 8. Bend the tabs of the locks from bolts (10) and remove the bolts and locks.9. Remove backplate assembly (11) from the cartridge housing. Remove spacer (9) from backplate assembly (11). 10. Remove seal rings (12) from spacer (9). 11. Remove thrust collar (13) from the cartridge housing. 12. Remove seal ring (14) and thrust bearing (15) from the cartridge housing. If the bearings are to be used again, put identification on them as to their location for correct assembly. 13. Remove bearing (16) and the washer below the bearing from the cartridge housing. 14. Use tool (F) to remove snap rings (17) and (18) from the cartridge housing. 15. Remove bearing (19) and washer (20) from the cartridge housing.16. Use tool (F) to remove snap ring (21) from the cartridge housing if necessary.17. Check all the parts of the turbocharger for damage. If the parts have damage, use new parts for replacement. See SPECIAL INSTRUCTION Form No. SMHS6854 for TURBOCHARGER RECONDITIONING. Also see GUIDELINE FOR REUSABLE PARTS Form No. SEBF8018.Assemble Turbochargers (Airesearch TV61 And TW61)
1. Make sure all of oil passages in the turbocharger cartridge housing, backplate assembly and bearings are clean and free of dirt and foreign material.2. Put clean engine oil on all parts of the cartridge at assembly. Make sure the round edge of the snap rings are toward the bearings when the snap rings are installed. 3. If necessary, use tool (A) to install snap ring (1) in the turbine end of the cartridge housing.4. Install washer (2) and bearing (3). Use tool (A) to install snap ring (4) to hold the washer and bearing in the cartridge housing. 5. Use tool (A) to install snap ring (5) in the cartridge housing. 6. Install the washer and bearing (6) until the washer makes contact with snap ring (5). 7. Install thrust bearing (8) over the dowels in the cartridge housing. Make sure the grooves in bearing (8) are toward the outside as shown.8. Install seal ring (9) in the groove of the cartridge housing.9. Put thrust collar (7) in position on the thrust bearing with the counterbore for the spacer up. 10. Install seal rings (10) on spacer (11) so the gaps in the rings are 180° apart. 11. Install spacer (11) in backplate assembly (12) with the chamfer end of the spacer toward the cartridge housing.12. Make sure the oil passage in the cartridge housing and the backplate assembly are in alignment. Put the backplate assembly (12) in position on the cartridge housing.13. Install the locks and bolts to hold backplate assembly (12) to the cartridge housing. Tighten the bolts to a torque of 10 1.1 N m (90 10 lb.in.) and bend the tabs of the locks on the bolts. 14. Install tool (C) in tool (B). Put the turbine shaft in position in tooling (C). Put 6V2055 High Vacuum Grease in the groove for seal ring (14). 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 (14) and shroud (15) on turbine shaft (13). 15. Install the cartridge housing on the turbine shaft while spacer (11) is held in position. Make sure the seal ring on the turbine is fitted correctly in the cartridge housing.16. Put compressor wheel (16) in position on the turbine shaft.
Do not put a side force on the turbine shaft when the nut is tightened or a bent shaft will be the result.
17. Put a small amount of oil on the turbine shaft threads and the compressor wheel face that will be under the nut. Install the nut and tighten it to a torque of 13.6 N m (120 lb.in.) to push the compressor wheel (16) on the shaft. Loosen the nut and tighten it again to 3.4 N m (30 lb.in.). Tighten the nut 120° of a turn more. 18. Put the cartridge housing in a vise as shown. Check the shaft end play with tool group (D). The shaft end play must be 0.08 mm to 0.25 mm (.003 to .010 in.). 19. Install turbine housing (17) on tool group (E) as shown. Put the cartridge and clamp (18) in position in turbine housing (17). Make sure the marks on the housing and cartridge are in alignment and tighten clamp (18) to a torque of 13.6 1.1 N m (120 10 lb.in.). Lightly hit all around the clamp with a soft faced hammer and again tighten clamp nut to same torque. 20. Install clamp and compressor housing (19) on the cartridge in the correct position. Move clamp into position and tighten the nut to a torque of 13.6 1.1 N m (120 10 lb.in.). Lightly hit all around the clamp with a soft faced hammer and again tighten clamp nut to the same torque.end by:a) install turbochargers
