When snap ring 4 is installed, hold it by hand to make sure that it does not bounce out.
(5) Removal of compressor coverA: Rubber hammer
* While using care to prevent damage to compressor cover 5, lightly strike its entire circumference with a rubber hammer A or similar tool.* Since the blades of compressor wheel 9 are readily bent, use care to make sure that they do not hit compressor cover 5.
(9) Compressor wheel[Removal]* Hold turbine housing 3 in a vice, and install wheel & bearing housing assembly 7.
Since the blades of shaft & turbine wheel 17 are readily bent, make sure that they do not hit the turbine housing 3.
* While holding down the boss on shaft & turbine wheel 17, remove lock nut 8. [Installation]* Hold turbine housing 3 in a vice and install temporarily assembled wheel & bearing housing assembly 7.
Since the blades of shaft & turbine wheel 17 are readily bent, make sure that they do not hit turbine housing 3.
* While holding down the boss on shaft & turbine wheel 17, apply MOLYKOTE to the threaded portion of lock nut 8, and tighten the lock nut to the specified torque. (10) Snap ring[Removal]
When snap ring 10 is removed, hold it by hand to make sure that it does not bounce out.
[Installation]* Install snap ring 10 in the illustrated direction in the bearing housing 22. A: Tapered surface
When snap ring 10 is installed, hold it by hand to make sure that it does not bounce out.
* Install snap ring 10 securely in the groove of bearing housing 22.B: HammerC: Screwdriver
Use care to make sure that plain screwdriver C does not hit bearing housing 22.
(11) Insert[Removal]A: Screwdriver [Installation]Install oil deflector 13 in the illustrated direction in bearing housing 22. (12) Measurement of clearance between open ends of piston ring* Mount a new piston ring 12 in insert 11.* Measure clearance A between the open ends of the piston ring.* If the reading is out of the nominal value, replace insert 11. (15) (16) Installation of thrust bearing, thrust ringInstall thrust bearing 15 and thrust ring 16 in such a way that they will be directed as shown. (17) Shaft & turbine wheel[Inspection](1) Bend of shaft * Using a dial indicator, measure at the illustrated position.* If the reading exceeds the limit, replace shaft & turbine wheel 17. (3) Rough journal If the journal is rough, repair by the following procedures.[Repair]* Install shaft & turbine wheel 17 on a lathe with both centers supported.* Lightly grind the journal through use of emery paper #400 and engine oil.
After the journal has been ground, be sure to measure the outside diameter of the journal.
(4) End play If the reading exceeds the nominal value, disassemble and check to locate the cause. (17) (18) Clearance between shaft & turbine wheel back surface and turbine back plate* Using two thickness gauges, measure the clearance at the end of blade.* If any reading exceeds the nominal value, disassemble and check to locate the
