Place backplate (16) in vise with soft jaws.
Check thrust float with dial indicator. Move shaft
(21) back and forth in center housing (5).
Indicator reading (thrust float) must be
0.003 to 0.010-in. (0.08 to 0.25 mm).
Align matchmarks on center housing (5) and turbine housing (25).
Install turbine wheel assembly (26) in turbine housing (25) and coupling (27).
Apply high temperature antiseize compound (Item 4, Appendix 4) to threads of screw (28).
Do not tighten turbine housing clamp until center housing is
