8S9944 Turbine Holder.1,3,5 Remove nut (1). Position the compressor end of housing (5) in an oil bath so only impeller (3) is immersed in oil. Heat impeller to 350° F. (176° C.) for not longer than ten minutes. Remove unit from oil bath and press the shaft and turbine wheel from impeller (3).1,3,5 At installation, heat impeller (3) to a maximum of 350°F. (176°C.) for not longer than ten minutes and proceed as follows: For ease of impeller installation, place the turbine wheel end of center housing (5) in an 8S9944 Turbine Holder.a. Immediately install impeller (3) on shaft, install nut (1) and tighten it to 120 lb. in. (138,4 cm.kg).b. Allow impeller to cool to less than 150°F. (65, 49°C.) and remove nut (1).c. Clean and smooth the washer face of nut (1). Lightly oil the threads of turbine shaft and nut and install the nut.d. Tighten nut (1) to 20 lb. in. (23,0 cm.kg), then tighten an additional 120°.2 Coat threads with 9M3710 Anti-Seize Compound.4,5 Install thrust plate assembly (4) so oil hole aligns with oil hole in housing (5).
