• Q: How to replace the Crankshaft Seal on 2005 Toyota Prius?

  A: The replacement of the ENGINE REAR OIL SEAL (1NZ-FXE) begins with hybrid vehicle transaxle assembly removal followed by removing the transmission input damper assembly by utilizing the Special Service Tools: 09213-58013 (91111-50845), 09330-00021 to stabilize the crankshaft while unfastening the 6 bolts which detach the input damper and input damper cover. The process continues with flywheel sub-assembly removal after securing the crankshaft similarly with the first tools. Afterwards extract the 6 bolts and the flywheel. A cutter knife should be used to cut off the oil seal's lip but the seal must be pried out using a tape-covered screwdriver while inspecting the crankshaft for damage along with smoothing any rough areas by using 400-grit sandpaper. Apply multipurpose grease No. 2 to the lip as a thin layer while protecting it from foreign materials and then use Special Service Tool: 09223-56010 to tap the oil seal until it reaches the cylinder block edge while avoiding angled tapping and removing remaining grease. After applying adhesive (Part No. 08833-00070, THREE BOND 1324, or equivalent) to the first 2 or 3 threads of bolt ends, make sure to clean all oil residue from bolts and bolt holes before attaching the flywheel with 6 bolts torque to 49 Nm (500 kgf-cm, 36 ft. lbs.) then every bolt requires an additional 90° of tightening. Do not start the engine during a 1-hour period after the installation procedure. To install the transmission input damper assembly position the hole of the input damper with Special Service Tool: 09301-00210. Use the 6 bolts to temporarily secure the input damper cover while holding the crankshaft with Special Service Tool: 09213-58013 (91111-50845), 09330-00021. Torque to 20 Nm (204 kgf-cm, 15 ft. lbs.) and reinstall the hybrid vehicle transaxle assembly.
