Front Crank Seal

The process of engine rear oil seal replacement begins with M/T transaxle manual transaxle assembly and A/T transaxle automatic transaxle assembly removal followed by clutch cover assembly and clutch disc assembly (M/T transaxle). To detach the drive plate and ring gear or flywheel begin by using Special Service Tool 09213-58012 (91111-50845), 09330-00021 to hold the crankshaft damper. Remove the engine rear oil seal by performing the following steps: cut off the oil seal lip with a blade then pry it out using a screwdriver covered in tape. Inspect the crankshaft for damage as the last step and round off rough edges with 400-grit sandpaper. The installation requires applying multipurpose grease to the new oil seal lip which must remain free of contaminants then using Special Service Tool: 09223-56010 with a hammer to tap the oil seal in position while observing a vertical alignment and wiping away any surplus grease from the crankshaft. Reinstall the drive plate and ring gear or flywheel by holding the crankshaft with Special Service Tool: 09213-58012 (91111-50845), 09330-00021, applying adhesive (Part No. 09330-00070, THREE BOND or equivalent) to the bolts, and tightening them uniformly in the specified sequence, with a torque of 88 Nm (900 kgf-cm, 65 ft. lbs.) for the drive plate (A/T) and 49 Nm (500 kgf-cm, 36 ft. lbs.) for the flywheel (M/T), ensuring not to reuse the flywheel bolts and marking them with paint before retightening by an additional 90 degrees and checking the paint mark position. The final installation steps include the clutch disc assembly for M/T transaxle along with the clutch cover assembly for M/T transaxle followed by manual transaxle assembly for M/T transaxle and automatic transaxle assembly for A/T transaxle. Complete inspection of engine oil leaks must be performed.

The replacement process for an engine rear oil seal begins by removing manual transaxle and automatic transaxle assemblies then moving on to the removal of clutch cover assembly and clutch disc assembly for manual transaxle. Detach the drive plate and ring gear or flywheel after using Special Service Tool: 09213-58012 (91111-50845), 09330-00021 to hold the crankshaft damper. Use a knife to cut the engine rear oil seal lip before extracting it with a taped screwdriver. Make sure to inspect the crankshaft for damage before sanding any rough surfaces with 400 grit sandpaper. The new oil seal receives multipurpose grease across its lip before installation with Special Service Tool: 09223-56010 and a hammer for tapping the seal until it reaches the rear oil seal retainer edge while maintaining a straight motion to avoid angles and wiping off all grease from the crankshaft. Reinstall the drive plate and ring gear or flywheel by holding the crankshaft with Special Service Tool: 09213-58012 (91111-50845), 09330-00021, cleaning the bolt and bolt hole, applying adhesive (Part No. 09330-0070, THREE BOND or equivalent) to the bolts, and uniformly tightening the 6 bolts for the automatic transaxle to a torque of 88 Nm (900 kgf-cm, 65 ft. lbs.) or the flywheel for the manual transaxle to a torque of 49 Nm (500 kgf-cm, 36 ft. lbs.), ensuring not to reuse the flywheel bolts, marking them with paint, and retightening by an additional 90 degrees while checking the paint mark position. After assembling the manual transaxle with automatic transaxle and clutch disc and clutch cover you should finish by inspecting for engine oil leakage.

Replacing the ENGINE REAR OIL SEAL (1NZ-FXE) begins with disassembly of the hybrid vehicle transaxle followed by removal of the transmission input damper assembly by using Special Service Tools: 09213-58013 (91111-50845), 09330-00021 to secure the crankshaft and unfasten the 6 bolts to extract the input damper and input damper cover. The procedure continues with removal of the flywheel sub-assembly while holding the crankshaft with the same tools. Afterward, the 6 bolts and flywheel become removable. To remove the oil seal begin by cutting off its lip with a cutter knife and gently prying it out with a screwdriver wrapped in tape while checking the crankshaft for damage followed by smoothing rough areas with 400-grit sandpaper when required. The installation of the replacement oil seal requires applying multipurpose grease No. 2 to its lip after clearing it from contaminants using Special Service Tool: 09223-56010 to tap the seal until it reaches the cylinder block edge with strict avoidance of angled tapping while removing all excess grease from the crankshaft. The assembly of the flywheel sub-unit requires adhesive (Part No. 08833-00070, THREE BOND 1324, or equivalent) on two or three bolt threads before placing the crankshaft between Special Service Tool: 09213-58013 (91111-50845), 09330-00021 for flywheel installation with six bolts that need to be tightened to 49 Nm (500 kgf-cm, 36 ft. lbs.) before each bolt receives an additional 90 degrees rotation. You must avoid starting the engine for a duration of 1 hour following the installation process. The hybrid vehicle transaxle assembly installation process ends with the transmission input damper assembly alignment using Special Service Tool: 09301-00210 along with temporary bolt tightening of the input damper cover and a second use of Special Service Tool: 09213-58013 (91111-50845), 09330-00021 for crankshaft holding before achieving 20 Nm (204 kgf-cm, 15 ft. lbs.) torque.

First, remove the manual transaxle assembly, automatic transaxle assembly, clutch cover assembly, and clutch disc assembly.

Apply multipurpose grease to the new oil seal lip, keeping it free of foreign materials, and use Special Service Tool: 09223-56010 and a hammer to tap in the oil seal until flush with the rear oil seal retainer edge, taking care not to tap at an angle and wiping off any excess grease.

Remove the transmission input damper assembly by holding the crankshaft with Special Service Tool: 09213-58013 (91111-50845), 09330-00021, and removing the 6 bolts to take off the input damper and input damper cover.
