Timing Cover, Upper Outer

Start the timing cover replacement process by removing the front wheel RH followed by the front fender apron seal RH, engine cover sub-assy No.1 and engine moving control rod with bracket by uninstalling its 3 bolts and then remove the engine mounting stay No.2 RH and engine mounting bracket No.2 RH. After using Special Service Tool: 09249-63010 you can remove the fan and generator V belt followed by the crankshaft pulley. Follow these steps to take off the pulley bolt of TMC-made pulleys: Use Service Tool 09213-54015 plus 91651-60855 and Special Service Tool 09330-00021, then employ Service Tool 09950-50013 to remove it together with its components 09951-05010, 09952-05010, 09953-05020, and 09954-05021. The tightening and removal of TMMK made pulley bolts requires Special Service Tool 09960-10010 (09962-01000, 09963-01000) and Special Service Tool 09950-40011 (09951-04010, 09952-04010, 09953-04030, 09954-04010, 09955-04041, 09957-04010, 91111-51014). The timing gear case or timing chain case oil seal can be removed through seal lip cutting and screwdriver scraping. Check the crankshaft condition after removal by utilizing sandpaper (#400) when required for repair. Use Special Service Tool: 09223-22010 along with a hammer to install a new oil seal by applying MP grease to its lip while making sure no foreign matter remains inside the lip. Deepen the lip into the rear oil seal retainer edge before wiping off excess grease from the crankshaft. Reinstall the crankshaft pulley while aligning the pulley set key to the key groove by using Special Service Tool: 09213-54015 (91651-60855), 09330-00021 for TMC made or Special Service Tool: 09960-10010 (09962-01000, 09963-01000) for TMMK made and tightening the pulley bolt to 170 Nm (1,733 kgf-cm, 125 ft. lbs.). First reinstall the fan and generator V belt using Special Service Tool: 09249-63010 and proceed to bolt the engine mounting bracket No.2 RH at 52 Nm (531 kgf-cm, 38 ft. lbs.) followed by tightening the engine mounting stay No.2 RH to 64 Nm (653 kgf-cm, 47 ft. lbs.) before securing the engine moving control rod with bracket by tightening its 3 bolts to 64 Nm (653 kgf-cm, 47 ft. lbs.). To complete the repair the mechanic should reinstall the front wheel RH at 103 Nm (1,050 kgf-cm, 76 ft. lbs.) before checking for oil leaks.

The replacement process for timing gear case or timing chain case oil seal begins by dismissing bolts from the front wheel RH and engine moving control rod with bracket, front fender apron seal RH and engine cover sub-assembly No.1. The procedure starts by removing engine mounting stay No.2 RH and engine mounting bracket No.2 RH. Then the sequence continues with fan and generator V belt before removing them both. Special Service Tool enables the removal of the crankshaft pulley bolt along with its pulley after bolt loosening. The oil seal on the timing gear case or timing chain case should be removed using Special Service Tool: 09308-10010, 09950-60010 (09951-00200). The installation procedure begins with applying MP grease to the lip of a new oil seal while keeping it clear of external contaminants before using Special Service Tool: 09223-22010 and a hammer to tap the oil seal until the surface reaches the rear oil seal retainer edge followed by wiping off excess grease from the crankshaft. Install the crankshaft pulley by positioning its set key into the key groove then securing it with the pulley bolt at 170 Nm (1,733 kgf-cm, 125 ft. lbs.). Follow with installation of the fan and generator V belt along with engine mounting bracket No.2 RH and engine mounting stay No.2 RH according to their respective torque specifications of 52 Nm and 64 Nm. The installation process requires attachment of the engine moving control rod with bracket through its 3 bolts to a torque of 64 Nm (653 kgf-cm, 47 ft. lbs.). Afterward replace the front wheel RH and verify there are no engine oil leaks.

Starting the replacement process of the timing gear case or timing chain case oil seal begins by removing the front wheel RH alongside the front fender splash shield front RH, front fender apron seal RH, engine cover sub-assy No.1, engine mounting stay No.2 RH, engine moving control rod with bracket, engine mounting bracket No.2 RH, fan and generator V belt, and crankshaft pulley. You must detach the existing oil seal by utilizing Special Service Tool: 09308-10010 and 09950-60010 (09951-00200). Add MP grease to the lip of a new oil seal before using Special Service Tool: 09223-22010 and a hammer to tap in the oil seal until its surface reaches the rear oil seal retainer edge. Afterwards wipe the crankshaft clean of excess grease. The crankshaft pulley and fan and generator V belt installation requires 52 Nm of torque (531 kgf-cm, 38 ft. lbs.), and then engine mounting bracket No.2 RH and engine mounting stay No.2 RH receive torques of 52 Nm (531 kgf-cm, 38 ft. lbs.) and 64 Nm (653 kgf-cm, 47 ft. lbs.). The last procedure involves mounting the engine moving control rod and its bracket as well as reinstalling the front wheel on the right-hand side while testing the engine for oil leaks.

Begin the procedure to replace the timing gear case or timing chain case oil seal by unbolting the three clips from the front wheel RH and the front fender apron seal RH along with the engine cover sub-assy No.1 and engine moving control rod with bracket. The replacement process begins by taking out engine mounting stay No.2 RH and engine mounting bracket No.2 RH and progressing to fan and generator V belt elimination. First loosen the crankshaft pulley bolt with Special Service Tool: 09960-10010 (09962-01000, 09963-01000) before removing it with Special Service Tool: 09950-40011 (09951-04010, 09952-04010, 09953-04030, 09954-04010, 09955-04041, 09957-04010, 91111-51014). Use Special Service Tool: 09308-10010 and 09950-60010 (09951-00200) to extract the timing gear case or timing chain case oil seal. Installation begins with applying MP grease to the new oil seal against its lip and ensuring foreign substances stay away. Special Service Tool: 09223-22010 together with a hammer allows personnel to tap in the oil seal until it reaches flush with the rear oil seal retainer edge before wiping off excess grease from the crankshaft. The crankshaft pulley reinstallation requires alignment of the pulley set key with its key groove while using Special Service Tool: 09960-10010 (09962-01000, 09963-01000) to insert the pulley bolt until it reaches 170 Nm (1,733 kgf-cm, 125 ft. lbs.) torque. The service procedure includes reattaching the fan and generator V belt and engine mounting bracket No.2 RH along with its specific torque of 52 Nm (531 kgf-cm, 38 ft. lbs.) and adding engine mounting stay No.2 RH with 64 Nm (653 kgf-cm, 47 ft. lbs.) torque followed by engine moving control rod with bracket bolt attachment torque at 64 Nm (653 kgf-cm, 47 ft. lbs.). The last step requires reinstalling the right-hand front wheel followed by a leak inspection of engine oil.

Use 3 bolts and a torque of 64 Nm (653 kgf-cm, 47 ft. lbs.).

Reinstall the front wheel RH, torquing it to 103 Nm (1,050 kgf-cm, 76 ft. lbs.), and conclude by inspecting for any oil leaks.

Reinstall the engine moving control rod w/bracket, front wheel RH, and check for engine oil leaks.

Remove engine mounting stay No.2 RH and engine mounting bracket No.2 RH, followed by the fan and generator V belt.
