Toyota 90311-A0005
Oil Seal, Front

Starting the replacement of the 1GR-FE front crankshaft seal requires users to disconnect the negative terminal battery cable. Begin by removing the V-bank cover after which the radiator support seal upper must be detached through 11 clip removal. Untie the sub-assembly of the No. 1 engine under cover by unbolting its four fasteners. Begin by loosening the fan with fluid coupling and then uninstall the fan along with the generator V belt followed by removal of the fan coupled with fluid coupling. The removal of the crankshaft pulley requires Special Service Tools 91651-60855, 09213-54015, 09950-50013, 09330-00021, 09951-05010, 09952-05010, 09953-05020 and 09954-05031. The timing gear case or timing chain case oil seal extraction requires a screwdriver tool to pry it out while the screwdriver tip should have tape coverage to safeguard the crankshaft from damage.

The crankshaft main bearing seal service and repair procedure demands first disassembling the automatic transaxle assembly followed by both drive plate and ring gear or flywheel removal. Special Service Tools 09213-70011 (09213-70020) and 09330-00021 should be used to hold the crankshaft before you remove its 8 bolts and front spacer and drive plate and 10mm298.95968 lock ring and rear spacer. Begin by using a knife to cut off the oil seal lip then gently remove the oil seal from the engine rear with a taped screwdriver to avoid wrecking the crankshaft. Install the new oil seal by applying MP grease to its lip before striking it into the housing with Special Service Tool: 09223-15030, 09950-70010 (09951-07150) and a hammer to a depth of -0.5 to 0.5 mm (-0.020 to 0.020 in.). Install the drive plate and ring gear or flywheel by applying adhesive to two or three threads of the mounting bolt end using Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent. Complete the installation by holding the crankshaft with Special Service Tool: 09213-70011 (09213-70020). Before tightening the 8 mounting bolts apply Toyota Genuine Adhesive 1324 or Three Bond 1324 or equivalent to 2 or 3 threads of each bolt end using Special Service Tool: 09213-70011 (09213-70020). Place the crankshaft spacers in order with drive plate and rear spacer before performing bolt torque to 83 N m (850 kgf/cm, 61 ft. lbs.) with even steps. The automatic transaxle assembly should be reinstalled at the end of the task.

The repair and service operation for the front crankshaft seal in 2UZ-FE requires several necessary components which should be prepared first. Prepare all necessary tools and replacement parts before starting the front crankshaft seal repair work on the 2UZ-FE engine. Clear the path toward the seal before extracting the old component with careful attention to adjacent parts. A complete cleaning of the sealing surface is crucial before inserting the new seal where it should align properly. After reinstallation of all taken components users should inspect for leakages as a verification of the successful maintenance procedure.

A new oil seal requires MP grease application to its lip before installation. Special Service Tool: 09223-22010 09506-35010 combined with a hammer should be used to tap the oil seal between 0 and 1.0 mm (0 and 0.0394 in.) depth from the timing chain cover edge while maintaining both lip cleanliness and avoiding angular impacts on the seal. Afterward install the crankshaft timing gear key then put on the crankshaft pulley. After applying MP grease to the oil filter bracket and oil cooler you must install them together. Additionally you should install the No. 1 oil cooler bracket with its associated oil cooler. The No. 2 water by-pass pipe sub-assembly can be connected through attaching two water by-pass hoses to the oil cooler followed by installation of three by-pass pipe bolts with 10 Nm (102 kgf-cm, 7 ft-lbf) torque. The installer should first attach the cooler compressor components then proceed with the bracket installation of the oil filter which does not include the oil cooler as well as the oil pressure sender gauge assembly and fan shroud. After hose installation on the No. 1 radiator hose add engine coolant before inspecting the vehicle for leaks at coolant and oil components and checking the engine oil level. The assembly requires installation of the V-bank cover sub-assembly together with the No. 1 engine under cover sub-assembly and front fender splash shield sub-assembly for each left and right side.

New oil seals must start with an application of MP grease to their lips before installation while avoiding both foreign material contact with the lip and grease contact with the dust seal. Special Service Tools 09223-15030 and 09950-70010 should be used together with a hammer to drive the oil seal until its surface matches cylinder block and crankcase dimensions while maintaining a secure position that separates the lip from foreign materials and excludes angled impacts. Clean both bolts and their installation holes before adding a few drops of Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent to the bolt end up to 2 or 3 threads. Begin by attaching the front drive plate spacer while guiding its pin into the crankshaft pin hole. Position the drive plate and rear drive plate spacer before torquing the eight installation bolts to 98 Nm. Apply Toyota Genuine Adhesive 1324 or Three Bond 1324 or equivalent to 2 or 3 threads of bolt ends before installing and evenly torquing the specified 8 bolts to 98 Nm (999 kgf-cm, 72 ft-lbf) while being cautious about drive plate installation bolt damage. The automatic transaxle installation requires three essential steps according to the vehicle 2WD or 4WD specification. The procedure requires you to first install both the engine and the transaxle. A cable needs connection to the negative terminal before running the Reset Memory procedure on U241E for 2WD or U140F for 4WD.

Before you install the front crankshaft oil seal you need to apply MP grease to its lip on the new oil seal. A hammer and the Special Service Tools: 09316-60011 and 09316-00011 should be used to tap the oil seal into position until its surface level matches the oil pump body edge while avoiding angled impacts and ensuring no contaminants enter the included lip section. The installation requires Special Service Tool: 09223-46011 and a hammer to tap the timing pulley in while using the set key to align it with the pulley's key groove with the flange side facing towards the inside. Connect the cable to the negative battery terminal with it requiring 5.4 Nm torque (55 kgf-cm, 48 in-lbf) while some systems may require initialization after reconnection. The technician should inspect for leaks of engine oil and coolant and fuel along with measuring engine oil level and checking ignition timing and engine idling speed. The installation procedure ends with the fitting of engine under cover No. 1.

Starting the procedure of removing the front crankshaft seal from a 2GR-FE engine begins with removing the right-hand side front wheel along with the right-hand front fender apron seal. Removal of the V-ribbed belt comes after the initial steps. Special Service Tools 09213-70011 and 09213-70020 must be used to lose the crankshaft pulley bolt. Apply Special Service Tools: 09950-50013 alongside 09951-05010 to eliminate the crankshaft pulley bolt and then its accompanying pulley from the system. Use a screwdriver to extract the timing chain case oil seal while taping the screwdriver tip ahead of time. Examine the crankshaft for damage before proceeding with installation.oplayer bolt.
