Q: How to replace the rear crankshaft seal on 2012 and later Hyundai Accent?
A: First, take out the transaxle; next, you have to take out the flywheel/driveplate. Remove the Crankshaft Seal from the rear of the engine with the aid of a seal puller or a screwdriver in such a manner that one does not gouge or paint the crankshaft or the seal slot. Raise the block and clean the seal bore with a shop towel and make sure that there is no dirt or oil in it. Apply a little grease on the OD of the seal then slide it over the end of the crankshaft, making sure the lip is pointing toward the engine. If possible, with the separation vessel oriented the opposite from the original seal position, use a seal installment tool to press the new seal back into this location with the understanding that a small oil drain pipe in the separator must be at the bottom. In case the proper installation tool cannot be applied, then the use of a large socket will suffice in order to drive the new seal in such a manner that it will be parallel to the edge of the engine block. Finally, bolt on the flywheel/drive plate and then the transaxle.
Q: How to replace the front crankshaft seal on Hyundai Elantra?
A: To change the front crankshaft oil seal with the oil pump installed, follows the steps and take off the timing belt cover, timing belt, and the crankshaft sprocket. Observe the depth of the seal in the bore and then using screw driver or seal puller gently remove the seal from the oil pump housing without harming the crankshaft or scratching the housing. In the absence of a seal removal tool, two self-tapping screws are sufficient to thread into the front seal; this will help in pulling it out. Scrub the bore in the housing with a clean cloth and lubricate the outer/ridge part of the new seal in engine oil or multi-purpose grease with grease on the seal lip. Clamp the socket having slightly smaller outside diameter than the seal into place and hit the new seal gently to drive it in square and in the required depth as of the former seal. If a socket is not available a short piece of pipe of large diameter may be utilized. Once done fit the crankshaft sprocket, and make sure the slot of the timing belt fits properly over the spring before refitting the belt. All in all, start the engine and check the oil leakage dropping at the front seal. For the outer crankshaft oil seal RS, needed for 2011 and further year models, the crankshaft does not include a seal housing like models with an external housing Fast and Easy for the outboard crankshaft, the RS seal can be installed and removed without the housing. First, start with the removal of the transaxle, next, for the models having a manual transaxle, disassemble the pressure plate and clutch disc and lastly the flywheel or the driveplate. Using the seal removal tool, pry out the old seal up from the housing, put some clean engine oil on the lip of the new seal, using a large socket with a diameters slightly smaller as the outside diameter of the new seal, push the seal into the housing until it is fully in place. Check and reinstall the flywheel or driveplate Then for the Manual transaxle model reinstall the clutch disc as well as the pressure plate and again reinstall the transaxle main model.
