Question 1

What precautions should be taken regarding the front Crankshaft Seal when removing the timing belt and crankshaft sprockets to prevent four-cylinder engine damage on Mitsubishi Galant?

Accepted Answer

Do NOT rotate the camshaft(s) or crankshaft with the timing belt removed; engine damage may occur. This task requires expert assistance. Commence with the disassembly of the timing belts and the front crankshaft sprocket. Employ a bolt-type gear puller in order to ease the crankshaft sprocket from the crankshaft and lift the Woodruff key. Take a small screwdriver and wrap the tip with some tape. You now want to pry the seal from its bore with this screwdriver. Just make sure you do not mar the front case, crankshaft or seal bore while you do this. Clean and inspect the surface of the seal bore and the crankshaft sealing surface. Minor blemishes can be removed with emery cloth. If a groove is worn on the sealing surface, a new seal may not stop the leak. Using the hammer, install the new seal in the crankshaft, which must be lubricated with engine oil. This will help the oil seal drive smoothly. The subsequent steps consist of reversing the sequence of removal of the crank sprockets and the CKP sensing blade, located between the two sprockets, while adhering to the process for degreasing the sensing blade and sprockets. Finally, start the engine and check for any leaks.

Question 2

How is the one-piece rear main Crankshaft Seal installed in the four-cylinder engine on Mitsubishi Galant?

Accepted Answer

The bore machined into the rear main bearing cap and engine block contains the one-piece Crankshaft Seal that is pressed in. To start with, you need to remove the transaxle, the clutch components if any, and the flywheel or you may call it a driveplate. Make sure that the oil seal is flush with the outer face of the block. Use a 3/16-inch flat blade screwdriver to carefully pry out the old seal. Take care not to nick or scratch the crankshaft or seal bore. Ensure the crankshaft sealing surface or the bore in the engine block is not scratched to avoid oil leak after fitting a new seal. Giving all shaft and seal bore a good clean with the lacquer thinner or acetone with a rag will degrease both the crankshaft and seal bore areas. Do not lubricate the lip or outer diameter of the new seal. This must be installed as you take it from the manufacturer. Alternatively, fit the new seal onto the crankshaft so that the words THIS SIDE OUT, if marked, face out towards the rear of the engine. Turn the seal into the cylinder block using a suitably sized driver and pilot tool until it is flush with the outer surface (do not drive it in past flush, or an oil leak will result). Installation to be performed in reverse order of removal.
