Saturn 14090906 Seal,Crankshaft Front Oil

Remove the crankshaft balancer and note how the seal is installed, ensuring the new one is positioned to the same depth and orientation. Carefully pry the oil seal out of the cover using a seal puller or a large screwdriver, taking care not to damage the crankshaft or distort the cover; wrapping electrician's tape around the screwdriver tip can help prevent damage. If replacing the seal with the timing chain cover removed, support the cover on two blocks of wood and drive the seal out from the backside using a hammer and punch, being cautious not to scratch or distort the area where the seal fits to avoid leaks. Apply clean engine oil or multi-purpose grease to the outer edge of the new seal and install it in the cover with the lip facing inward, using a large socket and hammer to drive it into place, ensuring it enters the bore squarely and stops at the proper depth. Check the surface on the balancer hub where the oil seal rides; if it is grooved, a press-on sleeve may be available to renew the sealing surface, which can be pressed into place with a hammer and a block of wood. Lubricate the balancer hub with clean engine oil and reinstall the crankshaft balancer, completing the installation in reverse order of removal.

Remove the timing chain cover, then use a punch to drive out the old oil seal and shedder, working from the front toward the rear of the timing chain cover. Apply the new oil seal packing around the opening with the ends positioned at the top, and drive in the new shedder using a punch, ensuring to stake it in place in at least three locations. Rotate the handle of a hammer or a similar tool to size the packing until the balancer hub can be inserted through the opening, and finally, re-install the timing chain cover.

Crankshaft pulley should also be unfastened and pay attention to how the seal is fitted, then repeat the same with the new one in terms of depth and position. Using a seal puller or a large screwdriver gently remove the oil seal from the cover without damaging the crankshaft or distorting the cover. In order not to mar the surface, an electrician's tape should be wound around the tip of the screwdriver. Use clean engine oil or multipurpose grease on outer periphery of new seal and fit the cover where this lip is to be inside. Tighten the seal centrally with a seal driver or a large socket and hammer, so that the seal fits the bore correctly and reaches the required depth before it is counter sunk. Over time an indentation or a groove may appear on the outer surface of the pulley hub where it has been in contact with the seal; a press-on sleeve is used to rebuild this sealing surface and this can be done using a hammer and a block of wood. Before installing crankshaft pulley clean the hub with some engine oil and fit the vibration damper installation tool to fix onto the crankshaft to press it into place. Last, fit the crankshaft pulley retaining bolt and torque it to the appropriate value and finally to complete in backward way of what was removed.

Remove the crankshaft pulley. Pry the old oil seal out with a seal removal tool or a screwdriver, being very careful not to nick or damage the crankshaft; wrapping the screwdriver tip with vinyl tape can help protect it. Apply a thin coat of ATV-type sealant to the outer edge of the new seal and lubricate the seal lip with moly-base grease or clean engine oil. Place the seal squarely in position in the bore and drive it into place with special tool J-35468 or an equivalent. If a special tool is not available, carefully tap the seal into place using a large socket or piece of pipe and a hammer, ensuring the outer diameter of the socket or pipe matches the seal's outer diameter, and confirm that the seal is seated completely in the bore. Install the crankshaft pulley and reinstall the remaining parts in the reverse order of removal. Start the engine and check for oil leaks at the seal.

After checking main bearing oil clearances, apply a thin, even coat of anaerobic-type gasket sealant to the indicated areas, avoiding contact with the bearing face, crankshaft journal, seal ends, or seal lips. Lubricate the seal lips with moly-base grease or clean engine oil.

Lubricate the seal lip with moly-base grease or clean engine oil.

First, remove the oil pan. Then, remove the bolts and detach the seal housing. Drive the old seal out from the back side with a punch and hammer.

Pry it out with a seal removal tool or a screwdriver, being careful not to damage the crankshaft.

The crankshaft journal should be checked for scratches and nicks.

You can replace the rear main bearing oil seal without removing the oil pan or crankshaft by following these steps: Remove the transmission. If equipped with a manual transmission, remove the pressure plate and clutch disc. Next, remove the flywheel or driveplate. Using a seal removal tool or a large screwdriver, carefully pry the old seal out of the block, being cautious not to scratch or nick the crankshaft.

If the seal bore has nicks and scratches, carefully smooth it with a fine file if necessary, but be careful not to nick the crankshaft in the process.

Drive the seal into place using a large socket and a hammer. If a large socket is not available, a piece of pipe will also suffice.

Install the special alignment tool (EN 47839) on the rear of the crankshaft, attaching it with the two supplied screws. Then, install the new oil seal housing over the alignment tool and studs onto the rear of the engine block, removing the guide studs but leaving the alignment tool in place.

Scratching or damaging the crankshaft sealing surface or the bore in the engine block can lead to oil leaks after the new seal is installed.

A large socket can be used to drive the seal squarely into the bore and flush with the rear cover.

Finally, install the driveplate and the transaxle.

A large socket, section of pipe, or blunt tool can be used to drive the seal squarely into the bore and flush with the rear cover.

Clean the seal bore thoroughly with a shop towel, ensuring all oil and dirt are removed.

Before reinstalling the timing chain cover, a bead of RTV sealant should be applied to the mating surface of the oil pan.

Check that the seal is seated squarely in the bore.

Check the seal journal for scratches and nicks before crankshaft installation, and remove the old seal from the housing using a hammer and punch, taking care to note its recessed depth for the new seal.

The initial components to be removed are the crankshaft pulley and the vibration damper.

A special tool is recommended for installing the new oil seal. Lubricate the lips of the seal with clean engine oil and slide the seal onto the mandril until the dust lip bottoms squarely against the collar of the tool.

A special aftermarket tool may be available at local auto parts stores to assist with this process.

Apply a thin layer of clean multipurpose grease.

Pry the old oil seal out with a seal removal tool or a screwdriver, being very careful not to nick or otherwise damage the crankshaft in the process.

Carefully push the new seal onto the crankshaft, using a smooth object to assist as you push the housing against the block.

Install a new rope seal into the main bearing cap groove, pushing firmly all around using a hammer handle or special GM tool. Ensure the seal is firmly seated, then trim the ends flush with the bearing cap mating surface.

The first step is to remove the cable from the negative battery terminal.

A thin coat of RTV-type sealant should be applied to the outer edge of the new seal, and the seal lip should be lubricated with moly-base grease or clean engine oil.

Clean the bore in the block and the seal contact surface on the crankshaft, checking for scratches and nicks that could damage the new seal lip and cause oil leaks. If the crankshaft is damaged, a new or different crankshaft is necessary.

Disconnect the negative battery cable from the battery.

Install the housing bolts and tighten them to the specified torque before removing the alignment tool.

Install the crankshaft pulley retaining bolt and tighten it to the specified torque, completing the installation in reverse order of removal.

All surfaces should be lubricated with a small amount of engine oil before installing the seal.

Secure the tool to the crankshaft using the provided bolts and install the seal by rotating the tool's "T" handle until the collar bottoms against the block, then remove the tool.
