How to remove and install front crankshaft seal in 3.0L and 3.6L V6 engine on GMC Terrain?

To remove the crankshaft pulley, first take it off and note the installation depth and orientation of the seal, ensuring the new one is installed the same way. Carefully pry the oil seal out of the cover; if a seal removal tool is unavailable, partially thread a self-tapping screw into the seal and use pliers as a lever to extract it. 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 rear using a hammer and punch, taking care not to scratch or distort the area where the seal fits to prevent leaks. For installation, 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 seal driver or a large socket and hammer to drive it into place, ensuring it enters squarely and is at the correct depth. Avoid getting oil on the rubber part of the seal or the crankshaft pulley contact area, as the seal must be installed dry. Check the pulley hub surface for grooves from prolonged contact with the seal; if damaged, replace the pulley. Lubricate only the inside of the pulley hub with clean engine oil before installing the crankshaft pulley, and complete the installation by reversing the removal steps.

How to replace the rear Crankshaft Seal in V8 engine on GMC Canyon?

If the rear Crankshaft Seal housing is to be installed on the engine block then special tools are required to place the housing block in the proper position over the end of the crankshaft since this alignment is most important since the seal if slightly off center is apt to leak. First, of course, must come the complete removal of the transmission and then the driveplate. Cautiously remove the Crankshaft Seal with a screwdriver using the flange of the crankshaft and inserted is the seal bore. As you can see how deeply the old seal is sunk into the housing bore the depth should be similar on the new seal and also the seal bore in the block should be thoroughly cleaned of any signs of oil & dirt. Lubrication of the seal and touching the sealing lip should also be avoided and the seal must be properly fitted with the part No. displayed. Probably the best recommendation is to use the seal installation tool which is used to push the new seal into its rightful position before the reinstallation of the driveplate followed by the transmission.

GMC Crankshaft Seal Parts Questions & Experts Answers

Seal, Crankshaft Front Oil
12584041
Q: How to remove and install front crankshaft seal in 3.0L and 3.6L V6 engine on GMC Terrain?
A: To remove the crankshaft pulley, first take it off and note the installation depth and orientation of the seal, ensuring the new one is installed the same way. Carefully pry the oil seal out of the cover; if a seal removal tool is unavailable, partially thread a self-tapping screw into the seal and use pliers as a lever to extract it. 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 rear using a hammer and punch, taking care not to scratch or distort the area where the seal fits to prevent leaks. For installation, 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 seal driver or a large socket and hammer to drive it into place, ensuring it enters squarely and is at the correct depth. Avoid getting oil on the rubber part of the seal or the crankshaft pulley contact area, as the seal must be installed dry. Check the pulley hub surface for grooves from prolonged contact with the seal; if damaged, replace the pulley. Lubricate only the inside of the pulley hub with clean engine oil before installing the crankshaft pulley, and complete the installation by reversing the removal steps.
Seal Kit,Crankshaft Rear Oil
89060436
Q: How to replace the rear Crankshaft Seal in V8 engine on GMC Canyon?
A: If the rear Crankshaft Seal housing is to be installed on the engine block then special tools are required to place the housing block in the proper position over the end of the crankshaft since this alignment is most important since the seal if slightly off center is apt to leak. First, of course, must come the complete removal of the transmission and then the driveplate. Cautiously remove the Crankshaft Seal with a screwdriver using the flange of the crankshaft and inserted is the seal bore. As you can see how deeply the old seal is sunk into the housing bore the depth should be similar on the new seal and also the seal bore in the block should be thoroughly cleaned of any signs of oil & dirt. Lubrication of the seal and touching the sealing lip should also be avoided and the seal must be properly fitted with the part No. displayed. Probably the best recommendation is to use the seal installation tool which is used to push the new seal into its rightful position before the reinstallation of the driveplate followed by the transmission.
