Q: How to install rear Crankshaft Seal on Honda Del Sol?
A: The new Crankshaft must be put in place and the main bearing caps tightened before putting into place the new Crankshaft Seal and its retainer on the block. First, start unlatching the old sealing by putting a hammer and a punch and pull the seal out from the back side with the help of wooden blocks from below the retainer. It is recommended to observe the amount of inset that the old seal is from the new retainer bore, because the new Crankshaft Seal should inset the same distance. Do not scratch or damage the bore in order to stop the oil leak. Check that the retainer is clean and then place a drop of engine oil to the outer lip of the new Crankshaft Seal. Place the seal well into the retainer bore and in case of press being unavailable, place the retainer and the seal between two wooden blocks and use a large vise to force the desirable seal into the retainer bore. In the other case, place the retainer on a workbench and force the Crankshaft Seal into the bore with a wooden block and a hammer, so that the seal enters the bore in a square manner. You also need to double check using a feeler gauge to ensure that the clearance from the seal to the retainer is the same all the way round. Running a layer of RTV sealant about 1/32 of an inch thick along the whole periphery of the retainer should suffice. Generously apply multi-purpose grease or engine oil on the seal lips and place the seal/retainer over the crankshaft and screw it onto the block securing it with a new gasket that has RTV sealant applied on one side of the gasket and the block surface where the seal/retainer is to be fitted. Last but not the least, slowly and gradually tighten the retainer bolts up to the said torque and then cut off the extra length of the gasket with the help of wire cutters or a small hacksaw and ensure that the gasket surface on the oil pan does not get scratched.
