Honda 8-94163-188-1 Crankshaft

The crankshaft can only be removed when the engine is removed from the vehicle; cautious, the following parts must be removedflywheel/driveplate, crankshaft damper/pulley, timing chain or belt, oil pan, oil pick-up, oil pump, front cover, and piston/connecting rod assemblies. Before the crankshaft can be pulled the rear main oil seal retainer must be removed as well as the bolts that secure the block. But first, make sure the endplay is correct; install a dial indicator, with the stem perpendicular to the crankshaft and touching the crank throw. Position the crankshaft to the rear and set the dial indicator to zero and then force the crankshaft to the front and read the indicator; the movement referred as endplay and should be adjusted using new main or thrust bearings if it exceeds standard measurements. In case a dial indicator is not available, feeler gauges can be applied in the following manner: one has to force the crankshaft forward and then turn it into the front direction and then use the feeler gauge to measure the space that is between the crankshaft and the thrust main bearing-this is the third one. Check that main bearing caps are identified for position from front to rear with progressive numbering and if not number them as required. Start on the main bearing cap bolts and rotate them to the point that they can be alternately unscrewed by hand the sequence of which is as follows; four-cylinder and v/6 engines. Tap with a soft-face hammer on the capings till they come off from the engine block for which the bolts can be used as levers. Finally, very gently lift the crankshaft out of the engine and with bearing inserts set back in place insert the steel caps back to the block with analyzing bearing upgrades & dynanmic squaring the head tighten the bolts only to finger tight.
