  Q: How to properly measure and install a crankshaft on Honda Fit?

  A:

  When removing crankshaft, check the end play with a crankshaft dial indicator placed in a position to touch the end of the crankshaft. Place the dial indicator at the rear of the crankshaft and rotate the component using a pry bar to zero it, followed by rotating the crankshaft to the front to read the endplay. If the endplay goes beyond these limits, the crankshaft thrust faces should be checked for wear after the pieces have been removed; if no signs of wear are observed, new main bearings should suffice. When a dial indicator is not available, use feeler gauges and push the crankshaft as far forward as possible and then slip the feeler gauges in between the crank-shaft and the thrust-bearing to measure the clearance. Slowly undo the cap bridge bolts until they hand accessible then remove the bolts and the main bearing cap bridge without dropping the bearing inserts. Come back with new bolts while keeping the old ones for the main bearing oil clearance measurement. Slowly raise the crankshaft out of the engine, and if you are working on the after 2009 model, you need to take out the Crankshaft Position Sensor pulse plate too. After inserting the bearing inserts, refit the bridge assembly back to the engine block and tighten the bolts with your fingers. To install the crankshaft, it is necessary to ensure that both the engine block and the crankshaft are clean and checked. The engine block should be set horizontally with the bottom up or turned slightly toward the horizontal, and then remove the main bearing cap bridge assembly. If there are worn but original bearing inserts left, take them out and make sure that the bearing surfaces are clear. It is recommended to clean the back-side of the new upper main bearing inserts and install them to the main bearing saddles with the oil hole alignment correct. Wipe and lay the lower main bearing inserts back to the main bearings and on the main bearing bridge, put the thrust washers at the right position. Scrub the faces of the bearing inserts and crankshaft main bearing journals, and look for dirt in the oil holes. After that, place the crankshaft into its lying position in the cylinder block and measure the main bearing oil clearance with the help of Plastigage and it should be slightly less than the journal width. Position Plastigage on each crankshaft main bearing journal, then install the main bearing cap bridge in the usual manner leaving the Plastigage undisturbed. Dip threads of bolts with clean engine oil before installation, then install the main bearing bridge bolts evenly without turning the crankshaft. Bolt reversal in an anti clock wise manner and then finally lift off the main bearing bridge, to check the width of Plastigage on the basis of scale in order to get the oil clearance. When the clearance is too large, investigate dirt or oil interference and replace the bearing inserts if needed. Try to remove any Plastigage that may have adhered to the journals and bearing faces without damaging those surfaces. For final installation, lift the crankshaft out, install the CKP pulse plate and bolts for 2009 and later models, then clean the bearing insert faces and apply a thin layer of grease or assembly lube. Replace the crankshaft back into its proper location and reinstall the Connecting Rod and caps for reassembly and clean the bearing insert faces before putting some liquid gasket on the lower main bearing bridge. Replace the bridge assembly or new bolts and securely tighten in accredited sequence. Recheck the crankshaft endplay and rotate the crankshaft with a running torque of 50 in-lbs or less to allow free movement. Lastly, fit the new rear main oil seal into its proper place or location as necessary or required.
