I will mount the bearings and crankshaft using cold and heat. If you cool a shaft of metal, it will shrink. Warming to a ballbearing, makes the hole in the ballbearing to expand. This I will use to get the ballbearings in place Picture 01 Rinse off the ballbearing with gasoline so it will be thoroughly clean NOTE Use gloves Picture 2 Blow the ballbearing with compressed air and put the ballbearing in a plasticbag Then place the bag with the ballbearing in the freezer overnight NOTE Do not let the balls spinning too fast Picture 3 Clean the crankshaft in the same way and put it in a plasticbag in the freezer Picture 4 Heat the block to about 100 degrees celsius (max 120 degrees) with a heatgun Tip Splash some water on the block if it sizzles, it's 100 degrees Picture 5 Picking up the ballbearing from the freezer cool down a bit more with the coolingspray Tip Let the ballbearing to rest a while before mounting and heat the block meanwhile Picture 6 Drop bearing straight down in block Tip If bearings stops - Tap on the outer edge of the bearing with a plastichammer Do the same with the ball bearing to the second block half Picture 7 Preheat your ballbearing in the big block half Picture 8 Now take the crankshaft out of the freezer and cool it a little extra Picture 9 Hold crankshaft straight and drop down into the block NOTE - Make sure you turn the crankshaft right path - Make sure the rod ends up in the right place Picture 10 I attach the crank assembly tool on the crankshaft Do not overtighten The tool aligns the crankshaft in the block Picture 11 Apply gasket sealant on the block Picture 12 Heat the ball bearing Picture 13 Cool crankshaft properly Tip Wipe off icecrystals from the crankshaft before installing Picture 14 Drop the blocks half at the crankshaft Picture 15 Tighten the bolts crosswise using a torque wrench Picture 16 Remove the alignment tool Picture 17 Check that the crankshaft rotates easily NOTE - Minimum chop makes ballbearings wear out prematurely - You may be required to center the crankshaft in the block if you pulled too much or too little with alignment tool - You can do this by pressing with a puller from either direction Picture 18 Lubricate the crankshaft and the bearing Picture 19 Grease sealings with grease and push on the shaft Picture 20 Press the bearings down with a pipestub Then do the same with the otherone Done!
