I just want to get some seasoned engine builder's opinions and experience on replacing bearings, where you get the parts from, and how much they were. Currently, Im looking at $8 and $10 per bearing shell.I am re-assembling a motor and am torn on whether to replace the bearings while I'm in there. The bearings look good, measure up a little on the loose side. This was a race motor, I don't believe it had too many miles on it. Its prolly about a 90hp motor. Its got Carillo Rods, bumpy cam, porting, and is an 811cc motor. I won't be racing this motor, just running it hard on backroads and whatnot.Do you think these bearings will hold up?
If its got non Honda rods the chart wont work unless you got superacurate measuring kit
Use plastigauge to measure the clearances. I just bought a stick for less that $5 and had enought to do all 9 journals. Clean the bearings, clean the journal, cut the gauge, torque to specs and remove and read the width of each stripe - and you're ready for ordering.Be careful torquing those Carillos to 52. I just bought a new set and mine says "Do not exceed 45 lbs" You've after bolt stretch of .005~.007 and mine occured at 35 lbs on the dot.Regards,Gordon
According to the chart, I need Browns for the cases and Greens for the rods. But since my pins seem .005 smaller, I wonder if I should go a step thicker on the bearings, to Black/Brown instead of Brown/Green? The bearings that are currently in place are both a dark color.
