What is the normal practice in terms of inspecting the case halves prior to a rebuild? Is this something I can do myself?
All the bearing surfaces looked fine and the connecting rod play was between .008 and .010. Assuming I don't see any visual signs of damage, does it need to be sent to a professional who I assume has an expensive tool that checks the alignbore? |

If you have a dial bore gauge you can measure the bore to check for diameter and how round they are. This should be done under torque.
I have seen builders with a lot of experience use a #2 bearing and press it into the saddles as a screen for good cases. It should be pretty tight. I don't have enough experience myself to trust this. Jake has a trick he uses to check for collapse. Follow this Link and he mentions it. You can mock up the build with the crank and bearings and measure bearing clearance with Plastigauge. Personally, I would get some help if you are not sure. The downside risk with a mistake here are just too great. Dave |
