Discussion and questions related to the course Practical Engine Building
When setting bearings on con rods, if i ran the (red bearing) thinnest Honda bearing and clearance is at 0.0017" and wanted to set rod bearings at 0.0023". Would i have any issues with honing cond rod big end a couple tenths?
What's the max i can take off before having bearing crush becomes an issues?
Cranke Rod Journal = 1.8898"
Street car/Nitrous = 300whp
a couple of tenths is not an issue on a new rod I would not be so quick to think that if it was a used rod
Not sure if you realise this is one of multiple posts on the same subject, Ross.
I had advised against this option because that is a loss of ~2 thou total crush, and if it's already close to the upper limit, it's quick ride to a spun bearing.
What I had suggested was either purchasing an oversized bearing set (+ 0.001 on nominal, preferably 1 rod set), if available, or having the journal polished which is a much simpler, and cheaper option.
