Big ends

(28-04-2021, 10:17 PM)Chris KC Wrote: I'm no expert on white metal bearings nor the fitting thereof, but I do think the rods and caps must seat together properly under bolt tension and if that's not the case it should be addressed before any foray into bearing scraping. If the two halves of the rod have a visible gap between them trouble will follow.

Just to add to Chris's comment above, many big end caps will have been filed in the past to reduce clearance to the crankpin. Sometimes the caps have more filed of one side than the other. So it is well worth checking that the cap seats nicely on the rod before tightening the nuts down; otherwise the resulting bending load on the big end bolt(s) is asking for an expensive failure when the motor is run.
