I was wondering:
When connecting rod failures occur, where does it usually happen? :think: I'm under the impression that it is usually the big end of the rod that fails, but I was wondering how frequently failures are seen at the small end, or somewhere in the middle for that matter.
The main reason I ask is that my 1995 KDX bottom end has about a zillion miles on it, but last time I had it apart, the big end side clearance was well within factory specs, and I couldn't feel any radial play. However, I could 'twist' the piston in the bore when the engine was assembled with the head off. The twist was a pretty significant amount, but I 'think' this is relatively normal with needle bearings.
So, does the small end of the rod ever wear out before the big end, or has anyone seen a small end failure of the rod?
Thanks,
Lutz
