Interesting photos.

I=E2=80=99ve never thought about this. All my cranks need a little =
straightening after some use in race engines.

The machine shop says, that is normal. Many race engines warp cranks =
during usage.

As long the bearings are okay nothing to do they say.

My mains never developed a problem=E2=80=A6..and I=E2=80=99m running =
larger main bearing clearances to compensate crank flexing=E2=80=A6.all =
seems fine.

On the other hand, I=E2=80=99m running smaller rod bearing clearances.

Has anyone seen the need to add extra support to the center main on the =
TR wet sleeve engine? We have an engine that has a steel bridge =
cross-bolted underneath and supporting the center main cap. Is this =
needed? Just took 3 factory cranks to the machine shop and all three =

first and last mains.) Two of these were raced, the third was removed =

Curious as to the need for the extra support.
