Are big end and main bearings the same from 1850 and TR7 ? and where's best to buy them from

Yes they are.

Tri-Metal are the best, look for brands such as Vandervel, Glacier AE or Clevite. I have some sizes of these on the shelf

New old stock come up from time to time on ebay, or you could chance King brand though often you'll find County brand in King boxes...

Thanks, cant see any sizes on the original bearing there VP so think they must be standard size, if you have both big ends and mains tell me know

thanks Dave

Just a Quick thought can a crankshaft bend slightly but still turn okay, my reasons are number 3 big end bearing is worn a little looks as if it got warm ? and number 3 main bearing is a very loose fit in the main cap ?

All other bearings look okay ?

Yes and easy to correct with a big hammer.

Usually oversized bearings are marked as such, some brands also mark standard as such, so it sounds as if your's are standard; if in doubt, measure the crank journal diameters. They should be 2.1260 to 2.1265 inches for the mains and 1.75 to 1.7505 inches for the crankpin.

I have Australian made BapGeon brand bearings for the big ends and Israeli made (better quality old stock) King brand for both in standard size
