What would be the correct configuration on rollers on my 61 G80cs big-end Ive seen different articles e:g 3 rows of ten 1/4" x1/4," 28 1/4"x1/4"or 14 1/2"x1/4"rollers.Also has anyone had dealings with ALPHA bearings is there chance they might stock the right one.

The original configuration was two long rollers per row on short stroke motors & there short ones on long stroke. I suggest you find an engineer familiar with the engine & fit the big end correctly. Don.
