Hi, Any opinions on the picture?

The picture shows the inner race on the timing side of the crank. The surface has given way to about 2/5 of the circumference of the race, rollers ok, but cage did fall apart on splitting the cases. No signs of heat. Main bearings and the rest ok.


Pearson crank
GP50 oil
Good oil pump
2k miles
10 thou end float
SKF bearing (Pearson fitted)

My friend has had the same issue with the same spec?

Many thanks
