560XP Crank Bearings

[Macpherson]

many older engines had a roller on the drive side and a ball on the other which held the crank in the correct position, however that`s irrelevant when it comes to the 560xp. It remains a mystery !!

I feel there is nothing wrong with the bearing, the cage is there to keep the balls apart, if the cage breaks up it is because it was the way it was fitted ie stressed and loaded up, when you rebuild and engine and do the final tighting of the crankcase screws you need to give a tap on either side of the crank ( copper hammer ) to releave any side loading.

 

Very true, caught me out the first time:blushing:

Agree on your assembly technique  to help side loading .

Have changed many of these and primary reason for failure is absence  of the cage then radial movement  destroying seals,
