915 Gearbox Pinnion Bearing Orientation
Question on the orientation of the pinnion bearing I'm planning to refit tomorrow. Because the old bearing lost its cage I'm not 100% sure of the bearing orientation. Bentley says "Install with collar of needle case facing gear set" but looking at bearing this is not clear what they're on about.
   I'm starting to think the collar being described is best shown in the 3rd picture. Best Regards Rob |

the lip on the bearing cage goes toward the pinion teeth.

Held back fitting the bearing today - forgot to take the pinnion to work with me - twat
But looking at simular postings - the following was found!!!!!! Raised collar pointing away from pinnion:-  Raised collar pointing towards pinnion:-  Its my understanding the second bearing installation is correct but if there's any comments to contradict!!! |

i looked at all my R+Ps and the lip went toward the teeth, but i can't see why it wouldn't work either way. same goes for the rest of the roller bearings.
