 Off topic, but one more illustration while I'm on a roll. This one shows a modification to the rear journal in the Main Bearing Panel (MPB). Both are hand cut with a file. The notch allows a little oil to flow through the joint between the upper & lower bearing shells, and to then flow back to the rear Thrust Washer. It's the rear one that takes all the axial load when you step on the clurch pedal, and this mod gives it a more reliable lubrication.

Don't get paranoid, this is a recommended modification, not a mandate. There are a lot of old 907s out there that don't have this mod, and I don't believe it can be done on a Mk I 907.

Regards,
Tim Engel
