Head gasket fitting

[Bob Culver]

I have a similar book Publication 843/C dated 1957 but still labelled Austin Motor Company. I often wondered if it was a reprint of a much earlier but there are some differences so not. For diffs Duckhams NOL EP 140 and Mobilube GX 140. I have never established with absolute certainty if modern commonly available GL5 EP oils are more or less aggressive to copper, or if any past or present are to a degree which matters in a Seven diff. Most oil firms claim not, and presumably the Austin co knew what it was recommending..

For anyone who has not stumbled across factory lube rcommendations previously, note the hub greasing is grossly excessive and invites leaks. The races only need packing on assembly.
