How do you lubricate the hub bit of the above hub..
There doesn’t seem to be any port of any kind visible.

Sheldon's web site, as usual, is helpful.

I used to have a SRAM dualdrive 3x8 and it was easy enough to strip. From memory just a couple of cone nuts on the left hand side and it just came out.

I only did it a couple.of times though, and based.ok advice form somewhere used to pour some light oil down the middle of the axle

The SRAM service manual should still be online for all the hubs.
Spares for these hubs are possibly now hard to get hold off since SRAM stopped making IGHs nearly a decade ago. Somewhere like SJS would be your best bet for a UK source.
Brucey did a really excellent post about these hubs many years ago viewtopic.php?t=92333 and would be worth reading..

I've extracted the internals then without stripping them down oiled them using fingers dipped in car engine oil whilst rotating all the moving bits.

Repeat every couple of years

Works for me :D

Thanks to all. I’ll give oiling a try first and see if it needs anything else.
