Also I managed to strip down and rebuild the ergopowers
They looked a little ratty outside but the insides were actually very clean with what looked to be original grease possibly. Nonetheless I soaked it all in white spirits and degreased it.
I also ordered new G-Springs and spring carriers which are fixed stationary into the body
The ratchet ring then fits inside this and the springs sit into the notches of this index ring. The index ring is spun around on a shaft which connects to both shift levers. It pulls along the cable on one side as well. This gives the indexing to the shifting. Quite neat actually, this is the first time I’ve pulled one apart. Although I know the springs need regular replacing.
The right hand spring carriers are not available anymore so you have to buy the later model one and modify it. Newer model one on right here
It involves cutting off that stub and filing it down so it's flush. Pictured on left here
Then because the little stubs that extend into the shifter body are shorter I had to create little spacers from some aluminium foil to get it to stay put and stick this into the cutouts in the shifter body. You can see this next to the bearing
All done, with a new set of hoods. The funny thing is compared to the later 11 speed shifters, these have a much more definite solid click. The weakness of these old ones is apparently the springs and carriers regular replacing. Amazing thing is though that these shifters are nearly 30 years old but I still can get individual replacement parts for them...
