During my recent engine-out, I realized that the dash-1 cluch shaft grease zerks could be a classic 'out of sight out of mind' problem.
Once my transaxle was separated, it was obvious the clutch shaft wasn't running free, and warranted more attention than a simple greasing.
Of course removing the shaft requires removal of the clutch fork, which is a pain due to the pins that hold it. Anyway, once removed, I found that both zerks were packed with crud, and the actuation shaft was rusty at both ends where they run in bronze bushings. I also found that the original grease seals (INA G16-22-3) were totally shot and needed replacement. Identical replacements were available on ebay for about $2 ea so at least that was easy.
The zerks ARE almost impossible to see from the top and consequently easy to forget. A little simple maintenance should avoid all rust & crud issues!!
Fwiw the dash-2 doesn't have the same zerks - - the entire -2 clutch actuation system is upsized & 'different'. The dash-2 shaft does has analogous bronze bushings.... not clear offhand how they are lubricated.
For the dash-1 crowd..... good items to hit next time you have a grease gun in hand. Pics show parts after cleaning...note zerk protruding from the bottom area of the case. I failed to take any before pics, probably distracted by how bad it looked
