The rebirth of Lazarus
mickwinf:
i think its actually the lh one i need as had the crankcases upside down, i think it is the one at neutral switch end but will check again
Oddjob:
The left and right look almost identical, the way to spot the difference is that they both have an inward curve on the fork, the outward curve is the difference, on the left it's a nice arch shape, on the right it has a section that dips in right on the crown of the arch.
We are talking about the metal bracket coming off the tube that holds the fork ends BTW.
All my left hand ones are really good.
I contacted the Italian people today asking for a price for all 3 selectors, they are 450 euros for all 3 but they offered me all 3 for 375 a few years ago. I'm seeing if they'll still do the same deal. If they do I'll sell my NOS forks, the middle fork is the rarest and can fetch close to £200 alone, the left hand one is around £100-120. So if I sell those it almost covers the cost of the new ones.
2/3rd gears are soaking in brake cleaner, we'll see what they look like shortly.
I've often wondered why the needle rollers are different on the 2 shafts, one has them captive in a cage and the other has loose rollers yet both are the same size.
mickwinf:
what you say about the two needle rollers is interesting, both of mine have caged rollers, however one has one roller per gap in the cage and the other has two rollers per gap.

"I've often wondered why the needle rollers are different on the 2 shafts, one has them captive in a cage and the other has loose rollers yet both are the same size."
More load and lower speed favours crowded (rollers next to each other) and higher shaft speed ordinarily heads toward single rollers spaced individually in their cage.
Logic would say the clutch shaft has crowded, with the remote shaft using singular rollers. I don't know which orientation they are in this engine.
Oddjob:
Looks to be the other way round. I took one apart the other day, the cage was rusted into the bearing housing and it had the pushrod hole so it must be the clutch one. As said this was the caged one.
Normally there is one roller bearing where the rollers just fall out when you remove the bearing from the shaft and the other which doesn't. Normally have to use grease on the loose roller type to keep them in.
