Gear selector mechanism

[Jugs_S]

I've been considering the reason for the engine oil in the gear selector mechanism. It would seem that the gear could be just as easily lubricated with a spot of grease and the same for the selector shaft.

I'm thinking about threading and blanking of the 2 oil pasage holes from the crankcase proper to make this a separate void (yes some thing with the same expantion rate). This would mean you could open the selector cover to adjust, if required with out having to drain the oil or have to bike on it side.

Thought anyone.

You will also need to seal the shaft, oil will definitely seep through there.

Seriously, don't think it's worth the time and effort.  Haven't needed to open it on my GTL for the last 5 years, and that was only to renew the drive sprocket!

Or you could just carry around two test tube bungs when you need to pull this cover off.

I'm with Piet on this one, can see the point. When leaning the bike over it's only a few degrees, not like laying it on it's side!
Only times I ever remove it is to change sprockets, and last one lasted over 30000 km thanks to the Scott Oiler.

As you see the cases are empty so its no real work at the moment. The small amount of oil loss through the shaft could go to lubrication. Its putting the chain on the sprocket that gets up my nose. Yes last time I put an engine in the frame I did not put my 6" of chain round the sprocket.

Jugs, I use to remove my chain regularly for cleaning and never found it difficult to feed it back onto the sprocket and out the bottom again. Put a screw driver through the inspection hole and turn the sprocket. O-ring chains are stiff enough to feed in enough for the sprocket to catch on the chain and the shape of the casing will roll it out the bottom, piece of piss :

If you folks think a Laverda is tricky to get the chain over the primary sprocket, well, you ain't seen nothing yet! As Rob says, the castings and the tight fit of the sprocket just feed the chain nicely over the sprocket and out the other side. The only problem you could encounter would be reinstalling a worn (but not worn out) chain; it might be floppy enough that getting it onto the top of the sprocket could be a bit of a challenge.
I think I'm just one of many here who've fed chains into total black holes at the back of the gearbox while turning the engine. But it's really rather simple to get chains on almost all bikes. Some just require a bit more patience than others.
