Gearbox cover.

[Drahchir]

So the spring(gu04238300) failed.

I managed to get home!

 I have read all the posts and understand the reason why it fails.

I’ve got the new spring. Actually bought 2, so can go ahead and replace it.

Forgive my lack of knowledge, when I removed the gearbox cover it was metal to metal. It came off really easy and has never leaked! No gasket and no gasket sealer.

I read that LOCTITE 518 sealer has been used and therefore creates a seal. Also filing down the shaft to 15mm sorts the issue. So do I put it back on metal to metal or use a sealer which would make it more difficult to remove the next time?

Why is there not a gasket?

Also where the gear shift lever spline goes through the gear box cover does that have to be removed to get to the surclip underneath? 
I’ve bought a new seal for where it passes through the gearbox cover!

 

 Hope that makes sense to anyone reading this!

I’m doing it myself so I can learn more about my V11 Le Mans rather than taking it to a dealer. I’ve downloaded the photos which have been previously posted, so am doing my homework.

If this is just rambling please ignore! If it makes sense to anyone reading this post then any advice would be appreciated!!

I’m only a humble stonemason!! Not a mechanic. And finally,, I want to bleed the clutch. Again I have read and seen the pictures posted, is it really that difficult to access? If anyone has a picture/pictures of the precise location that would help me greatly!

My kindest regards 

Drachir.

The Loctite 518 will be a good choice . make suer the mating surfaces are perfectly clean with Brake-Kleen or similar product when you reassemble.

Thanks.I still can’t get my head around ,why know gasket? 
That’s what is bothering me! As I said to remove the cover next time using a gasket sealer would be more of a ball ache! Thus creating a bond. I know it’s not a strong bond but still.

 Understand the principles of the reasoning for using a gasket sealer filling up any slight discrepancy’s. So why use a gasket on the rocker covers,sump or anything else. When the gearbox cover has know requirement for a gasket? Which of what I’ve read Guzzi doesn’t fit from factory?

I am just being inquisitive. Apparently knowledge is power!!!! Alas not according to my customers who always seem to know so much more than me 🤣🤬🤬🤬

Because it's modern engineering. Very few engines these days use gaskets because sealants do a better job. Metal to metal with sealants means no gasket compression over time, no gasket failures and less parts to assemble and manufacturers save money. The Guzzi engine is a transition engine between gasket and no gasket engines. Ducati twins haven't used crankcase half gaskets for over 30 years. Removing the gearbox cover is no problem as there is a built in leverage point to pry it off. 

It's an engineering evolution. BTW the original Guzzi BB rocker cover gasket is a PITA and fails regularly. Use a later metal core gasket. Same for the front cover gasket.
