How many miles has it done since it was built and what condition were the bearings in when you took it apart?

 

[red reading]

What clutch do you have? And how old is the box?

 

[Thor]

The bearings looks great and have no play! I use an Sachs sinter twin plate clutch. The box has arround 5000 km done by me and before another user from uk but he told me that has 2000 miles done. But If is real so i don´t know....

Does the clutch have a sprung or solid centre?

 

[Thor]

No, the clutch was ok but that was down the limit of thickness...

 

[red reading]

So is it sprung or solid?

 

[Thor]

Solid! But the noise was louder from time to time....

What oil was in the gearbox too, sounds like you had the rattle from the solid centre clutch on a large tooth gear set, I have heard mine and others do it as well, quaife seem to do it more than others for some reason.

Are you using a standard final drive in the gearbox? If so check 2nd gear on the shaft as they have been known pic up and rattle and whine.

 

[Thor]

I have the Silkolene PRO SRG 75 in it.

Here you can here it:

Good question but i don´t can tell you if it is the standard final drive. I had mean that was complete quaife?

 

[red reading]

Quaife do not make final drives, and all I can hear in that video it a tappety cylinder head.

 

[Thor]

The tick was the valves / guides and the rattle is the gearbox! believe me ;-)

Ok than i have the Std final drive in it...

 

[red reading]

Strip and check the box then.

 

[Thor]

We have strip the box but all looks good and the bearings has no play.

 

[red reading]

Now take the gears off the shafts and look

 

[Thor]

Ok we will do.
