Hi Adam,
Using the last parts exploded view view, part number 6 certainly looks like an oil seal, and described as such. I fits into the casting and alows the gear selection shaft to partly rotate, and go in and out, yes ?
If I am correct, there is a consatiened bellows gaiter as well ??
Gasket for casting to gearbox, and spring dowels ?
The spring dowels, removed to allow the gear selector shaft removal and easy seal change ?
IF your gunna remove a/the spring dowels, get some new ones....
The splines on the gearbox input shaft/first motion shaft need to be clean, rust free and lightly lubed, for when the gearbox is refitted.
Remember I mentioned some suitably long threaded studding to make at least two convenient and removable gearbox aligning studs, to make life easy for your self.
The gearbox input shaft/first motion shaft, the splined shaft, it's oil seal and bearing......?
It's been remarked that that bearing and seal may be problematic due to heat and low oil level etc...
How is it. How does the shaft turn, stiff, notchy, gritty, Crunchy or anything other than very smooth, quiet with no play ????
The fingers on the pressure plate looked fubar, as the clutch release bearing is.
You also renewing the fork bearing shuff.....
So in effect, more or less, a complete new clutch along with clutch release mech, and other stuff as necessary ?
I love that phlem green !
Remember black dust in bell housing will contain asbestos more as like, and should be cleaned out .
Clutch debris/dust may/will contain metallics as well which can influence any electrical sensors housed in the bell housing and best the flywheel. I do not think your bellhousing has any sensors, but remember for future reference.
People reading this will also take note.
Finally, the clutch hydraulics.....at least a change of fluid...
