type 9 problems (also posted on Sylva list)

[norma]

Had a bit of a rattle coming from my clutch release fork / bearing so split the box from the engine to take a look.
There is about 5mm of play at the end of the gearbox input shaft! Is that right?

(Click the pic to get video)
I realise that the shaft will be kept central whilst hooked up thanks to the needle roller bearing in the end of the crank BUT seems too wobbly to me!
the oil seal is also leaking (and its not old) and I suppose it would if the input shaft was able to wobble about!
Any thoughts?
Thanks

Norma , ALL INPUT SHAFTS will have that amount of play at the nose which is why such great care needs to be taken when lifting the box so's not to move the seal(ie. not holding the nose end) However if the seal is leaking then bearing and seal plus gasket is suspect . My box is virtually new but still leaks a little on short pointy courses when flat in the first three gears a lot ie. 8,000rpm every gear etc

Thanks Rob - I looked at the exploded diagram of a type 9 and it looked like the input shaft only had the one bearing - therefore play would be normal - but that play would be removed once the nose was tucked up in the crank bearing.
I'm getting a hell of a rattle from the clutch release arm and upon inspection I can find nothing wrong with the bearing, arm or pivot point on the bell housing.
Still, with my bell housing mods it should only be a half hour job to get the box sepearated in future if it still rattles after re-installation.
Oh - is there supposed to be a spring washer type thing on the pivot point of the bell housing? I have a flat washer but am wondering whether it should be curved to take up slack in the pivot point???
Never had an issue with this box on the old engine, but now I'm running a lightened flywheel / uprated clutch setup, I'm wondering if thats FUBAR'd the spring! (Its a BGH box btw)
Thanks

So long since I had the mechanical arm in mine that I can't remember whether any washer was curved or not . I merely cleaned the pivot and put copper grease on it

is there a little plastic sleeve on the pin that locates the release arm? I had the g'box out twice chasing a rattlefrom the front of the box. Even had BGH double check it. I just couldn't get to the bottom of it. It went away after a bit, still does it every now and then. I guessed that there is less inertia with the lightened flywheel and therefore more chance of backlash at the input shaft????

i like your thinking mike.
no, there's no plastic sleeve and I'm pretty sure that's where the rattle is coming from.
Didn't know there was supposed to be a plastic sleeve - oh well, best do some googleing!
I think the pin maybe a little to long and I might try knocking it back into the bell housing wall a little - it seems to be an intereference fit so its possible is moved a little over the years.
I like your flywheel theory too, I had a 1.8 flywheel on before, so yes, the dunnell one is much lighter.
Thanks!

Took my gearbox out last night. There is a "rubber" sleeve on the pin for the lever. It is very soft, (dont know if it is actually rubber) I think a small bit of cut tube will do the job.

Thats good to know - I have some 8mm air pipe that is spot on for the job, the lever has an 8mm cut out ans the pin is 6mm so 8mm (od) air flexi pipe is spot on.
Have got new oil seal too, they're about £2.50 each, you don't need to go to ford for them, they're a standard part.
