a mundane question: what's the length & thread pitch (SAE or metric?)of the clutch slave cylinder bolts? I need to restore threaded holes in bell housing; p.o. buggered them badly, not sure the ones I removed were correct. thanks-Jerry

From spec sheet think it is metric 8 mm - length would I expect be the length of the securing flange of the slave cylinder + width of Gearbox flange minus a few mm's.

You can download a Works Manual from www.triumph-cars.co.uk under section PDF's

Cheers for that Neil,

I found that a really interesting web site, even nabbed me a copy of the manuals as well [:)].

Hi Jerry,

What I did was to drill and tap the holes 10mm and also drilled out the holes in the clutch slave cylinder to match.
I found the thread was too poor to retap the hole the original size.
And didn't want to take the chance of it failing miles away from home!

Cheers. Dave

Anyone have a clutch housing on the bench/shelf to take that measure from?
To this should be added:
the thickness of that sheet metal ("rear adaptor plate") fitted to the engine block and
the thickness of the washer(s) used.

Then you can decide on a suitable length screw for this application...
And as always I recommend stainless part threaded screws (with an aluminium based
antiseize paste) so you can easily take it apart twenty plus years from now... [:)]

Hi,

I always drill the blind hole deeper and tap the tread down as far as poss and longer bolts.

Cheers John

Hi Beans,
That would probably be a better option, I always thought it would have to be done at a machine shop, I didn't realise there was a DIY version. Might be worth looking out for a set.

Cheers, Dave

many thanks, guys, especially Neil for spec sheet posting. as there shall be no more threaded bare aluminum holes anywhere on either the head or bell-housing, I want to get it right the first time. as is well known, threading anything into bare aluminum is a crap-shoot, eventually you'll have problems. found that out years ago on my old Harley shovelhead.there's now a threaded insert seized onto the front spark plug, & studs where bolts used to go! gonna drop the sub-frame today, blast & POR-15 it, & photo-document the engine bay prior to stripping it for repaint...Jerry

Jerry, what part of US you in?

I keep telling you guy to buy two bolts about 1/2" longer to start the slave cylinder with, then remove one and replace it with the original, then do the other.

No more stripped out holes.

Does anyone listen?

I do but when I overhauled my slave cylinder I didn't have any problem putting it back on. When I do my clutch this winter I may and will be paying attention to it.
