firstly I'd like to buy this book "A practical guide to the restoration of the "J" type (1932-34)" by G. Howell see attached image failing that there is a drawing of a clutch alignment tool on page 40 in the section "Engine and gearbox" any chance if someone has this book that they could possible take a picture of the said tool and either send it to me or post it up here please......

Not p40 !

Indeed I can't find any drawing of such a tool in my copy. My cover colour is orange (2009 edition) so there may be more than one version.

Any other suggestion?

I use a spare first motion (input) shaft to do the job.

All you need is a stepped shaft that is a good fit through the clutch driven plate splines and slots into the spigot bearing to hold the driven plate centrally as the clutch cover is tightened up against the springs.

thanks Chaps....blast only 40 pages out LOL......so you can't actually use the tool to align the splines on the pressure plate.....not that it matters too much it'll just make sliding the first motion splined shaft into the clutch and spigot bearing that little bit more difficult.....not a whole hill of beans to be fair

That is exactly what it does, keeps the driven plate centrally on assembly.

If the driven plate is not well centralised it can make getting the first motion shaft through and to the spigot bearing very difficult, if not impossible.

P.S. one might categorise the "full diamond knurl" together with "bells and whistles."

Firstly, there are at least a couple of versions og Graham's book, which may well have different covers. I have copies of the riginal version(s) which comes in three parts. A later version puts all three in one copy. BTW what happened to Graham? I have not heard from him for a long time. He helped me a lot when I first got my J2. Secondly, there is no need to have a bespoke clutch alignment tool (though I'm sure it helps). I have often made up a rough and ready version from a short length of 15mm copper pipe wrwpped in duct tape to fit the two diameters (spigot bearing and clutch splines). I have used this method on a variety of engines (including my J2) to good effect.
