req - Manual CCT coach bolt length

[Wicky]

Hi does anyone have a set of Manual APEs or Roah's CCTs that they haven't installed yet as I need to know the length of the coach bolt - ta

you want about 80mm m8. they sell them in b&q

[Wicky]

Are you sure Benny that's sufficient as in this composite pic I made it seems closer to 100mm - 105mm

I used 100mm m10 carriage bolts when i made mine worked a treat

I've noticed on ROAS's and APE's that the bolt seems longer than needed.
It's not going to need more length once it's fitted, unless new chains are fitted later.

ROAS seems to have gone AWOL and I need a set of manual CCTs so after looking at http://www.overstockpartsgalore.com/ $120 where I got mine last year - then I stumbled across http://www.kriegercamchaintensioners.com who makes his own for $70 inc pp (without gaskets) or $80 with

Just ascertaining the correct bolt length based on precedence of APEs etc as he previously has mainly done Kwacka CCTs.

Why not have a word with Bazza, who does converted ones using the standard bodies for £35/pair?
I let him have a few pairs of old ones a week or so back, he was going to get them converted.

He lives not far from you, anyway.

this is an ape tensioner, with locknut set as removed.
the total bolt length is 95mm, but only 30mm protrudes into the engine, up to the chain guide.
this leaves 39mm of bolt sticking out, or 33mm of unused thread between the single locknut and bolt head.

if you used a 80mm bolt you'd still have 13mm of unused thread.

Thanks for that Benny - though in my composite pic the left part of the photo is an APE installed in situ (rear pot) and has 20mm of unused thread - so 95mm bolt length seems to give plenty of margin.
