KAD - Tensioner Rack&Pinion - Cog - Part no?

[alt]

Hi all,
The manual belt tensioners for the KAD (300 in my case) works by way of rack&pinion.

On the back of the stud/bolt that you tighten (to tighten the belt) is a replacable metal cog.

I had to replace one of these before and for the life of me (yes, i've been Googling!) cannot find the part number.

Don't suppose anyone here knows the part number / what i'm talking about? marinepartseurope.com is gone to cat - doesn't have the schematics like it used to.

Thanks all!

KAD42 KAD43 Belt tensioner upgrade kit 877180

It is item 12A in the picture on the above website

Appears to be item 3582168 from what I can make out? Anyone confirm?

OK so turns out it is the right part - ready for collection on Monday (which is great for the West of Ireland) - I'll leave this thread here in the hope it helps others in future.

PS. I've ordered 2, 1 spare to be kept on-board! It snapped when tightening the belt (wasn't over-tightening.... had a torque wrench) - Better to break at start of season when on the hard rather than when the engine is purring at 3000RPM!
