Does anyone know what the bolt size is for a Cosworth Alternator ?

I need the length but more importantly the dia. I'm talking about the main bolt.

Many thanks..........

 

8mm diameter can measure on for length tonight if you need me to ?

Tabetha.........as alway we can expect an answer from you.

Very much appreciated "again".

If you could have a measure on a length that would be spot-on.

A massive thanks

 

I will do so in the morning, been busy today, but in garage making stuff in morning.

Hi,
My bolt was missing, my dad stole it for his alternator, but I measured the length that it would need to be, 5.5" roughly from end to end.

transit early one with alternator on left or if u have a alternator starter reconditioner near u they probably got one kicking around m8 threaded rod from screwfix would do at a pinch

 

Just go to any nut bolt place and buy some M8 studding and cut to suit, bet I've got some kicking around in me boxes of bolts if you want me to hunt, nss have these on the shelf but have a minimum order carriage charge making just 1 bolt very expensive, give me a shout pm if you get stuck.
