Rev counter drive?

Forums

Hello all,

Recently, I bought a set of Model 50 crankcases. Am I right these are from a late alternator model and am I looking at a rev counter drive?

Cheers,

Tim

No, Thats the crankcase breather connection and they aren't alternator cases

Thank you Peter, that's good to know.

Inexperience still showing here... I haven't taken one of these engines apart yet (but that time will be soon) and the thread looked very much like that of a speedo or rev counter drive. I can't remember ever seeing a rev counter on a Model 50, which is why I presumed it would be an alternator model.

Glad that's all cleared up, thanks for that!

 Hello

As far as i know they were no tacho drives on the ES2 or model 50 but i maybe wrong.On my 520 special i had to modify the timing cover to accept a 90degree tacho drive which i bought from the club.This entailed making a suitable platform welded into the casing with screw holes and machining a drive nut to connect to the tacho drive

If you like i could post you a picture of what i did

Regards

Thanks for your answers. I'm not looking to attach a tacho, I was just wondering what it was, because it just looked similar.

Still, for future reference, some photo's are always interesting for those ending up on this thread.

 

Kind regards,
 

Tim
