Subject: Re: Smiths rev counter drive off of Rotax AT146 dynamo?
Thanks Mark! I actually have been in touch with them, and they don't have anything "off the shelf" for the application. So, I think we need to put something together (?!). The other possibility mentioned by Jo Moss Kitcher was getting the rev count "...from the back of the crankcase on the right hand side - in which case it takes its drive from the oil pump drive (so in other words, the gear on the camshaft that drives the oil pump also has a shaft going upwards - which mates with a slot to drive the rev counter) Have a look and see if there is a 'blank' plug screwed into the top face right at the rear of the crankcase close to the edge of the cylinder block, or whether there is a brass screw thread attached to the blank - if there is, then the drive is already there."
Does anyone out there have a rev counter set up this way, and would be willing to share photos? Thanks --
