mark_smugglers Posted April 28, 2021 Report Share Posted April 28, 2021 With my TR6 finally on the road (thanks again to all on here for the huge help over he last five years) I’m sorting through minor issues. I have noticed the Rev counter ticking and now making more of a grating/ whirring noise. If I take it out, where should I be aiming any oil and what sort of oil also? WD 40? Silicon ? Etc.

RobH Posted April 28, 2021 Report Share Posted April 28, 2021 If you are lucky the noise will just be a dry drive-cable Mark, best lubricated by withdrawing the inner and rubbing it with graphite powder. If it really is the rev counter itself it isn't just a case of squirting oil anywhere. It may be the bearing on the rotating magnet assembly but you need to open the case to get at it. This link is labelled speedometer but the rev counter is very similar: http://obswww.unige.ch/~wildif/cars/docs/Smith-jaeger_speedo_repair.pdf Quote Link to post Share on other sites
Mike C Posted April 28, 2021 Report Share Posted April 28, 2021 (edited) Be very careful. I dismantled and lubricated mine with silicon lubricant and I might have have overdone it- it started reading maybe 25% high after a month or so. I wouldn't just spray lubricant into the case. Is your tacho cable OK and properly lubricated? You also need to keep the cable lubricant maybe 200mm from the tacho connection at the back of the meter to stop oil migrating into the instrument.

harlequin Posted April 28, 2021 Report Share Posted April 28, 2021 My rev counter is noisy if I don't get the run of the cable just right, try getting the cable as straight as you can with long bends George Quote Link to post Share on other sites
BRINDUS44 Posted April 28, 2021 Report Share Posted April 28, 2021 Hi Mark, I had what I thought was a noisy rev counter. Turned out to be the original servo vacuum non return valve rattling, and the noise transfer through the dash. Worth a check. Ian Quote Link to post Share on other sites
