Gary Flinn Posted June 15, 2017 Report Share Posted June 15, 2017 I've done a quick search on the forum regarding this, but can't find any comments. I've got a strange intermittent ticking noise from the Rev Counter when the engine is at low revs, it doesn't do it all the time and is worse when idling. I've changed the Cable for a new one and routed it the best I can so its got no kinks or sharp bends I'm thinking the Tachometer may need a rebuild. The strange thing is, I was taken for a test ride in another TR5 last year and it had the same ticking noise, weird or what. Any idea's? Quote Link to post Share on other sites
stuart Posted June 15, 2017 Report Share Posted June 15, 2017 The ticking can also sometimes be the non return valve on the servo! Stuart. Quote Link to post Share on other sites

Guest ntc Posted June 15, 2017 Report Share Posted June 15, 2017 The ticking can also sometimes be the non return valve on the servo! Stuart. Correct, simple fault could be the rev counter is running dry if so remove and put a smear of butter where the cable attaches to the unit. Quote Link to post Share on other sites
Gary Flinn Posted June 15, 2017 Author Report Share Posted June 15, 2017 (edited) Neil Butter! Wouldn't some sort of Grease be better? Stuart If I it is the Servo valve and I apply the brakes will it stop the ticking? Edited June 15, 2017 by Gary Flinn Quote Link to post Share on other sites
sadman Posted June 15, 2017 Report Share Posted June 15, 2017 I've the same problem with my 4A, original cable broke, replaced with Moss one, ticking started & needle fluctuating between 800 & 1200 revs approx on tickover. It's as tho' something is dry/sticking &, like you not sure what to do. Doug Quote Link to post Share on other sites

Motorsport Mickey Posted June 15, 2017 Report Share Posted June 15, 2017 Broken single strand of wire on the cable "flicking" against something, at higher revs the cable compresses tighter and holds the strand and also of course the higher revs are noisier.
