Wanted nice ND tach for my 550K1
« on: August 07, 2022, 11:27:33 PM »
Looking for nice, original, 100% working tacho (RPM meter) for my 550K1, green colour, brand ND - like one on attached photo (these are my gauges).
My tacho is "hanging", means when I close trottle, it takes quite some time hand lowers down... Also on opposite, when revving up, there is delay till hand react and raises up, so looking for replacement original.

I have just had the same problem with a ND tachometer. Sent it for a service and found,  The damper was the problem and it appears that either fluid it contained was solidified or there was a tiny piece of grit in the damper.
He  flushed it with cleaning fluid and ultrasonically cleaned it a couple of times before refilling.

Erny, I would highly reccomend Peter Horton to refurbish your clock, he's on here and his work is excellent, worth sending him a PM. I know the postage will likely cost but at least you will get your original clock back and can be sure it will be 100%.

Not sure those are the original clocks anyway Erny. I seem to recall the faces were light green and those look to be the blue/green faces off a 550F2 or 550K3.
