M602 Tachometer

mineer701 · Feb 23, 2020

I installed a new tachometer cable and tachometer on my M602. The tach seems to register the rpms too high. Is there some gear in the tach drive that could be incorrect?

If you bought a tach made in China or India I've heard they register too fast. Not much you can do about it. Do you have a 90 degree box in the tach cable or is it direct to the tach (in-line)?

The tach cable is straight (in line) to the tach from the distributor.
My old tach seemed to read too high also. It showed about 2500 hours. I replaced it because it was making noise and jumping around. I don't know if the old tach came from India or China but I am sure that the new one did as it was way too cheap to buy.

I believe gas/lp and diesel tachs different.

I have a 602 diesel and installed a India made tach, it works fine. The drives at the engine are different on the gas and diesel. The tachs are the
same. Make sure the drive gearbox is clean and greased.
