trailhopper 50 #1 Posted January 18, 2019 So I recently picked up a 1991 520H and was looking forward to having full instrumentation, but the tachometer was non-functioning. After some troubleshooting (using this site), it appears as the actual tachometer is burnt up. After this discovery, I searched for a replacement and found this place selling new Toro tachometers (part #78-006) for a reasonable price. I haven't hooked mine up yet, but did receive it and looks perfect, Not my site, not my product. Just thought that I would share. https://www.marine-surplus.com/product/teleflex-marine-toro-0-4000-rpm-tachometer-gauge-78-0060/ -Scott 4 1 3 Share this post Link to post Share on other sites

oliver2-44 10,444 #6 Posted January 19, 2019 Forget me if I'm stealing this thread, but I've wanted a tach for my c-160. Can any of the 520 guru's tell me how that toro Tach gets it signal and could it be retrofit to a K341? 1 Share this post Link to post Share on other sites

I'm not a guru by any means but I believe it gets its signal from the voltage regulator because when the VR is bad the tach does not work also on the Onan the coil fires both cylinders simutaniously, maybe Kyle @fast88pu or @cleat could cast some light on the subject. 1 Share this post Link to post Share on other sites
cleat 7,123 #8 Posted January 19, 2019 Tach gets it's signal from the AC from the charge coil. I had a Wheel Horse tach in my Ford LGT165 with a Kohler K341 and it worked perfectly. Cleat 2 1 Share this post Link to post Share on other sites

That's why I waited until I had them in hand to post. Now I just need the time to get one installed. Share this post Link to post Share on other sites

Yes the 520 does from the regulator. If it was a magnum single you can get it from the kill wire buy on an old K series I'm not sure. I would ask in the pulling section. I run a tach on my predator and tiny tachs on the rest. Share this post Link to post Share on other sites
cleat 7,123 #12 Posted January 19, 2019 Just connect to one of the AC lines coming from the charge coil to the regulator. If one does not work, try the other one. Mine worked perfectly but there may be charge coils with different number of windings that could cause tach to read differently. Cleat Share this post Link to post Share on other sites
bds1984 1,479 #13 Posted February 1, 2019 I have a tachometer on my C165 that is connected to one of the AC terminals on the regulator and it works fine. I believe the issue is the flywheel has to have six magnets on it for the tachometer to read correctly. I am going to buy a tachometer and install it on my 315-8. Thanks for the link!

hihousej 0 #15 Posted July 15, 2020 I bought the gauge from Marine-Surplus and it works perfectly in my 520H. Had to run a small drum sander in the dash hole for a half a minute to wallow it out a tad. Wiring was there and it went slick and looks great. This one hasn't had a tach since the turn of the century. Share this post Link to post Share on other sites
