GC2310 Tachometer Installation

Hello to all --

I've noticed some discussion on the forum here about the older model GC's not having a tachometer. That issue is probably the only one I have with my machine (2004 model) -- I really do like it a lot! But it seems silly for the operating manual to specify a certain RPM, and then have no way to determine whether you're at that RPM or not.

I asked my local dealer about adding one using MF components (I like the idea of using stock parts). The cost would be around $300. Bad enough to be sure, but what really made me decide against it was knowing I'd have to remove one of the engine covers and replace it with an updated version that would accomodate the tach drive.

The dealer recommended I check out a local auto electric parts supplier in the area. This I did, and was able to come up with a tachometer installation that I think is just as good as the new factory version -- all without having to open up the engine. Cost was just over $200, and resulted in a very smart looking dash (if I do say so myself).

The job wasn't all that bad. If anyone would be interested in details, let me know, and I'll post more pictures.

Yes, I would be interested in knowing whose kit it is and where I can get one.

I used a tachometer from ISSPRO -- their R8501 indicator, with R8906 sensor kit. I'd recommend this system to anyone considering the addition of a tachometer, because it uses a pair of small magnets to sense the rotational speed. You won't have to do any calibration (as you would if you were to tap the alternator). Just mount the magnets on the engine flywheel and you'll be able to measure RPM directly.

I don't know how widely available the kits are. I was able to purchase mine at a local supplier (Vineland, New Jersey) that deals quite a bit with tractors, as well as cars. I'm sure an internet search will be able to locate some ISSPRO dealers.

Hope this all helps!
