Does anyone know where the tach cable goes? The cable isn’t there and I can’t find where it might go. I’ve read pretty much everything here but still can’t find it.
I see a small hole into the bell housing near the floor and under the throttle. On the right hand side if you’re sitting in the seat.
If you have a 350b.. a picture would be amazing. Thanks
350b tach cable location?
Re: 350b tach cable location?
Not sure if it is left or right hand side, but you are in the general location.

Re: 350b tach cable location?
On all 350s the location is the top right hand corner of the bell housing or engine plate. So while sitting in the seat it will be just to the left of the brake pedal.
On a 350B ... depending on serial number, the cable will either go in horizontally on early units or vertically on later units. Most of them will have the gear in place even if the machine came without a tach. They will have a plug or a cap covering the whole. Sorry I don't have any pictures but it is pretty simple to see it.

Re: 350b tach cable location?
That’s great. Exactly where I thought it was. There’s a threaded hole that looks to be 3/8 npt but not verified. I can’t see anything in there and there isn’t a plug or a cap.. most likely plugged with debris.
I assume the cable just threads in, meshes with the gear inside of that and job done? I need to locate a cable but shouldn’t be impossible.

Re: 350b tach cable location?
I don't think those threads are NPT and if they are they will be straight pipe and not tapered. Your cable will need to be the one with a probe with a flat rubber seal that fits over the end of it. Then yes, it does slip into a mating hole with a slot that the probe fits into. Those holes are hard to see inside of but if you can get to it, you should see what appears to be a small hole with a slot on one side.
Most of those Tachs were mounted on the floor board and the cable was actually pretty short. Not sure they have one that will reach all the way up to the dash. Those dash mounted tachs had a cable that goes into a vertical fitting on the top of the motor plate. So you will just have to see what's available.
