1850 speedometer

super99 · Mar 20, 2014

The speedometer is acting up on my 1850. When you first start driving, it seems to work OK, then the needle starts jumping around and pretty soon, it drops to 0 and stays there. Is this the speedometer itself, or something in the drive? Thanks, Chris

That's the same thing I got when the cable end went bad on my 1655.

Well have you ever lubed the cable?

I had that happen to me one time on an 1850. The keyed drive end twisted off where it is attached to the tach drive. I would take the cable off at the drive end. If you can not loosen the cable end threaded nut(not sure what is called), take the four bolts out that hold the tach drive. Remove and pull the drive and cable out so you can use a pair of vise grips and separate the drive from the cable.
Also, have had the tach drive strip its gears if the tractor has a lot of hours on it. They are around used, but kind of expensive.
Had quite a few 4 digit tractor over the years, and have never lubed them.

Can you unhook it down under the tractor and put an electric drill on it to spin it? That would eliminate the drive if it still didn't work. Work your way up from there.

It don't sound like this is the problem but check that little nylon gear down on the drive end as well. Have changed several of them.
