420 Tach connection

jsborn · Sep 24, 2014

If I wanted to add a tach/hour/speed meter to my 420 where would the cable connection be made is a different distributor needed?

Also are there any after market manufactures for tachs for the 420 4 speeds?

Thanks for your help

My 420W has a plug in the base of the dist. where the tach cable is inserted. I would guess that transmission would have nothing to do with it.

The transmission only has to do with the tach face and ground speed calibration on the face.

The main thing I am interested in is will I need to find a Dist. with a tach input or is there an other way to do it?? My existing Dist. doesnt have a place to screw a tach cable in that I can see.

Looking in the parts book it only shows one Dist. but you say yours attaches to the dist.

I am confused. (what else is new)

js, I went through that with my 420. I am going on memory since I have sold the tractor and the manuals went with it.

Apparently some came without a tack or it was an accessory. Either on or close to the distributor there should be a large plug like you see on trans oil drains. That plug comes out and a tack drive assy screws into that hole. I got a used one from John Shepard and it worked fine. The cable then goes from that drive assy to the tach.

It has been a long time, I can't imagine that not being in the parts book.

good luck.
