    Posted: 23 Nov 2021 at 8:03pm
I was able to retrieve the original cork float that was loose in the tank (so that's why my fuel gauge doesn't work, hmmm). Been shopping online for a replacement float and looking for info on how to attach the new float. Seems people get pretty creative with substituting floats from used auto pumps. But if I order a new float specifically for the D12, does it come with whatever I need to attach it? I see there are indents in the rod, above and below where the cork was originally attached. But no remnants of whatever the original hardware was that fit in those indents. How to attach the new float?

Next, the rubber gasket for the gauge is hard and cracked. I read where people had trouble getting a replacement that would actually seal well. Can anybody point me in the direction of where to order a gasket that works?

I used a non sinkable float from a car, kind of flatted oval shape. It is slide onto shaft up against a washer and flat spot, then a washer behind, rod flattened behind washer to hold it on. Gasket is available thru AGCO and several other sources. HTH Tracy

here's a thread on gauge floats;

https://www.allischalmers.com/forum/d17-gas-gauge-float_topic116387.html

OR, a Model A float ; Ford #A-9313-C works very well.



It's what I used on my D17sIV

A bit of modifying is in order, but it can be done with ordinary tools and a drill.
IIRC, the open end is swedged to retain the float.  Just have to use a small hammer and "re-round" it, then file it down smooth 'til you can remove the float.
Drill a small hole for a brass cotter key in the same area to keep the new float on;
used 2) brass washers , one on either side of the new float.





If you don't like buying Chinese, buy from Norm as in the thread above.

For a gasket, I'd get some stock gasket material from an auto supply and cut one to fit.
Apply a thin coat of Permatex #2 to both sides of the gasket. Trim if needed.
Permatex #2 is the non-hardening type.

I had the same issue on my D17 this summer. The movable gauge parts were pretty wore, so I bought new. The new gauge doesn't read correctly. 1/8-1/4 on the gauge is empty. I ran out of gas a couple weeks ago...

I've just used a sediment bowl gasket for the gauge. There are a couple different sizes and I don't remember which one fit, although it is just a standard size, nothing special. 
If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

sometimes you have to bend the wire arm just a little bit to make a guage read correctly when you replace parts, good luck, usually takes a couple of tries!

Great pictures! I have small copper washers and steel Cotter pins on hand. But I'll try to find brass if that's going to hold up better.

As I mentioned, my float had already fallen off the rod and there are no washers left, must have disentegrated over the years. I will take a closer look at the rod. Seems like it just had flat spots, indentations, not flared out beyond the round shape (if that makes sense). Maybe the flare is so minimal that it's not obvious.
