JD 420 wheels on a JD 318

Another question. Is the front spindle size the same? In other words will a 400,420 or430 front rim fit on my 318? Here are some pics

Yes they will fit and no they won't fit. Here is the things you need to look for. What year is your 318? Or basically-does it have metric or SAE spindles? Newer is metric. I know my first year 1987 332 is metric but I don't know what year they started metric. The 420/430 fall into the same limbo as the 318 with having two hubs.

Next-you will need to put stops on from what I have heard so it doesn't hit your frame or cylinder when turning all the way. But if you work those issues out then you are good to go.

My question-how do you have the cab with loader controls? More pictures of that please?

Coalminer, hey, sorry for being so late replying. I got the wheels on and even went with a slightly larger wheel. 18.5x8.5-8 and a 6 ply. Here are some picks showing the cab. I had to do a little cutting on the brake side to fit around the loader frame and had to run one hydro line through a hole.
