release bearing

Does your 600 have a 4 speed trans or a 5 speed? Single clutch or double clutch? My tractor is a 5 speed with single clutch. The inside of the bell housing looks like this:

Yours will look similar if you have a 5 speed. It will look a little different if it's a 4 speed. In either case you need to disconnect the release bearing return spring(s). On the 5 speed, it's that coil spring around the shaft on the left of the picture. On a 4 speed there are 2 coil springs on either side of the bearing hub.

Then disconnect the clutch pedal linkage on the left side of the tractor so you can rotate the fork shaft forward until the hub can be pulled off the input shaft.

If you have a dual clutch, your input shaft assembly will look different than this, but the procedure for removing the bearing/hub assembly should be about the same.

Good luck!

You can use the trans oil level plug to determine how much to put in. On my 5 speed trans the level plug is that hex head thingy just above the top edge of the running board on the right side of the tractor (see photo below). Pull that plug and pour oil in until it just starts to seep out that hole. Then put the plug back in.

It's probably similar to my Ford 800. I did it with a 1-3/8" socket. I propped the release bearing between two large wood blocks and used the socket to drive the hub out of the bearing inner bore.

Never been inside a Ford, but with most bearings you just drive them out the way they were put in with a hammer and punch.
