John Deere Z425 Transmission problems

[Spiky]

Had my drive belt on a JD Z425 fail. . After that struggle bus, I finally got the new one installed, but now the right side transmission is not working, even though the pulley is spinning. Would the transmission have broken when the belt gave up? While Im troubleshooting that problem, the nylon (im guessing) starter gear decided to eat itself. Is there a way to replace that nylon starter gear without buying another starter? Thanks everybody.

Update 5/1: Starters were cheap enough so I just ordered a new one. But the right side drive problem remains. I examined while running and the fan is definitely spinning.. The lever that dis-engages each wheel is set the same as the left side which is working. Could the belt breaking have caused it to fail internally?

There are 3 versions of drives on the z425. 2 have separate wheel hydros and one has a central pump and wheel motors. If you have the one with the goofy angled pulleys double check the release isn't pulled on the hydro. That is the fun one to change the belt on.

Yea, its the goofy one allright. I think it's 10 years old??

The first thing to check on your drive belt is that the belt pattern is correct, then check for good belt tension.

You can replace just the bendix gear on most starters, however, if the starter is old and worn out, it is best to replace the entire starter.

Briggs starter gears are replaceable but they are pain to do. Getting the wire ring off and on is the biggest pain. Brigg use to have tools to do this but they are NLA because they didn't sell enough of them.

The wire ring can get distorted during removal so a new one is needed. Plus they can go flying to Neverland, never to return. I was lucky to get the ring install tool for the Briggs line but removal tool was already NLA at the time.

Now if you never done this either get a shop to it or buy an aftermarket starter.
