Murray 40702x92a with a 5 speed transaxle.  One of the axles flops up and down.  Wondering if this can be fixed by replacing the outer bearing that supports the axle or if it is something on the other end of the axle.

 

Thinking maybe someone has had some experiencing with this.

How much is it moving up and down? There isn't much to those transaxles. Have you checked to see if the mounting bolts are loose? Some pics would help me and others to see what you are talking about. If the Murry was made by MTD, there are some great MTD Manuals in our Manuals Section. Good Luck, Rick

My experience is that once the bushing (not bearing) gets worn, the axel gets into the aluminum housing pretty quickly.

Usually happens with tractors that have weight added to the rear, but could happen to any eventually.

Here is one of the worst ones I've seen

Made a short video. Should have used a tripod... sorry but it makes the point.

Need to get the specific number for this transaxle.  

 

Seems some used ball bearings like this one which goes for $30 retail

Genuine Tecumseh Peerless Sealed Ball Bearing # 780119

I don't want to ruin the transaxle so I going to take this tractor out of service till I get around to replacing the bushing.    

 

Thanks.

Transaxle is 920-012 Peerless

 

Can anyone tell me where in this parts breakdown is the axle bushing we talked about in the previous posts? The axle seal #23 but I don't see an axle bushing.

 

Link to sears page which lists the parts numbers keyed to the diagram.

EDIT: According to http://www.g-team.us...er/peerless.pdf the "The 920 series transaxle is very similar to the 900 series." and "The 900 series is like the 800 series transaxle." and it shows that the 800 uses ball bearings. Oh boy :)  I wonder why they are not shown it the diagram.

Those are on the gear sets though Kenny, not actually on the axles.

 

If I remember correctly when I pulled my 6 spd apart, there were no outer bushings or bearings, the housing acted as the bushing, but I maybe wrong, it's been a few years.

I think I can shed some light on this topic.
Ten years ago I helped a friend with his mower that showed symptoms of slipping somewhere.Eventually it locked the right wheel while the left was spinning!.
Something had to be done.Up in the air with the rear end and yes,the right wheel was stuck.The left could esily be spun,so something was seizing the right axle.
Not feeling like tearing down the complete transaxle,we loosened all four(if I remember correctly)screws a little and very carefully we could pry it open just enough to look inside.And to our surprise-no bearings or bushings at all!
The axles just run against the aluminum housing.Presumably greased,but now completely dry.
A Quick fix was needed so we simply oiled with a thick gear oil.
It still runs today as far as I know.
Take a look at this video(about 5 mins in)and you'll see the "bearings" and far out the thin oil seals.
