3415s with cracked axle tube.new tube or swap rear

Recommended Posts


If i can't fix my cracked axle tube, I'll be looking for a little newer tractor that can still use all of my attachments.

What newer/better model should i look for?

I have:


belly blade



mighty mac shredder

leaf vac

axle tubes are available. I may be easier to find another rear if your not mechanically inclined. Newer model would be a 7000 and 7100 series. As far a hydro swap its not a bad job you just have make sure you have all the parts required. A donor tractor is best.

Here is a link to ebay listing that has the large frame service manual that I talked to you about.


This link will get you the seals that you will need.


This link will get you the brakedown of the shuttle rear end on Small Engine Part Warehouse. The gasket for the rear end is still available.

Sounds like you are going in the gear case...Another few items you should order are all of the woodruff keys. I think there are around 9 or 10. They all seem to have wear on the sides and start rocking around in the broach/slot. You especially want to get new ones for your new axle tube..

Agree with all the above, but, I would add to go ahead and disassemble the gear case(transmission). If there is a bearing, replace it. Same with seals. The axle tubes have bearings or bushings, replace. You have a choice, do a large job and do it right, or do a large job, several times, until you finally get it right.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁

      It's in pretty sad shape, but yes I have a yellow plastic cap that I'm fairly certain is what you need. PM me your details and I'll get it out to you.
