L-225 Clanging noise in transmission

[SoftwareGeek]

Hey,

I've got an L-225 which has done me great for years, and I depend on it! Recently, I've starting hearing a clanging/ratcheting sound in the transmission when a load is on the rear wheels - such as going up a hill. It sounds like the noice an impact wrench makes when it has tightened a lug nut all the way.

While this noise is going on, the tractor doesn't move. I find if I put it into reverse I can make headway, but the forward gears don't seem to be working at all.

I figured that I'm at least in this for a clutch job, so I've gone ahead and split the tractor & pulled off the clutch. I split the tranny off today; and everythingn LOOK's ok. Any suggestions for how to continue troubleshooting? I'm going to be laid up in a month or so while I go through Chemo, and I need to get this running for the hired help.

Cheers

I don't have a clue what your problem might be, but I'm glad to see another L 225 owner show up! I thought I was the only one, and I only aquired mine recently. I am in the process of welding up cracked wheels. (front)

Well, good luck on your welding. One of the things I need to do, once this is sorted out, is to replace the front hubs - one of them is dog-eared (only 3 holes left), the other one the previous owner did some welding on. You may know that welding cast iron is tricky, and not the same as welding steel.

There's a company called Sparex that makes a lot of parts this tractor, and they have new hubs.

Here is a complete guess. From the description of the sound, it could be a splined connection somewhere inside the transmission that's worn or cracked. Attached are some parts pages. Any more details on how this developed?

I saw some hubs, I believe on ebay, for like $40.00

This happend very suddenly - one day it wasn't happening, the next it was. I don't recall any gradual happening.

Wonder if it oculd be one of the bull gears on the rear that drive the axles. I could imagine this making this noise and working in reverse but not forward. If the spur gear (turns the bull gear) has feathered it over or wore it out. Just a thought.

I reckon I'll find out soon enough. I'm going to tear the tranny apart on wed/thursday.. Here is a link to the pictures of the whole process:

Now that is a dis-assembled tractor!!!!! Was it neccessary to do all that, or do you intend to put it all back re-built?

BTW, I saved the link to the pictures in my favorites for future reference. THANKS.

I also found out by looking at yours, that the linkage that operates my 3 pt hitch has been botched. I'll have to look into that.

Keep us posted about what you find and for sure how it goes back together. (with photos)

Keep going, you'll find that tranny yet. j/k
