I would suggest you find someone that knows the procedures and does the job correctly.
You have multiple issues on those tracks and track frames.

If you can - take some pictures and post them of the inside of the tracks where the Bushings sit between the rails. Those round portions that fit into the sprocket.
You can also feel them with your fingers, see if they are round or flat on the track pad side.
Let us know.

Hello frens,

The master pin right track is being held by a cotter pin and it’s very squeaky I am attaching a video.

Here are the photos and videos of the center spring bolt mess, I hope the photos won’t upload out of order I am on my cell phone first photos are right side then left side and also some videos 

right side video:

left side video:

youtube.com/shorts/WXVFP-B0JEE?feature=shared

Master pin right side video:

youtube.com/shorts/dTof5ij_OmI?feature=shared

inside track bushings look ok to my untrained eye:

youtube.com/shorts/H5_3qeVZmyo?feature=shared

the center springs look like they are being held by the pressure itself rather than the bolts, look like a disaster waiting to happen I would like to find a photo of how they are supposed to look

what do you think ? Looks bad except the master pin it looks ok because it’s not welded so I’m thinking finding the right pin and installing it is the way to go but what worries me are the center bolts  

Jose

Sorry to be negative here, wish I had some great news for you.
I do not like what I see in your photos and video.

First off - the master pin is a lost cause, purchasing a new correct master pin will not fix the problem, the rails (chain) is ruined by that excuse for a fix. Master pins are a very tight fit and are driven in place, not something that is loose or free floating. They are held by the tight fit in the rails, no cotter pins.

As was said earlier in one of the posts, the track will need links replaced to correct the master pin issue. If what I am seeing with the bushings and rails, a reputable shop will probably suggest new tracks. It does not appear that the tracks have had the bushings and pins turned but it may be way too late to consider that over new rails. Finding a place to do that work will be hard and expensive. Turning pins and bushings will help extend track life but is only if the rest of the track chain is acceptable.

Rear Sprockets show a lot of wear, that would concern me with the expense of replacing rails (chains) without new sprockets.

The carrier roller shows lots of wear, I can not tell if it has flat spots or not. That being said, the bottom rollers will need a good inspection too.
If you do remove the track with the master pin failure, be sure to address the condition of the bottom rollers as it would be the time to work on them.

Those recoil springs are just waiting for an excuse to release. DO NOT ATTEMPT TO ADJUST THE TRACKS without those springs properly secured.
This is a job for a properly equipped shop, not something you want to try without experience and proper tooling. The threads on the track adjustment screw look terrible, not sure you can back them off if and when you get the recoil spring problem corrected.

You have some great people on this forum and understand it is very tough to get a real feel for something just by photos and videos. They will certainly do their best.

I am sure you will have some other suggestions and comments, you have a lot of work ahead of you, and nothing to do with track work and sprocket replacement is cheap.

i think the main problem is the springs center bolts i will do some research first and will fix it myself as I always do with all my machines, I am not enjoying this discussion board too much tbh because i am more of a diy kind of person so I wont be around here too much anymore

thanks for everything

Captain B, You definitely will not be around anymore if you make a mistake with those adjusting springs!!

Only a fool would reject all the helpful advice from the board members that care enough about you to save you from yourself.

My 2 cents.

Wishing you the best of luck and do understand fixing it yourself.
Many here are DIY people and fortunately this community on the board is very much into helping each other as much as possible.
The knowledge base is one of the best you will find, especially dealing with Caterpillar.

Hang on!
The center bolts are used to keep the spring compressed to install it.
After it is installed, the nut is backed off so the bolt is loose.
Now the bolt is used as a safety in case the spring has broken, keeps it from coming out.
So, if the bolt you took out will thread back in you are good to go with the springs.
Now as far as your tracks and sprockets they're in pretty good shape.
Now the master pin needs to be fixed, it's not long for this world.
Too bad you're not a little closer, I could replace the 2 track links for less than 300 bucks but the travel would kill you .
I do this kind of work for a living so if you would like to talk about this send me you phone number and a good time to call in a private message.
In any case good luck
Bob

For some reason I cannot view the videos. Bob has given you some good advice . I can't see the master pin but a pin secured by welding or other means is not the end of the world. I have even run a bolt and nut to get by. Don't give up on us. We are not all purists and safety cops. I am more interested in the end results, brush clearing and farming. My great grandfathers ranch is growing up to brush and needs clearing too. Your tractor would be an upgrade for me. As far as safety I am more concerned about herbicide use.
