My dad got so mad at the last set he took a thin cutting disk and cut into the outside of the bushing pad side. Parked it in a wet spot for a month rotating the tracks everyday with the bucket and backhoe stabilizers down. This finally broke them loose but are still a bit sticky. These were brand new sealed (not lubricated) rails that were on a Dozer cat we bought and had sat a long time. They will never get worn out on out yard cat so no issue with dirt getting in the bushings.

We have also built a pressure unit out of pipe with an end cap and a flange that just fits a 450 rail. We tried with oil at 1,000 psi for a month on a track chain and didn’t work. My dad wants to try antifreeze which we used from a local truck repair shop. I want to try water or an ATF/ Acetone mixture. We have many sets with frozen up links.

We also have a few sets soaking in the pond which we will pull out before it freezes , install and see if they break free.

Got it pressure washed and ran it for 20 minutes in water and only one broke loose so far. Got it soaking in water now and will work them a couple times a day and see what happens. Hope it works

How much do new chains normally cost.

JWB, I did try the ATF and acetone a few months back an that didn't work either. I juiced it up twice a day for a few days and it didn't help either.

That price is per side not for a pair! I priced pads, chain, sprocket ring and nuts/bolts about a month ago and the cheapest I could find for a straight 350 was 1638.32 a side.

They would need to sit in water for a couple days minimum, week is probably better. If you can drive it around in the water, that is even better once they have loosened up.

I have it jacked up with a make shift pond built under it. I have part of them under water now and will let them soak all week then try it again to see what happens. Then I will soak the other ones the same and hope for the best. If this doesn't work then I guess I will see what it cost to have them punched out.
Thanks for all the help.

Buy a couple soaker hoses, lay the hose on top of the track, with a few sand bags laid on it to keep it in place. Turn on the water just so the the rail stays wet. Leave it alone for a week. Remove the hose and sand bags and exercise the the track. This worked on a friends 350 loader. It took three weeks to get the pins and bushings freed up. But it was not alot of work for him.
