	I am trying to put a new rim on my CA and the eccentric locks are frozen. I do not have access to a torch. I have been shooting them with Kroil but no luck yet. Any other ideas? Should I try to find someone with a torch to heat them? Thank you in advance.

	Thak you Norm. I thought about doing that. Will the eccentric locks come apart then so I can remove the rust/corrosion.

	I have been having good luck just driving the pins back and forth with a hammer to get them loose first....there is about 1/8" of travel without removing the snap rings. It helps to have a good impact wrench to turn them with also. If you can't move them with a hammer, do as Norm says and soak them in diesel for awhile, drive or press the pins out and clean everything up good. I've also welded two 1/2" sockets together to make a wrench for the square head pins....then use a cheater pipe with a breaker bar...be careful because the heads will twist off!

	I think someone on here also stated to make sure that the eccentric you are working on is at 12 o clock so the weight of the tractor is off of it while you work on it. I used the approach of taking the whole wheel center and eccentrics apart but they can be a real pain to get all back together.

	Snake oil of choice. BMFH, breaker bar, socket and a big pipe for leverage. It does help to have the one you are working on at the top. I have got quite a few loose recently like this. Sometimes on real stubborn ones, I will have a helper put tension on the eccentric while I hit the socket with a hammer. Sort of jars it loose.

	I do as Norm recommeends; remove the centers and locks will fall out. Remove the lock rings from the back side and apply penetrating oil of choice. Initially, I used the BFH and heat torch to loosen, however due to bad experience, I now use my press (and impact gun) to loosen the pins. Once out, clean up on a wire wheel and reinstall using a lot of neverseize on the pin (bores and under the lock...but not on the lock area that contacts the rim). Reinstall so that the non eccentric guide is on the rail with the holes for the stops. When adjusting the rims, I rotate the tire so one of the locks is on the bottom and the other two are at the 3 and 9 O'clock positions and loosen/tighten the bottom one 1st.

	Be careful with the amount of torque you apply to a seized eccentric on a CA. That 3/8" square nose is not near as strong as the 3/4" bolt head on larger model tractors. I do as some have suggested - remove rim from tractor, remove 8 bolts for the 3 eccentrics and the dummy one. I put the eccentric in a vise, heat with a torch at the two narrow areas near bolt head, then immediately work the bolt back and forth with socket and breaker bar. I use the 3/8" square end of a socket on the eccentric with a long nut to join two sockets together. Don't forget to remove snapring first. Clean rust away with wire wheel and apply antisieze. Gary

	After taking them out of the rim I like to through them in the shop wood stove at night and let the coals burn the rust out, then they can cool slowly over night. Take them out next morning and they turn like new, it does not seem to take any hardness out as I hake done this to many for years. Of coarse lube well before reinstalling. Cal in Ct.

	Cal had a good idea, I'll have to try that. I took mine from a WD and soaked them in muratic acid for a week, but with frozen water now you can't do that outside and you darned sure don't want the fumes in a closed shed!! But the acid will eat the rust out of threads even!
