Combines header lift cylinder rebuild

You will have to remove cylinder from combine,then put it in a vise or some way to hold it,remove fitting and with a light you will find heavy snap ring when you move rod of cylinder back a forth and rotate till you see the ends,with a screw driver pry the snap ring into deeper groove beside snap ring( you will have to rotate rod while doing this),then just pull rod out and replace parts and reverse to install.Make sure you get the right seal kit for size cyinder that you have,there were two different sizes.

Thanks a lot George for the quick response! My parts book doesn't show a snap ring on the piston rod so I wouldn't have thought to look there. How about the lock ring at the front of the cylinderIJ Any special tool or technique to remove itIJ Any special driver to reinstallIJ I had planned to use a piece of 3" pipe. Thanks again.

There is only one lock ring on the back end of rod,Cylinder consists of outer barrel,piston rod,dust seal,oring,rubber backup washer and locking ring.When you get cylinder off of combine and remove the hyd. fitting you will see the ring on the back end of rod when you get it in the right place,you will not need and special tools for the job.the rod will just pull out by hand and after you install the new parts you can carfully slide it back in,I coat oring and end of piston with grease so it will slide thru oring and seal without cutting anything.If piston has some scratches on it you can polish it with some fine emery cloth.The biggest part of the job is removing the cylinder from combine and installing it.

JIW, If cylinders off of a R62 would work. I have a set that is in perfect shape. I had to take them off and put the bigger ones on,when I got a 12 row corn head. Give me an offer if they would work and there yours. As they are just taking up shed room.I live in south central Ill. later, Illinois Gleaner

The kit for the rebuild is expensive, but it is easy to use. Just follow the instructions in the parts book. I am a feeble mechanic at the best of times, and even I can do the rebuild. Ended up with lots of hydralic oil slopped all over the place though, so I would suggest having lots of replacement oil available, for use when the job is done.
