I have the service manual for the Case 2090, but wondered if someone had experience rebuilding these (Case 2090 steering cylinder) and might be willing to share some pointers and/or things to look for. The book talks about using a spanner wrench to separate or unscrew the two cylinder tubes. I do not have a spanner wrench. Will a vice and a pipe wrench work OK? I do have the cylinder removed from the tractor. Thanks for any ideas. PS - I have rebuilt John Deere combine steering cylinders and throat lift cylinders.
