I recently purchased an 8N tractor with a loader. The Loader says Ford WM3. The previous owner replaced the hydraulic ram that attaches to the bucket with an incorrect ram. The cylinder isn't long enough to enable the bucket to dump. It will not move past level, and can't tip down. I don't have the original ram, and am looking for information as to size, and general specs for this ram. I have found downloads of owner's manual, but it doesn't give enough detail for me to be able to purchase a replacement ram. I have ford parts number, but it appears to be obsolete. Any help is appreciated. Thanks.
