I have a leak in the steering gear on my 656 diesel gear drive. I used the loader today to lift the front end off the ground and noticed some slop in the gear as well. Reading the manual, this seem pretty straight forward on resealing the piston and snugging up the gear. I was wondering if anyone has any experience with this and if you have any pointers or tips. Also, do I need to get these seals separately, or is there a kit?
