John Deere Cylinder repair

[Draagyn]

Howdy all,
Tonight I will be taking off one of the lift cylinders for my John Deere 148 front end loader. I am putting in a new seal kit tomorrow.

Was wondering if anyone had or knew where I could find an expanded view of the cylinder.

Also any info that may be useful along the way for me.

Thanks

Thanks for the help guys!
As soon as I got my cylinder to the bench this morning I noticed the new seals seamed to be a little small inside diameter. Sure enough, part #16 (A) that Kenny mentioned, was too small which made it extremely hard to get piston out of housing. Once piston was off the rod there was no way the new parts were going to fit on the rod. Called Deere, there is two size lift cylinders. One the same size as bucket cylinder and one bigger. Found a misc seal in bucket at work that fit inside the gland and she is good to go now! Also noticed what May have caused the seal to fail, other than being old hard and brittle, two small burrs few inches from end of rod, will check clearances tonight.
