I purchased the rebuild kits for my bucket cylinders. One was the old kit (dealer stock) and one was the new part number, AH176272. Well the new kit is $24 dollars more expensive and it did not contain all the parts of the old kit, at least not for the 200cx. So I also needed a rod seal kit ahc16980 to complete the rebuild. I was a little irritated to say the least but they are done except for putting them back on the loader. So if you rebuild yours be aware you will need two kits.
