Ian,

I took it to AIS in Lansing, and they say it needs new everything, to the tune of $1753. More than I was planning on spending on it.

I started tearing it apart, and found that at some point the head/bearing had pushed out farther than it should be, and the snap ring that holds it in place was partially in the o-ring groove, and partially not. This had taken a few chunks out of the head/bearing. I knew that this was going to need replaced, and getting it apart was going to be tougher with that ring like it was, so I took it to AIS. I have been calling all over, with no luck. The following are part numbers I have:

196 802-A is the bearing/head. This is the part I need the most. I can re-use the rest if I can just get this. According to my parts fiche, this part was used in all of the cylinders on the 15' backhoe of a 1600 and 1650 industrial. So even a stabilizer cylinder would get me the part I need.

The cylinder that needs to be replaced/fixed is the crowd cylinder, but it is exactly the same number as the boom cylinder. I have 4 numbers for that cylinder, as later ones had a thicker barrel wall, and my book does supersede them to White numbers. They are:
196 856AS
197 289AS
25-100 1748
25-100 5786

AIS said the barrel was scored up. That number is 197 290A if you should be able to find one.

I am going to call AIS tomorrow and get the cylinder back. I know enough guys that work in machine shops that I should be able to get someone to turn a new cylinder head/bearing for a reasonable amount. I just figured if I could get a good used one or the parts to fix mine, that would be easiest.

Also, the measurements of the cylinder are:
2&quot; rod
4&quot; bore
45 1/2&quot; pin center to center collapsed
1 1/2&quot; pins

I'd have to measure to find the actual stroke length, but I don't have the cylinder here.

Thanks for any help you can provide.
