These are high quality replacement o-rings to reseal most travel control valves on Case Ingersoll Machines. Part numbers #, 4X C28856- A7982, 2X C28217-A27365, X2 211-5 BALL,  X3 211-7  BALL X1 211-9 / 211-208  BALL
 
These O rings are  a wear item and should be replaced over time. If you are experiencing hydraulic issues and can not pin point them this inexpensive kit maybe worth trying. And will give you a peace of mind that your seals are good now for years to come under normal operation.   If you used the wrong fluid in your system or had a failure these seals should be replaced for sure.
       Included also are the balls for most all travel valves used on Case Ingersoll Tractors and Loaders. Balls are for Relief valves and detents. The Smaller O rings are for the travel and lift spool. The larger 2 are for the integral built in holding valve on all models after the mid 80s. These are a pretty simple install but we highly recommend taking the valve off the tractor.
NOTE- not all valves will use all the o rings or all balls.
 
There is also a OPTION to add a power Beyond Seal kit, some Tractors and many loaders sespecaily 644, 646 and 648 used a large Power Beyond port on the side of the travel control valve.  Power beyond was also used on some garden tractor models.   Parts Numbers used/replaced in this options can be X1 C28752- A64436, X1 C26669, X1 A30097, X1  218-5007
