Keith Old Seal Kit 3.5″ Cylinder Metric

Description

Keith KRFII 3.5″ Cylinder Seal Kit

Older than 2009*

One seal kit rebuilds both ends of one cylinder.  To know the size of the cylinder, measure around the casing or the bore of the cylinder.  A 3.5″ measurement means you have a 3.0″ Cylinder and a 4″ measurement means you have a 3.5″ cylinder.  A 4.5″ measurement means you have a 4.0″ cylinder

The seal kit includes all necessary items required to rebuild the entire cylinder. It does not include items such as the Rod or Piston. (from Keith Manufacturing KRFII Owners Manual)

Cylinder repair:  To repair or replace the cylinder, you have to remove the check valves on each end of the cylinder that will be removed. Loosen the bolts from the check valve beside the one being removed. This is so you can swing the hydraulic cross-over tubes out of the way. There will be a total of twelve 5/8” bolts. Each end of the cylinder will have four and there will also be four bolts from the cross-drive. Leave one bolt on each end of the cylinder to hold it in place, but loosen it so that it is almost out. Have one person on each end of the cylinder remove the bolt and let the cylinder down. Use the same method to put the cylinder back in. (from Keith Manufacturing KRFII Owners Manual)
