GT14/D series lift cylinder modification

[tractorboy79 2]

I was looking around on ebay and noticed that hydraulic actuators from John Deere 312, 317, etc models appear to be Identical to a Gt14 or d series lift cylinder. My question is would a new cylinder from ebay be able to replace one that is on a gt14 or d series?

 

Images below of cylinders to show similaritys.

All you can do is try. Hopefully it isn't too expensive. 

 

Many peripheral parts on the tractors of the era were off the shelf from other suppliers. You may get lucky...

Dimensions that matter:

- Center to center on the holes in the rod and the cylinder when retracted and fully extended (confirms the cylinder will correctly operate the rock shaft)

- Diameter of the cylinder (for adequate clearance)

- Diameter of the above holes

- Diameter of the rod

 

 

Max pressure is unlikely to be an issue -- JD’s typically ran at 1,000 - 1,200 PSI which is more than the D.

Do both use the same hydraulic fluid / oil for sel compatability ??
