Hydraulic pump for 1974 D-18 hydrostatic

[David Lindstrom 0]

Restoring my 1974 D-18 with a hydrostatic drive system.  Pump is not putting out pressure.  Need a parts list for pump parts and where to get parts or can I find a working pump.

Your D-18 (D-180) is now 50 YEARS OLD.  Any substitute pump will also be 50 YEARS OLD...with likely same issues.

Take the pump off and rebuild it yourself...not difficult at all---I've done a dozen or more.  Here is the .pdf file to do that. SUNDSTRAND-Piston-Piston-PUMP-MOTOR-Refurb.pdf

The hardest part is getting it off the tractor...but you'll have to do that anyway.  

You can still get the O-ring and Gasket set online---  

Don't forget to overhaul the Hyd MOTOR too...as the wear in your pump will no doubt be cop[ied in the motor.

Thank you for the information.  It appears to be very complete.  Are the parts still available and if so, where do I order them?  Also, thank you for the prompt reply.  I am looking forward to getting this tractor rebuilt.

If you do this get yourself  a long reach socket allen wrench  Makes removing manifold bolts from pump much easier

 

Also make sure you have 5/16 and 3/8"' 12 point sockets (3/8 drive works)
