Belarus 400/420 Rear Hydraulic connections for Hydraulic Toplink

[fieldgoal00]

I'm purchasing a hydraulic toplink for my Belarus 400A tractor. I need to know the hydraulic connections prior to ordering. Does anyone know if these factory connections are 3/8" NPTF or SAE 8? I've included a picture to aid in an answer.

Are you replacing the existing female ag couplers?

No, I think I've found what I want. This one has a dual check valve on the top link to prevent and loss of Hydraulic in the toplink. I think I have the correct hoses picked out as well because they have the male ball connectors on them. Does this all look right?

While the 2" dia unit will work for you, I highly recommend that you go with a 2 1/2" unit for your size tractor.

why would you recommend 2-1/2" diameter?

With the size-weight of your tractor, if you do any work in reverse, such as box blading, rear blade work etc, you can very easily bend the 1 3/16" dia rod that that unit has.
