Jinma 284 steering pump issue

[ablett13]

Hi all

Does anyone know where I can get hold of a hydraulic steering pump diagram from? I have taken it to bits to clean it and change the bearings in it as they had collapsed and I want to make sure I put it back together right.
Hopefully someone out there can help.

Thanks

This is the pump off my Jinma 354, hopefully it's similar and somewhat helpful. I would imagine you already have it figured out by now.
These pumps seem to need new W rings about every 250 hours. I have rebuilt this one twice.
