Nissan D21 92 Hardbody Utes Summer break, long over due maintenance of front wheel bearings, engine / radiator / PS flush and clean)
So, PS, Replaced gaskets and seals , reinstalled , bleed system according to Haynes manual but now PS seems to be not working fully. Seems OK for first part of turning then half way to full lock it gets quite hard. Tried a second bleeding by having wheels off ground and with motor off, turned wheel full lock to lock 10 reps which got some fine air bubbles to the reservoir.
We are not sure if something flew out and didn't notice from the High Pressure Line Out when I removed the bolt from Flow Valve Assembly.
When assembled this part, it was: SPRING - FLOW VALVE - WASHER - BANJO - WASHER - BOLT
Pump has sticker reading: unisia NISSAN 49110 44G10 (last numbers are stamped on)
