Hino Rb145A power steering

Quite few Japanese motorcycles used to have odd sized seals, so you had to go genuine. If you know the size you could try some of the bike shops that still have an old mechanic.

Ha! definitely sprung.

Bruce, maybe this one:
Its a dual lip, double spring.

OK, remove the hose that goes into the suction side of the pump and put the end into an ice cream container, when topping up the tank, does the oil flow through easily?
If yes, look into the pump inlet tube and see if there is anything blocking it or a fine strainer filter that is blocked
If the oil doesn't flow easily, remove the hose from the tank and try again.
If it flow easily now, the inner wall of the suction hose has collapsed and is restricting the flow, replace the hose and try test 1 again.
If no, remove the tank and if your unit has a removable top, take it off and there should be a filter over the suction pipe outlet, remove that and find a replacement. Wash the tank out to get all the crud out, replace the pump suction hose anyway, just to be sure, and put it all back together.
Before you refill with oil, remove the oil return hose and put it in a large container, jack up the front axle, have some one pouring oil into the tank while you start the engine and rotate the steering lock to lock a few times. You might need to turn the engine off a few times so the tank filler can catch up and possibly empty the catch container.
Continue this circus until the fluid runs clean, then stop the engine, reconnect the hoses and run the engine while turning the wheels lock to lock and your assistant filling the tank. This might require a few stop/starts as well while the air bubbles settle out of the oil if you ran out of oil in the tank while doing the system flush.
Once the level stabilises and you can feel the power assistance helping with the steering, lower the front axle to the ground and try the steering now with weight on the wheels.
No matter what the result, both you and your assistance should sit down with your favourite beverage and either celebrate or drown the problem.

Let us know how this fix goes

Thank you T1 Terry.....I can follow all that .....
I was surprised today to find that all was working well......drove it around town for half hour or so an it performed without concern.
The tank did not over fill soooo.......what the hell Maybe air escaped out of the system as i had left the cap off the tank over night..
Maybe it was low on fluid when the problem first appeared ...
I will still try to source a kit before i do any more . It is probably a good idea to clean the tank and filter when i next have to do anything to it .
I am not convinced yet that all is well but time will tell.

Thanks again for taking time to reply
Hopefully we will get to Mannum one day and meet you all
Cheers Vic

PS I am having one of my favourite beverages now.(Tooheys Old)

The kit will just be a couple of o rings and an oil seal.

Curiously, Tooheys Old is a favorite too.

[VicA]

I have sourced a kit ....just need to get it now ...then i will be prepared to attack ....first as per Terry's instructions ....plenty of other things to do around here ....
cheers

Hi I followed thru Terry's procedure and found that fluid was not be circulated thru the lines ....Pulled the pump and flicking it around in my hand felt ok ...so primed it with fluid and it pushed fluid out with some pressure .....could feel suck and blow in the right places ...so put it all back together and and followed the bleeding procedure .... and low and behold all works fine .....going for a good drive this week to Omeo so that bendy road should give it a good work out ...
Thank you all
cheers
