Mk3iain Posted February 22, 2019 Share Posted February 22, 2019 I have an oil leak from the input seal on the steering box, having noticed oil coming out the top of the steering column. The parts book only shows the box as a unit and does not show any internal detail or parts. I have sent an email to Adan Hydraulics as they are shown as manufacturer, but no reply yet. It's been nearly 50 years since they made it. Has anyone dealt with these or got any information, I am not sure if it can be repaired? All help appreciated. Many thanks Iain Quote Link to comment Share on other sites More sharing options...
snort Posted February 22, 2019 Share Posted February 22, 2019 I did manage to buy a new box from them about five years ago, about 250 quid I think. they were very helpful at the time.I wouldn't recommend trying to repair it as I understand it can go horribly wrong.However there are some clever people on here. Other vehicles also had them on but often different gearing, I once 'borrowed' one from a sugar beet harvester and needed twice as many revolutions of the steering wheel to get round.

Mk3iain Posted February 22, 2019 Author Share Posted February 22, 2019 Let's hope they still have one or can tell me how to fix it, I had hoped it would be a simple seal change :-/ Did you open up the one you removed? Iain Quote Link to comment Share on other sites More sharing options...

Mk3iain Posted April 28, 2021 Author Share Posted April 28, 2021 I tried contacting Adan Hydraulics but sadly got no response. Now have removed the unit to find it is a Danfoss steering unit, Type OSPB 315 ON. NR. 150-0030. Just need to find the correct shaft seal or overhaul kit and service instructions. Lots of stuff online but a lot of different variants... Now I've got that out for fixing (hopefully) I can look at the clutch and brake master cylinders and no doubt end up with a complete vehicle rebuild. 😕 Quote Link to comment Share on other sites More sharing options...

Richard Farrant Posted April 28, 2021 Share Posted April 28, 2021 From recollection of the Eager Beaver parts book, the power steering unit was under a Coventry Climax NSN, I can see it is a Danfoss, but likely a unit fitted to a Climax forklift in military service. The Eager Beaver was a 'parts bin' vehicle made up of parts from a number of different make vehicles. Quote Link to comment Share on other sites More sharing options...

In the parts book its down as supplied by Adan Hydraulics using part of the Danfoss number, they would not reply to requests. I'm glad it turned out to be a Danfoss part as there is much more chance of getting it sorted, hopefully. Quote Link to comment Share on other sites More sharing options...

I have used it to strip my unit down and found the expected duff seals and a broken neutral spring. I've also contacted a couple of firms for parts but await their response, just as well I'm not in a hurry. Looking at it spread out I am trying to understand how it works....🤔 Quote Link to comment Share on other sites More sharing options...
Mk3iain Posted May 5, 2021 Author Share Posted May 5, 2021 So far I can find the seal kits in the UK but springs are a 9 week lead time. I have found a supplier in Germany with both in stock as well as the steering unit complete. Danfoss : 150-0030 : OSPB 315 STEERING UNIT - Holstein Hydraulik Shop These things are not cheap ! The parts for future reference are; Seal kit, 150N4040 Spring kit, 150-4207 I'll just get the parts ! Quote Link to comment Share on other sites More sharing options...
Mk3iain Posted May 16, 2021 Author Share Posted May 16, 2021 (edited) Here is the seal kit and spring set as received from Germany. I have rebuilt the unit as per the manual except for fitting the shaft seal as I don't have the correct tool but it fitted ok. Now I have a problem, with the engine running and hyd pressure to other functions such as mast rams the steering has no hydraulic assistance. I can turn the wheels with great effort as in the emergency mode, just, but it seems like it has no hyd pressure. There is a buzzing from the pressure side, maybe the steering prv ? Anyway, first things first, the filter is showing half green/red when running so its drain the system again and change it. Does anyone know the filter number ? The book shows "filter element, fluid pressure. drawing number. 920-A-Z25" Edited May 16, 2021 by Mk3iain Spelling.. Quote Link to comment Share on other sites More sharing options...
Mk3iain Posted May 16, 2021 Author Share Posted May 16, 2021 I've pulled the filter, after removing the assembly and tank and... Anyway, the element is full of brown slime and horrible, so was overdue replacing. It is a "Fairey filtration, replacement element 920P225". Does anyone know of equivalents ? Many thanks Iain Quote Link to comment Share on other sites More sharing options...
Mk3iain Posted May 16, 2021 Author Share Posted May 16, 2021 A picture of the element. It is naturally brown in colour but the slime that also came out was a near match. It will come off easier next time, hopefully. Quote Link to comment Share on other sites More sharing options...

There are original NOS Fairey ones on eBay in Germany but I definitely think it better to use more a modern (and newer) equivalent ! Quote Link to comment Share on other sites More sharing options...

As an aside, I found a label from BI Engineering under the engine cover, an interesting company. Quote Link to comment Share on other sites More sharing options...
Mk3iain Posted May 24, 2021 Author Share Posted May 24, 2021 While sorting the steering I have removed the oil and fuel tanks, drained the gearboxes and am doing a few other wee jobs, so far... The level indicator for the fuel tank has always leaked a bit when the level is high and is stained making the level hard to see. Ideally I would like to replace it but cannot find another, yet, or could it be repaired and cleaned ? It is 505mm long with the holes 475mm apart on centres.
