Hey guys, I seem to be having a love hate thing with my power steering hoses for the 65!
Photo attached, they seem to be leaking no matter what I do, I have used plumbers tape, taken them on and off a number of times, they are new but there must be a fault . They thread on beautifully, but just keep leaking from where the screw driver is pointing, this is with both hoses. Should I just buy another set of new hoses or can you suggest anything I should try?
Looking at the condition of the nuts and the lack of spanner marks, I suspect you may not have tightened them sufficiently to seat in the acorns. I suggest you tighten them a bit more than what you did, then loosen them and tighten them again, Do this a couple of times. If they still don't seal, it's time to replace the acorns in the control valve.
My Motto - Don't get Caught! If you do, Blame Someone Else!
Agree with the above comments. Now using the correct flare nut spanner, fit one hose & tighten, then remove & do the other. That way you will get each joint to fit correctly (as Nuts has said), making it easy to fit both ends & seal, in the final fit up.
The correct spanner type (if you already did not know) ........
Also note there are flare nut spanners and flare nut spanners. Don't buy a cheap no name brand set as you will inevitably damage tube nuts. Compare a set of Sidchromes versus a no name brand and you will notice the difference and why they are generally successful in dealing with stubborn flare fittings.
The hose seats are soft aluminium which can be scored easily so be very careful not to rotate the fitting whilst final tensioning the thread. Hold them steady in the correct positioned with respect to other hoses and valve body then lock up hard. The seats are pretty easy to remove just screw a tap in and wiggle out. Be very careful re cleanliness hydrualic systems don't like trash.
Google stangers site he sells the hose seats ( and all other steering rebuild kits).
I have just had the control valve rebuilt, is it standard to do the seats during a rebuild? I might pull it all out and attach the hoses. I belived I did them tight, will go tighter but is there is a risk of going over tight? Are the acorns the seats mentioned?
Will look up stangers to get the seats!
Will let you know how I go, cheers
Tightness will be limited by rounding of the nut with your flare spanner basically. Bit of a feel thing with hydraulic lines usually then just check for weeps.
Unfortunately not all rebuild kits come with seats that is why stangers site is my preferred supplier and use oem quality sesls etc. A reputable rebuilder would have replaced but you don't really know. Pull it shine a torch on the four seats and check for scoring or nicks.
You really don't want to over tighten, you can distort the flare or seat, or gall them.. then they are only good for the bin. as the Shop Manual says, in bold Do not over-tighten.
Seat them "firm". If they leak, back them off, re-seat. Don't just keep going tighter.
Some shops do not replace the seats during a rebuild. Pull the hose, look at the seat, if it is not a smooth and clean surface, replace them. Any galling, scoring or distortion can make them impossible to seal.
