NB Power Steering Suction Hose no longer available
Towards the end of my MSM build thread, I recount how I had a catastrophic power steering failure on track. I've removed what I believe to be the offending leaking hose, part number NC10-32-688, pictured below:
Hose in question is coloured orange and it connects the pump to the reservoir
The trouble is, the part is no longer manufactured by Mazda and there is zero inventory in North America. I haven't had much success finding an aftermarket replacement either. Anyone know of a suitable alternative or perhaps have a spare off a wreck? My next track day is coming up and I'm dead in the water until I can get this figured out.
Good idea - thanks. I'll look for one locally here and see what I can do with it. Any issues with a heater hose carrying ATF? I guess a rubber hose is a rubber hose and there shouldn't be anything to worry about.
Grrrr! Distributor recommended against the coolant hose as it's not rated for oil. Found a length of oil-rated 5/8" ID hose at a local hose supplier and hooked it up. After pressure-washing the engine bay to make everything clean, it turns out it wasn't the hose at all but the high-pressure fitting at the top of the pump. Even after tightening, it still sprays fluid out whenever the wheel is turned. Bad pump? Bad fitting? Would replacing the crush washer perhaps do the trick? I'm disheartened.
Great. Local dealer will have one in by tomorrow afternoon. I was also able to source a suction hose from Treasure Coast, so hopefully I'll have things back in a running state fairly soon. Thanks all.
New hard line went in today. Unlike most repairs, this was actually easier than anticipated. Drop the undertray and the bottom compression connector was within easy reach. Replacement hard line had all-new brackets and was a breeze to install.
I'm still not sure why the old one failed. The upper bracket locks the hard portion of the line completely in place. It cannot move relative to the engine, so engine torquing shouldn't be able to fatigue it. Puzzled...
Anyway, thanks to everyone who chimed in. I'm back in business for the next track day.
