hydraulic pipe

Post by ginger dave »

Just changed the rear spheres on my E reg bx 1.6 RE.I noticed that there is a slight leak from a pipe which runs from the hydraulic reservoir to the pressure regulator.It appears to be leaking where the flexible pipe is connected to the metal union which in turn is bolted to the regulator.Are these pipes availalble new or second hand?.Also to change the octopus assy.does the engine have to be lifted to make access easier?Thanks

There's a return pipe from the pressure regulator to the reservoir via one of the octopus assemblies - but as a return it doesn't have any metal union that I'm aware of. These unions are normally on high-pressure pipes only. It's not by any chance a u-bended loopback pipe which comes back to the regulator again?

If it's a high-pressure pipe you may just need to replace the pipe seal (with one of the larger-size seals). This is , of course, irrelevant if there's damage at the point where pipe and union screw meet.
Also to change the octopus assy.does the engine have to be lifted to make access easier?
That's one of two ways to gain better access to the large octopus, though it requires care in making sure all supports are adequate from a safety point of view , despite the fact that the engine should drop back onto the mount should your engine support fail. Crushed hands wouldn't be nice.

The other is to remove the driveshaft on that side. You can of course do both.

If considering shortcuts with the driveshaft, remember that if you split it midway you run a considerable risk of losing the needle bearings in the intermediate joint....
Back on two wheels and pedal power for the moment.

If I'm thinking right ?
Is this pipe the tapered thick wall rubber transition piece that's fitted to the base of the pressure regulator which is approx. 50mm long and which the small clear pipe that's connected to it ?
As these can sometimes fail (With age) with a very small hair-line fracture which is hard to spot as once happened to a BX of mine !
I just bought a new transition piece from the main dealers for a few quid swapped it over and the leak was sorted out :D
The culprit is the the one shown in the photo below in the bottom right-hand side of the shot which has the small jubilee clip fitted on the clear pipe end, is this the same part which you are referring to ?

I might be talking bollocks ,il have to have a better look at the offending leak cos neither of these replies looks like the problem i have.The cars 500 miles away in France ,il have a proper look when i go back in a couple of weeks,thanks again.
