BP-51 Rebuild Mileage Poll (1 Viewer)

[linuxgod]

I’d be interested in the parts list to build this. I like my BP51s but they definitely softened a bit after ~6 months. I’d love to be able to check the pressure and top them off

I got the cylinder and N2 refills from a local welding supply shop. If you buy used make sure the “hydro date” isn’t expired.

The fill adapter has a special chuck that screws on to seal the space, then the pin screws in after to open the circuit.

For the pressures we’re talking about a basic air line would work, but AC hose with -AN fittings is a much better setup.

That doesn't look like "not much $" to me...

I think it was all under $400. Considering the suspension cost roughly $3k..

I suppose you're right. It bothers me to spend so much on this, then have to deal with maintenance so much. Looks like an annual process.

So ... What pressure do you set them to? Should I call ARB and ask them?

Thanks again for the help.

Yeah I’d talk to ARB, we can’t assume the pressures I used in my kings apply here. I’d also make sure messing with pressures doesn’t somehow impact a warranty if you still have one. Based on how they “supported” others for their inspection and rebuild I wouldn’t put it past them.

Spec is 2000 kPa, call it 290 psi.

Thats some high pressure

There is a Parker zero loss fitting that you can use to build the setup. I built my own, but used a ~12” paintball 1/8” npt hose immediately following the zero loss fitting so you don’t have to deal with getting that entire setup onto a schrader fitting under a truck, or in my case onto a dirt bike shock.

But, all said and done, definitely close to $400 with tank, regulator and hose.
