Has anybody identified the OE manufacturer or source for the highly sensitive air valve block? It seems insane that dealers charge ~$900 for this small, but intricate, part. I fully understand the methods for attempted service/repair, but they seems to fail beyond repair quite often from feedback I am getting from two dealers.
You won’t buy the whole valve block. I don’t think it’s supplied like that, but probably assembled by Radical (or a sub assembly supplier?)
My valve block needed the normal maintenance covered elsewhere in the Forum (opened up and the small screws tightened to stop the air leaking and preventing the compressor running too often) and while it was apart I took down the valve part numbers and identified them using SMC’s (the OEM of the solenoid valves) online catalogue.
see pictures below. I purchased one spare valve (there’s three in the valve block, one for upshift, one for downshift and the final one for the throttle blipper) and a bunch of the seals/gaskets that sit between the individual valves and the distribution manifold that’s also in the aluminium valve block.
it cost me ~$140 Aussie dollars or about $100 US.
