Re: [MBZ] mono-valve source
Why own a CNC ? Just build the program for the part and rent production time. There are loads of small [relatively] shops that have excess machinery capacity now because the economy is in the tank. Production demand is down, but the machine sets there costing space and money.. I'm on several machinery auction lists, every day there is another shop doing a bankruptcy sale because they couldn't get enough orders to keep the machines busy. Rent time, make parts, sell them.. Unfortunately, for the rubber part, it would require a set of molds. Last time I had a mold set made, it ran a bit over $120,000, so recovery costs would require volume production and sales. Yet, there is likely a work around on that, I just haven't thought of it yet.

Re: [MBZ] mono-valve source
I have seen some instructable-type things on making molds for rubber or silicone bits, I would think with a CNC machine that it would not be too hard to do it, and to bodge up some injection equipment. --R On 4/18/15 12:24 PM, G Mann wrote: Why own a CNC ?

Re: [MBZ] mono-valve source
I went through 3 chinese junk monovalves when I first got my 300D. Rusty finally sent me a real MB part, and it’s worked perfectly for the past 3 years. I also went through 2 chinese (junk) aux pumps at the same time. The motor tends to separate from the pump spraying coolant all over your engine compartment. Buy original MB parts.

Yep, MB parts only in this case. Bosch stopped making them so a new supplier stepped in, with a higher price. The Chinese ones are junk, as you discovered. Jaime On Thursday, April 16, 2015, G. M.

Re: [MBZ] mono-valve source
I think the issue with the MTC (Chinese) parts are the rubber quality. Coolant gets past the sealing and into the moving parts of the valve. This causes the valve to get somewhat hydrolocked and not pulse open and closed properly, resulting it too much or too little heat. The failure of an original part was a tear in the rubber at its thinnest section, resulting in the same.
