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 ? Just build the program for the par

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 mach

Re: [MBZ] mono-valve source

I appreciate the confidence in my talents. Now if y'all will kickstartgofundme to buy a CNC milling machine I will get right to it. I bought one of those replacement cartridges from Jabba for one of the SDs for my daughter to replace but I don't know if she did it yet or not -- I think I had

Precisely what happened with my 3 MTC mono-valves. All it takes is a pinhole. Jon > On Apr 17, 2015, at 10:47 PM, Jaime Kopchinski wrote: > > 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

Re: [MBZ] mono-valve source

With all the CNC machining capacity, it seems to me that someone, somewhere, should be able to remake the valve to take "O" rings with a new design and sell replacement parts that actually work. This problem is a matter of "when" will it happen, not "if" it will happen.. known design weak point.

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 origin

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 en

Re: [MBZ] mono-valve source

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. Brown wrote: > I purchased a couple mono-valves from the PartsGeek for my '84 300D & '85 > 300T

Re: [MBZ] mono-valve source

I purchased a couple mono-valves from the PartsGeek for my '84 300D & '85 300TD a few weeks back and found them to be Chinese junk, as the one where I opened the package had a different diameter to the cylindrical shaft such that it was a very difficult fit and didn't work at all so I sent 'em
