Detroit Diesel 16V92


1000 HOURS!!! Detroit Diesel 16V92 Custom CNC Exhaust Manifolds (Header) DPUK
DieselPumpUK

Industrial machinery is getting out of control. Who am I kidding? It's been out of control ever since they started smelting iron. Now it's just running riot. I would have thought that you could buy a new diesel engine to replace this antique 16 cylinder monster for less than this custom machining project cost, but who knows how much work it would take to fit a new engine to the old job? The pump needs to be running, fitting new exhaust manifolds is going to be easier than replacing the whole engine, and you can do it this year? Great! Git it done.

I do wonder how they bored out the passages in the manifolds. That seems like it must have been tedious. 

P. S. I left him a comment about flame spray welding.

I will bet that the manifolds were made in 2 or more parts, then welded together and the outside machines back to smooth

B - I didn't even think of that. I was enamored of the 'four months of CNC work'. I was thinking they must have had some crazy 'drill around corners' tool, but in spite of all the crazy things they can do with CNC, I don't think they have mastered that one. You must be right.
