Mike Posted July 16, 2009 Share Posted July 16, 2009 I was curious as to what color should I paint my 10 speed Duplex transmission behind the 673 P engine. I do know that the P series engines were gold in color, but did the trans get the same shot as the engine in each series ?thanksmike Quote Link to comment https://www.bigmacktrucks.com/topic/10066-duplex-paint-color/ Share on other sites More sharing options...

vanscottbuilders Posted July 17, 2009 Share Posted July 17, 2009 Mike,My 1963 production year, bone stock 673-P engine and duplex transmission are both a light metallic "industrial grayish-green" color that I have seen on many Mack engines. I have heard it called "Chrysler Turquoise" too, but I'm not sure if that's accurate.The engines must have been several different colors, as I also have two that are both a simple gray color, and appear to be original. Haven't seen a gold 673-P yet, but it doesn'tsurprise me, as the early Maxidyne engines were sometimes gold, and production overlapped.I have seen transmissions painted a dull aluminum color that looks pretty good, especiallyon the "light" aluminum cases. That's probably my choice for my own stuff.Just a guess, but I think the transmissions and engines were painted as an assembled unit atthe factory.Just tonite, I have painted one of my 711's in the medium gray color, that I think was original on thatparticular engine. It's getting an aluminum colored transmission behind it, with the emergency brake operating hardware, e-brake drum and all attached steel parts painted satin chassis black.Hope this helps -Paul VS Quote Link to comment https://www.bigmacktrucks.com/topic/10066-duplex-paint-color/#findComment-38151 Share on other sites More sharing options...

I like to stay with the correct colors if at all possible. Most car trans. were a natural metal and we used to paint them with a clear-coat. I just don't know about the trucks color's.Thanksmike Quote Link to comment https://www.bigmacktrucks.com/topic/10066-duplex-paint-color/#findComment-38157 Share on other sites More sharing options...

Rob Posted July 17, 2009 Share Posted July 17, 2009 I think that they are painted red oxide primer... Thats what mine isb61 fredAll of mine seem to be "natural". The tri-plex's are all aluminum, the quadraplex is cast iron without paint, and the Fuller's seem to be red primer.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

That was their distinguishing factor.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

HK Trucking Posted July 17, 2009 Share Posted July 17, 2009 Actually the stock color for the 673, 711 thermodynes and 720, 7220 duplex triplex and quadruplex transmissions is that "turquoise" color, similar to the "alpine green" color used on the old Detroit 2 cycle diesels.This Color Quote "If You Can't Shift It Smoothly, You Shouldn't Be Driving It" Link to comment https://www.bigmacktrucks.com/topic/10066-duplex-paint-color/#findComment-38170 Share on other sites More sharing options...
