Rob Posted February 27, 2019 Share Posted February 27, 2019 Not afraid to use this one at the drop of a hat.

That's an ESI+ not an ESI. 2 oil filters for ESI, 3 for ESI+. Different capacity oil pans. ESI + pan is 56 quarts of oil, 25,000 miles between oil changes. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/55835-make-money-with-gold/page/2/#findComment-416784 Share on other sites More sharing options...
seyser Posted February 27, 2019 Share Posted February 27, 2019 Oops yes that’s correct. I forgot to add the plus. Does anyone know which was more popular back in the day, the ESI or the ESI+? I see trucks both ways so never really know.

JoeH Posted February 27, 2019 Share Posted February 27, 2019 I'm only 29 so I wouldn't know. I'd guess the ESI + would be more popular on a highway tractor where you're logging a lot of miles, whereas local dump trucks and concrete mixers would have the ESI where your oil pan will sit higher from any off-roading threats. That'd be the biggest decision factor if it were me. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/55835-make-money-with-gold/page/2/#findComment-416793 Share on other sites More sharing options...

The old v8's, silver was Thermodyne and Gold was Maxidyne. Before that the color was a green drab that was on most mack engines up to 1965 or so. I do remember the blue, red, gray and black engines and a few copper.

Rob Posted March 1, 2019 Share Posted March 1, 2019 I read someplace that our favorite government agency, (EPA) had a hand in it. VOC, and lead contents are most likely the leading culprit. My 72 R-685, (ENDT-675) had a red engine as built. Don't know why or if was special ordered that way but most I'd seen were gold at that time.

I had gold V8 emblems on one truck and it was a 1972 Maxidyne. Wonder if that is what it meant as well. The Gold color on the Maxidyne engines is what I remember but as Rob is saying they quit using Gold and went to other colors apparently because of an EPA issue.

j hancock Posted March 1, 2019 Author Share Posted March 1, 2019 Here is the response to the gold dog question courtesy of Randy (1958 FWD), Harvey Eckert and Don Schumaker. Basically different years had different criteria. As promised, I emailed Harvey Eckert, who corresponded with Don Schumacker (who many of us know to be the Curator of the Mack Museum and the Archivist) some time ago, and kept the response, which Harvey was kind enough to send back to me: Don writes: "The Mack Bulldog ornament was patented in October 1932. It was released as Part Number 4BF26. In December 1937, it was redrawn and the part number changed to 27RU217. This was a chrome-plated zinc die casting. It did not change until December 1941 when the finish was changed to a painted #775R Mack Gray finish. In September 1944, the finish reverted back to chrome-plating. In September 1947, the part number was raised to 217RU217A; the attaching studs were changed to cast-in female thread brass fasteners. The P1 version was chrome-plated. In June 1967, the 14 karat gold-plated P2 was released. In June 1968, the gold plating was replaced with 14 karat gold alloy. In December 1979, the ornament was redesigned to incorporate shorter ears and tail to make it more friendly when using it as the handle to tip the conventional models’ hoods. The part number was raised to 217RU217B and the patent number was changed from 87931 to 1,387,477. The P1 part was again chrome plated while the P2 finish was “gold flash.” Starting in 1966/1967, the original “gold” ornaments signified that a vehicle featured the Mack Maxidyne engine and Maxitorque transmission. All other Mack trucks used the chrome plated ornaments. Starting with the introduction of the CL Model in 1990, CH and CL vehicles with the high-level interior trim package utilized the gold ornaments. Starting in 2007, the gold ornament indicated that a vehicle had an all-Mack powertrain, i.e., Mack engine, Mack transmission, and Mack axles. This is its current usage. Let me know if we can be of further help. Thanks, Don Schumaker __________ Further thoughts by Superdog Mike. "Damn I hate to argue with the info Don sent you,but the all Mack component gold Bulldog started way before 2007,I'm certain it was as early as ''95 or 96 but I do know for fact it was that way in '97 as I had a new gold dog '97 CH613,delivered Dec.,1996,E7-427,T2130,and 4:17 Mack rears. Also I didn't think the patent # changed until sometime much later than '79,Newest truck I have to check is my '88 and it still has good old 87931 proudly printed on its chest." _____________ J Hancock looked up the patent info on the new dog change. "A search on the patent number indicates that Mack had a filing date of 9/6/1985. The US Patent Office issued the registration #1,387,477 on 3/25/1986. Couldn't find any info on the date when the new number started going on the trucks." Quote JimIt doesn't cost anything to pay attention.

Rob Posted March 1, 2019 Share Posted March 1, 2019 I've never seen a gold dog on anything that didn't have a complete Mack "Maxidyne" driveline myself. Used to work on a lot 1968-1983 R models and anything that had a gold dog was a Mack powertrain complete. My 1973 RL-797LST, (water wagon) is a Mack powertrain front to back and has a chrome dog but is not a "Maxidyne" series engine. The 1974 RL-797LST has a Mack engine, Mack transmission, but Rockwell SQHD rears on Reyco spring suspension. It has a chrome dog also. The 1977 R-795S has a Mack engine, Mack transmission and is on Mack rears. It originally had a gold dog on the hood but is currently chrome. The gold was replaced when it was swiped, (I'm told). I know both of the RL chrome dogs are original to the truck as have researched and spoken with the original owners/purchasers of these vehicles. All that being said I cannot input on anything newer than about 1984 as I've not really been around them except collision repair and modifications giving very little attention to originality.

lyneevren Posted October 13, 2021 Share Posted October 13, 2021 I recently also decided to repaint my tractor. Still, when I started the process, I identified several malfunctions in the car itself, and after a couple of days of work, it stalled altogether. It is not surprising because he was already many years old. But at the same time, he was a crucial figure in the cultivation of the land on my site, and I have not yet saved up money for a new one.
