Popular Post Supermutt Posted December 1, 2023 Popular Post Share Posted December 1, 2023 Good morning all, So I have been looking for a Superliner (E9) for about 2 years now. In one way or another I have looked at close to 100 of them. I have just come across this field find. All I know right now is it is an e9 for sure supposed to be a 500 never cranked. Same owner since 1987. So 2 owner truck. 12speed mack. Supposed to be all Mack bumper to bumper. Neway air ride. 60” bunk, red interior and it is still roadworthy. Only drawback it’s an aluminum frame. I am guessing from the cab back. What concerns would you guys have with the frame ? If I am correct worst case is replacing rails from cab back. I have never had or driven a truck with an aluminum frame. The engine I am guessing should have the inline p pump. Also pm’s are welcome. Thanks and have a great day. 3 Quote Link to comment Share on other sites More sharing options...

mechohaulic Posted December 4, 2023 Share Posted December 4, 2023 why would it be alum from cab back ? don't recall combo rails. alum (westerns) were alum front to back 🙄. maybe changes came after the '70's Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted December 4, 2023 Share Posted December 4, 2023 after the 70's they were aluminum from behind the cab and back.. I think they were 7/16'' thick... I have only been around a few of them, certainly not a guru on these.. 1 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted December 4, 2023 Share Posted December 4, 2023 I'm going to take a stab at this..... right -or-wrong.. I believe they were RW 6-or-713 ST's.... 1 Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted December 4, 2023 Share Posted December 4, 2023 just proves the fact ;; never tooo old to learn . possibly why I wasn't aware of combo rails, also back in the day Mack westerns on the east coast were an extremely rare Dog. did prep for delivery a F-700 western having the 866 v-8 and alum rails = full front to back alum 1 Quote Link to comment Share on other sites More sharing options...

Popular Post 1961H67 Posted December 4, 2023 Popular Post Share Posted December 4, 2023 A friend of mine has a 80 W 900 KW , Factory KT600 , Aluminum Frame, it was bought new and used for heavy hauling around Charlotte NC , Frame is Perfect! On the other hand I have a 1987 Freedom Superliner with Aluminum Frame, it bolts to steel under the cab , It’s very corroded anywhere it bolts to steel . It came from Ohio . Both Aluminum Frames are the same thickness, so just my opinion , Salt and bad weather would be much worse for Aluminum than Heavy loads, if it looks good and isn’t corroded I wouldn’t worry about it. 4 Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted December 5, 2023 Share Posted December 5, 2023 a '79 RL600L on craigslist has a number of pictures.one of which gives half/a-s picture of bottom side looking at transmission (RR13) ; point is based on this conversation, the alum rails look to go full forward. flanges definitely thicker , can't see the rail thickness. long wheel base tractor asking price $12K. 2 Quote Link to comment Share on other sites More sharing options...

Popular Post Vladislav Posted December 7, 2023 Popular Post Share Posted December 7, 2023 Western aluminium frames for RL600/700 were solid straight channels front to rear. Western Superliner and Cruiseliner had front portion of the frame stamped of steel and it was bolted to the rear straight portion near rear engine mounts no matter the rear rails were steel or alu. 2nd generation Superliners and Ultraliners had fashioned front portion of the frame rails. If they're all steel the rails were solid just with that fashioned design over the engine bay. If alu the front portion was steel with all that "fashion" down to the front fuel tank brackets nearly and furthermore straight alu rails went all the way to the rear. I was very surprized (and dissappointed) when found out those were done that way. But that's what Mack made in the factory. 3 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment Share on other sites More sharing options...
D-Day Posted December 7, 2023 Share Posted December 7, 2023 I have repaired and replaced numerous aluminum frames most were KW and Peterbilt used as log trucks the extreme rough roads would brake the rails vertically near the cab the Mack rails I have only seen small horizontal cracks around the rear suspension other than scale or delaminating as some call the rot where it contacts the steel if its always been on the pavement its probably not a concern easy to check with a good light 2 Quote Link to comment Share on other sites More sharing options...
