Offroadingrlife Posted December 26, 2020 Share Posted December 26, 2020 How hard is it to get parts for trucks that are over 20 years old now? I’m looking at buying a 99 rd688 dump truck amd want to make sure when I need to get parts it’s something I’ll be able to get. the other question I have is what is the lodge expectancy of a 99 with a e7? One I’m looking at has a little over 450K miles on it thanks Quote Link to comment https://www.bigmacktrucks.com/topic/65381-parts-availability-for-older-trucks/ Share on other sites More sharing options...
alex g Posted December 26, 2020 Share Posted December 26, 2020 You've come to the right place for parts and advice. You should have no problem finding parts for a 99 and depending on how it was taken care of it'll go a million or better 1 Quote Link to comment https://www.bigmacktrucks.com/topic/65381-parts-availability-for-older-trucks/#findComment-466175 Share on other sites More sharing options...
EastTex Cartage Posted January 1, 2021 Share Posted January 1, 2021 Mack R series kinda wrote the book on vocational trucks. The E7 was designed as a low RPM engine. They are not race cars. They will haul dirt/sand/aggregate/whatever through things other dumps just will not. Most R series do not have a 'diff-lock' per say, but they have a centrifugally activated 'peanut' setup that really works. They will last forever. I also have an International, which started life as a dump and the rear diff housing has been welded many times. Asking the rearend guy why? He replies 'It's not a Mack' Quote Link to comment https://www.bigmacktrucks.com/topic/65381-parts-availability-for-older-trucks/#findComment-466392 Share on other sites More sharing options...

That’s for sure! It’s a 2 owner truck. Looks to be in good shape for its age, I do know it’s 20 years old, and has almost half a mil on it. And it’s been used to haul asphalt it’s whole life, but for me to just start out in the industry I think it’ll work alright, miles do scare me a bit though Quote Link to comment https://www.bigmacktrucks.com/topic/65381-parts-availability-for-older-trucks/#findComment-466502 Share on other sites More sharing options...

Popular Post Joey Mack Posted January 3, 2021 Popular Post Share Posted January 3, 2021 I just built a '90 E-7 Mechanical this summer. All of the parts were available through Mack, We chose P.A.I. parts. The quality looked great, and the price was less than half...You should have no problem getting parts for you're truck. You got a Great one there. The R/RD set the bar very high, too high for some non-Mack trucks.... When I get a new customer and i see an R/RD or a CH, -or- CL.... I smile because I know, "I Got This!".. I wish you well with you're new truck. Like Alexg said..

How reliable are the older trucks with higher mileage though? I was talking with the dispatcher for one of the local asphalt company’s and he said they don’t have age limits on trucks but don’t want you to be breaking down with a load of hot mix in the bed. That statement has me a bit worried with the amount of miles I know anything is questionable Quote Link to comment https://www.bigmacktrucks.com/topic/65381-parts-availability-for-older-trucks/#findComment-466610 Share on other sites More sharing options...
Popular Post Joey Mack Posted January 5, 2021 Popular Post Share Posted January 5, 2021 Sir, Thats what : Pre-Trip inspections, Regular maintainance, and giving a damn, are for... If you have employee's, I hope they "Give a damn" Yes older trucks, ,,,,,,Hell.... any machine can break. But when your '99 RD has an issue less than the Engine, or drive line... It wont be 10-20K to fix it, and a guy like me, can get you back to work quickly... Just a thought......Jojo.... 3 1 Quote Link to comment https://www.bigmacktrucks.com/topic/65381-parts-availability-for-older-trucks/#findComment-466614 Share on other sites More sharing options...
Mark T Posted January 6, 2021 Share Posted January 6, 2021 Nevermind the miles, how many hours are on it ? Old truck up over 20000 hours ? If nothing was ever done to it, it's at the point anything could happen....and that includes rub'n like a Swiss watch a while longer. Personally, I don't think there's a black or white answer to your question.

storkmack Posted January 6, 2021 Share Posted January 6, 2021 (edited) I don’t think we have a mixer with less than 20K hrs on it. All E7’s. We try to run them a season, then do rod and main bearings and an oil pump. Then run the dick off of them.

Mark T Posted January 6, 2021 Share Posted January 6, 2021 That's my point, they run indefinitely if taken care of and little stuff doesn't snowball. But without being familiar with the trucks history ?

storkmack Posted January 6, 2021 Share Posted January 6, 2021 Dad had a 97’ CH he bought new. 400 and a Mack 13 sp. one of the best damn trucks we ever owned. When we got rid of it it had 1.5 mil miles and 47000 hrs. If it was a dog, you would have taken it out back and shot it ,then cried. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/65381-parts-availability-for-older-trucks/#findComment-466623 Share on other sites More sharing options...
Joey Mack Posted January 6, 2021 Share Posted January 6, 2021 I drove one of those too, it was an 18 speed, however it out pulled a lot of non-Macks. I pulled a tri axle framed dump trailer, and we were loaded heavy... and this truck got it done, on and off the road... If I went back to owning another one... I would look for one like it, anyway.. This era of Macks were TOUGH..

I was talking to someone locally and they said to watch out for the frame separating? Not sure what he meant?

alex g Posted January 6, 2021 Share Posted January 6, 2021 The frame will spread where it is double framed. Its called rust jacking. Quote Link to comment https://www.bigmacktrucks.com/topic/65381-parts-availability-for-older-trucks/#findComment-466652 Share on other sites More sharing options...

How can I tell if this is happening? The truck I’m looking at is from the rust belt, although the frame has very little rust on it.

alex g Posted January 6, 2021 Share Posted January 6, 2021 Crawl underneath and look at edges of frame where it's double framed or any place where it's bolted together like crossmembers. It's a older truck and being from rust belt there's no doubt there's some rust jacking. There are limits to how much spread in frame for safeties so you'll want to check this out. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/65381-parts-availability-for-older-trucks/#findComment-466654 Share on other sites More sharing options...

I haven’t went to look at the truck, it’s about 10 hours away from me. I need to gather as much as I can before I go to look at it.

alex g Posted January 7, 2021 Share Posted January 7, 2021 Yup there's your frame spread I've seen worse but unfortunately it doesn't go away it just gets worse. I'd show that to whoever you plan on getting a safety from and get there opinion. 10 hours is quite a journey any reason why your going that far I'm sure you could find something alot closer 1 Quote Link to comment https://www.bigmacktrucks.com/topic/65381-parts-availability-for-older-trucks/#findComment-466672 Share on other sites More sharing options...

I’ll travel if it’s worth it you know, but if it’s not worth it I wont. I guess I should look for a few more trucks to have a backup plan Quote Link to comment https://www.bigmacktrucks.com/topic/65381-parts-availability-for-older-trucks/#findComment-466673 Share on other sites More sharing options...
Offroadingrlife Posted January 9, 2021 Author Share Posted January 9, 2021 So I ended up passing on the truck. I’ve been looking at TruckPaper non stop trying to find some other ones that fit what I’m looking for, issue is everything in my price range has high miles. I’m hoping to find something soon Quote Link to comment https://www.bigmacktrucks.com/topic/65381-parts-availability-for-older-trucks/#findComment-466741 Share on other sites More sharing options...
Offroadingrlife Posted January 11, 2021 Author Share Posted January 11, 2021 I have a friend who sent me an ad for a truck he found. It’s a 99 688s, has 800k on it, motor hasn’t been touched besides normal pms, it was running everyday up until end of asphalt season. The price seems like it’s a good deal but again miles concerns me. I need something that’ll make it through the season without breaking down every week. This ones about 5-6 hours away. What do you’ll think? If it’s cheap enough buy it and put money aside for when it breaks? Ideally would like to be able to get a new truck in a year or 2 and then have this as a spare Quote Link to comment https://www.bigmacktrucks.com/topic/65381-parts-availability-for-older-trucks/#findComment-466829 Share on other sites More sharing options...
alex g Posted January 11, 2021 Share Posted January 11, 2021 Unfortunately there are no guarantees to wether it will break down or not.
