0 Onyx610 Posted March 5, 2022 Share Posted March 5, 2022 Great engines, In cylinder egr on that engine. Nothing to worry about. The “AC” engine is the problematic one, with the egr cooler and variable geometry turbo. 1 Quote Link to comment Share on other sites More sharing options...

0 Joey Mack Posted March 5, 2022 Share Posted March 5, 2022 The Granite truck is a good one, It replaced the RD. The ASET I is way better thatn the 'C' series.. Do you know how to tell the difference by looking at the engine? Good luck, jojo 1 Quote Link to comment Share on other sites More sharing options...
0 Firefox898 Posted March 5, 2022 Author Share Posted March 5, 2022 No I’m pretty green when it comes to visual differences(the 86 Mack is really all I’ve known for the past few decades) Quote Link to comment Share on other sites More sharing options...

The liner is a little spread in the one picture, but nothing serious. That truck does look pretty clean and looks to have been used right and taken care of. Even with the shortcomings of an AMI ?? for the miles you're talking about putting on it and the general condition from the pictures ? Looks like it should definitely be on the short list of trucks to replace the older one Quote Link to comment Share on other sites More sharing options...

Looks like it should definitely be on the short list of trucks to replace the older one i was thinking along the same lines as you...im just unsure/uneducated enough on whether the AMI is as bad as some of the things people say about it... Im almost positive i will notice a difference in power compared to what i am driving now(especially going up hills fully loaded which is miserable) Quote Link to comment Share on other sites More sharing options...
0 Mark T Posted March 5, 2022 Share Posted March 5, 2022 AMIs aren't exactly good runners (lol) and they can be a problem as they get older. This one seems (to me at least) to be relatively low miles/hours and the truck looks clean and cared for. If you use it like your post suggests , I'd think you'll find worse trucks to pick. By 58,000 I'm assuming you mean gross weight ? There's lots of life left in that truck in the pictures from what I can see. Those engines were internal EGR and in my opinion require an oil change way more often than the book that comes with one said. They have a fickle overhead, but as long as it's been maintained (updates and in adjustment) they have a fairly long serviceable life. Lots of guys complained about them cause they didn't set any records for throttle response. Again, in your situation ? maybe it's more about if the truck is what you need for the job and if the crane is in good working order .

Yes 58000 fully loaded..roughly carrying 19000 in weight regularly.. I fully intend to do what is necessary in terms of maintenance to keep it running for as long as possible…and I have to assume it’ll be a different driving experience than what I’m in now..appreciate the info!

0 Joey Mack Posted March 7, 2022 Share Posted March 7, 2022 I would rather have that one, over the other option for that year, and there after.. Best of luck to you.. Jojo Quote Link to comment Share on other sites More sharing options...
0 Mark T Posted March 8, 2022 Share Posted March 8, 2022 Somebody did a pretty nice job cleaning that up and painting the frame. Personally, I see a few things that tell me it wasn't a basket case before the detail job. That's a pretty nice used truck I'd say. 1 Quote Link to comment Share on other sites More sharing options...

Centrimax still has a Mack sticker on it. Def don’t see trucks like that here in PA.

It's none the less a really clean used truck . It does certainly seem to be in pretty good shape, let alone for the age of it. Nice Granite.
