ndvaughn Posted April 26, 2016 Share Posted April 26, 2016 Quote Hi all, I bought a new to me 2000 Mack CH600. Seems extremely clean and runs very well. It only has 310,000 miles and a clean title. Owned by a guy who ran side dumps and end dumps. I guess its a little late since I already bought it but I just noticed the hour meter. Didn't give it a second thought cause none of our other trucks even have them. It's just over 20,000 hrs. Seems a little high to me for the miles, but like I said it doesn't leak at all and seems to run very well. Although haven't had a lot of time to run it a lot yet. Anything opinions? Also, I see everyone talking about oil analysis, how does one get started? I've wanted to do it but have never done it for any of our trucks or tractors. Usually just go with the 10,000 miles on the trucks and 250 hrs for tractors. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/44987-20000-hrs-and-310000-miles/ Share on other sites More sharing options...
General Ike Posted April 26, 2016 Share Posted April 26, 2016 While I know that this doesn't account for idle time.... but if you're doing 60mph your doing a mile a minute. 20,000hrs times 60 minutes in in hour = 1,200,000 minutes or 1.2 million miles. So unless this thing sat for many hours every day idling, I'd say there is a discrepancy between your engine hours and your mileage.

TeamsterGrrrl Posted April 27, 2016 Share Posted April 27, 2016 For trucks that live in city traffic or have a lot of PTO time, a 20 MPH or less average ain't unusual.

AZB755V8 Posted April 27, 2016 Share Posted April 27, 2016 There should be some maintenance records on that truck somewhere. Check the original dealer it came from. Even if it was owner fleet maintained they would have records. Just ask the seller for the record for your reference and maintenance cost, shouldn't be a problem...Right. If I remember right I bought a 93 CL700 with 17,000 hours and 390,000 miles. It was a local oil field truck and didn't seem too far out of line. I know the Speedo was correct from the records, avg 23 miles per hour. Ran good the great oil pressure.

Ahubbard Posted April 27, 2016 Share Posted April 27, 2016 My dump before I changed the motor was approximately 18000 hours and 340,000 miles. It's a 99.

ndvaughn Posted April 27, 2016 Author Share Posted April 27, 2016 So what I'm getting is the fact that it is high hours but not necessarily out of line for a dump/vocational truck. I'll try and get some maintenance records from the previous owner and or the original dealership if possible. 20,000 hrs does spook me a little but I guess that's because I'm used to the hours on our tractors which are all under 8000.

Need to run them a little more.... or at least idle them...

bbigrig Posted April 27, 2016 Share Posted April 27, 2016 The mile and hours match up for a fleet I used to work at hauling cement in bulk tanks. Pulling loads added miles. Blowing loads into silo's added hours. Seems legit for that type of use.

Mack Technician Posted June 6, 2016 Share Posted June 6, 2016 If your counting on it for West-to-East coast take it in and have a Manometer test run on it. Then start checking oil for metal and coolant if it is a 400-460 horse. That can be your peace of mind. If it is a day cab truck test oil and forget the hour meter.

Brian Blaylock Posted June 6, 2016 Share Posted June 6, 2016 (edited) I am currently driving a 2013 with 8868.8 hours and 120704.6 miles both are correct I use pto pump to load and unload both hrs and miles multiplied by three gets in the ballpark with your truck Edited June 6, 2016 by Brian Blaylock Quote Link to comment https://www.bigmacktrucks.com/topic/44987-20000-hrs-and-310000-miles/#findComment-335732 Share on other sites More sharing options...
