GB26JJ Posted August 14, 2022 Share Posted August 14, 2022 I have a 2006 Mack CV713 tandem-axle dump truck with an "E7 427" engine and a 13-speed Eaton Fuller manual transmission (not sure of other exacts). I'm trying to locate a diagram or video with basic, user-level walk-around information. I'm not even sure where to check (or fill) the transmission fluid! Also, I know the PTO is leaking...is that hydraulic fluid? It's mounted directly to the side of the transmission. I'd like to be able to check whatever fluid that is that's dripping, and add as appropriate until I can get a legitimate fix. Finally, I have a small leak from the rear portion of the drive shaft (right before the front set of duals). Is this differential fluid back there? Again, where do I check said levels and add as appropriate? Quote Link to comment https://www.bigmacktrucks.com/topic/70279-rookie-needs-help/ Share on other sites More sharing options...

mrsmackpaul Posted August 15, 2022 Share Posted August 15, 2022 Second photo Looks to me like the input seal on the power divider is leaking It has three oil levels on the front drive axle, one on the power divider, one on the top half of the diff and Im pretty sure the other will be on the real of lower section of the diff housing You can see the first two in photo, they will have a square head on the bung, fill up until it runs out I reckon the PTO will have a crook o ring, and no it is gear oil, the hydraulics are dirty half to the right of the picture 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70279-rookie-needs-help/#findComment-506388 Share on other sites More sharing options...

GB26JJ Posted August 16, 2022 Author Share Posted August 16, 2022 Is there an easy way to get a hold of an owners manual, or the equivalent of one, for a truck this old?

Joey Mack Posted August 16, 2022 Share Posted August 16, 2022 I would say that the best book you can get right now is the "Maintenance and Lubrication" book.. for your year; the book number is: TS-49406.. If you find this book, will you please let us know? that will help others who are looking as well... jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70279-rookie-needs-help/#findComment-506524 Share on other sites More sharing options...
