Thank you very much sir I appreciate your response, I will check the gauge then because when the air tanks are drained the primary gauge stays at around 15 20 psi and the secondary completely drains to 0 psi

How you all doing gentlemen,

I have a 2006 mack granite cv713 

And primary air pressure is going up to 140 psi and secondary is at the right pressure I already changed the governor but it didn't get it fixed does anyone have an idea what could be it, thanks in advance 

Hey guys I hope you all doing ok, I'm trying to replace my truck's rear seal but I don't know the size of the socket to take out the axle nut and there's is a nut with two Allen keys screws can you guy's please tell me the procedure like the torque for the axle nut thanks in advance 

Thank you everyone for your help, yes Joeh is kind of a solid stuff it is sitting at the bottom of the coolant reservoir

Joey Mack yes sir, I think those hoses hasn't been replaced before they look old, that has to be the issue, you all are always very helpful thank you very much Joey 

Hello everyone, I hope everybody is doing ok, I have a question about the coolant in my mack cv713, there's is a black stuff in my coolant reservoir do you guys have any idea of could of been the issue?  Thanks in advance. 

Lol

Yeah you right fjh thanks 🙂

I'm a bit confused now, I forgot to tell you guys that yesterday when I got the pump at the dealer one of the mechanics told me why I was charging the pump I told hin because it was leaking fuel, and he told that those are almost impossible to leak what guys think about it?

Ok thank you Joey, good night. 

Or I just have to bolted will it align by it self? 

By seathing the pump do I need to do any procedure in order for the gear to seat right? 

Yeah our trucks need some love too jajaja we need to give some of what they provide to us

Yes I came to the right places you guys are great I greatly appreciate everyone's help I'll be in touch and keep updating be safe you all good rest of the day thanks

And then it was leaking pieces of gears

Lol

Lol 

No unfortunately I couldn't take a picture or video but it's was dripping and when it run out of fuel it started  spraying fuel vapor

 I just did the pressure test on the suply pump and yes is leaking fuel from the shaft

Or it could be the galley plug?

Guys I took the suply pump off it looks like the oil has been wash off, do you guys think that's what is wrong 

Ok thank you Joey I will test it get back to you guys 

Ok thank you joey mack I will buy one of those books right now, so to check the eups I use the back of the engine plug and to test the lift pump I use the bottom plug near the timing cover or the breather 

Ok thank you for the information mrsmackpaul I will buy one
