Be carefull with pressure on a tank that is not designed for pressure.

yes

It may have been a inspectors car. That's the way they are around here in city.You ask them to move so you can get in to dump and they go around the block and park in some elses way. White pickups I don't like.What burns me is some times you will deliver 5 loads and they have not moved their head one time and makes me want and ask if their are dead or just sleeping.

I think you can go to jake brake .com and look at the install manual for that model and get what you need.

When I have sand freze in the box and its not that cold here but I raise it and let the sun shin on the underside and it comes out quicker.On my box all I have had to freze is up front around the dog hose and on the floor.And that can happen in half hr.

And sometimes the engine mounts are bad.

The soot is not designed by the engine co to be put in the oil.It gets in the oil from excess exhaust pressure on the turbo and valve guilds as well as pass the rings.The turbo has more drive pressure on the manifold side than the non egr valve engine had so much more blow by now.

If your talking about the insulators on a 97 year, mack can be a good source for parts.

Larry your will also if you give it enough fuel but who wants to burn one. In the early days when I first started the old timers had their fuel set out enough to get a six" yellow cone out of the stack and most said that is enough to burn pistons if you stay in it too long.The timing has something to do with it also.If the timing is slow the fuel burns closter to the end of the power strok and some will go out the valves if slow enough.Fast timing or early timimg will burn deeper in the hole causing no flame but heat in the piston and coolant.

What he said. So get the ecm read and you will find some codes.

most hi/lift will lift normal or will lift at another point with air cyl which lifts higher than normal so spreding gravel is same as normal gate.

I have a 17ft round davis and with a hi/lift.It is so helpful to me even hauling asphalt.i like it cause I can lift it and check my bed or spray it down with out getting off of the ground.

Electric is wonderfull till it don't work.

Let mack connect to it and they can tell you what can be done.

236gb311a Same number as it was 45 years ago.

I think that is in inches instead of lbs per square in. But so its more than it should be why are you checking it?

Made in china and I had some of that.

The photo there of the mack dealer in Tulsa is were I started to work on trucks in that building in 1965.

Yes it will because I have did it.You will be so happy when its done.

You need to do some serious thinking and ask your self what am I doing letting this mechanic that I have now work on my truck. Another way of putting it is find some one else to work on it.

Here is the way we was testing them years ago. This would be a A circuit like most all large trucks used with a 50 amp gen. Make sure you have a good ground to the gen from the reg.If non then install and it don't need to be more than a 14 ga wire. Remove belt and jump from the batt to the arm ter on the reg and the gen should motor over. Then when its motoring ground the field ter at the regulator and this should slow down and almost stop the gen.That proves the gen will charge. No way to test the reg with out a tester but make sure first that the batt wire to the reg from the batt will carry current. Back in the day I would do a load test of 50 amps on that wire and the volts should stay about 12v with a load on it.

Don't try to use used parts.And if you do don't forget that you was told its not worth it.

That is the way I remember it.

He may have been helped his self like that once up on a time.I found years ago if you help some one it will come back to you but don't do that counting on it.

What did he just say?
