Can you guys still find the shock fluid that goes in the rota shocks? glenn

Yes it is nice to run in to a place like that i know a place that i have used for years that is not a dealer but independent rebuilder of gears and used to be of enginesd but i have used them many times and always they at the counter are trying to find out if you are forgetting somthing and will stand there and eat up there time trying to locate a part some were out of the network just so you will remenber them. I have hear some guys complain about there gears and rebuilt units and i have tryed i guess in evey case help with there trouble shooting their problem and most cases find out that some one on the radio on the road or like that was the one who told them what to replace. In other words a lot of times you have the guy that works on his own truck but dont know what is wrong with it and then things dont go like they want and then that is were the parts man gets blamed. I love to spend my money with some one who shows some interest in me and not mad at me for showing up at his counter. glenn

Its trying to say replace me but you can replace the valves in the head with a field repair kit that i am sure bendix still sells. That will be a tuflow 500 bendix and you may be able to replace the maintenance kit with out pulling the compressor. You have done your home work to find were it was leaking. Some guys would have never found that. glenn

Wait till you retire and dont got much money and then my wife always says you remenber all the money you sent in those old trucks and airplanes and non of them made you any money and i have to agree. I remenber what my mon all ways said about a fool and hims money and now i know who you was speaking of. me

If you have cracked a fuel injector line then you will not be able to pump fuel from it with the primer pump because unlike cat engine there is a delivery check valve in the bunnet. So when the injection pump is returning fuel to the tank like rob said you can crack some lines at the injectors and help some but in most cases that is not need if the injection pump is returning fuel to the tank. Also if those primers act tired thru it away and get a new one. The new one will be smaller and cheaper but will work. glenn

Rob on that trans you can put rear end grease like 85/90 mutigear or all purpose in it I am sure that mack has a new grease they ask for now but for many years the mack book said 85/90. mI have used in in a mack gears for many years. Eaton or road ranger dont use that. glenn

Tulsa auto spring still does it and i know of then for 43 years. They have gone to the cold rearch. I have had many spring jobs done their in fact i was out there about 3 months ago. So many times on old springs when you tear down a dip them then take a look they are full of cracks and Allen the shop man said what i agree with that if one has good springs but just want to add one and raise your ok but for one that has 800000 mile on it and is sitting low your may find too many leafs cracked.

I am sorry for getting into this i had no intent to confuse. glenn

if you use a non mack axle you will have to redrill the spring u bolt hole in the spring pads on the axle becausbecause moisture will ruin a air set up.e mack uses a wider springf spacing from any one else.That is not DOT aproved also but OHwell.I used a air /asiste For a trans star 11. works well on a light front end like a B61. The next time you change your air compressor trade out for the bigger one and get a air dier on it. glenn

Rick Harper her on the board may know were some photos may be so i would say send him a message. glenn

Cant you go one day with out cornbread. I do and get by but it ant the same i know. glenn

I can help you some and he may want to add some but a END can be many engines but it could be a ENDT but the END was a different engine than a ENDT673b or c .The B and C was different engine but same look alike but was same block crank and rods and head as a 237 maxidyne.It had piston oil coolers and larger rods with more head bolts and larger injection pump. It had a different rear oil seal and i think when to the maxidyne liners after it was a year old. The older END and ENDT did not have piston coolers and was using a little different head and smaller wrist pins than t6he maxidyne. The B and C was rated at 225 and 250 horse were the old ENDT 673 was rated at 205 hore. glenn

That6 is the over drive gear and it will have a bushing in nther o/d gear on the main shaft. The bushing is worn out and letting the gear ride too far away or too close to the counter shaft gear. Went i worked on macks years ago there was a bushing that could be put in there with some machine worh but if it has been doing it long it will need a gear. The counter shaft has brgs on it but if it was bad it would have a noise in low split also. This this problem could be the rear out put brgt but i dought it. The rear box can be removed with out pulling front box. This some times happens when a trans has been run in O/D too much at low RPM. glenn

The brand name does not mean any thing any more for as who built it. The wagnor corp will sell their name any time for a profit. That is somthing i thing is going on ever were. Made in US does not mean genuine. When i was still trucking i picked up a load of shirts and jeans made in china and was off loaded from a ship container onto my trailer. It went to a wrangler plant in ok. I was told that the garmints was complete all but one button hole and a button. That is a way of not having to pay a tax on finished products into the US.Wrangler plant finishes the product and puts in their box and that is how it is done in many cases. glenn

Yes you can but just dont set the fuel out on it much if any and this will get rid of some smoke and burns some less fuel. glenn

Sounds like your said that if banks are left along they will go out of busness but when they come back they will do better the next time. Well i agree with that. If i had a corp. that failed i would not learn any thing if you guys come down here and put me back in busness. That would not be fair me or you. I keep reading in the Bible about end times do you think there is something to that and what will it look like and how many of us will see it and how will it have to come around. This problem is not just the US but the world. glenn

Ya that is what i was trying to say. Alot of smoke if you could get it out of the pipes. Then it probley would spit a gasket out from under the heads. glenn

It will bolt up and start but the calibrations are different. The 707 injector would have to have the # checked against the maxidyn engine and the 707 or same as 711 has a sncrovance in the pump drive to advavce the timing as much as 13 degrees at hi idle were the maxidlyn pump has a direct drive and has no advance and on top of that the 707 has smaller pumps and will not fuel as much and the maxidyn pumpThe maxidyn pump has a different governor for low end torque so the pump would be of no use to you. The 237 pump would destroy the 707 engine if you put it on. The 707 engine has no turbo and is not a low end torque engine and could not be used for that because of other things. glenn

Now that is my line do somthing about the fuel price but i guess it will take care of it self as soon as this oil gets to 25 dollars a barrel. It would be funny to here the arabs begging for some one to buy their oil. But when nobody has any money who will buy it? glenn

Try taking out the snap/ring in the bottom of the new foot valve and remove the spool and see if you dont have some rust or tefon tape under the rubber seal and see if that dont repair. If there is only one supply and one deliver to that foot valve and it has air coming from the exhaust it means your spool is leaking in the foot valve. glenn

Thad is right the valve is working backward. Emergency means you want to stop the trailer so it cuts the air and sets the trailer brakes. Try takeing the plate off and turning it up side down but then you are going to stand on your head to read the label.

Rob on a E7 engine and i am talking about the late vmack and the Etec the problem with setting up the HP is you start to move the liners around on top of the counter bores and that is what makes the counter bores drop in height or fret and then when you are trucking down the road doing good your liners are losing liner protrution and now you start to blow head gaskets and if the counter bore is not restored back then head gaskets keep on blowing. The E6 had a good life in them as long as they were not pump up on fuel. What would happen on them they have a small bottom end and after alot of miles the line bore gets twisted and the crank is in a bind and can break a crank or sping a main brg. The hi torque low rpm engines do that offten. The problem with setting the fuel up on a mack engine and it being a low rpm engine to is it will make more torque at low rpm than it is made to do and the block can bend at the bottom and that is what pulls the line bore off center. Some dont know this but you can put a line bore test bar which most guys dont have but it is to check line bore on a stripped block with caps in place and torqued and you can put the test bar in the block and check the alinement and find the problems . But if you find one that is good you can take your hand and bend the block and lock the test bar while you have pressure on it. The blocks are pliable to a certain amount.But when you start to pull a lot of torque thru the engine then the block begines to bend oppsite to the way the crank turns. I have started to put main brgs in and found that they will not go back in the top because there is not enough clearance to get in with out locking the crank. This happens over a alot of miles not over night so that is the reason play trucks can blow smoke and burn rubber with out a lot of troubles. But i have had drivers come to me because i have worked the fuel systems for a long time want there engtine set up as soon as they got the truck ready to hit the road. Not giving it a chance to show him what it can do. I have been a o/o two times in my working days and that made up of about 220000 mile and ever time you run west you will see one truck that has to be in front and if you listen long enough you will hear that he has his fuel set up and as he says come on and try me. The first time i was on the road i was flat beding for 14 months before i went back to the shop and i had a NTC 365 and it is easy to get more HP out of it but iset it 15 psi over specs and it did help some but on the pa turnpike with a gross of 80000 i would pull down to 45 mph on some hills but i did not have to worry about what i know could happen to my engine not from that pull but from the years of abuse before that that could happen to me today. I could be on time but did not get to stop as much. Its like they say you have to inside of your truck to get there.

I am not here to say you cant do that or the engine you had did not do that because i way not there. But i can tell you that i have seen for years a patteren how the engine go down when juised up and it is not the engine to be blamed. I have seen drivers that can take care of them and when they are paying the bill that helps but i have seen it happen so many times were the driver has set it up and it cut the life. The engine manufactors meaures the life of a engine from the lbs of fuel it burns in its life not by the miles. If you can get more HP with the same or less fuel then you can get rich by showing the builders of engines how to market more HP on less fuel. If that dont work then train drtiver to drive and get more HP with less fuel. I have run a truck some for my self on the road and i know you may help fuel mileage some by setting the fuel up some but you have to get out of it at some point or it will burn more fuel. May not that much to get more hp if you need it but it will still shorten the life of a engine. I have been around fleets enough to know that they spec low HP for a dollar reason. Not for any ones safty. Longer life and less fuel burn. I see if you are a heavy haul you can justifi the change of a earl engine failure because you need it. But like a dry box operation or a dump truck needing 500 hp is not a money making move. It is fun tho to be able to be in front on a long hard pull. Me and my self have seen too many truckers have to walk away from a truck and leve it because they dont got the money to bail it out with and i dont want to be in that postion so i had to take care of my truck when it was on the road. I had a 470 DD and with 80000 i could stay with the ISX 600 the co had untill we go in the mountains. I tryed to run 70 mph because our loads was in most cases late when we got them. The ISX was better on fuel and they were open up on speed. What is shocking is when one of the E7 breaks a piston for no nreason and breaks a block. If under waranty that helps but i have never had a new mack and will never be able to own one. I am not down on a mack because i started working on macks when the B model was in the last two years of production so i love a mack . I have a B61 my self that i hyave a 320 horse in it and it is set hot on top of that but it was only a play truck and never stood in it very long or it could burn. glenn

All you guys are asking for is to get to overhaul your engine before it is time to overhaul. The deals you are using is only shorten the life of your engine. saw it many times. If you had enough gauges like a pryometer and boost you may run some longer but most people will mash on their motor not relizing that it is over fueling and bumping the timing up and that increases the exhaust heat and it increases the cylinder pressures. The first sign of trouble is excessive blow by and then you will find it smokes more on start up from weak compression and then oil consumpion is next or a burnt piston.I have set HP up as much as any one ever will in my younger days but now with engines costing up to 16000.00 for a inframe with a dropped valve and bad turbo i cant see that it is worth it. If one is low on power i think the problen needs repaired and then think about a mack engine. It is not a big cube engine to start with but puts out more HP than most other engines that size so that means they are on the edge of destuction any way. I have alot of respect for a small cube engine that works like it does never complains about what you do to it. My 2 cents and 40 years of working on engines glenn

Dont forget that the new valve can have some dirt or rust or telfon tape under the spool in the new valve. So many times rust from a air line that is in bad shape or rust from the air tank can get in the old valve make it leak as well as the new valve. glenn
