They did it slow but with the help of a double reduction rear end and low ratio on top of that.I remenber them very well working here in the oil field. Also were i worked at the old deal ship was years ago was a steep hill and i have seen trucks with cummins pulling big over size loads give it up to one old B model mack to take it over the top.He had low gears and started in them.

You was adjusting the satic timing and that is i think a 315 HPA very good engine in its time.

When that trans was around i know a few guys that had them and i have worked on them and drove them some.If the driver is used to trhem thay shift with out grinding but only thing drivers didnt like was having to cltch on ever shift. Also check the grease and it should have a light weight grease. If its got gear end grease it will not last because it has neeedle brgs and the heavy grease would also make it harder to shift.Make sure the air pressure is up on it.

I guess you are using the clutch to shift the rear box ant you?

Also you may check for a draw on the battiers.

But later it came out that the one she killed was a boy freind so firgue that out.

He may not got no panties on today.Some juys dont you know. some guy at work ever few weeks tells us on the radio he dont got his on.

Try this Rob

My truck has dayton on rear and i had one side that would not keep from slipping. The tire shop changed all of themand maybe a year later i got them off and compared them to the one that comes from mack and very little difference but enough to mack a difference.no more prblem after maybe buying two sets.

I can not figure out what any one needs him for.

What is a LL 16 speed?

Sounds like a good engine to me.

Rob Glad you found it. I had a hose to break with me last week on the job. Load of agbase and going down in a hole were a new build is to be and two you spanich speack kids give me a tour thru the mud and then a hard left turn as my steer bogs down. They were told to make the drivers hurry and as is was trying to turn a power steering hose broke. #15 tires on front and loaded you ant going to turn in the mud. Thye was in a faint mode. then thejust routed the other trucks around thru another gate. Yes was wandering why i was routed thru the mud any way my sons job 20 sent a guy down and with only 1 hr of down time was back with it.

make you a tee from a swivel and put it inline of the supply line to the injection pump after the sec filter that was it will fee what presssure the galley of the injection pump sees.This will check for flow pass the two filters and supply pump. If the pressure ant there then the flow want be as well.Lowflow will be from air,a restriction, stopped filter and also bad supply pump. this is done also when the pressure there is not enough and use the visegrips on the return line and this will test your supply pump if the pressure is low in the begining. The supply pump when the return is pinched of can run up to 70 psi.But the regulator or over flow valve is set to maybe 32 psi for the galley pressure. A plactic line clamped to a couple of # 6 swivels works good inline to and after the supply pump to see if there is bubbles and were from. Also when you have a miss on mack engine it can be from a broken deleiver valve in the bonnets inside of the injection pump. This can let a injector line bleed down between strokes and is found with a loosing of the injector line with air bubbles in the return line to the tank be cause the injector does not 100 % check all compression from the cylinder from reintering the injection pump. glenn

It would be a good time to send the heads out to be magfluxed and pressure tested.Some times the head can crack from injector bore over to valve seat into the coolant .

Your on the right track about getting away from the maxidyn tuning .It is a mess to drive a maxidyne with a 10 speed.

Rob i would before i did any thing make you a tee to go in line of the supply line frome filter to injection pump and connect a 50 psi gauge to it. I have one i built almost 46 years ago and you have to have one to trouble shoot a mack fuel system. connect to a gauge and long hose and tie it to wiper arm and test prssure at full load. My tee was a # 6 swivel brased to a male brss # 6 fitting and a # 4 taped into the side for the hose.Sounds to me your sucking air. And you need a clear plactic line to go inline to or after trhe transfere pump to check for bubbles.The checking of fuel pressure will show you a few things but if you dont have enough pressure setting in the shop running then with visegrips pinch the return line to the tank and if the pressure comes up the the fuel over flow or regulator valve is not holding the pressure up. But if the pressure does not come up after pinching the return then look for air or a restriction like a flapper in the hose. If non found then work on the transfere pump.

Even i can understand that.

The cat dealer he has one with a dump bed on it. I told the guys i work with it was a IHC cab so they go test drive it and the salsman says no it ant a IHC cab.

I would like to read a book written by Obama and see if he was this way from a child or if he sold his self in later years for maney.

Or do the water bottle test on the coolant side. Sinple and it will tell you if your getting compression into the coolant and if you are losing water due to a head gasket your getting pressure into the coolant. The compression is what starts the coolant seals to leak in the gasket. Get a pop bottle and fill half full of water then stick the rad over flow hose from the rad filler neck into the bottle. Warm engine as warm as you can get maybe for half hour then watch for bubbles. If so then it will be conmprssion from ahead gasket or crackd head or a air compressor which is rare.Also when the engine cools off stick your finger up in the blow by tubr from the valve cover looking for water dropples. If you find water there and no compression in rad then pull pan and prssure looking for a crack some were of a freeze plug leaking in the heads under the valve covers. glenn

same as all of them.

#6 valve over lap is spotting # 1 cylinder to fire or to time or to bolt pump on. # 1 cyl is the front cylinder. The rear would be 6. glenn

No i did not say the rear was # 1. Reread my post. Also the cover on the bottom does not show the timing marks. The timing marks do not have a cover.There is small opening with a small pin sticking out or a tab if its not knocked off.
