I've gotta say these Anthems are growing on me slowly The US Pinnacle to me is the best looking Mack in the US line up today Paul

I tried doing that type of thing Vlad but the internet can be extremely slow and the whole process became bogged down so the Postimage account works well for me now Paul

If you cant hear anything at all, try turning the truck off once it is full of air and then rotating the knob Sounds like you have no air supply getting to the box for some reason But first things first, establish a full air charge with the truck, ie start and run till it has built up pressure Then stop the truck and try rotating the switch control on the gear stick It will not matter if it's in gear or not Rotate thru from left to right allowing a moment at each position Yoy should hear puffs of air going thru the gear stick control Paul

In the rear section of the box you have high split, low split and reverse The high-low split and reverse are mechanically interlocked, it sounds to me that these have bound up for some reason and I would do as Joey suggests Pull the lid and have a look This is a fare bit of stuffing about to do this but it can be done with out dropping the box out If its a air ride cab stick a jack under the cab between the chassis rail and the cab floor and jack it up as high is it will go without damaging anything With the floor out and the cab up you can get it out okay, getting it back in and lined up right is the hard part But before you do all of this, can you hear the shifters going clunk etc as you rotate the knob ? The mechanical interlock is situated in the blue circled area, theres a nolt doo hicky were the arrow points were the mechanical interlock comes outfor working Paul

Not exactly the same, there is some degree of movement in the bolt holes, it is always best to spill time it as you have no idea if it was right before hand Paul

No matter were the leak is I think putting some pressure in the system is by far the quickest way to find a pesky leak Paul

A Thermodyne is a turbo engine as well, so perhaps put some engine numbers etc up and someone here can tell you what you have Sounds like some adventure ahead of you once you get some time to tackle them Paul

Thats a great result, did you put sound deading in before the interior was done Paul

Drop the box out, stand them om their ends and separate and replace the gaskets, biggest job is getting them out but well worth it it'sleaking this bad Paul

You have a leak in the return side of fuel system Pressurize the tank slightly to show the leak A hose clamp and a piece of old inner tube over the filler will show the leak pretty quickly Wind the air regulator on your shop compressor down as low as it will go, once the fuel system is at 10 or 15 psi have a look all around the fuel lines for the fuel leak Paul

And fix your oil leaks would save a fortune But yes, knowing how to operate them can make all the difference and if they dont then they cant really be blamed Paul

I believe that it should be master keyed so can only go in one way Once this is done it will need to spill timed, this is a two person job and you really need to find someone who has done this, not been smart or rude or any other such thing but it needs to be right I doubt even most heavy diesel mechanics know how to do this properly However your local diesel injection place probably can supply the second person and they can talk you thru it to and help you get it right I have done it before but I am not confident enough to be giving instructions here Paul

Is it the same box, as in casting ? If so can the gears on the counter shafts and main shaft be changed and made into a over drive Paul

A good result then Paul

so no body knows if a Mack box can be turned into a overdrive by swapping gears and still using the same housing ? Paul

I have beem asked another question Can a Mack direct be changed into a overdrive like a Roadranger ? I have never looked into this as I have never had a need This doesn't even look like a Mack number to me but I dunno It is definitely a Mack Maxitorque 12 speed with deep reduction on the dash Paul

Well done and hope it all works out for you, looks neat and tidy Paul

The photo posting can be one heck of a challenge at times but I feel it is worth it adds so much to the forum to have pictures and makes it more enjoyable for all Paul

Well the truck is pretty much what I expected A 350 with a series coolpower motor 12 speed, lite ass end 34 or 38's Has had broken banjo housing on the front diff My brother is looking at it, will see what comes of it, I'll chuck some more photos up after he makes his mind up I keep on reminding him (my brother) that the truck is nearly 40 years so everything will of been rebuilt several times over already and nothing most likely is still original Thanks for everyones input Paul

Thanks Rob, I'll pass the info on Paul

Well hot off the press The injector pump plate Can someone decipher these numbers etc for me please Thanks in advance Paul

Sorry no help here Paul

Sounds like something was in a filter some how that is almost blocking the gallery and pushes across with pressure as soon as you start it Dunno, pretty hard to guess much more with out been there, it will be most likely something silly Paul

Dunno were you live but most major cities should have a spring place that can roll you up a fresh leaf to suit I would of though Or just take a tape measure and wander around local truck wreckers to find something close enough Paul
