deep reduction can only be used in 1st gear there is a mechanical interlock to prevent it been used in any other gear when I go to split gears I find the truck is moving to slow to warrant splitting most gears 1st-4th for these changes to be worth while with most splitting is in traffic in the lower gears if I was to be running out of revs to low our to high I just give it a flick and and and off the gas and I have got another 400rpm either way the only thing to be awear of is that once you flick the range change there is pressure on the selector fork were as in road ranger there is only pressure when the gear stick passes through neutral so there is potential to put a lot of were on the selector fork on a Mack box I was always told if I am climbing a hill to change gears to match the hill ie if I can make it over by splitting a gear then just split the gear if I cant then wait a bit longer and drop a full gear but I think you could only do that with a Mack motor they seem to lug right down like no other motor Ive ever driven Paul

thanks Maddog Paul

depends on the tons your hauling this is me up to 42.5 tons 1 trailer start off with deep reduction in high 1st low split, 2nd gear low split, 3rd low, split 4th, 5th low split then flick it into high range up to 75 tons eg 2 trailers start off deep reduction in high range 1st low split, 2nd low split, 3rd low split , 3rd high and continue up splitting the gears up to 115 tons tripple road train start off with deep reduction in high range 1st low split ,2nd low split, 2nd high split then split all gears onward if I am am starting on a steep hill with big tonnage eg over 75 tons I might start off in deep reduction but you gotta be real careful as things can break real easy I have broken carrier bearing bolts pretty easy to smoke the drive tyres while waiting for the back trailer brakes to lift off all this depends on the road and the load dunno if this answers your question will be interesting see what other people say Paul

well Im still all a bit stunned by these hey Josh whats a baby quad a small quad box or the bogie ? this been educational thanks lads Paul

well Im no expert but this is quite common in farm tractors older ones before they all had cabs water always goes in through the gear sticks most farmers would cut a tennis ball in half and put half over each gear stick to keep the water out not that this is going to help you but if you do long runs and the breathers blocked it will suck water in any spots it can when the oil cools down at least thats what happens on tractors Paul

yeah mate Im with you I never heard of one either Paul

so its like the bait when fishing understand thanks for the reply thought that must have been what it was Paul

so whats the idea or meaning of a "dear plot" I know its proberly a dumb question but this dumb Aussie has got to ask ? Paul

325 ft lbs that will take a bit of swinging good to see you got your holes drilled Paul

well you never guess what I stumbled across this morning a spare copy of the magazine so if you want it you can have it just send me your mailing address and I'll bung it in the post Paul

thanks for sharing felllas those b lack R models in the top post are looking pretty sweet Paul

thats a pretty cool looking car there for sale I think there was something like that on American Graffiti ? Paul

Well if I come across another copy I'll pop it in the mail and you can have it as long as you take me for a ride in it if I ever come over to the states ,had a look to see if I have another copy and its the only copy I have but I will keep an eye out you never no what might turn up seeya and as we say here in Australia you "keep the dream alive" Paul

Gudday Red welcome aboard you no they made a movie about you and wrote a book Paul

well there you go might have answered some questions with out even knowing it pretty smart hey wonder if it all still works on the truck ? Paul

does any body no what happened to this big idea ?seems like quite a smart idea Paul

have seen a few that are hooked up this way but dont cock there leg or just to real different you could have them do the Panda when you wanna wash your wind screen Paul

how for so you come up with that answer and do you no what all them there hieroglyphics mean as I have often wondered and have no real idea does anybody no if timken and rockwell centers are interchangeable ?? thanks in advance for any answers this dumb Aussie skippy the bush Kangaroo is wondering Paul

I dunno what the rating is but the reason I said I thought it was small is it dosnt have torque rods must have them on top of the diff center were as when they get a bit heavier they had a six rod set up and the heavy duty had an eight rod set up but I could be most likely wrong though Paul

moving right along there Timmyb I would think any bit of rust proofing would be better than none Paul

sounds about right then I should read things closer Timken axles became or were bought out by not sure which Rockwell in the 60's I think Paul

yes this leads to the problem that is all these things are old trucks and most werent meant to go real fast and dont have the power to if they are geared to go quick any hill or head wind makes it time change gears

Superdog I know why you bought it just to remind your self how good a Mack is looks like a Timken back end to me might be only light 30000 - 34000 lbs they are the only brand backends I have seen with the oil filled trunnions and the springs on top like a Mack Paul

maybe just crook head gasket pull some injectors out of one head at a time see which head is leaking Paul

why dont you put the second 3 speed box in backwards it will then give two good over drives and will solve all your problems Paul
