I'm with Bob Watch the spray they need to be cracking at similar pressures around 3000 psi With no dribble!

Yup I agree! Good on them! Right down to earth well grounded dudes with a focus! I question the usefulness over the road also! the Cab makes huge sense as vocational units As they were saying the visibility alone is a true bonus! The Idea of haveing everything generic is a true savings in the logging game! thing is , everything as it is these days is to create more business built in obsolescence is In order for them to have that they must have something to sell after the sale of a unit! there growth will be limited ! they have no captivation not even the Cab ! I believe the repower idea is a sound idea! repower kits makes sense! still a huge undertaking for most thou!

Thought I would post this ! These guys put a shitload of common sense to use here ! Hopefully they go some where with it ! They definitely wouldn't Be hired by any of the corporate type companies they are too logical! There veiws reflect my thoughts for the most part as far as saving the environment they hit the nail on the head! Not sure how this will work out for over the road use as their main focus is logging how ever.......!

With out an engine brake you will have no issue mounting the Tip turbine ! Just make sure the stud nuts or bolts to mount it are in the correct locations when installing the head bolt/ studs! The three that mount the bracket to hold the cooler box have to be located properly is all!

That is a beautiful trip bro your missing out! We Have done the Alaska Yukon trip twice !

Bro Sorry I'm not a guru on this subject! I apologize for the use of memory word! The engineering dudes figured it out for us ! Some how the extra turns going in didn't match up the turns going out to the diffs and compromised the ECU in one of the chips whether it be memory or OTHER not sure sorry I used that as an example! Again ! The point being the computer over worked it self in that area trying to figure out what to do and couldn't ! The same area got damaged 3 times it showed burn marks each time ! It was and MP10! They ended up reworking the ECU some how OR ( MAYBE reprograming it to ignore the calculation) not sure Don't really mater amazingly enough they worked with us to repair the issue that's the main thing and the customer got satisfied! At that time there were some decent guys in that department don't know about these days!?Guess if you think about it if you stick extra gear reduction in behind everything It may have Miled out the brain of the ECU Duno! So Can't really tell you the solution!

Front after coolers came out early eighties The super liner was the first stab at it i believe I think Mack was the first to introduce them everything was 3 inch tube at that time! but I could be wrong but Mack saw the benefit or air to air long before the rest of the pack water to air was the media of choice for a lot of years! shortly after the superliner was introduced all other manufacturers started using the concept ! The tip turbine set up can be adapted to the 4 valve but would be labor intensive and if you add an engine brake there is a special adaptor to offset the turbine mount and would be scarce as hens teeth to find!

Boost or pyro????
fjh replied to Licensed to kill's topic in Antique and Classic Mack Trucks General Discussion
I too vote pyro! I personally would dump the diff temp ! Put a boost gauge in ! Both tell a tail if you know what your looking for! Diff temp for a toy hauler is useless in my mind unless you plan on running the diff out of oil! Must have list for me are the two mentioned as well as voltage / water temp oil pressure ! -
It varies even between provinces here ! As we all know they never do away with laws and rules they just Add more of them!! When I got my mechanics trade ticket We were able to attach the Air endorsement to the license That enabled me to drive any Wheelbarrow / car or bicycle with air brakes! These days you have to take a 15000 dollar coarse to Drive anything over 17300 with air! AND Rightfully so! as in the passed 5 to 10 years the increase in trucks and loads hitting overpasses has increased 10 fold! At least 5 last year alone in Vancouver area here! That said Safer to ride your horse! as the population increases the dumber they get!
-
Nice to see you hanging out Kevin! Nothing sounds nicer than a V8 Still miss the sound on our hyws here! the v8 and cab over population is slim here now ! We sold loads of these in the eight's ! Now a days the engine sound would be stifled anyway by the DPF ! you wouldnt be able to hear how pretty they sound anyway! 🙄
-
That came with 300 or more HP if I recall ! 285 was usually air to air only!
-
Well that sucks I have heard of valves sticking on occasion ! guess you will find out as you pull it down! Does your unit have a chassis mounted charge air? (bonus) or tip turbine style intercooler😪 ! ?

New/low mileage Granite with wandering axles
fjh replied to timmer62's topic in Driveline and Suspension
I can see by the pic the ubolts are not as tight as they should be! These are to be torqued to 1600 ft pounds I also notice the spring packs apear to be non antisway packs which doesn't help the situation ! Anti sway have more and thicker leaves above the three bottom leaves and have less give to them! For some Dam reason the pump manufacturers use or spec the cheapest chassis they can get their hands on ! Springs to small not enough brakes 24/24 brake pots ect ! you also have the cheapest spring saddle for the job there ! Your saddle has know ears athe very outsid of the saddle ! It kind of angers me in away that they are allowed to build stuff this way! Something that is eternally loaded gets built to such low standards! Putzmeister ,Concord and others all guilty of doing this! There seems to be no rules in place for these units! check out the different styles here are some examples !

E7 Mechanical Stumbling & White Smoke Intermittently
fjh replied to Salpolit's topic in Engine and Transmission
I much rather have the light set up its so much quicker ! And more accurate ! That said if your in a situation where the tone ring in the pump has moved. pressure timing is the best second method ! I have also used a drop of fuel on number one delivery valve to get it close on one occasion due to a slipped tone ring! and know flow timer available! you have to have a keen eye for that one put your glasses on! 🙄 Got to do what you got to do! -
If your harness has oil push you need to replace it and the offending sensors ! Also ! So you wouldn't happen to be running an extra trans ? (b box) We added a four speed b box to a titan at one point for low bed heavy haul work at one point It maxed out the memory in the ecu and put the truck into derate after 3-6 months of use! Went thru three ecus before engineering was able to tell us what had happened and why! And conjure up a work around! The board in the ecu had a similar look to it!

E7 Mechanical Stumbling & White Smoke Intermittently
fjh replied to Salpolit's topic in Engine and Transmission
The goal is to deliver enough pressure to lift the delivery valves not sure of the pressure Joey! It’s abit time consuming as you need to cap off the return lines ! -
E7 Mechanical Stumbling & White Smoke Intermittently
fjh replied to Salpolit's topic in Engine and Transmission
That is called flow timing and is the optimal way to time it it flows till it stops that is port closing ready to inject! if you don’t got stuff to work with the above is the next best option! -
All you need is a 5/8 box end and 11/8 box end to set the valves! don't waste money on the the tool even if you can find one! This is the method used to find it! If you think you have a head gasket leak or exhaust leak set the valves up this should help clean up the smoke issue then fix the dyna tard or ring or solenoid ( Note you have one old style and one new style solenoid) the old one is the leaky one! ( Also check to see if that sol is tight ) they can come loose! put the valve covers on ! start the engine while its still coolish run a garden hose around the area you suspect the leak is when you reach the the bad spot the sound will go away or change! Have seen these H G leak between the heads on occasion!

fjh replied to Salpolit's topic in Engine and Transmission
Yes! this here is a get by ! if you don't got the tool Joey has there! Remove the plug in front of the throttle and below the stop that's where the timing tool fits turn the engine to where its to be timed to example 17 or 19 there should be what looks like a flat blade screw driver DEAD CENTER in that hole! If its not there or not centered is either on number six or its out of time! Set it so the spade is centered in the hole remove the front cover and loosen the 4 bolts on the slotted gear turn the engine to on mark you want to time it to confirm the slot has not moved after you move the engine on its timing mark tighten the bolts and try it see if you have achieved your goal engine timing is usually marked on the valve cover and the marks are on the flywheel center bottom! and note if you have a 5.9 Cummins with this pump on it the set is very similar. Also note that We have run into a situation where by the spade has slipped on the pump cam ! this becomes a little bit of a pain but can be over come by a different method so for now go with the spade in the hole method! and advance the timing two or three degrees at a time! A bit time consuming But doable! -
If you can post some pictures of what your setting to! damper and pointer! Im gathering the pointer is missing! also number 1 and 6 are sister cyl if six is rocking your checking set on one! if two is rocking you are setting 5 and so on in firing order! Im leaning toward a lifter failure Pull the pan to check this ! however I have seen the engine brake slaves fail on these and wear in on one cyl ! I will also note that a lifter failure is ( usually) accompanied by a popping sound in the intake! air cleaner!

fjh replied to timmer62's topic in Driveline and Suspension
A lot of times the pump manufacturer removes these torque rods to the frame to make room for the syringe rams the rear one is usually in the way! Specially on the mack diffs! The only real way to correct this with Camel back or hard tail walking beams is to be sure you have the steel side blocks in the buffalo pad boxes! Its a dammed if you do dammed if you don't situation! Their only other solution is to move the pump back on the frame which will throw of the weight distribution of the rig Also If the unit has Greased trunnions the unit should be jacked up when being serviced ! Quite honestly a pump unit is ideal to do this it has legs! Lift the unit off the ground and Grease it it will last a log time if you treat it right! Additionally you need to keep an eye on the u bolts keep em tight! The problem with a pump truck is it is eternally loaded ! No rest for the wicked! -
Mack granite oil blowing from turbo down tube.
fjh replied to trucking251's topic in Engine and Transmission
I think you will find that your turbo is fubar ! Regardless of its age! we had run into this on many occasions ! when warm / hot Pressure builds up on the exhaust side of the turbo under load and moves down the turbo shaft to the drain tube causing base pressure! But another question ! have you been backing up hill alot ! if so there is a kit to move the breather to the valve cover for cases like this happened a lot with mixer trucks and some dump apps when working on adverse! just sayin! -
Preferred exhaust expansion font.
fjh replied to Licensed to kill's topic in Engine and Transmission
Joe is correct I know this is a toy or play truck but if you were able to be under the hood while a truck is under load you would be surprised how much an engine moves around specially pulling big weight! -

fjh replied to Licensed to kill's topic in Engine and Transmission
Think as stainless flex and two band clamps job done! Just leave a foot of flex space or it will break the flex! -
It’s likly a 375! If it was a 325 it would likly have a six speed Trans!
