one thing I question.... do these trucks take into account the need for front loader, side loader etc ....options. Here in Chicago land we have several types of garbage trucks used for very specific jobs. Most Residential trucks have a side load arm with a front bin. commercial is either front load with forks or rear load with a dumpster. Industrial is more of a roll off swapping out compactor bins. what Im getting at is none of these trucks are loaded by hand these days. Will the battery life span be able to power these loader options or is it only able to propel the truck thru a 10 hr day? I honestly think a Diesel Electric may be the better answer for now. a Smaller diesel charging the batteries as the electric motors do most of the work. but thats just my observation

I still think that Mack does not have the solid Platform to build off of like they did in years past. Today I see Pete,KW,Volvo,IH. they all have a truck that can accommodate the largest of engines available or they are simply fitted with more fleet spec power train. Mack has one truck option and it has 2 hoods that honestly look the same at quick glance. Mack is lousing sales in just about every market . forget about total overall sales for a moment as IMO that is just a sign of what the economy is doing. When you start to louse market share. that is showing that your product is no longer the must have brand it once was. If you look at what Paccar has done in the last 10 years to infiltrate the concrete and refuse market its clear to see that they are continuing to do exactly what they did to push into the Dump truck market 20 years ago. They offer the buyer options with their truck. Paccar has both their old square hoods and their new aero trucks. A single truck owner or large fleet company has the option to pick from and build from there. Mack has the exact opposite. They simply did not stay current with their offerings and in fact moved to a more basic spec platform to cut costs. It may have saved them money on building trucks but it has cost them their large market shares that they once enjoyed.

I have never worked with the heavier Mack rears but I see it has a cap that can be removed. I would pull that off and then see what it looks like. If its possible to jack it up from the center tube or lift from the rear of the frame that will show if it has to much slop. it will also help push grease into the bottom of the bushings when the weight is off it. Pull that cap and let us know what you find

Yes. for how new it is and for long it has been down or acting up on their own watch. the easy fix is for Mack to stand behind their product and just use it as a test bed to find the issue so that this does not happen to other Mack owners. Its a win win for both. you get a new truck and they work out a issue on a lemon to improve and learn from it. I would start barking a little louder and present them with a time line of documents to show it plain and simple that the truck is a lemon.

I know how to fix it....send it back and tell them you want a new one and let them sort it out....I know easy to say than to make them do but for real...this is BS on their part

Its part of the power divider How are the U joints? does it make this sound every rotation of the wheel?

Then keep It!!! You are well ahead of most if its still turning a profit and its paid for! These new junks out there are comfy but they are very costly to maintain when things fail.

looks pretty straight. I would think around 8k to10K for it. ??

Another reason why I will never be seen shopping in that place. its been almost 10 years and the only reason why I did stop in once was because I was out of town and in the middle of nowhere.

I was not aware that there was different input sizes available on mack diesel engines?....All I had ever seen was the industry standard spline. I thought The main change needed to swap between Mack or off breed transmissions was just the bell housing so things would bolt up. Learn something new everyday! I would agree staying with a road ranger just for the fact that you have a Overdrive and the bell housing for it to bolt up.

I hate the old style with the 4 caps that need to be pushed out. Some come out easy most are stubborn. the ones with the straps are way easy to remove and i feel they are less prone to damaging something when removing them

The rear cab bushings are easy to replace but to be honest I dont think it will do much to make it ride better. Cab air ride would be better if the truck is set up to convert over fairly easy.

Time to call HQ and explain this situation . This is absolute BS and I wonder if the dealer is trying to sweep this under the rug somehow.

They likely used pipe dope or some sealant type as thats all I have ever seen on fittings I have pulled off a block. heat will help soften the stuff but dont go using a blow torch on it turning it orange. a heat gun might be better to use.

How many miles are on this truck?

Some interesting things in this pic if you look close. I sent it off to a friend that is a race car historian to see if he can give clue to the year of the race car in the photo. Regarding the Mack AC I cant pin point the year of the truck as it has some odd features. 1) its in front of the International motor Co building but the truck says MACK 2) square fenders on the AC. most were rounded 3) screen mesh on the hood. most were louvered 4) hood looks more rounded than a standard AC hood 5) no side louvers for the radiator. its sides are flush with the cab cowl

I could only see it on my phone......the vid was not very clear for me to see where the issue is as the RPMs were always moving up and down and I cant gather where in the RPM range the vibration was or how bad it surges when you hold the RPM

Nice looking lowboy tractor

I drove a granite with a MP8 for the first time the other day pulling a 3 axle low boy with a PC160 and a few spare attachments. was only about 80k gross and I was fairly impressed with how smooth the engine pulled the truck up to speed. The engine brake was very strong as well, I popped the hood and what a mess.... All I could think was that although the engine was pulling great I know one day will come that all that emissions crap will fail and render it a POS and cost the owner thousands. If I was to own one of those trucks I would seriously look to pull all that stuff off and just let the diesel do its thing .

sounds like the dash switch is bad or the inversion valve is bad . the dash switch has 2 ports that one or the other has pressure going to it depending on the position of the selector on the stick. if the inversion valve is sticking it may be stuck half open and exhausting when it should not be? someone just posted this pic the other day

I bought a set of white walls for my old Cadillac about 10 years ago. company called Coker Tire was producing them but they make them for hot rods and pickup trucks only. I dont really like them on Big trucks but think it is kinda cool to know someone made them

there is a company up here in Palatine IL that has done work for just about everyone with a old truck that needs springs or older parts http://www.spring-align.com/ they do just about anything but not sure how helpful over the phone as with most shops they want to see it first.

might want to save the mirror brackets if they are any good. if they sell for anything like the B models do you will make a good penny for them someday

Where does one get the White wall tires in truck sizes?

was that on a mack engine? I ask because I think on a cummins or Detroit it can cause vibration if the compressor is not timed or something. I recall a old timer telling me about that when i was putting a compressor on my 285 Mack. I have never done a compressor on cummins or detroit so Have no clue.
