last six of the vin is 010283

The parts list shows two air tank part numbers which are supposed to be interchangeable. Both are labeled as steel. Part numbers for the tanks are 22QE41212 and 22QE31053P2. They are described as being 22 inch diameter tanks with 8250 cu in capacity. I haven't been able to find an aluminum version of that tank.

Thank you. Is M142 the reason why my odometer stop working? Since these codes came up my odometer reading has stopped.

It is most likely the cause.

I am getting these 2 fault codes 5004-02 M136 and P084-05 M142. What does these codes mean?

The M136 fault code is ABS sensor 4 (right rear axle wheel speed sensor) erratic reading from sensor, the M142 fault code is road speed sensor (in the transmission output bearing cover) open circuit.

There must be a problem with the serpentine belt.Just get your car to a good garage.

Geez man, you come up with some absolutely rediculous bullshit that has nothing to do with the problems mentioned consistently.

Unless you have something positive to offer up for a problem someone is asking help for, please retain your thoughts to yourself as they are of no help.

Rob

I thought maybe I was being overly sensitive, but I guess not because it looks like Rob is on the same page as me. I read these posts the last few days and couldn't figure out why anyone would post such nonsense laden drivel.

Damn, I think we got us a genuine "Genius" here. I could be wrong, but I've never in seen an E7-350 Mack Diesel engine with "spark plugs". Maybe this is some sort of "new" technology Volvo has incorporated I'm not privvy to.

Maybe the prior poster is deriving his clues from a magic "8" ball.

Rob

Sorry to tell you Rob, but he's a "Truck Engineer". See his introduction post: http://www.bigmacktrucks.com/index.php?showtopic=14898&pid=59915&st=0entry59915

i have aa 91 r model with the large air tank that looks like a beer keg, well it has rusted through under the straps and naturally is now leaking air. anyone know if there is a aluminum tank avaiable that would work? mack wants anywhere from $1100-$1300 which i think is crazy for what it is. anyone have any alternative ideas of has anyone run into this problem? its only a pin hole rite now and i would take it off and attempt to fix it but i dont want to open up a can of worms and open it up more. but i think the dot wouldnt be too impressed to see that.

The DOT won't like it if they find out you don't have enough air reservoir capacity either. Post your VIN or PM and I'll see if I can find an aluminum tank of the same dimensions. They did have aluminum air tanks for RD chassis, but I would expect to pay more for aluminum than for steel (if buying new).

sorry for the late reply. It's a 2005 MACK CV713 Granite. hope that helps

JerryB had a similar problem with his CX613. Your dash cluster is similar to his, but I think will have a different part number.

See this post: http://www.bigmacktrucks.com/index.php?showtopic=14797&st=0&p=59442&fromsearch=1entry59442

I think the DM is a RD800. It would be nice if these guys knew what they were selling.

The VIN they listed is for an RD822SX.

That helps!! Thank you!

Let us know what you find out.

2nd day down and I'm actually learning something for sure; stay soaking up the air conditionning inside cause it's hotter than the fires of hell here. Even my fat rolls was sweating. Momma looked like she just got out of the pool with her clothes on! And this was just walking across the parking lot.

Rob

Did they teach you how to build a death ray with all those fancy batteries yet?

As far as the trucks go you are paying for what you get. They usually price out higher than Cat (Is that possible? ) but are well worth the difference.

Do any of you guys know if the durability of the engines in the equipment is better than the truck engines?

On my dashboard i have I think 3 mounting holes for gauges right now they have black mack logo caps over them. Can I pop one of those out and add a Boost gauge is this a good idea and is it hard to do??.

The RB didn't have an electronic dash so even the factory installed guages were mechanical. You just need to remove one of the 1/8" pipe plugs from the intake manifold and install a 1/4" ferrule x 1/8" NPT fitting in the manifold, attach a length of 1/4" nylon air tubing, route it into the cab along side the oil pressure line, and hook it up to a new boost guage. This would help a lot in troubleshooting low power problems.

I have one of those 4 foot long cameras that are flexible and have a light on the camera end. Would this help me find a air leak under the cab maybe spray water on the line with a squirt bottle and with the camera look for bubbles.

If i have to take up the floor that sounds like my friend the torch has to come out and play??

Mark

No to both questions. The Cab floor board has a section that is bolted in that is removable. You need to remove the floor mat, guards, throttle pedal (fold the pedal back toward the seat and remove the two bolts holding it down, be careful reinstalling as the bracket is aluminum and the bolt threads easily strip out). After removing the floor board bolts the plate has to be lifted and turned slightly to get the clearance needed to remove it from the cab. It takes some practice but isn't too hard. The pipe will not show bubbles with the engine running if there is a hole in it because the engine and compressor will both be pulling air in through the hole.

Ok BObo so i might have an air ride cab??. This is my 1st Mack so Im still learning!! My other truck is a kenworth.

How do i know if my cab is airride?

There will be two air bags (item 45 in the attachment) in the center of the rear cab mount brace (item 69 in the attachment). The front cab mounts are a split rubber design with a clamp plate on the bottom (items 33 and 75 in the attachment). You definitely have air ride on your cab. Make sure to check the cab shocks too.

I sent you the vin number check your mailbox hopefully you got it.

I got it. You have an E-Tech CCRS engine (as opposed to an ASET AI engine). You can disregard the earkier remark about the intake manifold and elbow as thid was not used until the ASET AI engines were introduced. Another possible leak point in the boost system is in the air inlet for the air compressor. It is a metal tube that comes off of the rear of the intake manifold and wraps around the rear of the engine. These tubes sometimes develop a hole. It is really hard to get at on your chassis. The floor board has to be removed and usually several curses have to be uttered at high decibel levels before it can be removed, so check the easy to get at stuff first. I see now that you have a post related to the cab air ride. A sagging cab will cause the cab to push into the tube and rub a hole in it so you may need to check it anyway. This was also a common occurence in our area with the mechanical engines. The cab would actually bend and restrict the throttle linkage at the rear of the cab. Do you have a pyrometer or a boost pressure guage installed on the truck?

Hey man thanks again!. Do you mean the VIN number??? where do i find the serial number

Yes. It should be on the metal tag on the driver's door. If that tag is missing it should also be stamped on the right frame rail somewhere around the area of the shock absorber.

Guys I run a 2003 Mack RB688s dump truck with a E-7 350. I'm a owner operator.

Last month I had a loss of power problem I got on the site here and you guys all pitched in and fixed my problem. Rhasler had given me the exact problem and how to fix it I am gratefull for the help. Now that the truck is back on the road with a new speedo sensor and a new fuel transfer pump I didnt get the power that I thought I would gain.

Now the only thing I didnt do as was suggested was to bring the truck to a Mack dealer and have them turn off the parameter thats detects the tampering with the spedo sensor to prevent the derate power.

My friend has the same motor in a RD688 and he pulls a trailer with his machines on it.

My truck wont even entertain that idea!.

I just seem to have the RPM's to shift her to get her ass in gear.

Now when the truck is not loaded it runs like a bat out of hell.

Mark

Give me your trucks serial number and I'll check some things out for you. Probably the easiest (and cheapest) thing you could do is give the engine a good visual inspection. Look over the exhaust manifold and turbo closely for signs of exhaust leakage and cracks (particularly at the center manifold section towards the cylinder head and at the turbo mounting flange). Make sure you dont have any loose charge air cooler hoses, and check the intake manifold elbow. The original clamp holding the elbow to the manifold was a worm type clamp that would loosen in service causing the elbow to wear against the manifold resulting in loss of boost pressure.

Volvo makes the finest articulated truck hands down. They are smoother, quieter, and more powerful than anything else on the market today. The loaders are pretty good too. I haven't had any experiance with any of their other equipment.

That's what I had always heard about them. I wasn't sure of the cost on their equipment though. It seems like the majority of the equipment used around here on local projects is Volvo.

Hi there,

I am looking for information for my Dad, who has a (we think) 1927 or 1928 c cab, worm drive 2 ton mack truck w/ bud wheels. Serial # 374726. We'd like this confirmed? If anyone knows anything about it, or how we could find out please let us know!! I can be emailed @ chellelorenzen@gmail.com

Thanks!

Michelle

Have any of you guys owned or operated any Volvo Construction Equipment?

Hot here again today.

Took out some steaks for dinner

Was all ready to cook them on the grill

Decided it was too hot to cook on the grill, but I remembered hearing about a guy walking barefoot on the pavement with this result

So I decided to throw the steaks on the pavement and see if they would cook. I think they were out there a little too long

Doubt I will work it, been right hand drive it would probly not met your legal requirements. mainly shows I spose? I drive alot of triple roadtrains down here so its set up for that sort of work, no triples over there yet. I would like to bring over a container side lift aswell, but dont have the money to gamble on that been able to work over there.

Grant

I know there are right hand drive autos here. I don't know that a truck would be any different in that respect. Weight and length limits would probably be the biggest problems. Maybe emissions too, if the engine is set to Australian emissions levels. It would be really neat to see it though because apparently there aren't (m)any here.

Actually did something along those lines once and the reaction was less than positive. I let the air out of concealed balloon I'd hidden in my shorts underwater in clear view of a few that were watching me and let out a giant "Ahhhhhh". Most that weren't laughing, left saying I was gross.

I remember the "Baby Ruth" bar in the swimming pool routine well. Good movie.

Rob

Man you are too much Rob.

Hi, a 1969 flintstone converted to a 1970s R700

Grant

Hi Grant. Sorry, I meant will you be working it or what exactly?

I used to run all the big cats, but when I struck out on my own, I like Komatsu,,parts cheaper,,easy to work on and stout as an elephant,,,just my 2 cents. In the past few years, cat has had a real problem with electronics and computer programs on their equipment,,,causing lots of shop time,,,randy

Randy, for some reason it looked to me like you have a handlebar mustache in this picture (until I clicked on it to make it bigger). Might be a good look for you, so keep that in mind if you need to change the facial follicles in the future. One of my neighbors has an old dozer sitting behind the house, one of these days I'll see if I can find out what it is. Seems like it's been sitting for years
