Somebody didn't like walnuts?

No sir, SHE did not.

Hey Jocko.....is yor dawg Man or Female? Why I ask is I found mine by accident by looking at the dawg getting ready to take the radiator out of the truck. Here's a photo of it if it will download. Some of my photo's are too big for the site.

We used to have a Bulldog painted on the wall at work. We had a couple of trucks that had been in a fire, so one of the guys took the old black shift knob balls off of the sticks, they were all wrinkled up from the heat and kind of shrunken and off size, and hung them on the wall-that didn't last too long

I think Cummins manufactured some horizontal engines for use in buses and coaches back in the late 70's. I'll check tomorrow and see if I can find the model ID's for them.

I forgot about this yesterday, here are some model numbers and specs. There may be more of these horizontal engines than this.

HHR-6 (5 1/8" x 6", 743 cu in, 2 valve, naturally aspirated)

HHRF-6 (5 1/8" x 6", 743 cu in, 2 valve, naturally aspirated)

NHH-180 (4 7/8" x 6, 672 cu in, 4 valve, naturally aspirated)

NHHE-180(5 1/8" x 6", 743 cu in, 4 valve, naturally aspirated)

NHHE-195 (5 1/8" x 6", 743 cu in, 4 valve, naturally aspirated)

NHH-220 (5 1/8" x 6", 743 cu in, 4 valve, naturally aspirated)

NHHRS-6 (5 1/8" x 6", 743 cu in, 4 valve, supercharged)

NHHT-6 (5 1/8" x 6", 743 cu in, 4 valve, turbocharged)

NHHTO-6 (5 1/8" x 6", 743 cu in, 4 valve, turbocharged)

NHHRT-6 (5 1/8" x 6", 743 cu in, 4 valve, turbocharged)

NHHRTO-6 (5 1/8" x 6", 743 cu in, 4 valve, turbocharged)

I'd say the reason you only had a lone Mack engine in your class was that the majority of those engines are still out there working today. It's good to see that there is still interest in the mechanical field as a career. As far as specs for your engine are concerned, I think Barry has posted the mechanical fits and limits chart for Mack two valve engine in the Wiki. Try to get your school to buy the Mack service manual, number 5-672SERIES100.1.

This i dont think is a DM so would it be a RM?

The RM should be all wheel drive. I think this is an RD8 chassis.

Seen this.

That doesn't look like too bad of a price for a triple frame truck.

I don't know the name or if this applied to the early years or not,but during the '70's &'80's,Mack shipped the trucks to the importer/dealer "CKD" Completely Knocked Down,and were assembled upon arrival.

They still do that with some of the imports (South America).

Whether he was right or wrong, this seems like it would have been a helluva good blowout to see in person.

Hey Otherdog, here's a creepy mirror for you.

Oh please:

Ste. Claire, Quebec, April 7, 2010—Prevost is proud to announce that they will manufacture all of their vehicles with Volvo’s D13 Engine.

OH MY GOD! REALLY! AMAZING! Just what I have been waiting for my whole life! (sarcasm)

As if they would have announced anything different. Of course they are going to try and sell their own name, they are Volvo. Arrogant jerks.

I think (not sure as I'm not a motorhome type of guy, and even if I was, theirs are way out of my price range) traditionally Prevost used Detroit engines. Seems like I saw somewhere when looking for this information that it was Mercedes' decision, not Volvo's, to pull the Detroit out of the Prevost as they did not want their engine being used in a competitors chassis. Volvo probably would have given the Detroit engine the axe anyway for the reasons you stated. I think Mercedes just beat Volvo to the punch on this one.

That is the direction i was headed in, i got home from work early today and started removing the fuel line i got the feed from the tank to the filter off but since i got the info from rhasler i am taking it back to performance and let them change the data files to the correct ones and let them know a real mechanic diagnosed the problem, i wish i was close to his shop and i wouldn't have to fool with these people....so glad i found this site, who know's where i would be without all of you - thank's everybody

Don't forget fjh and Mackpro68, I just did some of the leg work.

i only have 1 mack dealer here. How would i go about getting it cause my dealer says that mack does not stock it anymore

I don't know if it can be drop shipped to you or not. I would tell your dealer that you know better and then give them the part number you need.

i was sitting at wotk today looking at the macks hauling by the shop and got to wondering if mack ever made any DM 700 series trucks i know they made the R models in the 700s but ive never seen a DM 700. joe

I don't see that any were made. The record skips from DM668 to DM807. Doesn't necessarily mean none were made though.

vin#1m1aa13y54n156276 4mr21084 that's the complete vin number

That VIN still shows that the VECU datafile is setup for an FRO15210C transmission. If you have changed the transmission you need to have the datafile changed as well. I have run into this changing from a 13 speed T313 to a T318 transmission (they have the same end ratios) even though the parameters for the speedometer fault were removed. Also this is an ASET AC engine, and not an Etech CCRS, which has problems all it's own.

VECU software is 1MS364 with datafile 1MS365 (step 9B), EECU software is 1MS368A with datafile 1MS5166P13 (step 3A). If the turbo has been changed it should be a 631GC5176(A,B,C,or D)X. The original turbo should have been a 631GC5171. You need to replace the drain tube on the turbo with part number 681GC544

and then have the EECU flashed with 1MS387 software and programmed with a 1MS5183P13 datafile. You will need to contact Mack One Call and have this information changed and set up, you will then need to take it to a dealership and have the modules programmed. Make sure they calibrate the throttle and turbo after programming and enter the EUP cal codes. If you take it back to Beaumont make them do it for free, since they should have checked/changed all of this already!

Look at the picture close. Is that a Cummins on its side? The exhaust is really high to with a spark arrestor high towards the top maybe for a high cude box or canvas top straight truck? The frame is strapped like the older flat bed trailers. Is that a tag or lift axle in front of the drive axle with front hubs? Maybe its a steerable lift I can't makeout if there are tie rods or drag links? Whatever this truck is, it's pretty unique.

I think Cummins manufactured some horizontal engines for use in buses and coaches back in the late 70's. I'll check tomorrow and see if I can find the model ID's for them.

Hey OD, try this:

1) Go into the bathroom.

2) Turn out the lights.

3) Run the water.

4) Say "Bloody Mary" 3 times

Warning! Results may vary.

You may get this:

or you may get this:

Hey Dunny, I had a parts man check that number out, it's still a good number and it's available (literally hundreds in Mack's warehouses). He told me probably around $5.00

I twice found a rock stuck in the inlet elbow of the red fuel filter might be worth looking at Causeing a low power thing Again fluctuating fuel preasure UNDER load!

What is baffling is the boost the boost is right where it should be!

That's what's getting me too. What if you take the truck back to Beaumont and tell them you still have the problem and see if they have a test VECU for you to try out? If you just dropped 5,000 dollars with them I would think they would be concerned with getting your truck straightened out.

after every thing we have done to the truck mechanicly I firmly belive it is in the electronics and since i have changed the ecm and then had the new turned up to dump more fuel something is telling the ecm not to dump enough fuel or it's one of the other ecm's I do not kknow what this other ecm's control by the way my cruise stopped working after this happened

That is a possibility I suppose. Usually the VECU doesn't cause performance problems when it fails so much as it sets fault codes for various items it controls. The VECU is mounted to the panel in front of the passenger seat. The best way to describe its's operation is to think of it as your boss. It tells the other modules on the truck what to do and coordinates their activities, but doesn't have the ability to do their jobs by itself. I can't recall all of the functions it controls, but accelerator pedal control and cruise control are two them. I think torque limit is also one of it's functions.

Bad fuel transfer pump the gears on these pumps have be known to fail and slip on the hub the engine will still run but the fuel preasure will be erattic under load. Don't have much to say other than that!

Sorry for not bein able to help!

I have to second the transfer pump question. I know you've installed a new one already, but I have installed new pumps and had the gear on the new pump slip immediately afterwards.

This may sound stupid, but has anyone checked the fuel tank, pickup tube, and cap vents? I've seen tampons, fishing bobbers, and even ham sandwiches floating around in fuel tanks causing the same type of problem. I've also seen bent in fuel tanks restrict flow into the pickup tube as well as fractured pickup tubes.

On a 2004 vision sleeper cab tractor:

I'm trying to locate terminal points that are fed by the two aux. electrical power switches (battery symbol on one, key symbol on the other). I understand that the key symbol switch only provides power with the key on, and the battery symbol switch provides power at any time.

I want to use these switches to power certain items on a trailer. It seems they each have a power supply wire coming into them, and another wire feeding back out....Where does that outfeed wire go???

On the firewall, there is a terminal/stud bar arrangement that feeds the seven-wire trailer cord. This bar has 3 additional studs. I was hoping two of these additional three studs were powered by the two aux. switches....but so far, I've been unable to get any power at these studs with a test light.

Can anyone tell me if I'm on the right track?

You should be working with circuits 30 (ignition feed) and 61 (battery feed). I assume you have located the switch connectors in the dash. If you look on the edges of the switch connectors you should see numbers identifying the cavities of the connector. Cavity #4 on both connectors is the power out of the switch. The wires should be identified as 30-B-2.0 for the ignition feed and 61-B-2.0 for the battery feed. I believe these wires each terminate in a single pin connector that is brown, you will probably need to search through the harness to find these connectors. They should be on the right side of the cab somewhere in front of the bracket that holds the power relays. They should have plastic tags identifying them as spare ign. and spare batt. switch connectors and the wires going into them should have the same numbers printed on them as the wires coming out of the switch connectors. Another option would be to remove the terminals from the #4 cavitys of the switch connector, run wire into the cab as needed and crimp new terminals (925AM118) onto the wire which would be inserted into the #4 cavity.

so i found few DMs today. and would like to know what the diffrence is?? one is an 800 one is an 809 one is an 885 and one is an 886. what do the number designations mean?? also what are the DMs letter designations?? i.e. sx,s,x,...?? my gf wrote down one of the models and it says DM800k never heard of a k. i know all about the B model numbers but the DMs are new to me!! any help would be great!!!

The DM is for dump/mixer application, the cab is offset. The first 8 is the model series. 86 and 88 identify the engine type. Suffix letters are as follows:

P-truck, 4 wheel platform

T-tractor, 4 wheel platform

ST-tractor, 6 wheel

S-Truck, 6 or 8 wheel

SX-truck, 6 or 8 wheel, on/off road dumper mixer

X-truck, 4 wheel dumper

FC-fire chassis,

FCS-fire chassis, tandem axle

Keep in mind that these identifications are no longer in use. The number your girlfriend wrote down should be a DM800GK, indicating it is a DM800 chassis glider kit.

MMMMMMUUUUAHAHAH! don't be fraid' of no "booger man" LMAO!.............Mark

Holy crap! I was thinking of posting the exact same thing, words and all! Well not the "LMAO......Mark" part.

where can i get a blower motor resistor for a 87 superliner. dealer says no got! man I have a lot of trouble trying to get the simple things for this truck

The resistor part number for the RW in this post: http://www.bigmacktrucks.com/index.php?showtopic=15191 is 4379-RD536470 (or at least it used to be). It was built in 1987, so I would imagine it should be the same as yours. I'll try to check on it tomorrow and see if it available or if they're just blowing smoke.
