I registered "Sheila", my A-40 for the show. I'm sure I'm setting myself up for a good embarrassment!! All in good fun, (of course)!! Rob

Hey wedding guy. Nobody cares here. Rob

You mention the condensor is horizontal between the frame rails. Is it standing up, or laying down? How much higher is the compressor than the bottom of the condensor? Rob

What is the square inches (surface area times rows of tubes) of both your evaporator, and condensor? What are your suction, and discharge pressures? Average temperatures, and humidity levels encountered? R-134 readily accepts, or absorbs heat, but is slow for heat rejection. This is the reason for the design difference in the two condensors. A square tube has more surface area for heat rejection. Condensor design, placement and proper airflow are critical. You do not mention ducting for the "muffin" or axial fans forcing air through the coil either. Also, what type of expansion device is incorportated into the system. Do you have an accumulator or receiver/drier with a sight glass? Because of static/dynamic and radiant heat loading in a motor vehicle application, you can just about double or even triple the needed cooling capacity for mobile applications as opposed to household needs. Just keep in mind that you also need to dehumidify the occupied space rather than just make it cold to be comfortable. If you place a "too large" capacity air conditioner in a space, a person will not be comfortable, but will be cold. Also, if you are like me and ride with your female companion, your ears will be on fire. Rob

Well, me and the owner came to a conclusion, and I to an ageement on the RW-613 this afternoon. He concluded he needed $5300.00 for the truck as is, and we were in agreement that he needed to retain ownership of the truck. Oh well, the search continues........ Rob

My yellow dog has 10:00X20 rubber with 6.34:1 rears and runs a "blistering" 58 MPH against the governor. Rob

Naturally I did not have my camera with me to provide photos.... I seen it at a truck service garage while wandering around coming home from work. Truck is a dumper (not a Gallion bed, but starts with a "G"), has a 10 speed, and a blown E6-350 with a "self ventilating block. The cab and interior are nice for the year, and the grilledensor is not beat up. The main problem is the back half needs cut off and replaced as the frame and all the suspension bushings are shot. I haven't seen a double frame that new split so bad from rust in my years of being around trucks. The rear suspension is also taperleaf, and the springs are misaligned due to bushing wear. The trunion shaft is grinding into the trunion itself and go figure, it has new caps on the rears, but the owner says it drives very well!! I thought if this could be bought cheap enough it would work for my detroit project (even though it would be a "halfbreed". What do you guys think is a fair offer he is asking for? I'd be happy with scale prices as I don't need the dump bed and the owner could keep it if that could be worked out. At least the brand is right. Rob

Thanks Superdog for your time. I shoud be getting my cab back from the blaster any day now. It's not jamming my schedule up as I don't have a lot of time to work on it anyway at this point. I brought the Detroit home today. What a load!! Here are a few pictures of a little bit of the challenge. I apologize if I annoy anyone with the pictures. Rob

Thanks for all the help. I located a #1 flywheel housing from a junk 8V-71, and now need to find a flywheel and starter. I'm sure the hard part is done with the housing. Thanks again to all. Rob

If you need others, or clearer pictures let me know. My email address is: rob@autoaffair.com. Thanks, Rob

Hi Chuck, thanks for responding. Do you know the web address for that site? I can't have any luck with google. Thanks, Rob

I have this 12V-71 Detroit engine as many of you already know. I wonder if a #1, or #2 flywheel housing from an 8V-71 series engine will fit to the back of this? My engine is from a genset, and has a 00 housing on it now, with a direct mount generator. I would also need the correct flywheel for the housing to allow for truck usage. Thanks, Rob

Hi Rod, I'm going to try to attach some pictures here. Hopefully they can help you out with your conversion. Rob

Hi Rod, it was still "raining like a cow pissing on a flat rock" over here yesterday so I was unable to get pictures for you. The sun is out this morning and I will try to get pictures this afternoon. Rob

Hi Rod, it is raining heavy here today but I will get you some pictures snapped and sent of the mounting. The booster cylinder is mouted to the Rt. side of the truck from the spindle arm to the front shackel mount. It would be the driver's side for your truck. I don't know if you will have to adapt a front and rear mount for the cylinder to mount on the opposite side or not. I will try to get you clear photos tomorrow if it stops raining. Rob

I don't know if it the best and definitely not environmental friendly but hot water at 2000 psi plus, following a kerosene bath with a bug sprayer while still warm does a good job for me. The pressure breaks off the large accumulated chunks, the heat keeps everything warm further softening the grime. My 2000 psi, 4 gpm steam cleaner does a very nice job with this type of task. Rob

A friend of mine has a 92? MR Mack that is a converted tandem tractor. It has been stretched, and is used in the septic tank install business. The knuckleboom crane will swing 360 degrees and self load/unload/place a tank, and all the pipe on both the truck and trailer. He really likes it because of ease of entry/exit, and you are right on top of the windshield when driving. Plenty of power with a 300 Mack engine, and 9 speed transmission. I've driven it with a 1000 gallon concrete tank on back, with a 580K Case backhoe on the tag trailer and it had enough power for the job both on and off road. Rob

Hi Thad, no completition from me. In fact I've had the same dilemma as you with the freight costs. Kinda takes the attractivness away from the truck due to distance. Rob

I talked to a guy about this truck earlier in the month. I was, and still am considering it for my Detroit project; The measurements seem to suggest it would fit. I wonder if the cab has been changed to the older style? It's always been said the larger cab change came with the 73 model year chassis. Me, I'm kinda partial to the smaller cab with "less" amenities. Maybe that is why I'm also partial to A & B models. Rob

That is a nice looking truck. I think it looks much nicer with fender extensions that do not have the bolt recesses showing. The picture of the other new Mack dumper that Barry had posted months back looked cheaply added onto with the fender extensions. This one looks much cleaner. Rob

Hi Tim, are they a straight or tapered pin? Rob

A power tower is driven from the input shaft of an auxillary transmission. This means that you can put the auxillary transmission in neutral, and drive the power tower output shaft with as many speeds as you have in your main transmission, ie. 4,5,6,7,10,13 etc. With the auxillary in neutral, the truck will not move as the output of the Brownie is not turning, hence the main driveshaft to rear axles. They are great for heavy winching applications. Rob

Fine looking trailer there Dave. Should be just the ticket to haul broken Peterbilts; Now all you need to add is a winch. Rob

That is my understanding also. You offer a very good explanation. Rob
