This point just that to try understand the principle of how those operate not all the issues of this thread in total. In the same year the company opened dealerships and service centers across the state of Massachusetts to sell and service its equipment. Let's hope the initial low cost will cover the upkeep. That's how we built our legendary reputation for quality. Will be watching otherwise out of this as Cornbinder at least would have a clue or full know how with this - I don't, I wanted to add that my truck uses a viscous fan clutch so it is controlled internally. If the outlet of the evaporator is cold enough to frost, than I would look for air bypassing the evaporator, or heat leaking in from heater being the cause for warm outlet. I didn't even notice Well, thankfully, with the new site it's a breeze to move things.
I also replaced the txv and reciver dryer. I am not one to over charge but that seemed low at 80 degrees ambient. I would say that at work and on the side I have successfully repaired about 25 vehicle air conditioning systems. Candidly speaking, you should sell it at the first opportunity, as parts will always have to be ordered, cost a fortune, and most mechanics have no experience working on it. Renault Trucks does a superb job with after-sales support in the global market, but has no presence in North America. So now I re hooked up the evaporator temperature sensor.
Heat is absorbed when the refrigerant goes thru the phase change from liquid to gas. If this code is accompanied by a 7-5 code then there is an external voltage problem. In 2003, Volvo decided to terminate the Freedom and walk away from medium-duty in North America Mack had profited greatly from the Renault-produced Mid-Liner medium truck range from 1979. The freezing condition is gone now but I feel the pressures are still off and the performance is poor. You should feel the liquid side into evaporator line as close as you can and outcoming line should be within just a few degrees or charge isn't correct yet.
With 134a the smaller passageways are better more surface area contacting the refrigerant. Turns out between our 3 dealerships, we only got one Freedom truck to sell. Also, Volvo Group's unofficial policy is not to support trucks over 10 years of age. The series is the best in its class ratio indicators such as the power-to-weight. Weird pressures which were caused by holes. Mack Series B receives the most popular among buyers. In 1901 Harris and McGuire, New York sightseeing company, was released by the first bus Mack with an engine capacity of 40 horsepower.
This helped to reduce the braking distance of laden that immediately had a positive impact on road safety. Could something be problematic because the old condenser had large passageways and the new one has small passageways? I too think it calls for more refrigerant. I have owned mine since new and have been very satisfied with this truck. So I ended up needing a condenser. On one of my trucks I added a Red Dot air controlled water valve to the heater circuit, that is controlled with an air toggle switch on the dash.
Issue truck cab with such a configuration dictated by the need of compliance to regulatory restrictions on the length of road trains in some states. If the processor is running then there must be an internal problem. These trucks have been successfully used for long-distance transport and intercity. And the urban C50 vehicles with frame-panel bodies turned out to be so successful that they were not only ordered by New York, but were also produced under a license called Metropol in Sweden by -Vabis. At the same time produced diesel «Maxidyne», having a five-speed transmission «Maxitorque» - a prototype of a modern automatic transmission.
A putty used to seal its tube alone can throw them way off if not sealing. I would try and find another reference for the amount required, 2 lbs just doesn't seam enough and the pressures seam to back that up. When the allowed maximum length of train in 45 feet 13. That is what my book shows. So the Freedom was only sold for 3 years, and hasn't been sold for 15 years.
I'm sure Volvo will fall all over themselves trying to help you sarcasm on my part. I will check for evaporator inlet and discharge temps to determine if the charge is correct. What all this means is: if the Tx valve is too small or too big it will effect how well it works. I have never looked at macks before so could use some help also if someone owns one like this how much does it weigh mack dealers all have a differing opion of the actual weight thanks for any insite Sounds like a find if you are happy with the price. I pulled about an hour and a half of vacuum. The heyday came just in the 50s of last century. A sight glass too far away from the expansion valve, under certain conditions can show flash gas bubbles or oil globules, which can be misleading.
Year 1950 - updated lineup Mack truck series B, H and G. Still, there is a thermostat probe going into the evaporator which should prevent a freeze-up. Even less than my 9670's. If you hadn't supplied the spec, I would have thought you are low on refrigerant I am thinking there should be a frost switch to shut off the compressor when the evaporator starts to frost over, Are you just seeing frost on the outlet line or is there a reduction in air flow and frost on the evaporator proper? No matter where you travel, you can depend on legendary Mack parts and services you'll always find at your Mack dealer. Thanks, I will check for Renault Midlum manual since cab and engine are Renault made. In many cases I have to add a manual shut-off on the heater hose if there isn't a manual shut off on the engine. The truck in general doesn't seem to be in bad condition by the looks of it at least.
