Engines built after 4/1/1980 used the new engine nomenclature. Rob

Leon, is your truck missing the emblem, or do you not have that type on your truck? Pretty certain I have one that is extra if you're needing a replacement. Rob

He is correct in the amount of parts to build the cabs but I think he blew you off anyways. The R series cab was a loose affair in comparison to the newer stuff but it really wasn't developed much after the 1974 model year with the introduction of the bubble back cab panel to correct the main detractor of very small interior room. Popularity carried that cab design for many years till "creature comforts" were needed to sell a new truck rather than brute functionality and durability. How many new trucks do you see produced with manual steering and no mechanical air conditioning? How about a manual passenger side window, or power/heated mirrors? Rob

There would have been some good sleeping watching that interview. Spoiled rich brat thinks she is above everybody else. Rob

The engine does not require electrical current to remain running once started. Rob

I've seen that very same thing in years past but on an automobile replacement joint. I've always pulled the caps to verify there is both a hole through the cross, and a hole with good threads for a zerk so the joint can take grease. I've had really good luck with Neapco brand joints also who manufacturers many of the private branded joints in the aftermarket. Rob

Looks like a "Reliance" brand transfer setup. Very popular in California although I don't know if the company is still in business. These are what my RL797L used in it's prior life. Rob

It's already taken a "set" to your truck. If it were reinstalled into any other driveline it would fail prematurely. Save yourself the grief with the cost of replacement and shipping costs with the prudent reuse of the product in your application. It's the green thing to do. Sides that, I don't know of any broke down Peterbilts right now that could use this part but haven't heard from anybody, so definately a possibility; or should I say probability. Pride precludes communication ya know as the constant drone of "I told you so" wears one down. Rob

What's all the fuss??? Just turn the joint 90 degrees and reinstall for another jillion trouble free miles. See, the fix was easy. Rob

I certainly wouldn't have any knowlege of anything like that. What is APADS an acronym for? Rob

I realize it is difficult to be third party and relay accurate information but more information as to how the cooling "falls off" is needed. You've indicated the system does not show the refrigerant being lost? I'm interested in how this is evaluated. An automotive air conditioning system is fully closed and not open to atmosphere so in theory should never be low of charge. This is not so true in practice. However from the description given after service the unit does work, (temporarily) and then the discharge air warms, with no loss of refrigerant, is an indication of either a restriction in the system, or defective parts someplace. Air conditioning systems are protected from both over, and under pressure. It takes refrigerant to circulate the oil in the system to lubricate mechanical parts. A loss of refrigerant will open a switch disallowing the compressor to function for protection. Also a/c systems make quite high pressure on the discharge side of the compressor. This is limited as a safety precaution also. Overpressure will also disable compressor operation. Either an undercharge, overcharge, or restriction in the dryer/accumulator, collapsed tube in the condensor, faulty thermostatic expansion valve or fixed orifice tube can give the symptoms described. In most never vehicles, if a fault is sensed in the system, the ECU will shut down and lock the system out preventing further operation till the fault is cleared from memory. I don't know if Mack does this or not. Rob

"Momma" got me a full set of "Tiger Tool" U-joint pullers and man do they work slick. Remove the retainers, set the puller, tighten it down with an impact and no damage to parts. Goes back together just as easy too. I tried the OTC branded tool and didn't like it. "Tiger Tool" I think is the best out there. Rob

HI Glenn, yes I've heard that before also. Lead seals when fitted and installed correctly are the best there is, (my opinion). I don't know when Mack moved to a lip type seal but I assume in the mid 1970's. My 72 237 still had a lead seal as did my 75 283. Always though it was a neat idea to knurl the slinger grooves into the rear of the crank. Funny thing about that 237 engine is it had so much blowby the road draft tube was clogged by the combination of off road dirt, and oil mist from the engine being worn out. If you removed the oil fill cap from the engine with it idleing, you best have your face out of the trajectory path cause the crankcase pressure would relieve instantly and blow the cap about 20 ft. from the truck. Of course a vented fill cap would have left an oil slick wherever you went. I rebuilt that engine on the back porch of the house and had to have a wrecker come by to slide it into the truck. Rob

Your engine may still have a lead seal in the carrier, but I'm not certain. Rob

Be glad to help you but need more information for diagnosis. Does the unit blow cold air just after being serviced? Does the system lose it's refrigerant charge? Does the binary, or trinary switch actuate shutting the system down. Does the compressor run for a short while then cease? There are many indicators available to drill down to the affected parts or symptom and warm air when should be cold, is to vague. Rob

There is a carrier the seal rides in if memory serves bolted to the rear of the cylinder block. Rob

I posted a yellow one a couple years ago. I'll look for the photo again in my "pile". Rob

Yup. Needs a suppository shoved in so it don't look so constipated. Rob

By all means Happy belated Birthday Barry!! Rob

The "tanning" received wouldn't have been leather on a belt or jacket. Rob

Does not exist. Rob

I've been good for several hours since seeing the post. Rob

In the summer somebody is always turning a tractor over someplace. New, or old, someone's going to get hurt doing what they shouldn't be. Most times it is mowing a ditch with steep inclines, or a waterway where the tractor sinks suddenly and upsets. I don't see a lot of folks use seatbelts in the things either. I righted many of them in ditches and creeks and it's never a pleasure to know someone got hurt. I like rollbars too. However, they do need to fold down for mowing under low hanging branches, (for instance). Certainly makes a tractor more useful when it will fit a multitude of jobs. I kinda cringe when I see someone doing loader work with a row crop tricycle tractor. Seen bunches of them upset cause of turning with a loaded bucket to sharply. Rob

George Bush, Queen Elizabeth, and Vladimir Putin all die and go to hell. While there, they spy a red phone and ask what the phone is for. The devil tells them it is for calling back to Earth. Putin asks to call Russia and talks for 5 minutes. When he was finished the devil informs him that the cost is a million dollars, so Putin writes him a check. Next Queen Elizabeth call England and talks for 30 minutes. When she was finished the devil informs her that cost is 6 million dollars, so Queen Elizabeth writes him a check. Finally George Bush gets his turn and talks for 4 hours. When he was finished the devil informed him that there would be no charge for the call and feel free to call the USA anytime. When Putin hears this he goes ballistic and asks the devil why Bush got to call the USA free. The devil replied, ¨Since Obama became president of the USA, the country has gone to hell, so naturally it's a local call.

Dear Mr. Grim Reaper, So far the past couple years you have taken away my favorite dancer and entertainer Michael Jackson, favorite actor Patrick Swayze, and favorite actress Farrah Fawcett. Just so you know, my favorite politician is Barack Obama. Your Friend
