the drive shaft has to have phase angles set you might need to check them jump on to google theres plenty of information the one that I dont see is when you have more than on drive shaft in a row the uni's should not be in a straight line as they interfear with each other they should be set lagging behind the front shaft one tooth as you are coming back from the transmission have had this cause problems for me in the past

as to the other part of the question the drive shaft not vibrate at all no matter whats speed oh and make sure the big bolt in the gear box yoke is tight this has also caused me grief before

So are you saying the driveshaft should be one tooth off in the slip joint? Thanks for the response gentlemen

Ride height has been a sore subject. I have called several folks including the people who took over Neway and received several different answers. Experimiting has been the best help.

What? Where are the N.H. cabovers? Barney has let few people drive his 81 R model 300 6 spd. The only Mack around that is slower going to Pa than mine. Truck is in very nice shape.

Truck has Mack 6 spd with a .62 overdrive. CRD 92 rears 5.73 ratio. truck has Neway susp I have been chasing this vibration for some time. I know what I should do is change tranny and rears to slow down drive shaft rpm. I have been told that I will never get rid of all the vibration due to the incredible shaft rpm. What im asking is this true? I have replaced all U joints, Slip joints. There is a little movement in output yoke in front drive. Any ideas short of better ratio and tranny?

LOL. I was going to say How rare? We have 2 B61 integrals in the yard.

If your doing a Superliner im afraid im no help to you. I could dig the part number for the condenser that I used but I don't know if you have the same set up.

Mine is a WS like in the pic at beginning of this thread.

UNBELIVEABLE!!!!! Nice job. And you didn't get cocky with the officer like he started to do with you. Good for you

I can send you a phone pic if you like. I used a condenser for a Mack RD. I had to drill and tap the radiator frame and add a 3 in piece to the left side to mount it. The good thing is its in front of the fan so the air is pulled thru it.

If you have the AATAC you fit a condenser between the grill and radiator. Ok, here we go. Get your pen and paper. I fixed the stock A.C. but had to cut hole in dash cover in order to get enough air into cab. If the rear A.C. was hooked up it would freeze you out. As it stands its ok. Remember when I asked you for dash pieces? So I know you have the correct parts. Why is your bunk unit in the left side? Ive had 3 Cruiseliners and all bunk unit were in right side. The evaporator is avialiable here thru a local guy. I replaced just about everything in there. The reason I could not hook rear unit was the only condenser that would fit isn't big enough to handle 2 units. There is very little room under the AATAC and bottom of grill. Also I use R12 Freon because it cools better in the old systems. Hey were 80's all the right down to my 1987 Alpine stereo casset ! LOL. Also keep inmind when doing a condenser when you have air ride cab the grill moves but not the radiator

That "standup" F model is a 300 5 speed low mile truck. When the previous owner called me we had quite a chat. That was 6 years ago. Nice truck

4 pounds sounds excessive. I think with a bunk unit they only hold @ 3 1/2 pounds at best.

I absolutely agree. I will start with testing the injectors.

Hmm.

LOL. Try getting parts for older "first generation" John Deere's. You see, JD had the foresight to "reuse" older model numbers. Try explaining that to a 25 year old parts guy. Yes JD did make a 5020 back in the 60's. A GOOD PARTS PERSON IS WORTH THEIR WEIGHT IN GOLD!!!!!!!!!!!!!!!

Thank you Gentlemen. I did not know that a weak injector could cause that. I was thinking governor or something else in the pump.

Hmm. Intresting. Lately I have noticed It sounds odd until it warms up. Guess ill price some injectors & hope that cures it. If not looking at the pump. Thank you.

Now that I have my A.C. working its nice to take a nap in the cold air sometimes. Problem is, the engine RPM changes around 250 RPM no matter what throttle I set it at. I like to set throttle at @ 850 or 900 Kind of annoying. Its an 83 E9 with the AMBOSCH V pump. Any ideas on how to stop this?

That's what I did with my 6 spd. Stood it on its bellhousing. Also, Some of the forks have to be held in place with wire, coathanger while linging the fork shafts up to put back together. Good luck, hope it goes well for you

That's interesting. A 2 wide 4 deep sleeper

Would it make a difference it has a unit in the bunk? that might add more oil

Thanks

You do come up with some interesting trucks. Nice

I think youre adjustment is the bolt in the front of 5th wheel.

If your tank was low when you put fuel in it may have "drawn" the fuel away from the pick up tube. Once the pickup tube sucked air Detroits can be real mean to bleed. Not saying that was your case but worth looking into
