Mack rears. 3:87 ratio. I've been told that 3:87's and 3:65's are weak gear sets and that I need to replace with 3:86's because they have more meat on the gears. I also just put a new set of drive tires on a few months ago, noise started shortly there after. Seems like the last time I changed drive tires I had a rear/rear go bad.

We did check the height. It was out about 3/8 of an inch. Is that enough to cause damage? Now that the height is correct the growl is worse. Should I be looking at the tranny?

Been having a growl noise coming through the trans almost like the noise one makes when you accidentally run with the airbags deflated. We jacked it up today and ran it with the wheels off the ground. The rear/rear makes more noise than the front. Pulled the side cover off but no smoking gun. No gears messed up, not a lot of excess metal. Ran it again. Took it up to 70 mph on the jack stands. Checked the temps with a heat gun. Front/rear 103-105, rear/rear 123-125. Only ran it about 5-10 minutes. Is this temp differnce normal, or is that my smoking gun?

Thanks 84superdog. It was great to meet Staxx at Nashville. Wish I had more time to hang out there the other day. I hope he gets the E9 headers worked out he was talking about because I want some!!!

Yes it is. Had to explain to the wife yesterday at 6am when the emergency call came in that TRUCKIN AIN'T A JOB IT'S A WAY OF LIFE!! When you got a friend broke down you saddle up and go get him.

Had to go get my friend's CL with an E9 yesterday. He broke down in TN on I40 at the 311 mm. Think its got a gauld piston on or bad bearing on #7 or #8. Hope the crank ain't messes up.

Thunderdog, has your E9 had any fuel turned to it? If not a good bolt on replacement for the stock turbo is a Aussi 610 turbo. I can't rember the whole part # but I know the last four digits are 5134. I think the part # is 631GC5134. This is a good turbo for a stock 500 E9, but if your gonna turn the fuel to it or put some hot injectors in it don't run it. It will cause high pyro temps and high water temps. I know from experience.

I have to repeat the sentiment, if a MP 10 is walking all over your E9 somethings wrong!!!

Here are a few pics of my boys a few years ago at the N&S museum in Roanoke with the 611 and 1218.

I LOVE THAT! Thats impressive! Reckon how many diesel would have taken to pull that same train?

You must be the bestest/fastest camera man in the east to snap that pic of the MH. I've tried it and it ain't easy.

Maybe this pic will show the DM chassis a little better

I had more time today to play with the computer and post these pics right. Hope ya'll can enjoy them a little better. The DM does have the pot belly chassis, my pic just doesn't show it very well. There are several sets of Mack boggies sitting around. Hope ya'll can open the pic of the 78 R model. It was the first thing I noticed when I pulled in the guys yard. He asked me if that truck looked familiar. It was one of my dad's old R's he bought back in the late 80's. It came out of the Texas oil fields. Dad sold it to a local logger and this fellow bought it from him. This is for Brocky. The man's name is Dale Lawson but I don't have any contact info on him. All I know is he lives in Pauline, SC. Mr. Lawson said he still has the U model with the 865 V8 over at another farm. He said his dream was to restore the DM one day.

Hope this works. I'm not very computer literate. I delivered a load just south of Spartanburg SC today and found some cool old stuff sitting in the woods. Check out the DM with the tree growing up between the frame rails. It has a set of 52 or 54 rears. Found the hood sitting down the way with another hood the owner says is for a U model. Check out the V8 emblem on it. The GMC Astro has a 318. I think the White is a 8000 or 9000. The hood emblem just said White Diesel. The F model is a single axle. The roll off cabover is a Mack but I'm not sure of the model, but it has 44 rears. I'm not sure of the model on the IH truck or the Dodge. lawson equip.zip

I just experienced the same problem. I had to change AM/FM tuner a few weeks ago. The old one was 12 years old and finally just gave up. Ever since I installed the new tuner my CB bleeds through on the speakers and I cannot pick up any AM/FM stations but the Sirius satelite part works fine. If I hit the mute button on the radio before I talk on the CB it does not bleed through. I have not been able to correct my problems either.

Plenty of old Macks down there. Look up Randall Howell in Ball Ground, GA or Jerry Turpine in Hiawassee, GA. Both ATHS members and Mack fans. If your passing thru SC on I 85 I'm in Blacksburg, SC (right on the NC/SC border) give me a call and if I'm in town I'll treat you to lunch. 803-984-0696.

Logtruckman I had a simmilar experience around here.. I used to pull lumber out of South Carolina up to east Tennessee and then reload with brick or cinder blocks and come back. There was a guy with a Western Star with a 475 Cat and 13 spd that made the same run. After I blistered him a few times on Sam's Gap (the mountain on I26 at the NC/TN line) he traded for a Lowmax Western Star with a 550 Cat and 18 spd. I smoked that one as well and he finally quit trying.

I've been approached by more people in the last year than I ever have wanting to buy my Superliner E9. I just tell them no because there is nothing out there today that will replace it or even come close to it. There next question is where can I get one. I just wish they had showed intrest in E9's when they were in production, maybe we could still get one today. The funny thing is most of these guys are driving Cat powered Pete's and KW's.

My dad had a 83 Superliner with a E9 440. He was going west on I 26 in Hendersonville, NC just leaving the scale house grossing 80k with a load of lumber. Two empty cabover IH's pulling flatbeds took the bypass lane and tried to pass Daddy while he was building his speed back up. Needless to say they couldn't get it done and had to fall back in line.

I'm no expert on the subject but I'll tell ya what I know. The alt is 12 volts but has a transformer on the back that increased the voltage up to 24. 24 volts goes into the two batteries on the right (passenger side) and 12 volts is trickeled down to the two batteries on the left. If you check the voltage with a voltmeter on the batteries on the right you will get a 12 volt reading at the posts, but because of the negative ground system you have to ground straight to the frame and there is where you get 24. When I jump start other equipment with my 1990 Superliner I alway jump start from the right side, one cable on the positive post the other straight to the frame for 24 volts of juice.

Factory specs call for a 16/26 adjustment but I have been adjusting mine at 14/24. This just helps the adjustment last longer as well as keeps the hide on your kunckles.
