Well it is up to $19,500 with 10 hours left. It may bring more than I predicted..!!

I own a 500HP that I bought new in '89. I friended a man in PA who worked for Mack. In phone conversations with him about my E9, he claimed that they were sent to Canada making 600HP and shipped to Australia making 800HP..! Strictly hearsay I know. It was interesting food for thought.!

Well it is up to $5750 right now with the biggest jumps to take place right at closing. I was really considering goin' for it, so I did some research. The VIN reveals a 6.73:1 rear ratio. Even with the tall 24" rubber, cruisin' at 1900 RPM, this truck would top out at 40 MPH assuming it is not an OD transmission..!! What a long trip to TN..!! Having it hauled would be my only option, which I feel rules it out..! Would make a helluva dump truck.!

Here is a pic of the McCord 761 that Tackaberrys now own. This was taken before the red paint was applied. It spent most of its' life yellow and black.

I predict it will go for over $30K with the 10% buyer's premium.

My Superliner. '89 E9-500 RTX15715 44K. I was picking up a winter project from McCords in Nashville. This lowboy is one of several that Buford McCord built himself.

. I would definitely take the 24's off the front and they would be replaced with something fat and tubeless. I'm sure it would require a hub change. The rears would stay.

I agree about the 24's. They'd have to go..!! Looks like it has sit thru a bunch of California dust storms with the windows down.!

Do you mean you can't click on my link or you can't find the site for local government agencies to acquire US surplus? If the latter, it is too late for this truck, I think..! It is already listed to sell to the highest bidder and I predict it will go pretty high.!!

Looks like it has 44K rears. Tell us how it is spec'd out. Love me some R Model Macks..!!

This is my 84 year old Mom trading her '98 F-150 for a '13. We like our red Fords..!!

Damn I wish this one was closer to me. Here is a link to Gov. Liquidators. Truck is showing 10K miles.! Looks like 56k rears. http://www.govliquidation.com/auction/view?auctionId=8360623&convertTo=USD

Took this picture at our house this spring.! Sis'n'law, son'n'law and mine.!

Would bet a stack of dollar bills you lost a spacer or shims when the carrier bearing dropped. Start stacking some washers between the carrier bearing and its' mount till the vibration goes away then fab a plate spacer this thickness for your permanent fix. OR. Go to Mack Parts to see if they show spacers for your truck. Could show a specific spacer. If the list shows shims "as needed", then you're back to experimenting with washers.

Ok...my head is hurting.... let's move on to u-joints or compression ratios or the effective ground pressure (in PSI) differences between 425 and 385 floaters when used on a steering axle..!! JUST KIDDING...!!

:)Just because I like math ! If the fourth gear reduction is 1.24:1 like the 15 spd direct quoted above, let's just throw a tooth count out there to play with: 40 teeth driven by 32 teeth is 1.25:1 ratio. Flip those two gears, 32 teeth driven by 40 teeth is 0.8:1 which is pretty durn close to factory OD ratios..!

Not that everyone here does not already know this, but there could be others reading all this with a big question mark hanging over their heads..!! Basics: a "direct" drive designated transmission means the engine crankshaft turns over one time, the driveshaft turns over one time when the transmission is in "high". An overdrive transmission is capable of turning the driveshaft faster than the engine crankshaft when in high gear. An RT910 can easily be made into a "homemade" RTO910 by flipping the 4th gear gearset in the main box. The reduction ratio of the gearset in the 4th stick position (I use "stick position" hoping everyone knows what I mean.!) when flipped around (the larger gear becomes the drive not the driven) becomes the overdrive ratio when the stick is in the 4th stick position. The 5th stick position remains "direct" or 1:1. The unsavory "gap" is after you shift thru the first three gears (range selector in high or low doesn't matter), the stick moves over and back to the 5th stick position essentially skipping what used to be the reduction ratio of 4th, then the final move is the stick going forward to the 4th stick position which has now become an overdrive ratio by flipping that one gearset on the shafts.! That was the explanation given to me 30 years ago by a transmission guy. I have never done this but did consider it years ago.

BINGO...!! We have a winner..! My Superdog has an RTX15715 (X denotes std. shift pattern, single OD). When shaking a heavy load, I run thru all 5 stick positions in "deep", then shift back up to the 4th stick position simultaneously flipping the deep button which gets it ready for two gears in the low side of the range selector. Then shift the range selector to high for the remaining 5 gears. This yields a total of 12 perfectly spaced ratios with no duplicates. This method will gain the most ground speed before an air shift takes place.

With an engine RPM of 2100 turning an OD ratio of .62:1 , the driveshaft is turning 3387 RPM..! That's hummin'...! The Spicer document that j Hancock linked for us is an excellent read. The tailshaft centerline of the trans must be parallel to the input shaft centerline on differential. I found a vibration once because this alignment was wrong. Had to shim the carrier bearing for the fix.

Here are a few pics of my permanent solution to transformer failure. This is easily done and can be returned to "factory built" with very little effort. I used grade 8 studs to replace the air compressor cyl head bolts to mount the bracket. Put a double pulley on the main 12V alternator to drive the self-energizing 24V auxiliary alternator. The 24V wire from the transformer is connected to the aux alternator.......Transformer trouble GOODBYE...!!

That is a great setup. My first new Mack was a 1980 R model w/350, 8LL RdRgr, 44 rears. I loved that truck. Somebody else loved it enough to steal it in Dec of 1988.! Very cool that you guys have the Superliner home.

My Dad purchased this truck new in 1987. What are the specs on this truck..!

Pretty sure you got the same setup as my '89 E9. That box is a transformer which takes 12 volts from the alternator and turns it into 24 volts to charge the two batteries that are used during start up. After buying four transformers ($300 a pop!) over the first 15 years of owning my truck, I had to do something.!! My fix was to install a second alternator. A Delco 24 volt, single wire, self-energizing model was used. I fabricated brackets for the install. 10 years of trouble free service so far. I will post pics for you tomorrow.

Please do post it..! That is cool.! Shorty and I had tentative plans to make the trip up there, then it dawned on me that since I was running for a County Commissioner's seat (I did win)and the election was on the 7th, I just could not leave town.
