Seems like 2004 was the start of the "AI" series engine and the EGR problems? Friend has a 2001 E7-427 with a little over 1.2M on the clock and it's been a very good engine without any emissions related failures.

From what I've seen those air compressors such as the original poster has can be troublesome to get a replacement that holds up long. Another friend has replaced his twice since the original went bad at 900K. The first replacement didn't go 50K before pushing oil, and the second replacement about the same. The third replacement is just a few months old and still going from what I understand. All sourced directly from Mack.

Both sides have good ideas.

Exactly. Compromise built this great country, yet so many forget that.

I got one of those too that causes a big black racing stripe on my belly when I drive it!!!

I can't remember as it's been over 30 years for me. I usually send heads in as I really don't have any automotive machine shop contacts any longer.

I have a friend outside of Rochester whom I'll pester to get onto the need. No promises but his brother or some relation was a Mack mechanic for a lot of years when the B series was routinely operated and has a bunch of parts. I'd bet a square cut "O" ring is really all you need to line the inside of the oil shield. With them being shown as separate in the manual, it's usually nothing special molded.

I've only seen the type as shown in the book photo myself. Maybe someone has used non standard parts through the years? Machine shop could probably get something functional as a last resort.

Those are called "oil shields" in the service manual from 1965. I'll check for you tomorrow as it's been a while since they've given me the formal greeting I seemingly command there which is "What the fuck you after asshole"?

Guys here like photos so feel free to post some up.

I remember a couple plow trucks in the St. Louis area as a young guy but wasn't ever around them to ascertain what they series they were. Not surprised yours is a "P" series originally as they were usually designed for a long frame application and most were double framed.

Yes, I'm wanting to convert my 58 B-61 to single drive on air with the 3.65 ratio rear from a tandem Camelback. Going to 22.5 rubber on that one, (staying spokes) but want to use the original single over triplex transmission. The 5.05 rears are just too slow for today's traffic.

Picture is old but truck pretty much looks the same.

That would be my opinion. I would look for a later variant myself like a 300+, (ETAZ673A) or E6-350. and have your injection pump recalibrated to "Maxidyne" settings of which you now have.  Again they are getting scarce but finding individual parts to completely build the platform can be done, but it's kind of expensive.

Again, just my opinion.

Can't tell you as I don't watch any of that garbage either. Actually never heard of "News Max" myself but in reality I have never had cable TV, or anything but a rabbit ears antenna and as of late, a converter box which will receive from the airwaves. I do watch whatever news program is on PBS, but that's not routinely either.

Far too much bias routinely broadcast to the masses to pay much mind to any of it.

Hi Erik, I'm Rob from Farmington, IL about 175 miles SW of you. An RD685P series must have been a platform truck? Seen a few of those as block and cement trucks over the years usually with a long wheelbase and double frame. Heavy series too. What year? You mention in your other thread an E6-237 so early 1980's truck?

Looking for a Mack  Tip Turbine Assembly or any info. E6 237 into a 285 

Not to be discouraging but I think you could purchase a complete engine, (core, or runner) for what all the parts to build one would cost. I've done a couple in the past and it's a great platform for a B-6X series conversion, but good parts are getting hard to come by.

This page is all too funny everything said above about Dems and brainwashing-what the hell do the 

T supporters think has been said about them the last four years. A crazy elitist takes a ride down 

a escalator to announce he's running for president no one pays much attention, then he starts telling

folks what they want to hear and Voila he has a sudden bunch of jim jones followers. Brainwashing?

I seriously doubt that 80% of people who voted for him even investigated him before voting.    

Probably not as they follow the local and national evening news on television:

Forgot to place in the title I'm wanting another 3.65 ratio. I have 3.87 but wanting just a bit faster.

Thanks,

Rob
