When I first got my 611, I put in fresh fuel and filters. It still didn’t sound exactly “right”. I had been adding a little 2-stroke oil to the ULSD fuel. I got a jug of Opti-Lube XPD, and dosed it on the next fuel stop. Within a half mile, it smoothed-up. And the idle went up 50 RPM. Probably the injector cleaner in the XPD. Made a real difference. You’ll get it sorted out. I have no doubt

The Mack just always felt “normal” to me. Never had an issue with snEaton, though. Of course, all my Mack experiences had 2 sticks!

That's my biggest gripe with all the new "eco-friendly" crap, whether it be a lawn mower or a new truck. The best way to protect the environment, in my opinion, is to make stuff LAST A LONG TIME. When you have to make new crap because the old crap melts down, there is a much bigger footprint to that than most people know. You have to dispose of the old crap, mine new materials for the new crap, ship the materials for the new crap, manufacture the new crap, package the new crap, ship the new crap. It goes on and on. But, I digress. Rats...they got sharp tails.

Double-Clutch, Float, whatever! Still have to do it right! I'm just glad he didn't have to start spending money on that thing!

Oh no! Don't tell me we were trying to learn how to double-clutch that one! LOL! Glad you figured it out!

Yep. If it's a 24V starter, pretty much need 2 12V batteries! And, like you said, the wiring and Series/Parallel switch has to be good. I have wired 2 12V batteries in series using jumper cables to test a 24V starter before. That starter spun fine. Ended up being the wiring going to the starter on that one.

It couldn't possibly hurt...

Like this ring, right here???

One thing I learned about Macks, back when I was a little guy riding around with Dad, is that a lot of the minor parts could be bought at a hardware store! Later, when I was trying to keep mine up, I fixed as many things from the local hardware store as I did from the parts store. They did a really good job of using "common" parts that were easily sourced. I remember, at one time, the ignition switches were from Briggs & Stratton. Makes Mowerman's avatar even more appropriate, doesn't it?

Sent a message. Got no reply. I'm moving on...

First thing I did on mine was replace every air line on it, the slack adjusters, and the brake chambers. Got rid of the rotten hoses on the frame and replaced with DOT air line tubing. After that, I felt a lot more comfortable driving it! With all the collective knowledge of the guys on here (you know who you are!), there's not much you can't find out on this forum. Keep posting pictures! We love pictures!

Pans are a “deep draw” product. The metal can pull extremely thin during the manufacturing process. That is a common cause of cracks in the thin areas.

Yeah, I got through to Jeff earlier too. I see he already got back with us with an update. Classy guy.

Still dead. I don't have personal emails for any of the guys over there. Maybe some of you can contact Jeff? Hope everybody is okay over there.

I have a friend in Mentor. Runs a tool and die shop. He makes all of my custom cutting tools and bars. Takes my mental nightmares and turns them into reality.

I suspect the splayed shape of the rails would give most people fits.

The R611 I drove for Shuler had the 24V starter on it. Had a push-button to engage the starter. It was basically a manual relay that put the 12 volts from each side in series to the starter. The one thing I will say is this...it would ALWAYS spin the motor over! Even when the batteries were low, it still had enough power to turn that pig over on the coldest days. Of course, my more-recent R611 had the basic 12V setup, and I never had more than one 12V battery in it. And it did fine too. Only saw a couple of really cold mornings where it said it hated me. But, plugging in the block heater allowed us to come to an understanding, and away it would go! And, yes, air start is still cool!

Rats. They've got sharp tails. Or... SQUIRREL!!!

I'll try to see if I can find it and put some more info on here, time (and The Boss Lady) permitting!

I seem to remember seeing those, too. Made sense to me!

That's where I'm at. Not sure where that truck is. Will have to investigate.

True. Definitely something other than "Bulldog Enthusiasts".

I have airline schematics, too. Not sure what kind of parking brake setup you have on there. Mine came with DD3 brake units. Very complicated system with extra air tank and an "inversion valve" (see pictures). I swapped it over to regular spring brake chambers, which was very easy. It also eliminated a bunch of hoses and stuff. Worked better, too.

They are actually fairly easy to work on. Very well designed beasts. The biggest issue I saw when one was changed to negative ground was that some of the gauges would not work correctly. For instance, I had to change the volt meter on mine, because it was not possible to reverse the gauge (single wire, ground through case). Had to get a 2-terminal gauge so I could connect the wires to the terminals with the correct polarity. Also, I think the fuel gauges did not like being reversed. But, I am fuzzy on that one. Light bulbs do not care. Nothin at all wrong with positive ground. Just have to isolate any add-ons that you have (like radios or phone chargers).

I don't understand all the "hot girls" that showed up on here for one day. Of course, those pictures may not be of them! Might have actually been a 400-pound guy living in his mom's basement for all we know!
