My house (1790's stone farmhouse) has a Buderus boiler my dad put in in the 1980's that has 2 sets of doors, one for oil and one for coal. It burns about 1,500 gallons a year to run on oil, or I can get away with about 250 gallons for the off-season and 6 tons of coal for the heating season.  The coal is a lot of work, but as a dad of little kids I'm of the opinion that growing up with some more labor intensive chores and maintenance is healthier than the cushy alternative of no responsibilities til they're 30.

I still burn anthracite for heat. Nothing like it in the world. Bulk is $375/ton around here now. Bagged is over $400.

I burn coal too, I believe Keystone Anthracite loaded out of South Tamaqua was $325/ton for chestnut, but I pick it up myself.

I had my inner tire on the right blow the mudflap off the left side of my truck once.  A couple times I've had tires on the right lose their cap and rip the bottom few rungs off a steel ladder that goes up the backside of the truck. The damage a tire will do really depends on the type of failure.

If you're deadset on keeping that truck then look for a donor parts truck with good rails.  For what it's worth, U models use the same frame rails.  We've welded the rails on our R686ST.  Ours are sleeved on the outside, just with a bolt on section.  You're supposed to use 110,000 lb welding rods according to the Mack frame repair book, not 60/70k's as referenced by others.

All wheel drive R models are designated RM600, all wheel drive DM models are designated DMM600 etc.  They're more common in Canada I believe.  Can't speak to who made the front axles.

JoeH,doing it your way the a frames as I call them will stay attached to the frame rails,my way the a frames stay attached to the rears.I’m thinking it may be easier my way.

This style camelback captivates the outside of the frames, lighter camelbacks captivate the inside of the frame rails.  So you'll have to disassemble the cross member to allow the rails to squeeze in away from those massive ears that the frame bolts to.

On this setup I believe the crossmember inside the tandem unbolts I have a truck with this setup, but I've never pulled it apart.  Trunnion bar underneath has bolt on caps underneath, so depending on what you're trying to accomplish you probably have a few options.  You could unbolts the trunnion bar caps and lift the truck off the suspension/tears.  Whatever you're thinking it requires lots of room and big toys to get this job done, everything is heavy!!!

Go to Mack eMedia website, search for shop manual # 8-211.  You can download the book from Mack for free.  It's Engine Brake Output #1.  You have the IEGR engine, not the CEGR engine.

My '95 is only a 350, doesn't have that trans cooler thing.  Dumb question, is it actually plumbed with coolant or has it been bypassed?  Again, I'm sure that's a dumb question.

Coolant drain is a petcock on the lower radiator hose/tube. Approximate location is under the alternator. I assume this is the petcock you're attempting to get coolant out of? 

Some transmissions were tied into the puff limiter I believe. My dad talks about my grandpa's 1981 R686ST that would get a momentary hiss of air when you clicked into 5th gear it'd eliminate whatever torque limiter was in effect and give you balls of power.

I love the bug screen on that radiator, looks built for some serious work.

When they break and Mack doesn't sell the parts anymore what're you gonna do? 🥳🥳

We ran them deleted on our trucks for years. You'll be fine without it.

Correct on reversing relay for the puff limiter, which appears to be disabled. You can pull it off and use that port, be careful you don't break the fitting. You also have another port in the bottom right of the picture it appears.

Tip turbine doesn't make boost, it runs off of excess boost air though.  Use a port on your intake manifold for boost gauge line.

Beautiful matchup, those 2 pictures...

Ok Keystone State!!!!!   why are you looking Blue????   WTF !!!

That was the early/mail in count.  Just gotta be patient and let the districts turn in their vote tallies!  Trump voters prefer in person voting!

Catalpa. We have a few here.
