Dad drove one of these when he was in the service.Somewhere I still have the manual for it.

This BCR belongs to Al Rhino,a member of our ATHS chapter.I've seen a few on Ebay in the past,also.

the EM6 was a Maxidyne version of the Econdyne E6.It was a low rpm engine.Your truck might have had a different hood put on it or someone might have just stuck the emblem on.I've seen both EM6 and E6 300's with 5 speeds.

The good ones are made by Lund and you should be able to get them through any Mack dealer.JC Whitney even had them listed in their catalog at one time.

Too make things very simple,the biggest difference between the early Maxidyne 300,300+,and early 350 and the E6 engines was the aftercooling,the early ones used the side mounted aftercooler and a tip turbine fan,E6's were air to air mounted in front of radiator.I believe your 2nd pic is a 678 (early 350),not an E6.

The difference between a ENDT676 and a ENDTB676 is the B means it has a Dynatard engine brake.Dynatard's require a special cam and can't just be added to any engine without changing the cam also,were a Jacobs Brake doesn't need to.

Tim,

I have several old Mack wrenches and tools.Most of them I have were made by either Williams or Bonney.From what I've heard,the came in tool kits with new trucks back in the 20's&'30's

Thanks for the pics.Always thought one of those H-81's would make an awesome wrecker.There was a story in Double Clutch awhile back about a couple of them getting saved,think Dave Zsido & Bob Giddings got them.

I was told that the H-81 was built to use up a large quanity of day cab H cabs Mack had ready for a large UPS order that was canceled when the F model came out.Don't know if that was true or not,but makes for some intersting history.

Wish I had one of those in my back yard.I've seen twin steer F800's,but never a F900.You wouldn't happen to have any pics or know where there is any H-81's do you?They were used in NYC for heavy mixers too.

It means that it wasn't a completely brand new manufactured truck.Glider kits were a new cab,frame and front axle.The idea behind them was that it was a way to rebuild wrecks or update an older truck,by using the still usable engine,trans.,and rear axle & suspension.For awhile,Mack even offered powered glider kits.These were new cab,frame,and front axle,with a factory reman engine installed,you just had to put in the trans. and rears.

Tom,

Do to the price of fuel,I didn't get to round up any stray B's this year,just a crusty A54 and a C609.Hopefully '06 will be a better year cause I'm suffering from withdrawal really,really bad.

Keep up the good work.

If you decide thats what you want to try,I've got a gutted '82 R model I'd trade or sell you cheap.The steering box,column,linkage,etc. is all there.I think I even have the p/s resevoir for it.You'd just have to come up with a p/s pump to fit your 220.

I've never seen one up close or in person,but I've heard of using an R model steering box and steering column.Takes some modifcation,but it works.

worst part about leaving the starter of the top left is that it makes it a bitch to change if it ever goes bad.

F models had the same set up,so that should broaden your search options.

There was an E9 on Ebay recently,don't think it sold.You might look there to see if its still on.

Their were 2686 ED's built from 38 to 44.They are not Mack Jr's.The Jr. was built by REO under a marketing agreement with Mack.The ED was a true Mack.

How about posting some pics of the F715,Brad?

Hey guys,

    Don't forget the Megadyne!!! They had those too!

It was Magnadyne,these were flathead 6 gassers.

keep an eye on Ebay,there's been a set on there off and on from the same seller,don't know if it was the same set that never sold or he had more than one set.the seller's ID is kingofsalvage if you want to search that.

The very early B73's,B75's,etc. had the sheet metal radiator shell and smaller radiator.They went to the large cast aluminum radiator sometime in '57.

I remember when Overnite Transportation was selling off all their old MB607T's,some of them were in the '70's.If I remember right,they were rated at 187 hp.

The ones that had the one piece windshield were the first produced.Wasn't many of them made.

That didn't quite work like I thought it would,but at least the pics showed up.I also have a '54 B61 with Page&Page,it's pretty much the same set up except it's a single drive axle with pusher axle.

Here you go,Fred.

There was a total of 4974 Mack Jr.s built from the 1M half ton to the 31M 3 ton.There were also 2 COE models the 21MT and 31MT and a bus chassis model 91MT.The Jr's were only built 2 years '36 and '37.
