39 Baby Mack

Happy Birthday!! Ron

Here's a link to Antique Automobile Radios in FL.-------- they sell a power inverter that will do what you want it to do. www.radiosforoldcars.com/power.htm You can use one of these and not worry about insulating the radio or antenna. Ron

Use to do this many times for guys at our place. You have to mount the radio in a box or with rubber to keep it insulated from the chassis ground. Then just hook the ground of the truck which is positive to the red (pos.) lead on the radio and the hot side of the truck which is negative to the black (neg.) lead on the radio. You also have to insulate the antenna from chassis ground because it also feeds ground back to the radio through the coax cable. A radio guy told me one time to cut the ground in the coax cable and install a resistor in line with it and you wouldn't need to insulate the antenna. also this would not affect the ground plane of the antenna and make it work much better which it did. Unfortunately I can't remember the value of the resistor. Maybe someone else can help you with the resistor value you would need for this. There our also many people that sell power inverters for antiques which would also probably do the job although they are as a rule a little on the pricey side. Ron

Happy Birthday Rob Hope you have a nice day! Ron

Sorry 57 BCR couldn't remember the hours for sure and didn't feel like looking for my brochure. Ron

Sort of...... Didn't come with frame rails, radiator, or front axle. Just cosmetic changes. Ron

Ken This was a special kit sold by the Mack Co. in the late sixties, so you could take a tired old "B" model and upgrade your truck to a new style "R" model. The brochure showed pictures of before and after of an old "B" model. An inexpensive way to upgrade your old truck. Brochure stated that you could go from the "B" to the "R" in something like 40 hours!! Ron

Leslie It's a four valve, aluminum valve covers. injectors are internal (under the the valve covers), injection lines go into the head on R.H. side above exhaust manifold. Ron

Looks neat Vinny! Listen to your mom, we'd all like to see you in one piece at Macungie!!! Ron

Thanks Vlad! Ron

Wonder what's with the cab on the "E" model------it has a two piece windshield!!? Ron

Happy Birthday Paul! Ron

Sorry Mike That's not the same trailer, this is #T-98 also a Highway but was stretched to a 40' nine horse trailer and was converted to air ride with tandem axles and 15" wheels. There were originally five of these trailers, #'s T-91,T-92,T-93,T-94(which Mike now owns) and T-98. #T-93 and # T-94 remained six horse trailers all there life. I think they were 32' to start with. #T-93 remained painted cream and red it's entire life. #T-92 and #T-98 were stretched to 40' nine horse trailers and converted to air ride with tandem axles and 15" wheels. #T-98 remained painted cream and red it's entire life. And believe it or not #T-91 was stretched twice during it's lifetime first to 40' to make it a nine horse trailer and then to 45' to make it a twelve horse trailer! Ron

I'm usually pretty fussy about who washes my little blue Baby Mack but I think I'd give them a shot at it!! Ron

You beat me to it!! Ron

Ken It was probably removed because later Macks with E.S.I. (extended service interval) systems didn't use the filter but were just chemically treated. So they most likely upgraded the vehicle and removed the water filter. Ron

Mark I know, leave it to me, but did you or anyone else notice he's driving barefoot or at least his right foot is!!! Ron

He has a point there, the early "MH"'s had the astro- turf style on them too. We used to haul horses and when we left Belmont Park I swear we'd bring half the mud home from the stable area!! Ron

BP Are you sure it's an "A" model, chassis # is for an "EQ"? Ron

That's one pretty "R" model!! Ron

This probably is normal We had '86 & '87 CS300's with Knorr air compressors which are not equipped with unloading valves, they govern the pressure in the brake system by having the excess air exit through the purge valve on the air dryer when the governor cuts out. Ron

Does the tree come with it? Ron

Ken The housing on our "MH"'s were straight, the areoquip line would certainly work but there isn't much room to route it where it has to go. The line goes to the R.H. side of the block all the way in the front behind where the water pump housing bolts to the block. You should see a 1/8" N.P.T. pipe plug in the block where the fitting should go. Originally there was a 90 degree fitting there pointing upward and as I said before it used the old compression fittings with rubber ferrules as was used in the old fuel return lines. you need a 90 degree connector for the block and a straight connector for the water filter head. Ron

Happy Birthday Mark!! Ron

Ken I used to make the tubes out of 1/4" steel brake tubing when they needed to be replaced. Looking at the picture I don't think you need a new thermostat housing, looks as if if Martin's or someone just tapped and plugged the water hole in the housing. Remove it. You would just need the adapter, fittings w/ rubber ferrules (like old leak off line fittings), and check valve w/"O"ring. You would also need a couple of longer (I believe they were 8mm bolts) to mount the adapter. That and a Baldwin #BW5176 plain filter or #BW5178 treated filter and you should be good to go. Ron
