My '48 Int. KB-7 (Sanford)
Joey Mack replied to Joey Mack's topic in Antique and Classic Mack Trucks General Discussion
I dropped the oil pan. 1/2'' of sludges, probably why the oil pressure was low, the pick up made a dent in the sluge.. I blasted the pan but old age reveals some small pitting on the outside. I'm good with it. Primed and painted it and the bolts. -
My '48 Int. KB-7 (Sanford)
Joey Mack replied to Joey Mack's topic in Antique and Classic Mack Trucks General Discussion
I took a closer look at my starter. Yes the old coils had 2 screws to attach to 2 brushes. But those 2 brushes have a jumper wire. Now I'm thinking I can use what I bought because of the jumper. those 2 brushes are 180 degrees from each other. -
1994 mach ch613 Air suspension won’t deflate
Joey Mack replied to IDumpMack's topic in Driveline and Suspension
I expect his to be air over air dump system, with a QR-1 valve after the protection valve, and piloted by an air switch. - Today

So there is something that happend when these first came out I will mention! Disconnect the alternator for awhile and see if the issue goes away! The ecm is vulnerable to Voltage spikes If the alt is spiking the engine will shut down! just a thing to check for! We had one that did this very thing! We sent a service asist to Mack! They were able to duplicate the issue on a dyno for us! They also found it by accident The teck spotted it out of the corner of his eye while running it up! real far out there fix but shit happens! check the alt connections ect! Something to try!

Well, my visit to the DMV this morning did not result in a registration but they explained what the issue is. She was all set to give me Classic plates but when she entered the GVWR (24000lb) into the computer it required her to enter DOT number in order to proceed. I explained that a DOT number is only required for commercial use, to which she agreed, but the computer would not let anything proceed. They said I need to get a DOT exemption from the state, requirements are attached. With this notarized letter they could override the computer and issue me Classic plates without entering at DOT number. I don't know what the GVWR cutoff is that triggers that requirement, but I would preemptively request the DOT exemption before you show up to your DMV appointment in the future. It says it will take up to 7 business days to get my exemption processed. Also, they asked if I would like a new title. I was surprised, and said I didn't think the state issued titles for vehicles over 20 years old. She said I can request a title at time of registration, it costs $25 extra. I think this is cheap insurance for if/when you sell, making it much easier to sell to an out-of-state buyer who may need a title for their state. When I left, she thanked me for being polite and understanding. Having all your documentation organized, knowing the requirements, and being polite puts you ahead of 90% of the people who walk into there.

finally some superliner progress
Mack_man replied to Mack_man's topic in Antique and Classic Mack Trucks General Discussion
I’m not going to be able to do all of that in a weekend -
Nice expanding Bmt

Got curious so looked it up, according to my manual for the 1973, slippery road reduces the pressure to the steer brakes by 50% , so a 30 psi at the treadle would result in 15 psi at the front brake chambers.
-
I checked it too
-
Although I don’t know if I can call it cheap shit at 5:45 a gallon ha ha
-
I’ve never had a problem with my V6 Mustang. It runs like a champ on the cheap shit.
-
You know I don’t know if we sell it here or not I usually just get the cheap shit but there’s ordinarily three choices on the pump. I’ve never even noticed what they are now I’ll have to look out of curiosity.
-
But I have to admit I’ve only been sick one time since then I picked up some crud that hung on for a couple of months. I finally wound up going to the doctor for antibiotics to get rid of it. I don’t know what it was. That was about eight years ago. We are just got back from a trip to San Diego and Disneyland so I’m sure I picked it up somewhere down at the park.
-
I never got them either till my company was offering them right in our break room nurses would show up and give them with free donuts…. After I few years I said oh well what the hell …. But originally I stay far away from sick people anyway

The wet/dry road didn't "kill" the front brakes, it reduced the pressure provided to the front by a percent of brake pressure in the system. I don't remember the exact percent, but my '73 and '69 had the manual valve on the dash and a "ratio" valve before the front brakes. Modern trucks have the same thing but is automatic will provide full pressure if the brake pressure rises above a set pressure (60 psi?) and on lighter braking reduces brake pressure to the steer. That is different from when no steer axle brakes, where brakes were not fitted on the hub. Driving a bobtail tractor with no front brakes on the axle on slick roads is a real pucker factor experience. Over the years different things were tried to address the front brake issue. Before the dry/slick manual controlled valve, smaller chambers on the steer (today type 20 is the most common) but that limited braking on dry roads. No front brakes, Larger chambers and either driver selected or automatic limiting pressure were tried. Today automatic reducing valve and large chambers are what is used to meet braking stopping distance requirements, where standards dictate stopping distance loaded and loaded with 1/2 the system inop. Front brakes that can deliver maximum braking force on the steer are the only way to meet these requirements.

lol I pretty much forgot about those ,,, my DM actually has one … speaking of dummy’s I heard years ago someone said something happened to everyone around middle 60s when people started getting stupid ..college people now have IQ of high school graduates of 1960 … sorry off subject…. Bob
