    • I'm rebuilding '59 B46 and have some brake questions. Brake chamber sizes: I have Type 12 on the front (5-11/16" dia.) and Type 30 on the rear (8-1/8"). Is this a common configuration? The rear chambers are mounted on two different cast brackets - one cast iron, one cast alum. They are different shapes. I'd like to replace the right (alum) to match the left (iron). Or... There are chamber brackets welded to the differential. Looks like I'd need a lot of parts ($$$) to move the chambers to these bracket.  And ... some additional photos.

    • Timber Jack I don't know how to search the archives to find the threads but I'll tell you how I cured the identical problem on a 2004 460 that I bought new.   At about 150,000 miles it started puking coolant like yours is doing.  I replaced screens, thermostats, and even the radiator and all hoses to no avail.  Problem got worse instead of better. I fought it 2 years or so. In desperation for my last shot I went to the bone yard and got a large capacity single compartment aluminum reservoir tank and replaced the original 2 tank Mack set up. I only fill the reservoir to half full and replaced the radiator cap with a 10 pound cap instead of the 16 pound that was recommended. Over 1 millions miles later he has never puked coolant again after the switched reservoir. The stories should be archived here written by JerryB and begun.

      As usual Teamster Grrrl,your points are well taken! While I agree in principle with many of Trumps "promises" most are half campaign rhetoric and the other half monetarily and politically impractical! While I would prefer a utopian world where all immigrants entered America like KSBs wife and many others in a legal manner,we are stuck with many who have been here for years that didn't.we don't have space in our overcrowded jails,or the money to deport the others! So give the ones who have no felonies a pass and have them report to processing centers and get an I'd card that will make them legal to work till they become citizens.Have them report annually until they become citizens with instant deportation the penalty for not reporting on time! Find the money and personnel to deport the criminals! Having said this establish a date for these procedures and deport anyone still here who doesn't comply! I suspect that most of those who are here illegally would be happy to begin life "out of the shadows" and work towards citizenship! After the established date Double the personnel and efforts to deport any new illegals and make all new prospective citizens go thru the previous procedure to become citizens!Yeah, I know it isn't fair, but neither is life! Also find a way to make Mexico help police our borders maybe a head fine on illegals! Or a tax on Mexican companies profits on the products they export here! Bet the companies wouldn't be as easy as we are on their " fellow citizens" if it affected their profits!

      Hi!  We have a CTP 713 B with mp 7.  Truck quits running three miles from shop, once a week. The dealer diagnosed and replaced the oil sensor level. The truck went three miles and quit again. The turbo codes have tripped as well. Any ideas, help, thoughts greatly appreciated!  Truck has 300,000 miles on it and runs great when it is running. Thank you.

      Mike, while you are looking for a proper horn button if you can find the horn relay you could run a separate wire off it to something hot under the dash with an accessory  fuse to one of those old fashioned horn buttons they are still sold in parts stores.Just find a place to mount it that's accessible but doesn't screw up the dash!

      Happy birthday DCR! Ever wonder how you got that old? I do every  day! I'm always amazed how cheap retired fire trucks go for! An 87 Ford f 700 with 16000mi 3208 cat With a straight 6speed from a local retirement community's volunteer dept listed at 8700$ admittedly a non purpose built c/c,but not broken in at that mileage! Wouldn't hazard a guess at what it sold for new!Almost certainly could be had for any reasonable offer!
