So you can look good coming in on a wrecker????? Sorry, old habits die hard.....

Agree with this. Always like a "single stack in the back" and usually on the passenger side to stay away from the noise myself.

No. It will be stamped into the axle beam itself below or very near the spring seat and viewed from the front of the truck looking rearward. It could be a faint, or light stamping and may take a wire brush or wheel to reveal it. I have never seen an axle that was not stamped unless it was a Rockwell/Meritor, or sometimes Eaton. If any of the vendor axles, there would be, (or have been) a tag riveted to the front of the axle beam centered under the truck and viewed from the front. I have never seen a vendored front axle beam under a eastern R model but have on a couple of westerns.

And the analyst:

They can be difficult for someone that only knows what the book states or how to watch for "green lights" nowadays on the alignment rack. For someone that actually understands what the angles and settings do, why they are there, and what to look for when the spec can't be met, it's quite easy. So many cannot, or do not look back to the basics when they have troubles to find a solution.

My 64 B-61S will run 57mph with the pump properly calibrated, 18 speed quad, 10.00-20 rubber and 6.34 rears.

Anybody have one of these for sale? I'm needing a little more road speed than the 4.17 ratio offers and 3.65 is the fastest available in the CRD-93 series. A drilled and studded carrier would be great as the truck is air ride. Thanks, Rob

1975 was the mandate of service, and emergency brake systems meeting FMVSS-121 at the time: https://www.law.cornell.edu/cfr/text/49/393.40 I did think that included the mandate of brakes on the steer axle and have for many years. Glad to discern accuracy. Thanks,

You are correct but it was 7/25/1980 the rule took effect. https://www.law.cornell.edu/cfr/text/49/393.42 I did think it was 1975. I put a lot of front brakes on former tractors converted to dump trucks in those days, but that was because of a fatality accident the owner was responding to.

The 522 is under a B series and too narrow for the R. The stamping is around the right side spring saddle of the axle beam. Look from the front of the truck.

Not much of a difference in the way anything drives with a trailer on but it can be a hairy experience when slick and bobtail. The IH must be a tandem truck as 4 wheel brakes were mandated in those years but not on the steer axle till the 1975 model year for all trucks. 1974 and back front brakes were an option on a tandem chassis. Always liked the center point hubs on a power steering truck as it helped them return to center easily. Particularly if the hydraulic system was "Garrison" as it really didn't have a good RTC unless with center point steering.

Probably an FA-511, or FA-512 which were very common in that series in those years. The hubs make the axle look narrow compared to the later styles.

There is very much possibility the 5831 series had no sub variants so that may be it only. Usually the "A" series were a deep reduction, and the "B" was not so much as example. That was specified by the original purchaser, or whomever ordered the truck. Don't think I've seen an auxiliary trans in a truck with a two speed rear myself.

That is a hard one to find parts for being so small. What variant is it? There could be A-D available, and these determine ratios. Thanks for offering it up before arbitrarily scrapping as someone may make use of it.

Don't think I've ever seen a gray Kysor unit; all were beige I've seen.

I've not found one either and my truck is a 1980. Is yours a Kysor, or Red Dot?

12 speed is a fine transmission and yes it will slide in there. I can't answer if your existing mounts will work as I've never actually done this transition myself. The 12 speed will have five reverse gears and it has a wide variety of pto speeds if operating say a pump. In tailgating, not really a lot of difference from anything else once you find the gear to set road speed as needed.

Wedge brakes work fine if maintained properly. Most aren't, or weren't when they were commonplace.

Cooling system restriction, water pump weak, thermostat not modulating, are all good indications of the symptoms you mention. If you hold a high idle speed and the heater increases it's discharge temperature, there is not enough coolant flowing through the core at low engine speed is the long and short of it which very often is a weak water pump, or restricted cooling system. Same thing with the engine cooling as the coolant is dwelling in the radiator too long removing heat before it's circulated back through the system. On my own trucks I'd drain the cooling system down, remove the thermostats, refill with a mixture of clean water and a commercially available cooling system flush in the correct ratio for the system, and allow it to operate per the instructions. Then flush with clear water, reinstall new thermostat(s), and refill with a 50/50 mix of anti freeze/distilled water combination. Certainly wouldn't be a bad idea to replace the water pump at this time, but most won't if it's not leaking. I've seen several water pump impellers eaten away or noticeably compromised on engines over the years although not leaking so not a bad idea to replace with a high mileage, or aged engine. Just my thoughts.

Personal preference thing but I always liked red frames and running gear under the B series. My 1962 B-673 is/was green with all underpinnings green, but prior to blasting the hubs/drums clean, these appeared to be black originally. Everything will be red with the sheet metal being green with black fenders one of these days.
