Thread OD would never be bigger then nominal size. .002-.005 would be typical clearance on OD on something that size. So, 22.5 mm is .885, so .881 is right on. ISO...... ugh, don't even bring that up around my work. We tried that like 15 yrs ago. What a failure that was. We had two different people/places come in and try to get us certified. Never happen. The owner thought we needed to be since we deal with Automotive stuff. Lucky we are like 3rd tier and not considered to need ISO certification. We wasted A LOT of money both in time and material(mostly paper). Some of it helped with paper trail and forms we still use today. The rest? Fogettabotit.

Nothing worse then being on the motorcycle and getting stuck behind someone smoking one of them turds with their window down. 'Bout turns my stomach. I suppose not all of them smell that bad? I don't care to find out personally. Luckily none of my close acquaintances smoke anything at all.

That firetruck is similar to this one for being short and to the point:

Threw pitch gauges on it this morning. 1.25 mm or 20 TPI. The 20 actually fits better, but at .881 diameter it can't be 7/8"? Has to be 22.5 mm x 1.25 thread(just because). Likely just order the nut from you link Jim. Thanks.

.866 is 22mm so figure 22.5. Was going to take it to work and throw a pitch gage on it. Yes, likely the nut fell out of package somewhere along the way before I got it. Didn't think much about it til I got home and realized it. Then found out it was bigger then Berg thread. Ugh.

Picked up a new Bendix today. Once I got the handle off the shaft I realized it was 5/16". I put it on my mill and lined the hole up and enlarged it to 3/8" and drilled it for larger roll pin. Only problem is the valve didn't come with a nut? Of course it is larger then my old valve. It is bastard size thread OD? .885. not 7/8" so I wonder if bastard metric? Need to figure that out before installation.

Sounds about right? I need to measure it and see. It's crazy how it just snapped in half and fell in my hand when I went to release the brakes.

Thanks guys. I have the technology to make anything fit!!

The center pin broke inside. It's junk.

The pin broke in half as I pulled it. Lucky I was in the driveway after a short test drive to check out my new jakes. Was able to get the truck in the garage before it leaked down. I poked around eBay to see if I could find one to no avail. Guess I need to upgrade but want to use my antique chrome knob. I hope the pin sizes are universal.

Seem to recall some gimmick you plug into your lighter that made race car sounds. Maybe it was just a spoof on YouTube?

Ya, I remember doing the starter on my B. Ugh, to get that thing wrestled up in there and a bolt? WTH? Now I have a nice, light, aluminum air starter! WIN!

That took BALLS!!!!! (the union wannabee)

I can see how/why the inner race "could" turn. You put preload on the bearing with the nut(against the inner race), but the inner race is not really held in place by anything. It surely does not "spin", but could move if the preload was light enough. In all my years of it, I have never seen a spindle with heat damage/scoring from that inner race spinning at high speed. It is always just a nice slip fit. The only time you run into problems is when the bearing fails and purposely spins the inner race and welds itself to the spindle. That is when it gets ugly.

Welcome to the forums. They make Jakes for those old 673T's, so first thing is to see if it has spacers under the valve covers? Switch on the pump arm? If it has them, maybe the dash switch is broke/missing?

Got 5 hole wheels on it still. Ya, looks like it could use some suspension work? Pins missing? Did someone cut and paste that pivot mount in the frame(like really poorly?) Got a face only a mother could love, but kinda cool in a nostalgic way.

Now that's a truck...

Think I saw something the other day about this, maybe on Facebook? Had some fighters sitting on the floor and looking in decent shape(for being underwater for a long time).

I found the muffler on the cab had near as bad drone inside as the rattle from a straight pipe. I ended up putting a Dynomax 4" "racing" muffler(basically a big cherry bomb) under the cab and then a pipe up the side. Clean look and made it bearable noise level inside. You could get a std muffler and have it ceramic coated silver?

I used a stemco 2 pc on my truck a few years ago. All I could get my hands on in a pinch. Still dry, I've heard horror stories about them, but with the little mileage mine gets I hope it lasts my lifetime. I did the bearing like I do my pickup. Crank it tight while spinning, back off, then snug it up til the lock ring finds a hole.

I have that style of vent in my bunk. Works well. Open either way(front or back) and had detent to hold it. You can get chrome versions too. I can get you sizes if interested. My cab has a passenger side vent. It has a rod coming in the cab to operate it, though it is broke off(and I don't use it since I have a/c). It is under the air cleaner(I have the big cleaner, not the winter/dual inlet style). In the picture, to the right of the heater there is a panel. There used to be a knob sticking out the little hole that you pushed to open the vent. The door over the opening would direct the air into the heater or open for fresh air.

Karen doesnt get quite as excited but after 11 years she still travels with me.

Yup, talented lady for sure. Karen jokes about driving my truck, but we would never get there since she won't shift out of first gear.....LOL!!! I tried teaching her to drive stick some years back. My '67 F100 was super easy, power steering, power brakes, smooth/easy clutch. She would stop before getting it into 2nd gear. I told her she had to PUSH on the gas and GO!! Nope, we made a few slow trips around the mall parking lot and that was the end of that class.
