All kidding aside, I read once that hot water does make clearer ice cubes and makes them faster. The hot water is supposed to have fewer trapped gasses in it (just like you said).

You've got one of the best in the business helping you there, 'Mutt!

Yep. One of the biggest challenges when designing a bearing assembly, or any other assembly for that matter, is to calculate what parts will grow in what direction and what that growth will do to the assembly. Lots of factors there. Coefficients of thermal linear expansion of all the different materials. Type of lubrication. Phase of the moon. Neighbor's wife's bra size. You name it. One of the most fun things I have ever done is build precision machine tool spindles. Tolerances in the millionths of an inch. Things where the ambient temperature, and the temperature of your hands, affects the build-up. Those have to be pre-loaded to run accurately, but will instantly burn up if set up too "tight". Really enjoyed those, though. One of those things where the extra time spent getting it "just so" pays off in seriously longer service life. Dang. Getting teary eyed and nostalgic now!😂

Sure! Let's go with that! As good a reason as any!

Thanks, JoJo.

Maybe the upper tray holds more cold air in the bottom tray, making it somewhat different?

Did I miss something here? Was there a deleted post I never saw? LOL!

"If you've held a tailgate party at a funeral..." Speaking of funerals, I just heard that one of my toolmaker mentors passed away a couple of weeks ago. Kenneth Monroe Roper (aka: "Hawkeye") left this world at the not-old-enough age of 75. I learned a lot from that guy, and I will miss him.

"If your coveralls no longer cover all..."

Sounds like you've pretty much got it figured out. We routinely build special tapered roller bearings for certain customers with zero clearance or even with preload. But, these are typically heavy load/low speed applications. The higher speed bearings always have clearance in them. Of course, there are other factors to consider. Depending on the application, the materials used in the assembly, and the way they are mounted, tapered bearings CAN actually loosen up as they heat up. But, with a back-to-back mounting with a steel spacer in-between, they typically get tighter as they heat up. Keep us informed!

I'll try to remember to look that up in my service manual and put whatever information they have about it on here. I think it's just a mention that it exists, though.

I guess he got what he needed??????

Definitely sounds like the bearing spacer could be too thin (making for too little clearance). Tapered roller bearings CAN run at zero clearance, but at reduced speeds. Axial clearance of 0.003-0.007" is more common for higher speed applications. They are pretty forgiving.

There's a picture of that center section in a shop manual I have. They just referred to it as an "auxiliary" gauge panel in there. I'm sure Mack came up with some cute marketing name for it, though.

Drove a Super 10/Top 2 one time. That's been a while. Thoughts and comments on it withheld!

Has the accessory gauge cluster in the middle of the dash. Nice!

Man, those bring back memories...

I think the only way that thing would look better would be if it was sitting in my driveway.

I'll bet you'll be very happy with the results. Keep us posted!

I will try to find some instructions tonight in a couple of different books I have at home. If I can remember to look. I don't think there was any adjustment in the pressure plate. Seems like a cam plate and a threaded rod were the adjustment points. You wouldn't happen to know if this is a single or a double disc, would you? Double disc had shims under the pressure plate that had to be taken out to regain clearance as the plates wore. When a new set were put in, it was important to remember to put the shims back in.

Volt meter on my R600 was grounded through the case (1-wire gauge). So, I had to get a different, 2-wire gauge so I could reverse the polarity at the gauge. It had insulaotr bushings to separate the metal case from the dash. My fuel gauge did not work. But, I don't know if that was related to the system being changed or not. I just checked it with a dipstick! Oil pressure gauge was a manual gauge (copper tube), so that was not an issue. Temp gauge worked, but I can't say what all had been changed there. Did I mention already how happy I am that you are here now?!

Amen, Geoff.

I don't remember the flasher caring about polarity. But, I have been wrong at least twice today already.

Yours too?! Thought it was just the one on Marion! LOL!
