Oil Baths are my favorite as well although running them with turbo chargers makes me a bit nervous. The used engine oil is usually clean enough to be used in oil bath air cleaners so they are pretty much free to operate, lots of people seem to hate them now though

Good grief you're right! I don't know how I didn't notice that before, and I keep forgetting that this isn't the original engine. Granted it's been running with this setup since the 80s or 90s and the engine is still very strong with little blow by but I still will take the tubes off to make sure its not dusting itself out. Maybe I'll use a piece of paper or a smoke test to see if any air is back feeding through the intercooler.

Got in a new temp gauge (175 degree thermostat turns out) and gave the engine a good bath but it's still pretty greasy. Gave the radiator a good clean out too, lots of dust in there. Did Mack use orange/reddish primer or is that the original color of the engine and it got painted grey later? Next two items on the list are valve lash + valve cover gaskets and the doors need attention. Not sure what I'm doing with these doors but looking for threads/advice

The AC panel Is just gone so I guess I'll be on the hunt for one of those. Good sized nest up there too which may be why it started leaking

That's what the PO said it worked really good but too many leaks to keep it running. I just am not sure where the controls would be, there is no "vents" its just an open hole (I'll take a pic if I remember) I think I'm missing some parts from the inside.

After a rain shower I noticed that I had a puddle of water on the floor. Looks like the Kysor AC roof unit will also need some attention. Don't need AC but If I need to seal it back up may as well get it working again. Parts or anything still available for these? I'm not sure what parts are missing from mine or how it was hooked up. The lines are still hooked up but I'm not sure about the electrics since the tag says it 24 volt.

Yes sir you are right it is the capillary type but I've never seen one that looks like that, I'm used to the metal shrouded ones. I swear I had a couple spares laying around but alas I will have to make a trip to the truck parts store.

I will have to take a closer look and see where the turbine vent/check-valve is because I haven't found it. That Farr air cleaner doesn't deaden much of the sound so that also makes it pretty loud. On that note does the tip turbine have an oil line going to it or does it have a sealed bearing for the turbine shaft? Does that bearing ever go bad?

Yep did that and they are moving just fine but it is adjusted so that they are open all the time so there might be something wrong with the shutter unit. It would be nice if the Shutters worked but since it's mostly a summer truck they won't be used most of the time anyway.

Well I found it just where you said it was and it matches the vin number (since it had frame work done I wasn't sure If it would). So it did have the ENDT865 in it originally, how neat! What year was the RS700s introduced and about how many did they make? Another thing I want to tackle on the truck Is setting the valve lash and cleaning/resealing everything. Do I need to remove the tip turbine unit to do this? or just the pipes going to it?

How can I tell if my truck is a Hayward? Did they make RS700s in Hayward?

It has a vin but the door tag is gone. Before the 1980s the Vin system wasn't standardized so there isn't much besides the serial number, and each brand was different. I'll take a look at number on the frame and see if it brings any useful info. Is there a decoder or would I have to send it into the Mack museum?

The door tags are gone or have been painted over. I'm not sure if there is a number on the frame that would tell me or just how I would get that information.

Thank you for all the support and advice! Happy easter as well! Still trying to get a coolant gauge back, so we taped the wire we thought it was to the sensor with no luck. Not sure if that center part comes out without dumping the coolant but hopefully I can wire something back up. How do you test the gauge? Should it move when it's grounded or when the circuit is open?

Thank you for that it looks exactly what I've got. What IH manual did that snippet come out of?
