I could be wrong, but I believe that is the type of shutter that is fully mechanical. It uses a "wax pill" to operate the shutter. No air involved at all.

 The temp setting should be the same as the thermostat, as the sensing unit is in the bottom tank.

Somewhere I have the info on them, as I have that type on one of my Fleetstars.

One of the things I remember it saying is "DO NOT FORCE" the shutter or you can damage the "pill".

On  mine, all I had to do to get it working is to take apart the linkage and paint with graphite paint.

This seems more likely as I haven't seen any air lines go down there. I probably can't change the "pill" thing out without draining the coolant right? I will at least remove the pin and see if the shutters are moving or need lube 

[Geoff Weeks]

Yeah, I don't know if parts are even available anymore for them. I would disconnect the linkage and see that everything moves freely. Other then that, the only real test would be to remove the engine fan and let the radiator heat up, until engine temp is close to 200 and see if they move.

You'll not likely see them move much when running the truck, as they close when the temp in the bottom tank is below (engine) thermostat setting.

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

[Geoff Weeks]

CTS 2301 It covers the Fleetstar line. Volume 2 covers cooling systems.

Here's a so so picture of the interior. Really good shape! Doors needs some attention but everything's there 

Wow! Steel dash! Looks cool, and the steering wheel seems seamless.

Wonder could you find any traces of presence of the V8 in the past? 

[BOBWhite]

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?

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.

Just a question you sure may not answering. If no VIN how can you register the rig?

[Vladislav]

The frame rail is expected to have VIN stamped into RH side near the steer tyre area. But there could be an exception.

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? 

[Vladislav]

This truck was up for sale about a decade ago. Zoom in the pic and you can see where to look at for the VIN. That's RS600 not RS700 but also Hayward production.

And Happy Easter to you!

This year this is the same date for both Catholic and Orthodox celebration.

You would have to contact the museum. There's on-line decoder but it gives general info only. Something like the production year and possibly an engine option, such as Mack, Cummins, Detroit...

I was looking for actual info on my 1988 R688 such as the original engine number etc. Asked a few dealerships in the US (personally) and ended up getting essential info from the Museum guys.

What you may find on the frame is the VIN stamping only. Or the chassis number (which I belive before 1980 and also after 1980 was VIN). BTW door tags also didn't contein engine info.

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

Yes. They made RS/RL700 in Hayward only. Too probably they were Hayward design too. Hayward discontinued them in 1978 (1979?) when RWS/RWL Superliner came to the scene. Production of RS600 continued and after closing Hayward (in 1980-82 time frame, don't remember) was removed to Macungie. So RS600 could be both produced at West and East coasts but 700's were Hayward built trucks only.
