wildebill308 Report post Posted November 9, 2020 Ok didn't follow up so didn't see it was that old. I still think a good air tool oil will work just fine. Bill Share this post Link to post Share on other sites

I have a Ram truck and it's shutter is electrically closed only in cold weather. The purpose is to speed up the warming of the transmission then the shutter opens afterwards.

richard5933 Report post Posted November 10, 2020 Got some Marvel Mystery Oil Air Tool Oil today - it's now the top contender. It has a very thin consistency, and there is a faint hint of dry cleaning fluid odor mixed into the oil. I am running a test to see how well it wicks. I've got a spare Kysor airline filter/oiler, so if it looks to wick well I will put some of this oil in there and see how much oil gets picked up by the air as it moves through.

richard5933 Report post Posted November 27, 2020 Brief project update... Found some Shutterstat Fluid - sealed can never used. The oil inside seems to be good and not gummed up. I was expecting an odd smell since it has a solvent content, but didn't expect that smell to be mildly similar to the smell of Windex. The closest thing I've found to it so far was Marvel Mystery Pneumatic Tool Oil. I'll run some side-by-side wicking tests to see how they compare. The airline filter/oiler on my bus has been on there unopened for 46 years. On initial inspection the screws and fittings seem pretty well stuck and not keen to move. So, when I saw the NOS filter/oiler come up on eBay I got it just in case. The air cylinder rebuild kit was ordered through Ross Air Works, and the Shutterstat itself was bought from C&J in Minnesota. I'll probably replace the air lines themselves if there is any sign of dryness or cracking when I get things opened up. The shutters themselves move freely. I've been keeping them lubricated and have moved them manually a few times a year hoping to get them working at some point. Seems like I've got everything in place now to get the shutters working again. Probably won't get to it till I start working on the bus in the early spring, but it's nice to be able to find all the parts and supplies needed. For those curious as to why? Simple, because I can.

jleamont Report post Posted November 27, 2020 Richard, we think alike. Everything on our coach has to work even if I don’t use it. I could see you actually needing it to help maintain even temperatures. Share this post Link to post Share on other sites

I could see you actually needing it to help maintain even temperatures. Actually, in doing some research it seems that the shutters aid in fuel efficiency as well as keeping the engine at the proper temp. The HP needed for the fan to spin with shutters closed is much less than when they're pulling air through, so having them close when cooling is not needed helps in that regard. In spring and fall, it's not uncommon for my engine to operate below 190 degrees for quite a while, even going down the highway. The shutters will help keep the engine as near to peak temp as possible. The shutters and coolant thermostat are designed to operate as a system, and when only half the system is operating there's no way it can be at its best. Besides, I do like having things work the way they're supposed to. I get a thrill out of seeing the old technology still doing its thing. Share this post Link to post Share on other sites

manholt Report post Posted November 28, 2020 Ray, you can't keep up with high tech, it's old before you can buy it. In Richards case, he's trying, and doing a remarkable job, to keep an old Classic coach running according to the original tech and spec's! Not an easy feat in today's world. Richard, you need to convert the old barn to a indoor workshop & bus garage, ASAP....not getting any younger! Joe, Yup, I too hate it when it don't. Share this post Link to post Share on other sites

When people ask where the coach's computer module is, I like to point to the large box on the firewall over the engine where the wiring & controls are. We have about a dozen large relays in there, and they are essentially the only "computer" in the works. Kind of looks like a miniature ENIAC machine, and it performs lots of yes/no functions at start-up to get all the systems up and running. If things go wrong, it also serves to shut things down. Simplicity at its finest. When compared side-by-side with an MCI of the same era, GM definitely took the road less complicated to get to the same place with many of the systems. I like that.

manholt Report post Posted November 28, 2020 Richard, in 1973 to 1978 GMC was building their own motorhome, chassis and suspension system, GM was way ahead of its time!!! There was over 12,900 units built from 22' to 28', engine was a 455 V8 Olds Rocket, coupled to a 3 speed automatic...its estimated that 8,000+ are still running today and of those 7,000 are registered today internationally! So, yeah, you have a good pedigree! If you won the lottery, you would probably have a garage/workshop that would make Joe, green with envy! Share this post Link to post Share on other sites
rossboyer Report post Posted November 28, 2020 Some did had Olds Toronado engines mounted crosswise vs the length. I had a call a few years ago from a member in Lancing, MI that had a new one in a crate to sell. Put him in contact with chapter president of GL GMCers. Bet it didn’t last long.

richard5933 Report post Posted November 28, 2020 The GMC motorhomes used the front-wheel-drive driveline from the Toronado, but I believe in later years they were using the less expensive Chevy engines as well. Not sure which one. Olds used to make their own engines, and they were great engines for sure. Don't think I've ever seen one from the factory with a diesel, so that must be an aftermarket mod. All of them had transverse-mounted engines, which coincidentally my coach has as well. Share this post Link to post Share on other sites

richard5933 Report post Posted March 3, 2021 Quick followup on this project as it finally nears completion. I filled the NOS airline oiler/filter with the Shutterstat fluid today and got it installed, and then was able to confirm that the shutters themselves now open and close smoothly on their own with air. Guess oiling those shutters over the past few years even though I couldn't use them paid off, as they worked great. Only one piece left to test, the Shutterstat itself. I'll need to get the engine to full temp, and then I'll be able to check to make sure that it closes the air supply to the shutters as it should, and I hope to do that this weekend when I get the coach out for its first run for the season.
