Wisconsin AENLD from Refer unit
- Thread starter cjet69
- Start date
Pulled the engine off of the refer unit and hauled it down by the shop to do some tear down. Used a little heat on the 2 head bolts on either side of the exhaust port. No broken bolts so far which is nice. Found a stuck exhaust valve and what looks like a mud dauber nest on top of the piston which kept it from turning over until I removed the head Sprayed everything down with ATF/ Acetone mix and let it sit while I took a coffee break.

Just a little light rust that will clean off easily.
After letting the ATF/Acetone soak for several hours I tapped on the exhaust valve, and it started moving. Kept spraying it down and working it and it's getting to where it will close on its own. Cleaned up the piston and bore some. It looks better now. Time to pull valves and get the seats and faces cleaned up. Removed the carb and started work at freeing the choke and throttle shafts up.

I hope so. I'm surprised how good it looks inside after sitting out for around 40 yrs.
I see the retainer clips for a cap on the distributor so it must have had one at some point. I still need to remove the coil from the refer unit frame and see if it is any good. I need to look on my old computer to see if I have a PDF manual for these engines. Not sure how you set the timing with this distributor setup. I want to remove it and clean it up in the bead blast cabinet and get some new points in it. I don't see a condenser in there so are they mounted externally somewhere?
I found it on the side of the distributor. It was right in front of me but had good camo with the rust and green slime.

If I had to guess, it was hooked up to a thermostat and when the temp rose to above the setting it pulled the governor open and then the unit would start cooling down the box. Look and see if there is some kind of clutch on the compressor or output of the engine. I'm thinking it would have been on the engine and probably a centrifugal clutch.
It does have a centifugal cluth on the engine.
Boy that is hidden good
Disclaimer: I know nothing about these setups, but could that be something that triggers the starter to fire the engine thermostatically? It's mounted on the starter so just a wild a$$ guess. That way no one has to be responsible to start and stop the engine and it wouldn't have to run constantly?
I'm ready to take all the fun you want to make of that thought---LOL!

The reason I I suggested throttle is because if the engine runs continuously the controls for maintaining the temperature would be much simpler. I spent many years working with industrial refrigeration systems but like Doug I never had my hands on one of these. We used to load refrigerated box cars and I remember they had to be started before they brought them out to the plant. Can’t remember if they stayed running while they were loaded.
I’d have to see the controls or a schematic to know for sure.

I'm sure you are correct on it running continuously but coming down to idle once the temp was down. Just like our gas-powered miller arc welder that idles until you strike an arc.
