We'll see, the unit is used on some high class cars so can't be terrible. This rig is only used 2-3 times a year so not a big deal just an interesting project. I found a vendor to make a new hose to replace the feed line to thermos valve that had the weird double check valve in it. Turns out that wa...

Things are coming along nicely-just waiting on o ring package. I've been fretting about what oil to ad so did a lot of surfing. I got the SD7h15 clone and found several charts showing PAG100 for that model. Then I saw a big hint-look on unit's label. Says PAG46. The last place to look! Misplaced wal...

Got the evap. out and stripped. Straightened some fins after removing/vacuuming the petrified thin foam covering-kind of like B&S pre-filter. Ordered TVX and drier on ebay. Had to get it out to fix the broken drains and remove valve to flush. I think condenser is stock compared to online pix. Is...

Yes, BFH & puller set aside. As you can see in the photo my puller didn't do all that damage. I feel relieved in having found out a few answers about this unit. Will try to get unit out of rv for clean & flush. Needs some repair as both drain nipples are broken off. A video showed one fellow...

Ok, tore dash apart turned unit down to see back, peeled tar and there are the connections and valve. I read they can only be tested on running system. So I need to flush. Does the valve need to be removed for that? The big worry is after flush, reassemble and charge the valve doesn't work- Change o...

So I've learned. Just looking for anyone w knowledge of system. If I don't find an orifice that may be the reason it failed. The installer left something out. I'll graft one in if necessary.

The ARA number referred me back here?? My '86 Minnie has a '93 ARA evaporator. The return line is small braided hose coupled to the normal size about a foot from condenser. At that coupling is a spring loaded check valve. I'm not finding an orifice tube anywhere. The connections at evaporator are co...

After pulling radio se ARA tag on coil housing. Where hoes connect are large tar like globs of insulation. No apparent orifice tube. Return line is smaller braided hose with metal coupling mating to larger hose near condenser. That coupling also contains a spring loaded one way valve. My son thinks ...

I'm curious as to the scenario of the destruction. The first thing found was a bunch of magnet wire jammed in clutch grooves. It must have taken a lot of heat to do that to magnet. The 510's demise may have come in seconds or even hours but not instantly. As the new pump is on the way I'd like some ...

Ok, things went fast today-must be the cooler weather. Yanked 510-there was no Freon. First hint was opened oil drain and 1 little bearing needle fell out. Stripped it and the inside looked like a knocked out tank. Ordered the sd7h15. And now must decide about other new bits. Perhaps everything shou...
