Just wondering if there's anything salvageable on the top, besides the controls and bellows (I think my bellows might've been bad, but I did salvage the control).
I've tried powering it on twice. It sounds like it's definitely seized. I'm just wondering if there's anything salvageable, or if anyone could use any parts in the top. I hate to be a dick, but I'd like this top (and probably another one that comes with a porcelain cabinet I won on ebay last week) to go somewhere where it's more useful, though I'm not wild about recycling it.
On another note, I should probably do my research on recovery of the methyl formate, if these machines have any left.

Hey Paul; have you tried any of the un-seizing techniques such as capacitors or use of higher voltages?
If you're not interested in those tests, I might be interested in the top assembly.

I don't have experience with CAs, but do remember this thread of a member cutting open a siezed CA: monitortop.freeforums.net/thread/824/observations-opening-ca-compressor-stuck?page=1Our DRB3 came with a stuck compressor. Starting it backwards did the trick for it, but it is a different beast. Based on past threads, 240v is fairly effective. Higher capacitance can work if you're lucky. Running it backwards (or back in forth) is somewhere in between. |

Another thing I’ve heard to try with a CA is to very carefully crack the screw while it is off since you can’t start it and see if you get positive or negative pressure. If you get negative pressure, air sucking in, you know that NCGs aren’t the cause of the stall. If you get gas hissing out you have a LOT of NCGs in the system and that would cause it to stall. When I first ran my CA it must have been very close to stalling because it did have a ton of NCGs in it and it sounded like a broken Russian tractor.

I definitely don't have the equivalent of an Annie (though I have an ex-girlfriend named Annie, and she could probably get the damn thing unseized with her personality). |

I already took the control off Ray (though I could just short out the two connectors). I'll try what you suggested on this next top I'm fixing to get on Monday (glad I didn't yesterday, with the crazy rain we got).

Be wary of assuming it really is seized. There isn't much of a reserve of motor starting power with the CA, and excess NCG or the heater not working will easily prevent it starting.

I have a plan for an experiment to give one of these a torque boost it will not soon forget. More on that once I get a hold of a seized one!

The relay and control, cord connectors, flammable solvent and enough steel to make 2 Hyundai's.

LMAO about the Hyundais. I wouldn't doubt it, though. I have 3 CA tops in outdoor storage (40 foot container, but the doors are open). A recently acquired one isn't seized, but I have yet to put a Supco relay to it and see if I get any activity on the evap.

Just a follow-up for future readers of this thread. The two CA units were checked out in this thread. We were working on 4 different MT tops, so you need to read carefully to pick out when we're talking about the CA's. monitortop.freeforums.net/thread/1592 |
