MP40 dryside replacement

[mfinn]

I finally had a MP40 dryside go bad. ( actually wife knocked it off the end of the tank and the dryside hit the floor.)
Anyone have a link on the procedure to disconnect and reconnect the cable going from the dryside to the controller?

it's very simple, pull the big knob on the front part of the controller, and there are 3 screws in the back of the controller. Unscrew and remove the covers and there you go.

Thanks. I've never taken one apart and figured that I would ask before doing something that's going to cost me more in the long run.

This video will show you how to go about it

How about any videos on how to take the dryside apart?

I have another dryside that's suppose to be here today, so I felt safe enough to try a little diy. I couldn't find any videos specific to the QD model, so looking at several non qd model videos, I thought what the heck.
So I just stated removing screws, plus the backing sticker and one of the first things I noticed was there seemed to be a rattle inside.
So I got to the point where I removed the magnet/flywheel part and it came out very easy.
I almost didn't need a allen wrench.
I got the assembly out of the casing and there was a third set of screws that were so tight, I couldn't get them broken loose with the cheapo screw driver I have. Thought about running down to lowes and check to see if they had any case hardened #1 screw drivers.
But it this point it hit me there was no rattle coming from the unit.
So I put it back together and using just a screw driver in one end and a allen wrench in the other to tighten the magnet assembly back together.
Put both ends back on and there was nothing rattling around inside anymore. It was solid.
So I plugged it in and,,,,, nothing. Then I held it up to my ear and I could hear a very quiet whirr.
Then the ultimate test, I put the wetside in the tank and attached everything and hit power, and like magic, it was working again!!!!

So after all that, I figure the magnet/fly wheel assembly must have just gotten loose enough to knock everything out of alignment inside to seize it up.

Now I have a extra dryside ( coming today in the mail lol)
