Mp40 wetside ... should I replace it or get the $20 kit?

miserkris · 01/02/2015, 08:57 PM

Hi.

I've been using mp40 for two years. Suddenly wetside stopped and didn't work after vinegar dip. Dry side works.

I tried opening wet side see pic no 1 pls.
I think I broke the center screw. ...

Also to push remaining screw thru magnet disc. .I had to tap it out. Now the disc slightly bulges around the hole. Pic 2.

Am I better off buying the wet side kit or get a new wet side?

Pls advice

thanks.

I had the same thing happen to me a couple months ago. The maintenance kit worked fine to get it running again and it a whole lot cheaper than a new wetside. You might want to consider getting the wetside ceramic bearing as well.

Is ceramic bearing the white washer like thing in my pic? Thx man!

Looks like it yes. You may not need it but for $15 it's worth having on hand (in my opinion). I was fine not replacing but would have preferred to while installing the kit.

Looks like I have all the parts correct for the wet side in the pic right? I kinda feel I'm missing a washer. ... not sure

Looks like there is a semi-transparent white washer missing.

Looks like this

Your washer is there, it's on the propeller side of the magnet. I see it in your picture.

Yes, you did break the screw.

I find it much better to soak the wetside overnight in vinegar solution to loosen it up.

I bought an extra wetside to swap out while I clean one, get it all clean then swap out the other one for cleaning.

Keep track of that little washer. They will run away at a moments notice!
