Broken shaft on an MP10..fix it for pennies

[Roush2000]

So I bought an MP10 last week off the forum. When i got it in I went to clean the wetside more and dropped it :mad::mad:.
It cracked the ceramic shaft in half. So the ceramic only went halfway up the shaft. The pump still worked but couldnt go past around 40% or it would make a little bit of rattle.
I was really ticked at myself. I see ecotech doesnt offer a replacement of a 10cent part but why would they when they can force you to buy a $65 replacement wetside.
So I found a video a guy used heat shrink
tube

I went right downstairs and pulled the pump and did it myself. PERFECT fix. I used my kit I already had
Shrink Tube

one red then the yellow ontop. The impeller fits perfectly and spins like new without any major resistance and no wobble. I put it back in the tank and cranked to 100% and its dead silent.
Gave it a lube up of the molykote
Lube
So if anyone breaks the ceramic shaft this is a cheap easy fix

How exactly does the replacement work is there something under the ceramic shaft the heat shrink goes over??? And what about the tip at the end that goes into the guard

It's a stainless steel shaft under the ceramic. I just cut the shrink tube off flush with the shaft and it went in fine from what I remember. It'd been a year since I have had the pump though.

This process works great, I have several mp10’s that have been repaired with this method and been running for many months, probably years.

I have a couple MP10s with broken ceramic.
I wanted to find a permanent fix.
I found some Teflon tube that fit perfectly.

I broke the ceramic shaft this weekend while cleaning my MP10 and was cursing having to buy ANOTHER wet side assembly. I found this thread and for less than $10 on Amazon, my MP10 is back up and running! THANK YOU!

Whoa, lets hear more about this teflon tube solution. How long have you used it and what is the performance so far?

Also, what about going for the real think and just buying a big tube of it? Assuming David's measurements are correct you can just buy ceramic pipe with the same measurements

I know this is old but if I Venmo you $3 will you send me a few pieces of the shrink tube? It’s unavailable and I really don’t need that much lol
