Pump baring Carnage

[orangefinger]

Solas MAG 12 Vein Stator.....baring took a dump

Was it the crack in the pump housing, faulty baring install or just a defective baring...who know's

The hooker also got shaved and needs to be sent in for repair thus the gap is way to big between pump housing and impeller

Outer baring race was stuck in Mag pump section ( got that out in the meantime, dont ask me how ) and inner baring race stuck ( melted ) on driveshaft >> Junk now

Is that a OEM shaft or one of the many cheap AM drive shafts?

that sucks braap.....

 

[orangefinger]

was aftermarket shaft , dont think the shaft was the problem

Wow that's crazy almost like it got real hot. But how with the grease. I'd say bad bearing

 

[orangefinger]

Conclusion as follows ....

2 shredded threads in rear of pump gave pump play >> vibration forced driveshaft to put pressure on barings and rub impeller on wear ring/pump housing >> pump housing crakced which furthermored dislocated wear ring >> ultimately baring gave out >>

I think i have it solved but who knows might have been a bad baring to start with

Ic I have a question. Can u put to much grease in pump

 

[bigo]

so which threads gave way? ones that hold the pump together or the ones the hold the pump to the hull?

 

[orangefinger]

pump to the hull....rear ones, I think they where already shot when i mounted the pump

mine just did the same thing. I believe its because when the shaft is pressed in the inner race takes all the pressure and puts stress on it. First time i assembled my pump the shaft spun snug lasted 30 min and locked up. this time it still spun snug and we will see how long it lasts with the old oem bearing. Its a stupid design. it takes so much force to press the bearings in. Maybe next time I will.

Put bearings on the shaft pressing them on by inner race.

then start a fire and put the stator on top of the stove for 30 min. or in the oven.... if the grease is cleaned out.

Then the shaft might slide in without stressing the bearing.

I am quite sure it was a combination of the rear of pump loose and cracked ( Eggi ) wear ring....i have a press and made sure to press the baring in with pressure to outside and inner ring......done a ton of these and never had the issue before , the heat trick seems to be a good idea

 

[d_moss]

did you press the shaft in after you pressed the bearings in? thats what i did and holy crap it was hard. i need to find a better way

 

[orangefinger]

thats how it supposed to go
