Shaft binding after pump rebuild, plus tips & lessons

[eastcoastjumper]

I have assembled a dozen solas 144 and 148 pumps and have never used the oem washer behind the prop. I have always used aftermarket washers. The oem washer with the rubber binds and rubs against the seals, or bottoms out like youre experiencing and locks up the pump.

Also with fresh seals the shaft isnt going to spin fast without resistance. What you're feeling is normal.

Get a few different thickness washers from jetmaniac and reinstall your impeller.

Last time I screwed the impeller down, the washer was seated too tight to pry out any other way.

So will excess pressure on the seals from an improperly fitting washer lock up the shaft?

"IF" the spacer washer is hitting the seals, Your seals are not fully seated.....

Good point. They were seated pretty well and looked I be below where the washer could contact them. Further making me believe I just had a thrust washer become an immobilizing washer.

If your seals are not properly seated.

That is what I had said yesterday, guess you missed it...

Yeah, the meaning just didn’t click until now.

So did you end up getting this thing together? What was the issue?

Thanks for all of this! It has been a few years and I forgot how these dang things come apart and go together!
