Appreciate the video, just helped my coworker and I not only remove the brass sleeve, but stopped us from blowing the second of two seal kits we had when our dumb selves had the sleeve going the wrong way and didn’t realize until after seeing this. We wondered why the hell that seal was fighting us so bad 😂😂
Amazing explanation. Thank you. Question. What's gonna happen after it cools off? Is it gonna get tight to the shaft and spin with it? I ask because I have one that is really loose when it's in the shaft. I wonder that if I heat it up like you did it once it cools off It'll get tight. Thanks
if its loose it will not tighten up .. heating it expands it so it will fit over the shaft and then get tight when it cools you may not have the right sleeve .
So I have 3 X-Yanmar L70s that we’re on pump duty, & trying to get the old sleeve off to instal a shaft adapter for a keyway. The sleeve is metal & i’m not sure if it’s rusted on of sweated, it’s not an o-ring it has a washer tho behind it tho.
'it' being the sleeve? there are several different types of sleeves .. some use locktite some use silicon some use an o-ring some are sweated on .. it really depends on what type you have.. this is for Armstrong close coupled and they have changed to locktite since this was done
yes is have that is why I have done video's on seal change for this pump as well ..search: ' pump seal change repair rebuild" they should show up .. I made these to specific topics to keep them from being toooooo loooooong...thanks
nope .. a sweated on sleeve will not come off with a puller a lot of companies have gone with gaskets/0rings or lock tight but this is an old school sweat on sleeve .. boom
@thebrainard ...I suppose the surface area being much greater than a bearing makes sense in that case. I usually use a cone heater to drop bearings on, but a puller to get them off. For sleeves, I also normally use a torch, because all ours use loctite.
Shouldnt need to heat these sleeves at all, they should slide on and teflon tape should go against back shoulder. Once the sleeve is installed and the bolt is tightened, it cant go anywhere.

The first time heating anything has helped me. Thank you for the video.
Glad it helped
Great i need the training for this pump Seal replacement

not familiar with those .. sorry
That is really annoyingly simple lol. Really valuable information on how to remove the sleeve, thank you.
I always put mine on dry. Do i need to put a silcon or anything underneath it before installing the impeller setup?

Interference fit. Machined to tolerance so that you have to heat the sleeve enough to expand the I'd of it enough to fit on we the shaft
yep .. you pass the exam .. some companies have gone to a looser fit and use some form locktite
Beautiful
have you ever thought if we are changing shaft sleeves at the point of application of pump, then how do we put the seal!!???
Great! Thank you
You are welcome!
Cool video
Good day sir...how to measure annular clearance?
clearance what to what?
Very helpful + thanks alot sir
anyone knows why there is this.sleeve ???
renewability .. and a throwback to days of packing ... but its there my dear
wow ok .. can pump operate normally without this sleeve.. I'm replacing a new mechanical seal and this sleeve is damaged
you probably know by now .. but no the sleeve is part of the sealing package
changing impeller wear rings?
I don't have a vid on that ... maybe put that on the to do list
Thank you so much!!!
yes is have that is why I have done video's on seal change for this pump as well ..search: ' pump seal change repair rebuild" they should show up .. I made these to specific topics to keep them from being toooooo loooooong...thanks
So good
Got it!! thanks!!
Cool.
If you have access to a shoulder puller, I find that preferable to trying to use a chisel to tap it off.
nope .. a sweated on sleeve will not come off with a puller
a lot of companies have gone with gaskets/0rings or lock tight but this is an old school sweat on sleeve .. boom

they are sweat sleeves .. old school ( vid is how old?) they won't slide on without heating d.a.
Hammerash. Plenty of dints on that shaft from the chisel.
actually not .. the dints are on the sleeve which is not a reusable item
