Following on from my pump related thread https://www.correctcraftfan.com/forum/forum_posts.asp?TID=49584&PID=593966&title=electric-motors-near-fuel-tank#593966" rel="nofollow - here , when I disassembled one of the pumps for inspection/cleaning/maintenance, one of the bolts broke off in the bearing housing/motor cover plate (not sure what exactly to call it). Now I need to drill that broken piece out. To do that, I'm going to have to pull the housing and bearing off the shaft.  Questions:
Thanks for any help here! ------------- 1982 Ski Nautique PCM351W RR II Velvet Drive 10-17-003 1:1 II PerfectPass Stargazer Do not go gentle into that good night. Rage, rage against the dying of the light. |

On my Sherwood the bearing taps into the housing and then shaft thru bear, reverse process. PBblaster Not sure you would want to try and tap bearing in with windings attached But let’s get a second opinion here |

Pete, in this post from https://www.correctcraftfan.com/forum/forum_posts.asp?TID=39230&KW=3%2D36&PID=509709&title=how-to-clean-engine#509709" rel="nofollow - this thread , you recommended CRC3-36 for rust prevention. Can that also be sprayed onto the components of an electrical motor to prevent rust? Or not a good idea? ------------- 1982 Ski Nautique PCM351W RR II Velvet Drive 10-17-003 1:1 II PerfectPass Stargazer Do not go gentle into that good night.

From the looks of the pump, it looks pretty good inside so I suspect most of the corrosion you are seeing is external. I wouldn't hesitate using the CRC on the pump. The only place I would avoid is the armature commutator. External you may even want to consider LPS #3 if you can get it over there. Getting that broken bolt out could be a problem if you're not careful drilling down the middle. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Dremel makes a micro-diamond bit I used it to start a pilot hole in a broken off ‘easy out’ extractor. Worked good may need 2 Drill and chase threads out Be careful with extractor, they snap and double your problem |

Back to your original question, assuming you don't have a press, if you use a brass hammer and hit the end of the shaft while holding or supporting the end cover either the shaft will come out of the bearing or the shaft and bearing will come out of the housing. A little heat from a heat gun will help if it's being stubborn Don't go "early caveman" beating on it if it doesn't work. Finding somebody with a press would be better and easier than the puller you linked Here's some info from CRC on motor cleaning in the link below http://www.techni-tool.com/ARTICLES/CRC-Water-Damage-Guide" rel="nofollow - link And here's a CRC catalog with the 6 bazillion products they have http://www.crcindustries.com/" rel="nofollow - link

Oops. Guess I should have taken more heed of the 'early caveman' warning. Broke just after I had gotten it moving off the shaft. Well at least now I wont have to struggle with getting it back on again. Thanks for all the tips and advice though, hugely appreciated as always. ------------- 1982 Ski Nautique PCM351W RR II Velvet Drive 10-17-003 1:1 II PerfectPass Stargazer Do not go gentle into that good night.

No, it's a zinc die casting. https://en.wikipedia.org/wiki/Pot_metal" rel="nofollow - Pot metal - Wikipedia

You big brute you  , at least you got a CRC catalog and you probably really have no need to get into the other pumpsIt does look like it moved a little like you said
