Great tutorial, it appears feasible accomplish with the proper tools. I would need a press to get this done, unfortunately I don't have that. Thank you and God Bless!
Thank you! And you could do this using a "low cost" arbor press. These parts don't require much force to remove or install. I just so happen to have traded my way into a 20 ton press shown, which is overkill on jobs like this.
Question: (During reassembly of the shaft into the bearings, you press on the race of the top bearing as the shaft comes through) Doesn’t the race from the bottom bearing have too much pressure on it from the shaft pushing through? Because nothing is supporting the race on that inside bottom bearing… Just curious because I’m about to put mine back together 👍🏼 Would you have done anything differently?
The spacer supports the second bearing outer raceway.. off of the first bearing to install. That first bearing has its outer race supported by the step in the housing. @markgattinger3958 I agree that one of the bearing inner races is not supported. Don't see this as an issue though, no other way around it that I can tell anyway, pretty light interference fit and easy to press. You could freeze the shaft ahead of time, and or also could heat the ID of the bearing, both options would reduce or eliminate stress at assembly if you are quick. I pretty sure I would do this the same way next time though, however I respect your question. I built both pf these and now they are at around 20 hours run time and smooth.
so in the video you use the epnoc grease for everything but the manual calls for epnoc on the spacer and in the cone but calls for Yamaha Grease A (Yamaha Marine Grease) is it ok does the epnoc have the same capability?
I did use epnoc grease for the entire jet pump assembly which is made for jet pump bearing lubrication. I read this about the cone, which is the reserve. The Yamaha marine grease is more tacky, the epnoc is thinner, for my application I didn't see a need to differentiate and simply used the epnoc. ( I also pull these cones annually to refresh things and replace grease in the cone) But by all means, utilize the information in the manual to do this as you see fit, my use case with regard to PM's is what I thought to be practical.

I'm also curious. I wonder whether the spacer can support it in place...

When you are doing the final shaft press at 12:15, is there a positive stop there? Or do you leave a specific clearance?
Thanks for watching and for the comment. That's a positive stop. I pressed until it began to feel firm. No clearance or positioning with that.
@@BondsGarage cool thanks for the response!
