That is a hydraulic puller, the bearing is pressed into the brass cast body. To remove it you need to press it in order to not damage the bearing. Taking a press into the field is unrealistic so I have the hydraulic puller and I make that into a mini press.
Thats an interesting video and a good explanation of how a lip seal works. Did you pre lube that lip seal as well or doesn’t it need it? Also on the pre lube is there no advantage to putting some around the inside of the pump housing before fitting the impeller? Does the pre lube help prime the pump as well as initially lubricating it, and if you don’t have the silicone pre lube what else can you use?
If you are still responding, what is the part number for the rebuild kit and also what is the part number for the new shaft? Great video, thank you in advance!
Hi just to clear something up are you saying that the seals should have the grove facing the water and the other side again facing the oil side? so looking from the top of the pump the seals are back to back with the flats of the seal
There are two seals. the lip should face each respected fluid. Lip seals usually have a spring inside to assist the lip, think of this as the side to face the fluid you wish to manage. I hope that makes sense. You end up with each seal facing each other. Just be sure the shaft isn't worn such as a groove has developed as this will reduce the seals efficacy and potentially stop the impeller generating vacuum and hence water flow.
Thank you for taking the TIME to explain the hydrodynamics of the lip seal and how that comes into play with how the lip seal actually seals against water intrusion. You taught me something valuable today that I will not forget. In the process you took me beyond just "remembering" how it went together and trying to put it back in the same way, to a much better place where now I UNDERSTAND how the seal works and it makes PERFECT sense. Such things are obvious to you, but were not to me. Thank you for that valuable piece of education. If I may make a respectful suggestion; please turn down (or eliminate) the music playing in the background of your video. The music gets in the way of hearing your running commentary which is VALUABLE. Honestly, the repetitive and monotonous background music (only my opinion) takes away from the quality of your excellent video. Respectfully
Couldn't agree more with you regarding the music. It was a learning curve I now know to wind back. I try to keep music for anything thats not got anything to he explained in. Really glad you enjoyed this. Thanks for the positive criticism it helps.
@@dhcrouchmarineltd3049 Again THANK YOU VERY MUCH. I enjoy LEARNING and you definitely taught me something valuable about lip seals-great stuff! -Repectfully
I think Parts4engines is where I got the kit. Also it's worth checking Xylem's website as they are the manufacturer of Jabscos pumps. But do bare in mind the work to make a shaft like that. The cost is a reflection of that
i never thought i would learn something from this guy, but i did... thanks mate..
Big thanks, even bigger than big!
Thanks for an informative video. Cheers.
First time I ever used 0.5x speed on some of the playback !!
Lol
The hydraulic strong back pullers I find on the internet don’t seem to have the screw option for applying the force ??
What is your question exactly
Thanks for the video. How did you determine the correct distance to press the parts on the shaft?
The shaft has a ledge that dictates positioning. Once the bearings are against this ledge / shoulder the rest makes sense.
@@dhcrouchmarineltd3049 Oh perfect. Thanks a bunch. Getting ready to do a rebuild on this same pump and this has been helpful.
And now I know ow why a lip seal is a lip seal
Great video 💪🏽
Ha Darren! I could have done with this a few days ago..... Hope you are well fellah.
Hot hot hot, were all good mate. Hope you guys are well too
What do you call that black vertical press thing? Is it required in order to remove and reinstall the shaft?
That is a hydraulic puller, the bearing is pressed into the brass cast body. To remove it you need to press it in order to not damage the bearing.
Taking a press into the field is unrealistic so I have the hydraulic puller and I make that into a mini press.
@@dhcrouchmarineltd3049 Great. Thank you!

Silicone grease is great for pre lubing the impeller and seals in this application.

Which part of the world are you in. Here in the UK that pump is covered by Parts4engines under perkins 4.108.

What type of pump is that exactly?im trying to rebuild one now,I’m in Brisbane Australia ,any help would be appreciated 👍
This pump or a variant of it.

next time your in i will hand over all the jabscos and johnsons iv got most are new il never fit one canal side i doubt again spares / repair mate
I'll make good use of them.
where duo you get your parts from, a shaft from asap is £100
Try parts4engines
I think Parts4engines is where I got the kit.

What’s the spare big O ring for.
Probably a spare.
Leaking pump reason for service?
No but was noted. The engine hadn't had a service at this stage to a known date as no service history was offered.
@@dhcrouchmarineltd3049 I have same pump leaking water out of the drive bearing seal? So thought I would ask. Pump is still functional
Music is too loud
Yes.
Well, it looks like it's time to buy a hydraulic puller!
Very useful indeed.
Jeez, get rid of the repetitive annoying music.
Thanks
Do you realise that at about 9 minutes in, I can't hear a word you're saying for that awful music?
Yup. Thanks.
