Pump Inspection

[CDENsomnia]

Hey All,

I know there has been multiple threads on pulling the pumps and inspecting the rear pump bearing. I wanted to get thoughts on my first. It was surprisingly easy to pull the pump. 4 bolts and the steering and gate cables disconnected and she pulled right now.

From what I have seen from others pictures i think mine are good but wanted to check with the brain trust before I start reassembling. I know some have gone with a slurry but I think I am just going to go with Yamalube marine grease. Anyone see any issue with that? Again, just being ultra conservative this first time pulling the pumps.

One other question, I thought I saw where someone documented which loctite to use for the cone screws but now can't locate it. Anyone happen to know?

Disregard the loctite question finally found it...loctite 567!

Looks great! Yama grease will do IMO.
I found the actual OEM pump grease, I can find it for you. But it would take few days to have it shipped.

Thanks @swatski. I got the yamalube for some other stuff as well so I will just go with that for this year unless someone tells me "Heck no!!!". I plan on checking these yearly now that I know its fairly easy to pull the pumps. I was a little intimidated before as some of my old jetski forums you use to hear scary stories about pulling the pumps and impellers. This was almost too easy.

Yours look fine. You do not need to add any grease.

Loctite 567 is a high temp thread sealant. Most auto stores will carry some brand of high temp thread sealant. I am not convinced that simple pipe dope from a plumbing supply would not do just as well at keeping water out of the threads.

I've yet to inspect my bearings. I'm going to put it on my list before the season kicks off soon. But question ) @Bruce or any others) do you have to pull the pump to inspect? Or can you inspect by removing the cone with the pump still in? Just curious, as I've never pulled my pumps.

Regular loctite 242 (blue) does an excellent job of sealing the threads against water ingress. 567 is a PFTE sealant for metal pipe threads. Todd unless you have the worlds smallest hands you can't get at the cones without removing the pumps. Cam.

I didn't want to take the pump out either, during the season I always look and visually inspect the cone. This year I wanted to actually take the cone off...no tool I had would reach in and take the screws out. I had an SX230 that the cone cracked on which caused me to lose the bearing among other things. Honestly, with a simple socket set, 4 bolts out and take the linkages off, its very easy.

The first time I decided to look under the cones I thought I would just remove the bolts and pull the nozzle. When I tried to pull the nozzle I learned how easy it is to pull the entire pump. Just put some moly grease on the splined end of the shaft before reassembly and it will all be ok.

 

[ToddW850]

Gotcha. Thanks for the advice on that. Sounds easy enough I reckon.

Lot of grease in the cone and not much on the bearing. The pic of your cone sitting there and the grease staying in the cone and not flowing all over the carpet ( ...and not flowing to your bearing ) is TYPICAL of the OEM Yamaha grease.
A picture is worth 1000 words:
PS: Regular marine grease is 100% the opposite of what you want to do!!!

The @ISLANDRACING mix is premium stuff, lots of hard running jet skis using it.

This is a bit confusing, but the actual OEM pump grease is indeed semi-liquid for high "low temp pump-ability". Lithium based, nothing special but kind of hard to find in retail (not a 50gal drum).
If you must stay with the OEM grease, this is pretty much the only US vendor I could find:

The US equivalent, "Mobilux™ EP 0"
