What rubber part is everyone talking about that means the housing is bad??
Is My FX-1 (second pic) housing junk?? It looks sunk in! It still spins smooth and has no play!

There is a rubber carrier ring around the actual bearing carrier. The ring with the holes.

Does the backside of my housing look normal?? When I removed the bolts the whole housing sorta sprung out like there was a spring on the shaft? Normal??

Would it be normal to only have one shim at the bottom bolt of the housing??

When I removed it I found a 1 little metal washer under it! Im not sure if it was used as a shim or had been there for years stuck between the haul and stock bilge pick up??
Does anyone use shims on there midshaft housing?

that is a shim for the midshaft, please put it back in and seal you midshaft to the bulkhead. I use Ultra Blue to seal mine onto the bulk head. this is to help ensure air cannot get sucked into the pump area and do that cavitation thing we were talking about.

Thanks for telling exactly what to eliminate from his possible actions.

Dirkwiggler, just put some gum & Tiger pubes behind that bearing.

D-ROC - how can you tell if it is shimed proper??

Did you read post #26? (I am going out on a limb here and guess "NO")

Further, do you understand the concept and purpose of shimming?

yes I did read but I am trying to figure out who has shimmed just the bottom bolt?? I am not sure if the little washer I found was a shim or just loose in the hull for years(its pretty corroded and rusty)! If most people on here have a shim in just the bottom bolt then I assume I should too.
Why shim the housing if you shim the motor to line up with the drive shaft anyways?

With a shim in place wouldnt the stock seal on the back of housing not create a good seal too the hull?

When I removed mine it did not have any extra sealant product used on the back, Just the stock rubber seal on the midshaft housing was creating the seal!

The factory manual calls for extra sealant. If you didn't have any, it's because some assclown didn't put any in there after removing it.
There are valid reasons to shim the midshaft.
You need to properly line up the motor with the midshaft with the pump.
The midshaft is right in the middle of this driveline tri-fecta. All three driveline components can get shimmed (most commonly just the motor).

What's so hard to understand about shimming just the bottom? :confused:
Presumably, this is done to change the angle of the midshaft driveline. Probably to align it with the pump shaft. (Though I'd rather shim the pump right).

just put the shim back where it can from. if it was aligned before you removed everything then you should be able to re-install everything back together and get it re-aligned...well maybe not you but someone. j/k. give it a try.

The washer/shim I found is super rusty and the inner diameter is much larger than the bolt that may or may not have gone through it. The midshaft housing doenst really have a rust ring or crust indention that the washer would have probably left on it if it was a used as a shim.

Since some sort of sealant was required and mine didnt have any whatsoever I think if there was a shim in there I would have been taking on lots of water! My FX-1 took on no water unless I landed it upside down!

The only way I will know for sure is when I put the motor back in and it either lines up or doesnt!

thanks for the help!

Are you retarded???

I just told you why the thing is shimmed.

Preventing water intrusion was not one of the reasons.

Do you have any clue how to properly align the driveline?

post a pic of the shim. did you not see which of the three bolts the shim came from? mine has one shim, paper thin on one bolt, top left. thats my ski. i would put it back in if i were you. that shim should help align the pump and the midshaft. i use a thin bead of sealant around the rubber gasket to ensure that it seals up and i don't have to remove everything and fix it.

Like I said, Im not sure if it even was used as a shim! It was just by the stock bilge pick up after I took off the midshaft, could be just a washer that was rolling around the hull for years!

If it is a shim it would have had to be the bottom bolt mount because I checked for shims on the top two before I removed, I could not see if the bottom had one!

You guys must have mis-read about the taking on water thing I said.

I said that I dont think it was used as a shim because my jet ski did not take on water and did not have any type of sealant on the back of midshaft housing!
If the shim was used and I didnt have any sealant on the back wouldnt my ski have taken on water because the stock rubber would not have provided a seal. The shim would have prevented the stock seal from sealing all the way around?

I have never aligned a drive train!

that is not a midshaft shim, you should be good to put it back on. if you did have a leak it could bring on water while sitting in the water and it could cause an air leak into the pump intake area and cause cavitiation while riding. both which you say you didn't have. seal it and re-install it. baby steps.

I just picked up some of that blue sealant today so will pull midshaft back off and apply that tomorrow! I used some JSS super grease the first time so I guess additional sealant would be extra protection.

For anyone else removing your Midshaft housing be prepared for a FOUL smell when you pull it off! Maybe its just mine!
