Rebuilding an intermediate housing - help!!

[Frosty]

OK, so my intermediate housing bearing is shot. I ordered up the replacement bearing, oil seals and cerclips. All ready to rebuild. Pulled the rear seal and cerclip and attempted to remove the shaft... yeah, not going anywhere. I know they are pressed in... but I thought I might be able to do it myself. :banghead: :banghead: :banghead: :banghead: Frosty's getting angry...


Anyone ever rebuild one of these? Did you need a press? Anyone got a press and want to rebuild mine? Is Paul's (Magoo's) shop ready for service yet?

you dont actually need a press, Tricky rebuilt mine with a hammer and a steel pipe the same size as the bearings, actually, it was the outer shell from a bearing that he used.

 

[Frosty]

cool... I'll have to give that a try... Thanks Harrison. :biggthumpup:

I am going threw the same thing now. I was able to pound out the shaft with a large ballpeen hammer and a round steel bar on the end of the shaft. All it took was a couple of sharp strikes with the hammer and the shaft fell right out. But i will press it back into the new bearing assembly.

If you can find someone with a large vise that will work if you use it like a screw press...Mine is huge and does work good for that if I need to, sometimes the press is more pain to use!

I was able to get it done last night. Used Harrison's idea and had a pipe with an OD about 1/32" smaller than the ID of the housing itself. So I was able to pound the bearing right out. Installed the new bearing, clips and seals... all set... once I got on a roll I put my entire SN together last night in about 2 hours...

Thanks all for your input... much appreciated!!! :biggthumpup:

how do you know when you need a new bearing?

 

[WaveDemon]

if I were to inspect it would a bad one make noice and have play?

for me... on the 4th of July I hit bottom from a huge nose stab... right after that (once I rebuilt the nose of my ski) I was getting a vibration from the front of the tray area. While doing tail stands you could here it.

I pulled the housing - I could see the front seal was mangled and when you hold the housing in one hand, the coupler in the other, and spin it back and forth, I could both feel and hear the bearing grinding away.

I stole my housing from my SN so I could still ride while I rebuilt this one.

it should be smooth with no noise.

Good point Yamasaki. Just because the seals are ok on the outside, and you cannot see and visible damage, your bearing could still be shot. I had both visable damage as well as internal.

demon, you'll know if your bearing is going.. you can feel it... especially when you are low speed, then get on the throttle hard... that's when I got the most vibration and grinding sounds.

if you access to a press it will make the job a breeze, it took me 2 minutes to press them out and new ones in. the press makes it nice to get them exactly were you want them with out any undo stress on you or the bearings.

if you ever hit bottom, you need to check the lateral alignment of your motor, I hit bottom last year, ended up shreading the shortshaft and driveshaft, motor shifted.

Yet another good point BK.

At first I thought I had an alignment issue after I hit bottom. The kenney keepers worked great to save the motor mounts and all... but the motor was still cocked and out about 2mm from side to side. After I straightened it out I still got the vibration.. which led me to the housing.

Is that bearing greesable and if so, is there a nipple ??
I can't take a look at my ski till the morning and now that I'm reading this thread I'm starting to wonder.
It appears that I have a slight hum right in that area and I think I can feel something in the front part of the tray when I ride.
I haven't had this ski for long so I'm not to familiar with it but I am starting to worry.

The nipple is the infamous dangling nipple on the end of a hose that most of us with aftermarket heads have flopping around the rear of the engine compartment. The hose goes into the housing itself on the starboard side of the ski and the hose is about 15" long. Some or all of it may have been removed on yours.

Great, now all I have to find is the hose.
I know it's not on the head so it must be flopping around in the bilge.

OK, any recommendations on grease ?

if you are running the stock carbs it may still be connected to the intake manifold. From the factory they are mounted on a plate - tray side of the carbs. You can't miss it. If you are running after market carbs/intake mani then yeah it might be a flopper. I have mine zipped tied up toward the electronics.
