Time will tell.... how did you get the seals reinstalled and seated properly?

Re: Water in upper housing?(added photo link)

Looks like the parts are already shipping from ordering yesterday which is nice. If it turns out I need a special tool to seat those properly, what kind of $ am I looking at? I am pretty sure the whole thing will be quite a bit cheaper than bringing it in and having a shop do it for $200/hr labor, but I could be wrong.

I bought a seal installation tool kit from Harbor Freight. Some auto supplies also have them. Buying the kit gives you a broad variety of sizes that woked for resealing all the Intermedite, Upper and Lower gear housings.<br /><br />The $200 an hour could be because they don't really want to work on the OMC IMHO.

Re: Water in upper housing?(added photo link)

I bought the upper seal kit and the water pump kit all for about $100 yesterday and it shipped this morning, so barring any real trouble getting the upperdrive off to work on. I should be good to go.

I lubed them up real nice and drove them in very very very carefully with a big socket. Shadetree, I know, but it worked!

I did my upper and lower OMC dr. and many seal in outboard. by using PVC pipe with diff size and a hydro press to remove and press in all seal much easy. Just make sure you square the seat as it goes in and after you complete all the seals next test you seal job with a vacuum and pressure pump to 10-15lbs and check for any leak in 30 minutes.

Mahoney, make sure the seal is face back to back, one for seal out water the other is for seal the oil, If you not sure what I am talking about look at the repair manual how the lip of the seal suppose face. It is very important how they position 3-4-05

Re: Water in upper housing?(added photo link)

Well I got it apart and the water pump housing was definitely cracked, parts on the way. I still cannot figure out though how water is getting into the gear oil from looking at the disasembled parts. The space in between the top of the impeller housing(opposite the impellor) and the reciever space for the drive shaft is totally dry with no gear oil penetrating from the upper gear assembly past the seals.<br /><br />I also have a upper seal kit on the way, but I am curious to know where the water is getting in from. Any ideas? What pics could I take to help you figure it out?<br /><br />Thanks

Re: Water in upper housing?(added photo link)

Are the seals still seated properly? I found that whatever cracked my pump housing (had to be freezing water) moved my seals ever so slightly. This caused them to leak. Not knowing any better, i just moved the seals back to where they should have been and thought all would be well. It wasn't until then that I started leaking gear lube. Replaced the seals, and all was well again.<br /><br />You'll want to inspect the upper housing, with the gear/water pump housing removed, for cracks. There's a very slim possibility that the housing is cracked. I would think, however, if it were cracked it would lose gear lube very slowly.<br /><br />Still sounds like bad seals to me. Can you post some pics of the WP housing and the seals? I'll try to find my old housing when I get home and post a pic of it... I'm curious to see if mine cracked the same as yours.

Re: Water in upper housing?(added photo link)

#1) Each shaft has 2 seals back to back. One seal to keep oil in and the other to keepwater out.<br /><br />#2) The brass bushing and seals around the steering gear shaft are known to fail and cause intrusion.<br /><br />#3) You have it mostly apart now. Do the complete reseal job.<br /><br />#4) BUY A MANUAL!! before you get into trouble.<br /><br />EDIT Nix #2 on your drive... I just saw your pictures, you do not have tru-course steering.

Re: Water in upper housing?(added photo link)

KaGee: He's got a high-profile stringer, it doesn't have tru-course.<br /><br />But I agree... if it's that far apart (drive's off), might as well put the whole kit in.<br /><br /> EDIT: You edited before I submitted... nice catch!

Re: Water in upper housing?(added photo link)

Thanks guys, Ill take some pics after work. I do have the manual and the whole drive apart, the lower is seperated from the upper and the water pump housing is removed. <br /><br />The part I am stuck with now is the shaft socket that recieves the impellor shaft rod. It is in the WP housing and I am at a loss of how to get it out to replace the seals. These were the seals I was refering to when I said I could not see any gear lub seaping past the seals. <br /><br />Even though I have the Clymers manual for that year of OMC drive, IT IS NOT the same. It gets me far enough to know about what needs to be done, but many of the pictures are off from the drive I have and I end up doing some educated guessing.

Re: Water in upper housing?(added photo link)

Also on the crack thing, when checking the gear lube after running on the trailer for a bit, I did get a distinct vacuum sound when taking off the top gear lube check screw. I would think if there was a crack in the housing that it would pretty well equalize pressure after running and I would not get this vacuum sound.<br /><br />I could be wrong, its all probably a lot of speculating till I can post some good pictures for you to see.

 

[KaGee]

Re: Water in upper housing?(added photo link)

I needed to see both Clymer and Seloc, and even then there were things somewhat "generic". I now have an original OMC shop manual that took me forever culling Ebay for. But my drive is '82/'83ish... won't be able to help much there. My Seloc manual goes back to 64. Might be able to help you there.<br /><br />

Re: Water in upper housing?(added photo link)

That diagram is not totally representative, but pretty damn close. Yes, that is the area of seals I am talking about. There appears to be no oil whatsoever seaping around them into the housing.<br /><br />The really confusing part(and this is the part the diagram and the manual does not show) is there is a nother section of housing around this area so you have to go down about 4 inches or so into this housing to even reach this shaft. Ill post pics this evening.<br /><br />Hey and I appreciate the time it took to mess with that image and post it!

Adding link to pics. The pics are on page 2 of the new upper housing disassembled.<br /><br /> http://client.webshots.com/album/167793117hdsLwA

Re: Water in upper housing?(added photo link)

If I'm not mistaken, and someone please back me up on this, the part you are referring to is seperate from the housing. If you scrape the corrosion out of the inside of the water jackets, do you see a seam? As corroded as that thing is, it ought to be a mother to get out of there. My low-profile drive doesn't have that part... instead the pump housing sits in that part's place (thus, making the drive shorter). My pump housing was corroded in... took lots of soaking and fooling with to get it to come free. Gotta love OMC for this one.<br /><br />Be real careful.. the part I think needs removed is nearly irreplaceable and the housing it is sitting in is big bucks. Imagine 2 styrofoam cups stacked within each other, glued together. Yeah, it's like that.<br /><br />KaGee: Am I correct?

 

[Mahoney]

Re: Water in upper housing?(added photo link)

yup, thats what I thought, there is a seam there.You can barely see it in the last photo there. The metal, although looking very corroded, is suprisingly solid in this area, I will work on soaking it in some wd-40 to get it seperated. Then it will all make sense!<br /><br />Thanks again for all your input. Do you think, even though it didnt look like oil was escaping there, that is my culprit? I am just curious now, as I can't seem to trace the coolant flow channels back anywhere else that would lead to a problem.

 

[keelhauled]

Re: Water in upper housing?(added photo link)

WD40 probably won't get you very far... I tried it and it didn't help. PB Blaster worked a little better.<br /><br />Another recent post had some suggestions for a guy that had a prop corroded on:<br /><br /> http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=24;t=010018#000013 <br /><br />for what it's worth...

Re: Water in upper housing?(added photo link)

This is where the 3rd party manuals totally suck. Especially Seloc. Check out the picture below. It appears that you do not have the assembly apart from the upper housing yet. It's held in place by an O ring and possibly sealer. The bearing housing should look like the picture below. <br /><br />

<br /><br />According to Seloc, you still have to remove the pinion gear, and they say the shaft should be gently pressed out.<br /><br />Sorry this Seloc manual is all over the place, giving instructions for R&R for the high profile and showing pics if the low profile and vise-versa.<br /><br />And to think there are defenders of Seloc!
