water pump o-rings

Postby triketrash » Tue Jan 21, 2014 11:18 pm



Image

if you have a look at this image, you can see what looks like a large o-ring behind the shifter mechanism. I picked away at that sucker for an hour wondering why it wouldn't come out of there. Well, come to find out, it shouldn't. It's some kind of seal that only gets re-done when the case gets split. All I can think to do is run a bead of rtv in there and button it back up. What happens if that thing leaks though. Where is the oil coming from/ going to in that area. Hey if there's a way to screw something up, I'll find it.

I'm going from memory,but I believe that is a bearing cap...It's also sealed quite deep....10mm or so...I think the dimple that runs to the center is a oil path and the cap is used to keep all the oil directed to the large bearing....
If you only picked at the visible exposed sealer and did not move the cap...just leave it be...It should not be a issue.

Never...I do mean NEVER use RTV silicone in a place where it can even possibly get in the oil system.....

My "brother" did this on a valve cover to stop a minor leak....the compressed RTV excess bead came loose inside the engine and migrated into the oil system...it ended up plugging the small oil port on one head and starved it from oil....destroyed that cam in 6 miles.....

Now anybody else can pitch in too....more opinions are needed..

copy that virgilmobile- I guess I'll just button it up and hope for the best... AND try to read the step by step do-it-yourself guides a little more CAREFULLY!

thank you

Ask questions and by all means and get as many opinions as possible....
We'd rather read notes from " triketrash " than read about a "trash(ed) trike"

Definitely Virg- hey if you want to refresh your memory on where that seal it, if you go to the "how to" articles for the GL1100 the photo is on the title page there. It's in the top center of the photo, behind the shifter mechanism.

thanks again

Hey Virg- what about some stuff called "the right stuff" for inside that ring? The guy at the parts store was going on about it. It's a permatex product that comes in an aerosol type application and sets up more like a gasket than the typical silicon type product. I have a hunch you're going to tell me it can let go and plug up just like RTV but I thought I'd ask.

It's not a product I've used before.
I usually stick to what the manufacture used.

I also looked at the picture....in my mind,the black stuff around the cap is not a "O" ring...I think it's the squished out sealer material from assembly.Like Permatex.

I'm not opposed to it as long as it sets up hard ,won't flake off and is impervious to heat and oil.
That's the problem with rtv. It beads up and usually the bead comes off and pieces float around in the oil system
If I were to use any product available,it would be #1Permatex.It sets hard.#2 Permatex sets soft.
I hasten to add that it would be used on the flat assembly contact surface only.The part that gets seated (pinched) in the casing,not as a crack sealer.

Now iffin you hammered a screwdriver between the cap and the aluminum engine casing,pried the cap loose and broke that 10mm thick seal,your only hope is to split the case and replace the cap,seal it back up and reassemble the engine.
Otherwise....move on to more important things,like not damaging the "O"rings on reassembling.
Many will use a dab of grease to hold them in place too.

Just a bit more info...Page 150 in the parts manual shows no seal of any kind.
The cap is a oil passage cap for the transmission shaft.
To my gl1100 reassembling some 3 years ago,I did use a thin coat of #1Permatex on that cap before I bolted he 2 halves together.
Again,If you pried the cap loose,your in deep du du. If you only scraped some of the residue off,no harm,no foul

OK Virg- no I didn't go crazy trying to pry them apart- nothing like that. I just scraped out what I could of what I though was a very entrenched o-ring. The stuff really does have a rubber-like quality like an o-ring and even looks rounded.

And yes- that "right stuff" is exactly as you say- sets up hard, impervious to heat, etc. I'll stare at that groove a little more, read the back of the product again, and make my decision, but from the way you describe the coming together of those pieces, it's the stuff between the parts thats doing the job, not the stuff that squeezed out and that I scraped off. I'll let you know.

Here's a couple of pics of what I'm talking about. I cleaned it up a little after taking these to get those little loose bits out of there but, I think I should be ok without putting any sealer on top of the groove. What do you think?

Looks great.Use a little grease to hold the other o rings in position for assembly.

OK thanks Virg- I guess I'll take that $19 bottle of "the RIght Stuff" back to the store :) The funny thing is, I'm going through all this because I thought it would be a good idea to change the water pump, but it's an upgraded one and looks fine. Oh well, now I know how to do it right for the next time.... if I don't forget.

Forget the answer..????...I can't remember the question..... :lol:

The single most critical point of reinstall a water pump is applying a little grease to the large "O" ring so it is easier to slip into place and doesn't roll out of place.Everything should be snug fitting and never hammered into place.Usually just a good thump seats all the parts.

OK will grease it up nicely- thanks Virg- hopefully I can get this thing buttoned up this weekend and see if it still runs.
