Hey Wizzard, help me out here. I'm going to try to post up a pic of my line that is dripping oil. I think this may be my water pump weep hose?? I haven't had any problems with my quad, but it is leaking oil out this hole. Any suggestions. see attached pics.

BTW, thanks Buster for getting me back going on the site. I don't know what went wrong. Working normal now.

OK, glad you're back on. You must have forgotten your password and me giving you a new one got you in.

I just have no clue what that line is. I would guess a weep hole for the water pump but with oil leaking out, that doesn't sound good to me.

BTW, do you have the Grizzly 700 service manual? If not, I can email you a link to a PDF version I have of it.

OK, by looking at a fiche diagram, that appears definitely to be a waterpump weep hole. So, have you checked your oil to see if you have antifreeze in it or vice versa? I know on a shifter cart I had with a CR-250 dirt bike motor in it, it got to leaking once cuz I flushed it to hard. I blew out a seal and it started weeping anti-freeze. The fact that it is leaking oil is a big concern to me. Did it start doing this after some major hard run or after normal riding conditions?

If you go here, you can see the hose in that diagram.

I know you slam the power to that thing in the mud so that is why I am asking?

Yes I have it, but I can't find that hose to save my life on the diagram. I don't think anything is hurt, it's running great, just dripping oil. There's no water in the oil, or oil in the water. I think I must need to replace the water pump??? I guess there's a seal in there, I had one guy tell me it can leak water if it goes out on the water side and oil if it goes out on the engine side???? I don't know about that. That's the only explanation that has made any sense to me so far. Unless my crank case vent is plugged and making it blow out down there. But I thought that would cause it to leak into the intake???? not out the bottom. One thing for sure. I need to know the purpose of that hose so I can determine if I need to run it up with the rest of my snorkled lines. I surely don't want a stupid mistake to cost me a rebuild, well, you know what I mean, I'm sure I'll do something stupid one day and have to rebuild any way, but thats when I will go crazy with it. BBK and the works. until then, I want to keep it hummin.

That is the weep hole for the water pump. Are you seeing any water mixed with your crankcase oil? is it milky? Pull that line off and ensure that it isn't plugged off. Your problem sounds like it plugged off, built pressure and ruptured the gasket between the crankcase and the water pump.

All and also check and see if you have any oil in your antifreeze.

Bottom line, I would not drive it or run it until you figure it out! Oil in the coolant or coolant in the oil is never good. Unless you are ready to do a major overhaul.

 

[1Bad1000Xxc]

AHA, and now that I look deeper into the fiche, I see part #14, "Oil Seal". I betcha that needs replacing. It would be a pretty easy and quick job though I think.

If you are good, you MAY be able to do it without pulling the side cover off and just going in through the water pump hole. Small tools need I would guess.

Worst case, drain the oil, pull the side cover, push the seal out from the back and reinstall everything.

Now I ain't a rocket scientist by any means, but if the hose was plugged off, how the hell would any fluid drip out of it GW? ;;s;;

BTW, I beat ya too the punch on your post? :rotfl:

I also feel 100% confident the oil seal I noted from the fiche I linked in my post just before yours is the culpritt.

That being said, I would not be riding until that got replaced to confirm it fixes the problem.

Buster

Your problem sounds like it plugged off, built pressure and ruptured the gasket between the crankcase and the water pump.

oil leaking

I knew I could count on you guys. I had to ride it from the trail to the truck, about a mile, but I stopped several times to make sure the oil looked ok and I haven't seen anything in the coolant. So I think everything is gooood. I will be ordering the seal on Monday. Do you think I need to run that hose up to the handle bar like my other vent lines? It seems like a good idea to me. Tell me where you found the seal in the ser man so I can look at it B-Dub. or send me a pic of it. Again as allways, thanks for the speedy info. Makes a brotha fell a lil better. :bowdown:

 

[1Bad1000Xxc]

No problem dude, it was a mission for me to find it. I didn't find it in the service manaul yet. But that oil seal is in there on page 269. It does look like the side cover has to come off to get to it though because it is behind the water pump seal. If you look on the fiche diagram I linked to, you can see the hose and it is just called HOSE.

I would not run the weep hose up because then you won't know you have a problem until it fills that hose, which COULD be too late if it has to fill 3 feet or so of hose before it starts to come out the top.

The crankcase cover is gonna have a seal on it too which on cheapcyleparts is only 7.85. I would guess that to be an o-ring but for 7.85, it might not hurt to order one just in case it isn't or you damage it somehow in the disassembly process.

Let us know how it goes.

AHA again, found the hose in the service manual, pages 268 and 269, item #5, water pump breather hose. It is defined on page 268 but pictured on both pages.

Buster

 

[1Bad1000Xxc]

BTW, in the service manual the oil seal is item #11. But, on the fiche it is item #14.

It's a good thing I have a service manual for a Grizz, oh wait, that was my quad, no wonder. That being said, the engine was kept cleaner when I had it? ;;s;;

oil

Sweet. I just saw the link you inserted, it didn't show up until I closed the browser and reopened it. That is it for sure. Nail on the Head! I was on it prety hard today, but I was wondering if all the sub freezing weather might have got to it? I don't know. I will get it all fixed up now that I know what it is. I know what you mean about running that line up to the rest, but I worry it might get dirt in it? I don't know, more thought on that I guess. I have a buddy whow rebuilds hondas all day long, he will help me with this so I don't have any issues. He's a good mechanic. I'm a good parts changer! lol. Thanks agan B.

Engine

By the way, I didn't clean it yet, I was more worried about the oil issue, but I assure you, it still cleans up real nice and when clean , she still turns heads. I'll send you a pic of a clean machine after I clean it up. I don't want you to think I let her go to crap. I'm just not afraid of getting down and dirty! lol. straight off the trail to the pic.

 

[1Bad1000Xxc]

Aww, it won't be bad at all. Looks like 9 bolts (10mm if I were a lucky guesser), maybe 8, maybe 10, hard to tell from the angle of the pics.

Nonetheless, once you drain the oil and get the side cover off, it will be a breeze, pull out the oil seal, push in the new one, slap 'er back together. I'm guessing 30 minutes not counting the oil change since you have plastic to remove too.

Let us know how it goes.

Water Pump seals

Well, job is done, with the exception of putting all my stuff back on the quad. Not a very tough job, just have to remove allot of stuff since I got snoks and all. But all in all, fairly easy. I did have to run to a bike shop and borrow a seal removol tool though. The old screw driver trick didn't work here. But got it done and all is well. Thanks for the help and support. As usual, you guys have never let me down.
