Default transmission and clutch oil seals - HELP Please

Hi troopers,

After a trip I started noticing that the bike was loosing power. When I arrived home I noticed some oil stains near the swing arm and around the transmision. I went with a mechanic friend and his dad and they told me that must probably it was the oil seal from the sprocket. They also recommended me to change the oil seal that goes with the screw assy clutch.

The thing is that the first one is not in stock here in Mxico and Ill need to wait 4 to 5 weeks to arrive . Is there any "generic" oil seal I can use here?, I noticed it has some measures, so I guess it must exist some generic one.

My V-strom is the 650cc year 2007. I got the parts numbers from a K4 model, dont know if they are the same for K7.

Please advice!...

Thank you.

Some pics of what I saw in the parts manual.

part 36 - oil seal 36X50X


part 23 - 6X34X5

Make sure it isn't just chain lube. A leaky seal will have no effect on power. The leak doesn't sound so bad you couldn't wait for proper parts.

I also own a 2007 DL-650.

You may be able to find a generic seal for the countersprocket. You won't for the clutch push rod seal. If one is leaking, the most likely culprit is the clutch push rod seal. If it is the countersprocket seal, you also want to replace the o-ring -#51- that sits inside a groove on the countershaft, sprocket spacer -#48-.


If it is the clutch push rod seal, a temporary fix is as follows:
1- Remove the front sprocket cover: three 8mm screws.

2- Remove the clutch release mechanism; two 10mm screws.

3- Remove the clutch push rod.

4- Squirt a little grease into the clutch push rod opening.

5- Reassemble.

NOTES:

a- Don't start the bike when the clutch push rod is removed. Oil will pee all over your boots.

b- Before doing this, let the bike cool down.


I have just finished replacing my clutch release mechanism, clutch release push rod, clutch push rod seal, countersprocket seal and sprocket spacer o-ring. I have taken photographs of the whole procedure. I am planning on writing up a tutorial on how to do this. I am just not ready to invest the time yet. However, if you need some assistance and you feel some photographs other then what you find in the service manual will be helpful, I got a boatload of them.

One caution, if you take a look at the online parts fiche, (all of this is under the heading "transmission"), you will notice a metal "seal retainer" that is applied over the clutch push rod seal and the countersprocket seal. There are three 10mm bolts that hold that in place. The aft two are easy to get at. The forward one is a royal pain in the ass. There is no tool that I own that could get in there to remove or reinstall it. I made my own.

I purchased a cheap 10mm socket and cut it in half height-wise. I then made a handle out of some scrap angle iron steel I had and welded the "short" socket to that.


The handle let me fish the socket in to place and loosen the bolt.




The metal plate I am talking about is part #40 in the below diagram. (The red arrows were for identifying the C.S. seal and s.spacer o-ring for when I ordered them.)


To install that difficult bolt, I finally ground a slot in the bolt head so that I could insert a flat screwdriver blade so as to tighten the bolt enough to get my special wrench on it to finish the job. There was no way that I could get any other wrench or my fingers in there to deal with this bolt.

EDIT:

This is what the metal seal retainer looks like.


The difficult bolt I am referring to is the one over the clutch push rod seal. You can also see some grease around the push rod seal. Mine was leaking too and I used the temporary fix that I mentioned above.


Let me know if I can be of more help.

Barry

Thanks Dave.

I do plan to do a better write up on this in a week or so. But, I was concerned about the above fellow just jumping in to tackle this job without a little foresight.

Default Thanks and more questions...

Thanks for your replies.

Greywolf, its not chain lube I double checked that. Besides, the stain its little dark and greasy, and smells like motor oil.

Black Lab, so your first guess would be the clutch push rod seal the guilty?, yesterday we didnt disassemble the sprocket or the clutch release mechanisim. Today I did it by myself (only the clutch mechanisim) mainly because Im newbie in mechanic, and dont have the the big socket. I can see that the leak could be must likely from the sprocket oil seal, the stains go back until the swingarm. Now, if I want to check it thorougly would you recomend to disassemble everything so that I can physicaly look the oil seal (both). The sprocket one I think its easy with right tools, but the other would imply to dismount the engine and open it?

For the generic seal, have you done that?,

Here are some pics







Thanks again for your help!

Cheers

Gus,
I will try to answer your questions.

As to a generic countersprocket seal; no I have not done a search for that. I had two of them arrive today; one to install and one as back up.

It is hard to tell from your first two photos if you truly have a leak in the countersprocket seal. But, it does appear that your clutch push rod seal is leaking a little. Usually, this seal leaks before the countersprocket seal.

Keep in mind that, when you are riding, any leaking oil gets "flung" rearward on the bike and can fool you as to where a leak might be.

When I did this job, I did not seat the countersprocket seal correctly. It leaked a little. So, I went back and made sure that it was truly seated......... Mistake!!! In doing so, I damaged the seal and it leaked like a seive!!!!! I lost a quart of oil in about 10 miles of riding and nearly pooped in my pants when I went to step on the rear brake; there wasn't any!!!! It was covered with oil. ( I also left a long trail of blue smoke behind me as I "beat feet" back to my garage. I could clearly see it in my mirrors. The oil was getting burned away by my hot exhaust.).

Think about that for a minute, because this is the point I want to make in illustrating my comments in my second paragraph. My countersprocket is leaking oil; a pretty good amount. If I take off the countersprocket and seal retainer, I can see the oil oozing out from behind the seal with the bike running at idle. If I mount everything up and take the bike for a ride, there is hardly any evidence of oil leaking on the left side of the bike, (the same side as the seal). Nearly all of the oil gets blown backwards and across to the right side of the bike from the countersprocket seal leak.

Check out the right side of my rear wheel. It's a mess covered with oil.


This shot is also from the right side.


Now look at the left side. Yes, you can see evidence of a leak, (a major one), but you wouldn't guess that it was from the countersprocket.


That is why I have two new seals today. One to replace the damaged seal I initially installed wrong, and a backup in case I make the same mistake again........

B.

Black Lab,

Thanks again for the explanation. As I dont have the tools to dismount the countersprocket to see if it leaks as you say, Im gonna take it to Suzuki dealer so that they can check that. Still gonna ask for a pair of that seals (one for replace and other for backup), as well as the clutch one.

Wow!, your leaking really was a mess!

Ill take pictures (if they let me to) of the countersprocket off.

Cheers

I just came in from installing the new seal. Everything works fine. Mess? You wouldn't believe the blue smoke that pours off the bike while it is warming up. Filled the neighborhood as the leaked oil burns off.

The actual numbers right off of the seal are:

KOYO - CR 29 MHSA 36 50 6 XLT

These numbers are spaced around the perimeter of the face of the seal.

Good Luck!

Default Parts Manual

I talked today with Suzuki Pro Shop Dealer (there was no mechanic so they didnt checked it), they dont have that parts in stock and would take 45 days to arrive.

Black Lab, do you have the parts manual for 2007 model?, I have the 2004 and its not the same parts number.

Thanks
