hi friend, can you tell me which glue model you used? Is it like glue to screw threads?
Thanks for making the videa! Is there a risk of messing up the timing when you do this job? My seal popped out on a Yamaha VMax SHO VF115LA with 50 hours on it! I found the right tool for the job, and was able to put it back in without removing anything. Trashed the entire marina with this oil slick behind me! Nightmare! Brand new engine too! WTH Yamaha?
You can get timing off, but it's fairly simple to get it lined back up in time. Actually happened to me on this project. Just had to take the belt back off and ensure the arrow marks all points toward each other.
I Have the same problem. Was there a reason for the seal to blow or do you think it is something that just happens? Been looking and dont see alot of information on this. Fixin to head to Louisiana for a week long fishing trip so made a test run yesterday on a local lake when it happened. Was running around 5.5k rpm when the alarm went off and came out of the throttle to see all the oil run out from under the cover. We run as much as 25-30 miles some days and am gun shy now!
Nothing out of normal. It slid back down fairly easy so I think it just wore out and worked itself loose over time. I did read online it does happen on these engines unfortunately
@@deuceliter Thanks brother! That gives me some relief. Did you replace the belt also? Mine is 7/8 yrs old and never been changed but looks new especially with a good oil slick all over it
@Scott Christian I'll be changing it out in the next season or two. Mine looked same lol. I figured since it still looked new and no cracks I'll run it this season and keep an eye on it.
Have you ever had to change your oil pump?
Not yet 🤞
That seal didn't look blown out to me there was no oil anywhere on top of the engine specially on the timing belt if you got oil on the timing belt that should be replaced also the fly wheel bolts never should be reused there torque to stretch and should be replaced according to yamaha
It blew out at sea, and once I was home, it was very easy to push back in place, so in my opinion, it needed replacing as it should take more force to go in than just my fingers. This is why I then decided to replace the old seal with a new one. I didn't know about the flywheel bolts though, thanks for the info!
As for the oil, I cleaned it up when I got back home that evening. If you look close, you can see some places where there is still some oil I missed, though. But you are right, oil had shot everywhere inside the cowl and on top of the engine.
