2018 KTM 690 Enduro: Starter Motor O-Ring Replacement
ฝัง
- เผยแพร่เมื่อ 9 ก.ย. 2024
- My 2018 690 Enduro R seems to have a milling issue where the starter motor plugs in to the case, because of the fact the surface isn't smooth, the O-Ring for the starter motor can let some oil past when the bike is hot after a day of riding. Usually this manifests as a few drops on the floor, and a gunky skid plate. When I went to check and change the O-Ring the first time, it took me forever to figure out how to rotate the starter within the frame, I've done this a few more times since - Hopefully this video can save you some time. Music track at the end is from Bensound.com
Thanks for the great help, I had to take the starter off the bike to rebuild and clean the brushes. It seems that there's only ONE way to take it off the frame...
Checking valve clearance is easier than changing this O-ring on those bikes 🤣
This was the exact video I was looking for 👊👊 I thought I had a bad case for about a month but I new better. I started digging around and found the majority of the oil at the base of the starter. Then I found this video and it sealed the deal for me. Going to the shop to get an o-ring in about 30 minutes
Awesome man, I spent a lot of money and time chasing this down - was hoping the video could help save others some of the same. Thanks!
well made! and yes: saved me a lot of time. apart from that i had a hard time to get the nuts loosened from the exhaust-pipe-fixation; wich never occured, so i removed the nuts with the studs...
Great job! So well done! Thank you!
to magnagaurd, sorry for the late post, I was able to remove my starter on the right side. Had to unbolt the rear brake fluid reservoir, but that was about it on the right side. The exhaust pipe will have to come off on the left side or else you can not pull the splines all the way out. I also unbolted the clutch slave, but not sure if I needed to. Mine is a 2015 690 enduro.
Thank you for sharing was very helpful today!
Well done 👍
Thank you 👍
Funniest part of this fix is, I asked a KTM Mechanic shop about this and got the response "That's not an issue" - I'd say the 1,700+ views and feedback in here... begs to differ 🤓
Well it took me a while to figure out that this is the source of my oil leak. I thought it was the countershaft seal and just replaced that. Rode the bike several times on smooth pavement and thought I had the leak sorted. Just took it for a short spirited ride on some trails and the leak is back. Followed it to this seal and found your video. Now I know what I have to do. Did this solve the problem for you?
Yes, add some liquid gasket, i just kinda smushed some around the new o-ring and re-seated, not a drop since. Over 17,000 miles on my 690 total, I fixed this a few thousand back. Hope it helps!
@@ShutterRev Thank you! I ordered one of the new larger ones last night and will grab some liquid gasket too. Got a trail ride this weekend and will just bring my oil until I have time to do this repair. I like the way you think about this bike(platform vs done deal). Mine's a 2018 Husky 701, but I've got 12,500 miles on it, and have been progressively going over it since I bought in 2021 with 6000 miles on it. It rides crisper and better now than the day I got it, and I love so much about the design of it, that I can't see getting a different bike anytime soon. Will report back. Cheers!
thank you very much! how much time does this job take?
If you follow the turning pattern in the video for rotating the starter inside the frame it will save you some time but everyone's job may differ depending on your skid plate, exhaust, what you are removing before the job, etc. I'd give yourself a couple hours to be safe, especially for the first rodeo.
So there is no perm fix? I see that 19+ models have a different o ring. Also i will be doing this soon. I need to clean very good so i need to pull the starter. If i remove the TB should the starter come right up? Thx for your help.
When I made this video, I did use the o-ring from the newer bikes as it seems a sheet of paper thicker, maybe - at least I tell myself that. lol. I also put some heavy duty RTV around the o-ring before putting it back in.
I am very happy to report after now several rough weekend rides, as well as some yeeting down the freeway, I am not seeing any oil from there yet. So far this is the most permanent fix for me yet. Best of luck with yours - it's still my favorite bike even though it's a bit needy haha :)
@@ShutterRev thanks for the info. Yes the bike is very needy i understand why every year i see 5 or 6 for sale with only 2 or 3k miles on them.
@@magnagaurd Mine has 14,350 miles on it now - and runs so well. I feel like it's more of a platform than a done deal when you buy it. Fuel dongle, foam intake filter, aftermarket exhaust, abs dongle, this fix for the o-ring, various recalls like the shift star, and clutch slave.... and the thing is crisp and amazing all day. I think I was annoyed with something about the bike before each of those changes, or something failed, found out it was a recall, and together = godly shred sled. Long way to say don't give up on the ol gal!!! - haha.
@@ShutterRev mine has 9500 miles. Ive sunk thousands of dollars and hundreds of hours. When i bought it i knew exactly what i was getting into. However it was for better or worse as i wasnt going back to ADV or anything less than 500. Thusly, 690. I also agree its a platform rather than ready to race. I have no regrets though and hopefully once this starter o ring is fixed i can declare her leak free! Originally i thought it was the PVC drain hose as a great deal of grime had accumulated from the base.
@@magnagaurd yeah it also took me a while to chase to that o ring, I should have kept going up, but got focused on lower things - so the bike has a few other seals that didn't need replacing along the way - learning occurred, lol.
I think im having the same issue. But cant tell for sure. Mines leaking right around the same area.
When I was tracking it down it helped to just wash the bike, spray the entire area with cleaner, top the oil, and then go on some dusty rides. Flashlight around after that and see where the drips are sourcing from. Good luck! And if it is this o-ring, not a bad idea to follow the replacement ring with some rtv for an extra layer.
@@ShutterRev thanks I will give that a try. Appreciate it!
